The research method provides a way to solve or a systematic answer to the research problem. It is a framework for collecting, organizing, analyzing and presenting data to study the research problem. Design science research has emerged as an important approach in information systems research. Thus, this study is a systematic review of theoretical literature with a narrative analysis approach to create a comprehensive understanding of key concepts and specialized attitudes around design science research methods. A road map is designed to express how to use DSR to find the answer to the research question(s) about the design of information technology artifacts. The research is conducted with a systematic review method in two main steps. In the first step, the search for reliable sources was carried out using automatic approaches and snowball forward and backward in reliable databases. After the qualitative evaluation of the obtained sources, 52 articles were approved and selected based on specific criteria. In the second step and during the study, based on the narrative analysis method, four narratives emerged: the philosophical foundations of design science research, the theoretical development approach of research in design science, the methodological choice of design science research, the strategy of design science research. Finally, using the narratives and concepts identified in each narrative, a mapping of the concepts and topics related to the four emerged theme of design science research was done and summarized and drawn in the form of a road map. The compiled roadmap presents the process of using the design science research method in the information technology artifacts design in a structured and accurate way for conducting design science research.

One of the most important challenges of context-based information systems with emphasis on cognitive structures is the formulation of receiving and displaying knowledge of cognitive actors empirically in the process of information retrieval interaction. The aim of the present study was to identify the variables of the dimensions of information retrieval context in the interaction process using the framework of the information system and retrieval. of Ingwersen and Jarvelin.

Human-information interaction is a multidisciplinary problem-oriented research field that studies the interaction between humans and information (with its different forms and purposes). In other words, instead of examining the interaction between humans and technology, which is the field of human-computer interaction and human-machine interaction, or examining the interaction between humans and information agents (i.e., the field of librarianship), it examines the interaction between information and people (Jones & et al, 2006).

The present study is of fundamental and developmental type and has been carried out by Colaizzi phenomenological method (1978) in 7 stages. Data collection tool was using In-depth semi-structured interview with 7 experts in the field of information retrieval to identify variables in the interaction process of information retrieval context. Validity is a tool for collecting and content validity data using the experience of experts and reliability is based on the criteria of Lincoln and Goba (1988) based on Credibility, reliability, verifiability. Description and analysis of information has been compared and validated using the results of systematic review and experiences of experts in the field of information retrieval.

The identification of the following variables in the context dimensions of information retrieval in the interaction process has led to the stabilization of search, retrieval and access terms that cognitive actors can consider as information retrieval system designers. The variables of comprehensiveness include: identifying the level and nature of information; Knowledge of the problem; Level of knowledge; prior knowledge; mental models; Identifying temporal and linguistic factors to convey meaning and concept; sociological and psychological factors; action effects; Mental presuppositions, taking into account the skill of formulating search terms, can lead to an increase in the efficiency of the retrieval system for overlapping and matching information in the subject coverage of information and documents, the type of metadata standards, the way information is organized. The variables of the obstacle dimension include: the ability to communicate between the information needs and the retrieved document with an objective attitude (information retrieval systems with an emphasis on relevance) and a subjective attitude (use of the system with an emphasis on user characteristics, tasks and environment); attention to the possibilities of the system in the way of organizing information and knowledge; integrated access to information and knowledge; And eliminating human error in the search leads to discarding irrelevant evidence. The variables of the effectiveness dimension include: applicability and accessibility of information according to ethnic and linguistic characteristics, in other words, leveled accesses; meeting mental needs; filling the knowledge and cognitive gap; the extent of using knowledge and experience and transferring it; According to the functions of the information retrieval system, it can help in expanding knowledge and in identifying and correcting the errors of users in accessing information and knowledge, and it leads to the appropriateness of the results in achieving the goals and providing satisfaction with the information services in the system. The variables of the information quality dimension include: the qualitative aspects of the information in terms of influencing the mental structures related to the need; stability of information in its repeatability; the ability to compare and evaluate sources in the ability to cite and reason information; participation in the creation of new knowledge; Finding resources based on the user's knowledge level; It is related to the user experience and leads to an increase in the qualitative level of user recognition and having the desired structure of the information system. The variables of the quality dimension of the time management process include: extraction of resources based on relevance; Meeting the need for information based on information seeking (targeted search); Displaying the steps and process and components of the information system leads to the quality of search processes from the point of view of the user interface.

