This study aimed to knowledge mapping of Digital Libraries (DLs) field in Iran. This is a scientometrics study. In this regard, Social Network and co-word analysis methods were used. 554 research resources such as books, national and international journal papers, conferences articles, and MA and Ph.D. Theses in Iran up to 2013 were studied. Researcher made checklist was used to collext data. Also Gephi and VOSviewer softwares were used to visualize and analyze the subject networks. Researches in the field of DLs were classified into 10 research topics and 59 Subtopics. Findings showed that "Evaluation", "Digital content and collections", "Architecture, systems, tools and technologies" and etc. are higher frequency research topics. Also "Evaluation", "Metadata", "Content preservation and security" and etc. most central and core subtopics in subject networks; Moreover subtopics such as "Electronic publishing standards", "Use of taxonomies to provide unified and organized access to various digital repositories", "Digital preservation systems", "Resource sharing" and etc. are research areas that paied less research attention in Iran. Also results reflect that less researches pay attention to the technical and experimental domains. This show that domains co-occurrence structure with nearly two decades of studies in this field, compared with international studies, isnot matured and correlation between clusters are little and unbalanced.

Perception of icons is one of the most important elements of graphical user interface in information systems that is affected by personal and environmental factors, including user's mental models. The present study tended to investigate factors affecting on the user's mental models of icons in digital library software. This is an applied research using qualitive and quantitive approach. Gathering data tool in quantitive section is researcher-made questionnaire and in qualitive section is semi-structured interview. The participants consisted of B.A. and M.A. students of knowledge and information science in Shiraz University and Shiraz University of Medical Sciences and Shiraz University librarians, 174 persons. According to the results, " experience", "icon's functions", "external characteristics of icon", and "context" are four main categories affecting on user's mental models of icons. "Experience" includes user's former familiarity and experience and " icon's functions " includes compatibility of icon function with its picture, referring the icon to unknown and uncommon function rather than common function, common function in different applications and special functions of some of icons. " appearance characteristic of icons" includes color, size, clarity, context and complexity of icon. It hasn’t been any research that investigate factors affecting on user's mental models of icons in digital library software. Recognition of factors affecting on user's mental models can help digital library software designers to design the icons that have more consonancy with users’ mental models and eventually provide users satisfaction.

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.

Cloud computing introduces new capabilities to organizations such as: cost efficiency, scalability, access to global markets, and ease of use, flexibility and rapid adaptability against environmental changes. Cloud computing provides an important role in organizational innovation and agility. In spite of great opportunities that this technology brings to organization, in many of organization, especially in developing countries, adoption and migration rate is low. Major problem is that in previous studies of cloud computing adoption, limited aspects have been taken into Consideration. In fact, a comprehensive framework that includes all affecting factors didn’t develop. In order to address this issue, this research by systematic literature review of previous selected research, using the Meta-synthesis approach to qualitative analyze and synthesize different factors affecting the adoption of cloud computing. Finally we propose the comprehensive framework. In this research after systematic search, 57 papers are selected for full content review. Based on Meta-synthesis approach, 94 Concepts, 20 sub-categories and 9 categories of adoption factors recognized and, a cloud computing adoption framework developed. Proposed framework is composed of nine categories such as the economical, technological, organizational, cultural, innovational, regulatory environment, business environment, infrastructure, knowledge based and individual. This framework validated by experts’ judgments. For Expert selecting, the snowball sampling method is applied and in a focus group meeting the adoption framework reviewed and finalized. Proposed adoption framework conducts manager to gain effective and efficient view of adoption factors before cloud computing migration and design strategic planning.

The objective of the present study is prioritization of the quality of information service centers in terms of Kano’s model and asymmetrical performance impact. This research is an applied research in terms of purpose, and is a descriptive survey in terms of data collection. A number of students at Tehran University at different educational levels, as clients of the Central Library during the educational year 1394-1395, served as the participants of the study. According to the information center of the Tehran University library, the number of clients during the period under investigation was 137,042. Using the Cochran formula, the sample size equals 375. Applying a random stratified sampling, the researcher collected 376 completed questionnaires. The collected data were analyzed through applying statistical tests, transforming the Likert scale into Kano’s model and asymmetrical performance impact formula. The results, generally indicate that the “services effect” factor, associated with the performance services category with low performance; “information control” factor associated with the category of motivational services, with low performance; while the factor “space and location of the library”, associated with basic services in high performance. Therefore, the prioritization of the measures to promote the quality of the library services, with regard to the Libqual dimensions, would be: (1) To promote the performance level of the factor “service effects” from a low- performance to a higher- performance level. (2) To promote the performance level of the factor “information control” from a low level to a higher performance level as well. (3) To sustain the performance level of the factor “space and location of the library” as it is.

