The main purpose of this research is investigation of effect of the users’ religiosity on their relevance judgment. 

This research is practical in terms of purpose and was conducted using the descriptive survey design. The statistical population of the research consisted of all fourth-level doctoral students at Al-Zahra University, whose number was 69. Mean and Standard deviation were used to describe the statistical data, and Pearson’s correlation coefficient and simultaneous regression analysis were used to analyze the data. In order to collect information about the level of users’ adherence to religiosity dimensions, Glock and Stark’s religiosity questionnaire (1968) was used which includes 26 items arranged in 4 dimensions of beliefs, emotional, consequential, and ritual. Then, in order to determine the degree of relevance judgment, 6 simulated work tasks were defined and the most important criteria of relevance judgment were evaluated during the execution of work tasks. First, the users searched on the topic of work tasks in Persian paper databases, including Magiran, SID and Ensani Portal (Iran’s Humanities Portal), and they selected 10 papers for each task. After reading each scenario and the demand related to it, users evaluated the papers related to each scenario in a related, somewhat related, unrelated format. Therefore, each user evaluated 30 papers related to 6 work tasks.

The findings indicates that among the religiosity dimensions, the interactive behavior of users showed a higher average than the interactive performance and relevance judgment. Moreover, the average of practices dimension was the highest, followed by belief dimension, and emotion dimension. Finally, the works dimension showed the lowest average. The results of multiple regression test showed that users’ ritual and behavioral dimension (such as worship, prayer, participation in special religious rites, fasting, etc.) and belief dimension and religious beliefs are effective in increasing relevance judgment, but the two affective and emotional dimensions have nothing to do with the judgment of users. In other words, despite the change in the emotional dimension of the users, i.e., the change in the degree of emotions, imaginations and feelings related to having a relationship with a divine entity such as God or an ultimate reality or a supreme authority, their relevance judgment would not change. Furthermore, despite the change in the ‘consequences dimension’ of religiosity, i.e., the change in the effects of religious beliefs, actions, experiences and knowledge on the daily life of users, the level of their relevance judgment did not show a change.

Originality/value: 

The present research is the first research that has explored the effect of users’ religiosity scales on relevance judgment. According to the findings, it is suggested that system designers and experts, in addition to considering technical issues and hardware and software equipment, should also manage the interactions of users with the system and consider the different conditions and situations of users. Librarians, while knowing the society in which the users are located and considering the religious context of the society as well as knowing the religious approaches of the users, can provide the necessary guidance to them when retrieving information.

 The objective is search behavior analysis and evaluation of relevance judgment of the users of information retrieval in the web hyperlink environment. In this regard, the pattern of the web information retrieval behavior of these users were explained and the rate of satisfaction with information retrieval system, the rate of the user trust on the results and effectiveness and ease of using the results and the rate of results relevance from user’s viewpoint was investigated. Also, the significance of the difference of the mentioned factors between the students of the field of information science and other fields was statistically assessed.

 This research is applied / fundamental which has been performed with combined method. The research population included 5784 students of master's and doctoral degree of information sciences and other different domains of sciences in Shahid Bahonar University from 2017-2018, that with purposeful sampling method, 50 students were selected. From this, 37 persons participated in the research process and the rest was omitted due to lack of cooperation in some stages of the study. This study was performed with the aid of a two-question scenario, one question relating to the academic field and one question in their specialized field. This study began through observation, searches and recording them with the aid of Camtasia Studio version 9. Then, the searches were observed and turned to text with the aid of word software. The text files were coded with MAXQDA version 10. The categories obtained from text analysis were used in explaining the users' pattern of information retrieval.
In the quantitative stage, for assessing the satisfaction rate of information retrieval system, the rate of users trusts in the results and ease of using the results and rate of relevance of the results from these user’s viewpoint, the structured interview (5 factors in the form of 15 questions in Likert scale) was performed and the data was collected and analyzed using SPSS software version 23. For evaluation of the variables, single sample t-test and for investigation of the statistical significance of the difference between two groups of information science and other fields, independent two-sample t-test was used and the average of the variables scores was compared with the mean and theoretical rate of 3. If the considered sigma score is more than the theoretical rate, it may be said that that criterion is in a desirable level. In assessing the reliability, the internal consistency coefficient above 0.7 was confirmed. Also, the validity of the interview (internal and external) was confirmed by 5 experts.