As a result, by searching for the meanings and essences of cognitive actors over time according to experience, in order to reach a common understanding in identifying, discovering and creating a deeper understanding, it led to the description and analysis of the cognitive structures of the information and retrieval system framework of Ingwersen and Jarvelin and finally It provides design and access to information in a networked and systematic way.

The approach of cognitive actors in the design of information retrieval system and the role of database designers, user interface designers, information retrieval model designers and search engines are of particular importance in the context of information retrieval. This approach with mental presuppositions with an emphasis on identifying the level and nature of information needs to be recognized and the effects of action over time from the perspective of the user interface. Creating an objective and subjective relationship with interactive and static attitudes reduces human errors in intelligent search and expands knowledge and repairs the knowledge gap, especially by having the desired structure of the information system automatically and by comparing and evaluating resources. The qualitative aspects of the information and process of these steps will be visible and accessible.

Retrieval of experts is a subset of information retrieval that aims to provide a ranking of people who have knowledge in a particular field. Automated expertise work is challenging due to the abundance of expert information and data sources. Many expert approaches in both industry and academia have been proposed using new techniques in information retrieval, data mining, knowledge discovery, statistical modeling, probabilistic modeling, and complex networking. All researchers estimate the relationship between the query and the supporting documents of the expert candidate based on the occurrence of query words in the supporting documents, and they are main and important researches. These models are not capable of semantic communication. Therefore, in this research, the document-oriented method was considered using the LSA recovery model and the use of a time graph

The research method is experimental ones, aside from this, survey and library methods have been used. The method used in current study to retrieve articles on LSA or Latent Semantic Analysis, which is based on the articles of the test collection prepared by Web of Science. These documents include English articles in information science and librarianship from 1989 to 2018 is indexed under the category of information science and librarianship on the website. Total number of these articles were 126924 and queries made by users were provided to all these articles. The retrieved documents were judged by relevance and after judging the relevance of the documents by the participants in the study, the performance of the information retrieval model was measured by the evaluation measurements of information retrieval systems. The result of the calculated measures was compared with the value of each of these measures in the basic model. A temporal graph was used to include the time factor. After that, the authors who had the most relevant work and their value of micro index of social network were introduced as experts. Then ten queries from the present research model and the basic model were randomly selected and given to eight people introduced by the second community for judgment and the results were compared.

According to the innovation used in the current research, which was the application of the information retrieval model of latent semantic analysis, which was finally used to retrieve expert authors, in terms of the amount obtained from each of the information retrieval metrics, i.e., the accuracy level at the level of the first five results, or p@5, mean average precision (MAP) and mean inverse rank (MRR) with values of 0.895, 0.839 and 0.909, respectively, the latent semantic analysis recovery model performed better than the base model. In addition, this is due to the better performance of the retrieval using the dimensionality reduction method compared to keyword matching. In this method, hidden meaning indexing is used, which is a kind of conceptual indexing and uses the statistical method of least squares, and the above indexing is extracted by applying this statistical method. As we know, there are many ways to express a word (synonyms), so it is possible that the query words do not match the words of the document. In addition, most words have multiple meanings (multiple synonyms), so retrieving information based on the concept and meaning of a document is a better approach. LSI assumes that there is a number of latent structures in word usage that are partially blocked by diverse word choices. SVD is used to estimate this structure. The vectors that are obtained statistically strengthen the indicators of meaning more than individual words. The results of other researches also indicate that retrieving documents by matching query keywords with documents is a relatively weaker method. Also, the LSA retrieval model has a better performance in retrieving documents in a large set of documents than in a small set. According to the next innovation of the current research, which was the involvement of the time factor in expert search, and also according to the use of social network indicators and the final relevance judgment, the results showed that the performance of this method is significantly better than the model has been the base. The time factor was included in the retrieval of experts so that people who are no longer alive or who have been around for a long time since their last publication in a certain field are not retrieved. Considering the useful life of publications in the field of knowledge and information science, a ten-year period was involved. After using publication time as the determining factor of expert retrieval, those who had published the most related work were considered as the next determining factor and then the micro indicators of the social network such as degree centrality, betweenness centrality, closeness and special vector are other determining factors that are widely used in scientometric researches and recently in expert retrieval researches. The ten queries proposed in the current research were sent to 8 people who defined the second statistical population of the research, and the results indicated that the performance of the time graph and expert finding performed better by using the factor of the most relevant published works and the factor of micro-indexes of the social network.

