The main aim of Information storage and retrieval systems is keeping and retrieving the related information means providing the related documents with users’ needs or requests. This study aimed to answer this question that how much are the system relevance and User- Oriented relevance are matched in SID, SCI and Google Scholar databases.
In this study 15 keywords of the most repeated ones that were related to “Human Information Interaction” and its subheadings were selected and searched both in Persian and in English in the mentioned databases for two one week periods. The results were arranged according to the system relevance based on the retrieval and displaying order. From each search the first 10 results were selected and sent to the subject experts and asked them to rank from 1 to 10. Data were descriptively and analytically (using Spearman correlation test) analyzed by SPSS software.
Subject experts’ relevance score in Persian was lower in ISC than SID and higher than Google Scholar. The most subject relevant records were in the third score of system relevance. The records with the lowest system relevance score also had the lowest subject experts’ relevance score. SID in Persian had a strong and positive relation between the both scores but there was no relation in ISC. The highest matching level of the both scores was seen in SID in both languages on the both periods which means more likely to retrieve relevant records.
There is a similar retrieval pattern in both languages with subject expert’s view in SID showing the highest precision which was the lowest in Google scholar in Persian

The need for cognition to the extent of involvement of the individual in intellectual activities, to assess individual differences in motivation for information processing, individual differences in the tendency of people to engage in and enjoy effortful thinking and, finally, refers to the processing of sound messages. The purpose of this study was to investigate the effect of need for cognition on student's collaborative information behavior.
This study is applied research .Among 340 students graduate from the Faculty of Psychology and Educational Sciences in Allameh Tabatabai University, 181 students were selected randomly and measures need to recognize the information behavior participatory out the questionnaires.
The research findings indicate the need to recognize significant differences by gender and field of study participants were women. Students seeking a partnership relationship between need for cognition and behavior were observed. Information seeking behavior in terms of the need to know their students significant difference was found and thus the need to know the information seeking behavior of effective student participation.
the need for cognition is effective on Students’ collaborative information behavior (CIB).

this study aimed to explore the impact of objective complexity and Product of work task on user's interactive information searching behavior.
The research population consisted of MSc students of Ferdowsi university of Mashhad enrolled in 2012-13 academic year. In 3 stages of sampling (random stratified, quota, and voluntary sampling), 30 cases were selected. Each of these cases searched 6 different types of simulated work tasks. Students’ Interactive Information searching behavior was measured by “loud thinking reports” and “log files”. Also, reliable questionnaire (Cronbach's alpha= 0.88) was applied to measure subjective complexity. Validity of tools was verified through Faculties of KIS at Ferdowsi university of Mashhad.
By increasing level of objective complexity, users view more databases, search engines and web OPACs. Also they use more queries and select resources, visit and analyze more results and spend more time during search process. Totally, they feel less satisfaction and success. It was also found that most participants spend more time to search IR systems related to tasks including intellectual product. Also, they iterate queries, use more search facilities, view, analyze and select more search results and resources. At the end, in spite of more interaction, satisfaction and perception of search success were reported not favorable.
It is necessary to pay attention to work task characteristics in designing interactive and personalized IR systems. So, recommendations raised from this study are appropriate to improve and develop Interactive IR systems.

The aim of this study is to assess the Iranian Personal electronic information management of knowledge and information science and medical Library and Information Sciences faculty members based on the Jones model.
This study is kind of application research and in terms of data collection is descriptive and analytical study. The statistical population included faculty of knowledge and information science and medical library and information science in Iranian state universities. Data were collected by a questionnaire that its validity is confirmed by the ISprofessors, and its reliability was measured by Cronbach's alpha coefficient (0.81). To analyse the data, descriptive and inferential statistic using SPSS statistical software was used.
Analysis of the data showed that the average of activities in finding and re-finding were 4.0101, in storage was 4.0783, in organization was 3.2424, in maintaining were 2.8106, in security were 3.1162, in measuring and evaluation was 3.7803, in making sense of things was 3.9192 and total average personal electronic information management was 3.5659. Findings showed that there was nosignificant difference in the personal electronic information management in terms of gender and organizational affiliation, but in terms of the scientific and age there, there were significant differences among faculty members. The differences were found between the scientific degrees of associate professor and professor, and between the age group 36-45 years old and up to 56 years old.
The results indicated that faculty members in the age group 46-55 years old as well as associate degree had the best performance. Also, faculty members of medical library and information science had been used greater extent personal information management activities and personal information management quality women had better than men. Faculty members had desirable operation to Retrieve and store information, but they do not well maintained this information and do not provide appropriate security measures. In general, management of personal electronic information was in the relatively good level.

Considering the increasing number of users who interact with online social networks, it can be inferred that these networks have become an essential part of user's lives and play different roles in their everyday life. Therefore, the present study aims to explore the role of these networks in user's everyday-life information seeking.
This research is an applied research with qualitative approach and it was conducted using thematic analysis method. This method includes a semi - structured interview with active users of online social networks.
Results indicate that online social networks play different roles in the user's lives, such as entertainment, education, communication and interactions; accompanied by, news, favorite contents, and up-to-date information; but, these networks face some challenges that affect information seeking behavior of users which compels users to utilize active information seeking.
Richer social capital and diversity of users in an individual's social network leads to the access to more qualitative information which in turn increases the probability of finding the required information and achieving the expected results with the least effort.

University students due to having better media literacy are among the groups that use social networks more. Aim of this research was to study the use of social networks by university students based on demographic and educational variables.
This quantitative applied research utilized survey design. Data collection instrument was a questionnaire developed by the investigator. Validity of questionnaire was evaluated by expert colleagues and samples of respondents. Reliability of tool was tested by Spilt Half reliability. Population of the study was 4524 undergraduate students of Azarbaijan Shahid Madani University. The sample size was 393 students. Descriptive statistics (percent, frequency and mean) and inferential nonparametric statistics (Spearman,Mann-Whitney and Kruskal Wallis) was used in order to analysis data. SPSS17 was used to analysis the data and Excel was used to draw the charts.
Majority of the students used social networks. Viber and Line was the most preferred social networks. Daily average use of social networks was 140 minutes. The most important reason of using social networks was fun. Friends of respondents in social networks were mostly the face to face visited individuals. Hand-phone was the important medium used in social networks. According to the majority of students validity of information in social networks was not valid. There was significant correlation between proportion of social network use and Grade Point Average (GPA), number of friends in social networks and features of information in social networks. There was significant difference in use of social networks between students of four studied domains.
Usage of social networks is usual among university students. Students almost used social networks as a medium for fun and communication. The students with higher GPA used social networks fewer.

In order to comprehension of interactive content and content production standards, and also users interaction with LMSs, and their behavior in dealing with information, the aim of this paper is to examine the users interaction information provided in the eFront application, an open source Learning Management System, by emphasizing SCORM standard.
The method that used in this study, is Netnograghy which is a qualitative method and it is ethnography in online society. All the data is collected online by using the software reports.
by comparing users’ behavior between two courses in eFront application we understand that in courses which the content is provided by text and images need to have an online teacher and that content is not enough. The users who was attended in course “Installing virtual reference desk" not only need information in text format and images but also need to interact with teacher directly. In the first three chapters of this course which have made in film format, users had fewer problems. The users who have attended in course with web conference passed the course more successful than before. In the course "EndNote” which content have made in film format, users could make good communication with information and had less problem.
Provide educational content in the context of "interactive learning management system" should be the terms and conditions. You can not just put the text and image content to reach the desired result. Although content in the form of educational films can provide more help to the user, to achieve better results, we need to fully interactive content which is available to users, in order to control their activity in learning environment.