 Investigation of the search behavior analysis in completing both tasks in the qualitative section showed that among the browsers, Firefox and among the search engines, Google was more commonly used. Users completed each search in a 5-stage pattern: beginning of search, keyword codification, search navigation, retrieval and results evaluation, information extraction. In the beginning stage of more searches search engine has been used and using electronic address of the database or considered website is in the next ranks. The greatest frequency was related to simple search. In completing the first task, scienceDirect database and in the second task completion, Sivilika had the greatest use frequency. In keyword codification, the general to specific technique had the greatest frequency and after that keyword change, changing the number of words of the search term (including omission, addition and replacement), specific to general technique, simultaneous use of both general to specific and specific to general technique have been used respectively. In the search navigation, following links and menus had the greatest use. After that, following the results in the same tab, following the results in the new tab, using return key for going to the results tab and using back and forth keys are placed. In the fourth stage, often people only investigated the title of articles and congresses and reviewing the title and abstract of the papers are in the next stages of use. In the fifth stage, the subjects downloaded and saved as PDF and or their complete text could be accessed through DOI code.
The qualitative findings showed that most of the students were studying in the department of humanities and after that the group of basic sciences, technical engineering, agriculture and veterinary department. Also, the average of all investigated variables in both groups of information science and other fields has been more than average and in a desirable status. Among the variables, ease of search and achieving the results, the average scores of the information science group is in a lower level than other fields and the average score of satisfaction rate and results relevance among the students of information science is in a higher level than other fields. Also, the results showed that there is no statistically significant difference between two groups of information science group and other fields.

 Explaining the different patterns regarding the user features and the texture they are in will help the information media in responding the clients' requirement. Also, designers empower the search engines to design more interactive and user-friendly interface and instruments. Increasing the efficiency of information retrieval systems and user’s skill optimizes the search process. Intelligent retrieval systems have a considerable role in information interaction. In more and better interaction of the user with information systems, meaningful and relevant information may be obtained and this depends on perception of information systems of the users' needs and behaviors.

Aims to identify the role of document readability level and the objective complexity of the work task on students' relevance judgment and document ranking.

Quantitative content analysis was utilized to determine the readability level of texts. The statistical population of the research included 2825 graduate students of Shiraz University of Humanities. To determine the sample size, due to time-consuming process of relevance judgment, students’ time constraint, and sample size of similar studies, a non-probability sampling method of voluntary type was used. Two work tasks were designed based on Borland's (2000) Repository of Assigned Search Tasks and experts' opinions. After confirming the validity of the work tasks by the experts, searching through the Persian article databases, including SID, Magiran, and Noormags, four relevant, four partially relevant, and two irrelevant articles were selected by five experts The articles were divided into difficult and very difficult levels by determining their readability levels using Flash-Diani readability formula. In the next step, ten articles related to two work tasks were scored by users in a six-level spectrum (from entirely irrelevant to entirely relevant) then ranked based on the relevance degree (from 1 to 10). Data was analyzed using social science statistical software version 23 (SPSS), and T-tests and Mann-Whitney U tests were conducted.

The results showed significant difference between students' relevance judgment with different readability levels. Students rated documents with difficult readability levels more relevant than documents with very difficult readability levels. In addition, considering the role of readability level on the ranking, there was a significant difference between the rankings of relevance in the documents with different readability levels according to the students. Documents with difficult readability levels were ranked lower in terms of relevance. Therefore, students performed finer on rating documents with difficult readability levels.  Findings about the role of complexity level of work showed that objective complexity of the work task affected the students' relevance judgment. The retrieved documents related to the simple work task were found to be more relevant than the complex work task. Regarding the role of complexity level of work tasks on ranking, findings  revealed that the level of objective complexity of the work task affected the ranking of documents, and the simple work task ranked lower in terms of relevance ranking. Therefore, students performed finer on the simple work task than on the complex work task regarding relevance rating.

The role of level of readability of documents and objective complexity of the task affected relevance, judgment, and ranking. Further research on the effect of these indicators on relevance judgment  can improve the design of information retrieval systems and increase the quality of the relevance and ranking algorithms.