Objective

The identify the health-based services of Iranian public libraries in the post-Corona era.

The present research method is qualitative and applied type. data collection tools is a questionnaire. The study population included specialists and librarians, as well as health professionals and nurses who were active members and readers, consisting of 15 library officials, 10 experts and experienced librarians, and 7 active members who were health book readers, physicians, and nurses. The analysis was performed based on the Delphi technique. The research method is qualitative and using Delphi technique. In this study, with the aim of identifying services based on public library health services in the post-corona period, the qualitative approach and Delphi technique were used in four periods.

Findings from Delphi technique showed that among 25 items related to identifying services based on health of Iranian public libraries in the post-Corona era, the cumulative frequency of fourteen items in terms of experts studied in Delphi panel was more than 70%.

Considering the 14 health-based library services, providing these services in the post-corona era can lead the Planners and health officials and the country's medical information system to promote health literacy. It will also help to deal with coronavirus and prevent the risk of its possible return to society.Comparing the results of this study with other studies shows that in recent years the need to provide health services has caused these services as a new paradigm to attract the attention of many health experts. If librarians have a sense of providing health information-based services in public libraries, They will have several organizational and individual benefits such as: prevention of high-risk diseases and increasing public awareness in order to be safe from diseases . In general, it can be said that considering the functions of public libraries and the quality of their role in providing health information services, it can have beneficial effects in the Corona era.

Given the importance and necessity of effective and efficient use of information systems and the study of variables affecting it. the purpose of this study was to investigate the impact of the dimensions of organizational information culture on the use of the information system of Islamic Azad University of Ahvaz.

The study is applied done using the analytical survey method. The study population consisted of all staff members that use the office automation system of Islamic Azad University of Ahvaz (N=350 persons), and 184 individuals were selected as the sample by a simple random sampling method. Data were collected using a researcher-made questionnaire based on previous research tools.

The results showed that the mean of the main variable of organizational information culture (3.753), and its dimensions include information integration (3.483), information sharing (3.443), information proactivity (3.56), information transparency (3.54), information control (3.26), and information informality (3.57) as well as use of information system (3.62) all are above average. In addition, the hypothesis test results showed that the organizational information culture have significant effect on perceived value of information (β = 0.459, P <0.01); and using the information system (β = 0.448, P <0.01) directly and indirectly by mediating role of information value (β = 0.445, P <0.01).

As result the organization should provide the necessary mechanism for institutionalizing the organizational information culture and its dimensions so as to provide conditions for understanding the value of information by the employees and consequently better use of the information systems.Because academic information systems play an important role in the flow of university information; the Perceived value of information will also affect the use of university information systems. In addition, the status of using the information system also indicates that the use of this system has been accepted among employees. However, it can be said that the average use of information systems may be influenced by other factors such as low computer literacy of employees, their unfamiliarity with the value of information systems, importance, and applications of information technology, and people's habits of doing things manually or inefficiently.

The main object of this study is analyzing the components and indicators of the scholarly Publication System in the scholarly Publication databases in terms of access, communication, control, infrastructure, language, materials (information resources), support, technology, economics, evaluation, education, ethics and their characteristics. The research community has been identified by content analyzing and 73 databases were extracted, based on the frequency and approval of experts the sample limited to 12 scholarly publication databases. These include the ArXiv, DOAJ, Elsevier, Springer, Google Scholar, PubMed, Nature, Web of Science, Scopus, National Institutes of Health (NIH), SPARC (Scholarly Publishing and Academic Resource Coalition), and Amazon databases. The checklist designed to study these databases is taken from the scholarly Publication System dimensions. Research findings show that all components have been considered in publication databases and the difference between them returned in scholarly Publication indicators. however, according to the type, age and general policy of the databases, some indicators of components; Like education, economics, and information resources has not received enough attention, in all databases, some components such as technology, support and control and their indicators have an equal importance.