The purpose of this study was identify view point of faculty members and professionals of knowledge and information area and related sciences towards information technology in selected Isfahan universities about variables in Information Architecture and providing solution for organizing. This study was survey and questionnaires were used for data collection. The population of this study included all faculty members and professionals of knowledge and information science and related science to information technology of Isfahan universities who have been working in 1394.They were 110 persons. For data collection the questionnaire in the five point Likert Scales was used. According to research results, in most cases their points of view about information architecture are different. Only in relation with the impact on corporate investment in information technology cannot say that their points of view are different. The result showed that view point of faculty members and professionals of knowledge and information science and related science to information technology of Isfahan universities is concerned in two approaches, Enterprise Information Architecture and user experience Information Architecture. According to Information Architecture the best suggestion to organize information is to create checklist from infrastructure level to the user interface level.

The purpose of this research was to find out the reaction of Web Search Engines to Metadata records created based on the combined method of Rich Snippets and Linked Data. 200 metadata records in two groups (100 records as the control group with the normal structure and, 100 records created based on microdata and implemented in RDF/XML as experimental group) extracted from the information gateway of Iranian Content National Consortium (INCN) were analyzed through an experimental approach. The metadata records of two groups were published on an independent website (www.rnikzad.ir), and were introduced to Google and Bing search engines directly. The using a checklist, the status of index ability and visibility of the published metadata records in two search engines were examined. Findings show all the element values of the metadata records of two groups indexed by Google and Bing, and were visible in the search results; but the records were not displayed in the search results semantically like the metadata records created in rich snippets methods only. In the other words, the spider-indexer software of Web search engines are not able to identify and index the metadata elements (tags) created based on microdata method and implemented in RDF (as the syntax of linked data method) and, the search engines cannot display the records in the search results semantically. So Web search engine are not adaptable to the standards of the semantic web.

Gamification is one of the most important method in acquiring and improving user engagement and challenging competitors. It defines as using game based thinking and game elements in non-game context to encourage users, solve the problems and to gain certain behaviors. Developing a conceptual model for improving the process of obtaining data in thesis and dissertations registration system is the goal of this paper. The designed conceptual model consists of four steps. During these steps, business goal, users and their desired behaviors are defined. Using this information, the conceptual model is developed in the fourth step.

This research aims to investigate accidental discovery of information in using of social networks and online communication in Shiraz University.

This is an applied research that uses descriptive analytical techniques. In order to determine the validity of the questionnaire the comments of a number of experts and professors were asked, and by using Cronbach’s Alfa its reliability(./88) was determined. The research population consisted of 3434 students of the faculty of Humanities and Engineering.. A sample of 346 students were randomly selected for the research, based on the Krejcie-Morgan sampling table. The collected data were imported to SPSS version 21, and analyzed based on descriptive statistics.
Findings: Results show that the respondents were using resources more than average. They also know Social Networks and Online Communication a useful tool for purposeful gathering and accidental exposure to information. The majority of respondents use information gathered accidentally in their various activities, and store or share it.

Social technologies and online communication are useful tools to achieve the targeted information and also to obtain untargeted information. Accidental discovery is an information gathering method equal to targeted information-seeking. Obtained information by accident is useful in the sharing of knowledge. It can also change the user path, guide him towards a new idea and assist in solving problems.

The importance of theinvestigative social networking site: Researchgate services as a means to communicate, sharing of knowledge and experiences among researchers is known. This study aimed to identify expectations of Researchgate, from the perspective of Engineering researchers are members of this network. This study is Survey and descriptive research and the mixed metod was used. The sample consisted of 12 interviews in qualitative and 144 researchers in questionnaire and quantitative research. The results showed that, engineering researchers after Researchgate have highest membership on social networks LinkedIn and GoogleScholar, and on average, each researcher in research social networking sites more than two. In connection with the expectations of Researchgate, the component "associated with citation databases and the use of information according to which" the frequency of the highest importance for researchers. Knowing the number of Cites is very important for researchers, so they expect RSNS reflect reliable feedback from their scholarly activities. also they expect the most suitable criteria to facilitate and accelerate scientific-scholarly activities.