Relevance is one of the concepts that many researchers consider it fundamental in information retrieval. Recently, relevance has also been given attention in Iran about which multiple studies have been conducted. However, there is no clear understanding of relevance-related studies in Iran. Therefore, the current research aimed at exploring related research through a systematic review. To find the publications, questions and inclusion/exclusion criteria were initially determined. Several databases were searched using related keywords. Finally, 108 publications were selected. The software Excel was used to extract and analyze the data gathered. Publications in the field of relevance could be classified into 6 groups including recall, precision, recall and precision, relevance feedback, relevance judgment, and review resources. The results showed that most of the studies are conducted in an objective way and the researchers considered search engines more than other information retrieval systems. Moreover, the results also indicate that the recent studies are related to relevance judgment and experts in Knowledge and Information Science have been unwilling to do research on relevance feedback. While the quantitative methodology is used more frequently, the qualitative approach could also be very effective, especially in the subjective relevance and user-friendly context.

The purpose of this study was to determine correlation philosophic mindedness on precision of user’s information: retrieval from scientific information databases.

Research method was quasi experimental, and the population consisted of 42 scientific researchers from different disciplines that selected based on purposeful sampling in Tehran. The data gathering instrument was the Mirsepasi and Soltani’s philosophic mindedness questionnaire that has 60 items. Soltani questionnaire measures four compounds of philosophic mindedness in 4 degrees Likert scale. Cronbach’s alpha for philosophic mindedness was 0.91 two pages of the retrieved results (80 records) were examined by the users in terms of relevance to their real information needs.

research Finding showed a significant correlation between the mean values of the philosophic mindedness of the users and the precision of the retrieved results. 50% of users have high and good level of philosophic mindedness and only 11% of users have law level of philosophic mindedness. There was significant relation between demographic characteristics of gender, age and employment status, degree and job with philosophic mindedness of the users and precision of the retrieved results.

the results of testing hypotheses showed that user’s philosophic mindedness, increases the precision of the retrieved results from scientific databases

With the development of the web, image search is considered to be one of the most important approaches and one of the major challenges for users. On the other hand, relevance as a cognitive concept has always been of interest and dates back to the time when one tried to retrieve and make good use of information. The inadequacy of the algorithmic approach proved that it is only the user himself who can judge the relevance of the document to its need and use. As a result, mental attitude has replaced military relevance in relevance studies. The purpose of this study is to investigate the viewpoints of graduate students of Ferdowsi University of Mashhad on subjective and objective criteria of relevance judgment in image retrieval from Google search engine in order to provide solutions to improve the retrieval approach in image retrieval systems.

This is an applied research using survey method. The statistical population of this study is graduate students of Ferdowsi University. Thirty male and female of BA, MA and doctoral students from various faculties of Ferdowsi University of Mashhad formed the sample of this study. The research data were collected through a questionnaire consisting of four sections. The first and the second part of the questionnaire before the beginning of the search session and the third and fourth part of the questionnaire after the end of the search session were given to the subjects. In this regard, subjective and objective criteria of judgment of the users in relation to the images were studied in order to determine with what criteria the users judge the relevance of the images and make their choice.

The findings showed that, in both subjective and objective judgment stages, except for "subject" criteria, "updating", "image attraction", "accessibility" and "information quality" criteria were important. The most relevant criteria for judging students regarding the relevance of images retrieved in Google's search engine were identified. In addition to the stated criteria, it was observed that the users focused on the "information effect" with emphasis on criteria such as "interesting" and "enjoyable" and the average score above these criteria indicates their importance. The findings also indicated that users place less importance on the creator(s) of the image as a specific criterion in the web environment, and these criteria are not among their top priorities in information selection. In general, it can be said that the judgment of the user on the basis of their needs, feelings and situation is very important. It is recommended that further research be carried out in order to obtain new findings in order to assist in the design of more efficient and more appropriate image search engines that are consistent with user behavior and characteristics.

What distinguishes the present study from other studies is the image search approach that has been studied with emphasis on Iranian users, Google search engine, and in two stages of subjective judgment and objective judgment that differs from the other researches.

Pubmed is among the most renowned medical databases. It uses MESH as a controlled vocabulary tool for facilitating the search process. Recently it has applied a second suggesting system (keywords and phrases) in this regard. Since information systems aim at retrieving the most relevant results، analyzing the efficiency of this new suggestion system and the old MESH terms from users'' point of view would be of importance in this regard.

As an applied study، this survey has been conducted through distributing a questionnaire during search sessions of users. To this end، a sample of 40 specialists، in the field of medical sciences، was selected through a purposive sampling method and the results were analyzed using SPSS 16. 0.

the results show that there is no significant difference between documents relevance when Pubmed suggestions or MESH terms are used during each search session. According to the findings of this study both Pubmed suggestions and MESH terms help the user with better understanding the concept and they both broaden the terminology of users. At the same time both methods are efficient in relevancy of the retrieved documents.