Despite the research on evaluating the role of information system capabilities on organizational performance, the mechanism of this impact is still neglected, especially in the context of project-based organizations. Therefore, the purpose of this study is to investigate the role of information system capabilities in achieving organizational performance by evaluating the mediating role of business process performance and decision-making performance in project-based organizations. The target population of the present study is all companies supplying auto parts and based on the sampling, the research questionnaire was distributed among 108 managers of the mentioned companies. The research hypotheses were tested using structural equation modeling and partial least squares method. The results showed that information system capability had a positive and significant effect on decision making performance and decision-making performance had a positive and significant effect on business process performance. The analysis also showed that decision-making performance played a mediating role in the relationship between information system capabilities and business process performance, as well as in relation to these capabilities and organizational performance. Finally, the findings confirmed the mediating role of decision-making performance and business process performance in the relationship between information system capabilities and organizational performance.

The present study aimed to investigate the relationships between information systems and organizational structure elements (centralization, complexity, and formalization) as well as the effect of e-literacy on the use of information systems.

The present study was descriptive-correlational and survey. The statistical population consisted of Zahedan Governorate experts.Therefore, the research data was collected using a researcher-made questionnaire containing 28 questions in three sections that consist of reviewing the status of e-literacy, reviewing the use of information systems, and reviewing the status of structural elements of the organization.90 copies of questionnaires were distributed in person among the population members after confirmation of content, convergent, and divergent validity and the reliability of the questionnaire by a group of experts. Data analysis was done by structural equation modeling and SMART PLS 3.0 software.

The research results indicated that there were positive and significant relationships between the information system and employees' e-literacy. So that the higher the level of e-literacy of the employees of the organization, the more they will use the information systems in the organization.Furthermore, there were negative and significant relationships between using information systems in organizations and formalization and complexity, so that by using information systems in the organization, we will see a decrease in the level of formality and complexity. While there was a significant positive relationship between the use of information systems and centralization in organizations. So that with the use of information systems, the level of centralization will increase.

According to the research findings, we can be sure of the use of information systems in the organization by hiring employees with high information literacy or holding training courses by using different methods of e-learning, mobile learning, and face-to-face learning to develop staff information literacy. So we can ensure the actual use of information systems in the organization; as a result, it will lead to less formalization as well as more complexity and higher centralization in the organization

The increasing growth of web usage has made the importance of search engines and their quality assessment more responsive to users' needs. One of the approaches to quality assessment is user satisfaction. The use of a search engine depends on user satisfaction, which is a measure of the quality of the search engine. Many search engines have been built in Iran, as well. Some of these engines are widely used to search for information on the web, and some are found in a database Iran scientific information database (GANJ) is one of the databases that have its search engine. It contains nearly 530,000 dissertations and thesis and is one of the key scientific databases in the country with many users. Therefore, assessing the satisfaction of users of this system with its broad audience is crucial. In this research, indicators based on the EQOAL model were developed to evaluate users' satisfaction with the GANJ System. Indices developed based on the Delphi method were screened and localized to assess users' satisfaction with GANJ System. User satisfaction was also assessed using an EQual questionnaire. The results of the data analysis of the 156 questionnaires collected show that usability, information, and service interaction are the significant determinants of users' satisfaction with the treasure system, respectively. In terms of usability, the ease of working with "GANJ" is a top priority. Likewise, the ease of interaction with the system and the apparent attractiveness of the system were introduced as the main factors.

The main problem described by Wittgenstein is language, which initially conceives language as the illustrator of the facts and later in its second philosophical period, as a form of life. This paper seeks to analyze the dimensions of information storage and retrieval in light of Wittgenstein's picture and language games theories.