Iran’s proper status in the development of science and knowledge at the international level represents the institutionalized decision making system in this sector of the country. Besides, Iran’s strategic documents always emphasize on the formation of a place for the country’s knowledge and technology. Regarding to the development of technologies and IT infrastructures, this paper focuses the technological functions of scientific information management in the research and resource management value chain and analyzes the facilitation of the research services enhancement in the country. The approach of the paper is almost qualitative. At first, we identify the scientific and technological information value chain and its stockholders, applications, requirements, based on the previous documents, and international documents including goals and strategies, plans and actions. Then, we recognize the classification, and the definition of IT based on service systems. Finally, we present the IT functionality of scientific information management and research value chain based on the stockholders as a conceptual model.

Due to medical researchers need for updated and valid scientific findings in their research area, it is important to evaluate medical journals. On the other hand, researchers are looking for prestigious journals to publish their articles in their field of activity. Because much of the medical journals in Iran published by Universities of Medical Sciences, this study aimed to evaluate Iranian Medical Sciences Universitie's research journals in Google Scholar citation database between 2010-2014, with emphasis on both scientific impacts: The Journal Hirsch index and Journal Impact factor. In order to collect data the researchers used publish or perish, which is a citation analysis software. Data were analyzed by descriptive statistics and Spearman correlation test using Microsoft Excel and SPSS16. The results showed that a total of 38,717 articles from 130 surveyed journals in the period of study was indexed in Google Scholar and these articles had received 61,938 citations, i.e. 1.6 citations per article. Total average of Hirsch index in study population was 7 and total average of journals impact factor was 1.31. Spearman correlation test results showed that the journal language and number of journals articles have a significant positive correlation with the number of received citations, journal Hirsch index and journal impact factor. The relationship between journal impact factor and Hirsch index was significant too. It seems that due to the high correlation between journal impact factor and Hirsch index, these two indicators can be used as complementary elements in evaluating journals.

Investigated the information need and information seeking behavior in the Iran manufacturing industry.
Method/Design: To gain a deep understanding of the issue, we used grounded theory approach. 25 manufacturing firms operating in the Isfahan Science Technology Park were selected purposefully. Data was obtained from 20-30 minute semi-structured interview with all 25 companies’ managers.
Findings: In emerged that the companies` information needs are variant based on their fields of work and by the environment. Furthermore, companies use three sources (persons, organizations, consultants) to obtain information. These resources include: market resources (experience and knowledge, market observation, exhibition and advertisements, other organizations, and communications); scientific resources (publications, imitation, experts and specialists knowledge and experience) and other resources (internet, media, and customers). Companies’ information seeking behavior ranges from easy to stringent behavior

Internet of Things (IOT) is a newly developed concept in the world of technology and communication which provides the ability to transfer technological information to everything, including human, animals, or objects, through communication networks such as internet or intranet. Biometric technology offers various applications. The main objective is to provide an appropriate alternative for control systems with traditional access. It is also utilized for personal protection or corporate finance. Simultaneous application of Biometric technology and Fast Identity Online (FIDO) may advance interaction with objects and authentication of those who want to access crucial information. Furthermore, the authentication of individuals is a more accurate and faster process. Whereas in the traditional techniques, this process is much more costly and time-consuming. This article presents a new approach for utilizing biometric technology in IOT, in order to manage biometric in IOT. The results demonstrate fingerprint biometry obtains the highest priority as compared to other biometric techniques used in IOT, while it imposes the lowest implementation costs. Moreover, it provides a high level of security for the system management.