Wittgenstein's analytical method used in both of his books is a method of analysis or argumentation and a conceptual-linguistic method. This research was carried out by using analytical method and literature review. Information was gathered by searching for printed and electronic sources (related articles and books).

Analysis of the information storage and retrieval systems from texture, knowledge representation, indexing, spoken communities, natural language, meaning and relevance and access to content dimensions showed that the information storage and retrieval systems in the realization of their main goal, which is the transfer of information from the source of information to the searcher is faced with fundamental semantic problems. The information storage and retrieval system that provides well access to information does not function well in access to the intellectual content.

The process of analyzes and basic assumptions in the information storage and retrieval systems implies that the information storage and retrieval systems are designed based on the search indexes and expressions with static meanings and the rule of the individualism and subjectivity approach influenced by the picture theory of language. But the text as the source of information that feeds the information storage and retrieval system is no longer the area of ​​language games, and it is impossible to conceive of what the indexing system considered constant conceptions for the text as the ultimate and definitive meaning of the text.

The main goal of this study is to present fuzzy logic-based method in order to evaluate preparedness of organizations in adopting information management system. As a case study, this model was implemented in Zahedan Municipality. In addition to above mentioned goal, the process of the study specify the weakness and strength of organization under consideration in adaptation and implementation of these systems. In this study, using the factors extracted from previous studies and receiving views of 20 IT experts, 19 indexes are selected for task process, and preparedness of Zahedan Municipality [equal to 0.467] to accept information management system (based on the numbers between 0 and 1) is calculated, while using verbal expressions of experts and specialists associated with organization. The weakness and strength of Zahedan Municipality in this path are specified as side effect of research. Development and expansion of network in the organization and knowledge of personnel coming from positive effects of IT applications in increasing productivity and performance efficiency are determined as reliable and strong. Furthermore, organization has weakness in electronic communication with citizen and other (upstream and counterpart) organization in city, province, and country and up-to-date information banks and clarity of available data in them.

One of the most important goals of information systems is to provide services based on users’ cognitive characteristic. This increases the system efficiency, user satisfaction and interest in the use of information systems. Since e-learning has been widely used around the world in human-computer interaction domain, in this research the e-learning environment has been chosen to evaluate the model. The goal of this research is performance evaluating of an intelligent e-learning system is compared with a simple e-learning system. The intelligent e-learning system which is based on user’s personality dimension and emotion. In this research, the intelligent e-learning system use the model which desirability as an important variable to calculate emotions and interact with users based on this model. The model can detect users’ emotion based on personality dimension, user’ goals, and environmental event. Evaluating of the model is in two steps: the first step is checking generality of the model in different learning domains and the second one is to determine whether presenting suitable actions to users after predicting their emotion status has an influence on satisfaction and learning rate or not. In the first step, the model has been evaluated in two real e-learning environments which are designed to teach: “Introduction to computing systems and programming” course and “English language vocabulary”. The results show that accuracy in predicting desirability in emotion module in e-learning environments with different materials learning are the same and they confirm the generality of the model. In the second step, two e-learning environment which is designed to teach English vocabulary. The e-learning environment has been implemented in two versions, i.e. a basic system with no intelligence and an intelligent system which can predict a user’s desirability. The intelligent e-learning environment acts according to the user’s status based on her/his desirability. The results in this step show that users believe the intelligent environment is believable and more attractive than the basic one. Also, they express this environment can understand their emotional status and react based on it, and it can improve their learning process.

In order to achieve strategic goals, missions and desirable information technology, organizations require comprehensive and suitable plan. Given this, IT strategic planning serves as an integral part of organizations strategic planning. A fundamental question arisen is that what affects information technology planning? In the present study, using TOE model, the variables are categorized into technologic, organizational and environmental factors. This study was conducted in the National Iranian Oil Company (National Iranian Drilling Company (NIDC) in Ahvaz). The subjects consisted of 110 executives, councils, bosses and IT experts. Due to small number of subjects, the sample were set equal to the population. A questionnaire was designed to data collection whose reliability was confirmed and its validity was estimated 0.96 based on Cronbach Alpha. For data analyses, software's SPSS and PLS were used. The model was described by G.O.F criteria 62% characterized with strong fitness so that of eight hypotheses, five one were accepted and three were rejected. A relation between information system infrastructure, knowledge management, participation, environmental assessment to IT strategic planning and the opposite was true for relationship between information system maturing, change management and congruence to successfulness of information technology strategic planning.

To identify the position of Management Information System (MIS) in National Library of Iran (NLI) based on middle managers’ viewpoints.
The qualitative approach using case study. The population consists of all NLI middle managers counted 14 according to organization structure. Data gathered through interview and analyzed using content analysis and coding system of Grounded Theory.
Different kinds of managerial information are required by managers and there are plenty of ways to acquire such information. Managers mentioned MIS advantages, the challenges of lacking to have MIS and limitations for MIS establishment.
NLI managers can handle many problems using MIS. It can lead library to its goals. However, the vital point to succeed is preparing the required condition before the establishment.

In recent years, lack of appropriate understanding of IS user requirements, has been one of the most important causes of IS development failure. Therefore, many methods were introduced for better analyzing user requirements; some of them were philosophically different. Organizational semiotics (OS) is one of these methods, which with phenomenological and action-oriented view, tries to get better system requirement analysis. In this research, first, organizational semiotics and SSADM was compared, with focus on their ability to elicit and analyze IS user requirements, and then, OS was applied in analyzing an IS requirement analysis case. Research findings show that OS in many dimensions is superior to SSADM; although SSADM has superiority in few dimensions too. Therefore using OS can help analyzing IS user requirements more appropriately.

Actor network theory as a qualitative approach to study complex social factors and process of socio-technical interaction provides new concepts and ideas to understand socio-technical nature of information systems. From the actor network theory viewpoint, agricultural climate information system is a network consisting of actors, actions and information related processes (production, transformation, storage, retrieval, integration, diffusion and utilization, control and management), and system mechanisms (interfaces and networks). Analysis of such systemsembody the identification of basic components and structure of the system (nodes) –thedifferent sources of information production, extension, and users, and the understanding of how successfully the system works (interaction and links) – in order to promote climate knowledge content and improve system performance to reach agricultural development. The present research attempted to introduce actor network theory as research framework based on network view of agricultural climate information system.

Organizations have the different patterns of behaviors on management practice and the use of systems during their life cycle and due to rapid growth of information technology، the application of appropriate technologies is becoming an essential part of business، as well. The adaptation of appropriate management systems on different stages of organizational life period will affect on sustainability of the firms and success to move to next stage and alignment and collaboration schema of IS/IT and business requirement affects on management effectiveness at every stage. This research investigated the significance of relationship between management behavior and IS/IT usage and the generic approach selected by companies. The results showed that organizations have chosen different approach during their life cycle and as they faced with unique challenges on each stage، a common practice on using information technology and applications became part of organizational life cycle. A generic model for information technology usage on organization life cycle was also developed that will assist organizations to select and develop IS/IT plans which addresses the requirements for each stage of life cycle.

Successful implementation of an executive information system (EIS) is not an easy job for most of organizations. Out of many factors to be considered, the success or failure of an EIS ultimately depends on how well the implementation process is managed in terms of both technology and users. This article with regarding to senior managers’ information needs to make strategic decisions, was about to recognize critical success factors in implementing EIS in the Iranian organizations. Statistical Population in this research included managers and experts in Petroleum Equipment Industries Corporation (PEIC) and its subordinates. A questionnaire was developed by researchers for gathering data from sample population. Research findings based on factor analysis was indicative of following critical success factors for implementation of EIS: 1) Development of an appropriate conceptual model; 2) a participative approach in design and development; 3) a relevant technology; 4) role of IT Department; 5) project management of EIS; 6) supportive role of senior management; and 7) software capabilities. The model explained 59 percent of the variance in successful implementation of EIS. Therefore, it should be bear in mind that there are others CSFs which were not recognized in this research.