Nowadays, analyzing user behavior on search engines is highly regarded. Lots of options in retrieved results in the search engines, makes users to choose. Once the selection is extremely complex, people will think the simplest decision rule, they decided that not to decide and select. Psychologists know this situation the consequence of "choice overload". Bons (2008) believes that choice overload is the ability of process the information by the people to select. In simpler terms, dealing with a lot of information, lead to the negative results. This study has been done with the goal to identify modulators of Google search engine. The present study is a survey and an applied research. Using stratified random non-relativistic sampling, 72 MS and PhD students of faculty of Psychology and Educational Sciences and Engineering of Ferdowsi University were selected as a sample. The tools used for collecting data were standard questionnaire (maximizing scale by Schwartz et al 2002) and HCI browser. The results showed that regardless of the personality types (maximizer and satisfier) and only by regarding of the type of search, you cannot say a definitive statement about choice overload theory. Considering two variables of personality and search type, a significant difference between satisfaction of two types personality from the number of retrieved results were observed.This means that maximizers are, in both special and general search, more satisfied from small results than large results (choice overload). But satisfiers, in special search, the number of retrieved results had no effect on the satisfaction of them (the non-occurrence of choice overload). Also in satisfiers, in general search results, there was a significant difference between satisfaction from the small and large retrieved results. However, according to their personality and serendipity theory, with increasing the retrieved results, not only choice overload did not occur, but satisfaction of them was more. Hence we can the importance of two factors: the type of search and personality as modulators of choice overload. In general both personality types were satisfied with the speed of retrieve of results in Google search engine.

A significant amount of available information is stored in textual databases which contains a large collection of documents from different sources (such as news, articles, books, emails and web pages). The increasing visibility and importance of this class of information motivates us to work on having better automatic evaluation tools for textual resources.
The automatic summarization of text is one of the ways to prevent the waste of users’ time. The extractive text summarization consists of the extraction of the more important sentences with the purpose of shortening input text while maintaining the topics covered and the subjects discussed.
In this paper, we have tried to improve the accuracy of the extracted summaries by combining natural language processing and text mining techniques. By modifying the mentioned algorithms and sentence scoring measures, accuracy is increased as compared to the previously used techniques.
Part of speech tagging is used for calculating coefficient of words’ importance. Using this approach will in turn help us with to pick the more meaningful words and phrases that will result in better accuracy of the system.
Graph similarity‘s methods are used to select sentences. Changing weight of the selected sentences in each step leads to solve the redundancy problem.
Standard evaluation measures such as “Precision” and “Recall” are used to evaluate results based on a Persian corpus.

Finding research gaps in the area of Data and Information Quality and finding ways to enhance the quality of data and information in information systems would help researchers and experts to undertake applied studies in this area. On this basis, the present research will try to the present research will try to categories of content analysis of existing research in this field at Iran and abroad. We use Systematic review method in two main section. First, Searche about evaluation of data or information quality. In the following, second section, we evaluated and analyzed research. Results of the study revealed that according to the input criteria, in the foreign section, 65 out of 922 items, and in the local section, 24 out of 516 studies described the different aspects of the quality of data and/or information. 24 of these items focused on developing models or specific frameworks. Moreover, it was clear that 77 quality dimensions were identified and examined in the articles of the foreign section. However, only 27 dimensions were discussed in the local section. Also, findings revealed that in the information systems, Completeness dimension was the focused subject of most research papers locally and internationally. Research from 2000 til now show that there is some gap in research about data or information quality assesment, especially in persian.

The purpose is review the literature to identify the epistemological and theoretical approach to the folksonomies and compare them with the theoretical foundations of controlled vocabularies. This paper is a library research. A review of the literature, identify and review theoretical approaches related to the folksonomies includes Critical social theory, Social constructivism, Relativism, Derrida’s deconstruction and hospitality and compared them with the theoretical foundations of controlled vocabulary .
In theoretical approaches emphasized that people and users are different and have their different experience and knowledge, So they formed different concepts in mind and used different words to express their concepts that are different from one user to another user. These diversity concepts is represented in folksonomies. But in controlled vocabularies, concepts that only exist in the minds of catalogers is represented which may different with concepts that are in the minds of users. On the other hand, relativity can create the lack of uniformity and it is considered a disadvantage for folksonomies. While, uniformity is considered in controlled vocabularies and is an strength for them. In conclusion reviewed theoretical approaches provide theoretical basis for judging folksonomies capabilities, advantages and disadvantages and comparing them to controlled vocabularies, but must consider findings in future researches.
