Ontology, as a semantic tool aims to provide a definitive and comprehensive classification of entities across all domains of existence and to retrieve knowledge from resources. Ontologies have significant applications in the fields of medicine and the understanding and treatment of diseases. Therefore, the aim of the present research is to design an ontology for the domain of Multiple Sclerosis (MS) and the stages of its construction. This study was conducted with a qualitative approach using content analysis based on the Bermejo OASys method. The stages considered for constructing the MS ontology include nine steps as follows: 1) determining the domain, scope, or purpose of the ontology, 2) identifying information resources including books, articles, experts, and others, 3) identifying and collecting terms and concepts from texts, 4) determining the subject coverage, scope, and main classes of the ontology, 5) establishing the hierarchy of terms and concepts, 6) defining and determining the relationships between terms and concepts, 7) describing the characteristics of categories and the relationships between them, 8) determining relationships between samples and classes, and 9) creating necessary constraints and rules. The statistical population of the research consisted of specialized Persian and English information resources in the field of MS. To this end, all symptoms of this disease, treatment methods, and its diagnosis were extracted from books, articles, and specialized glossaries in this field. The conceptual framework of the MS ontology was developed based on relevant specialized texts and manually using Protégé software version 5.5. The MS ontology includes six main classes as follows: 1) types of MS, 2) treatment methods, 3) diagnostic methods, 4) symptoms of the disease, 5) factors contributing to human susceptibility to this disease, and 6) its complications, each of which also includes its related subclasses. Additionally, to determine the relationships between concepts, ten main semantic relationships were identified, including: 1) has a cause, 2) is a This study focuses on the role of perceived benefits and risks, along with their dimensions, in influencing users’ intentions to seek and share health information through social networks. The research employed a correlation-based applied survey method. The statistical population for this study included all students at the University of Tehran, with a determined sample size of 382. A total of 364 questionnaires were returned and analyzed using SPSS and LISREL. The results of the Structural Equation Modeling analysis indicated that nine hypotheses were confirmed while four were rejected. Overall, the findings revealed that perceived usefulness, credibility, and emotional support related positively to perceived benefits. However, no relationship was found between informational support and perceived benefits. Additionally, privacy concerns, time commitment, and psychological risk were positively associated with perceived risk. Conversely, no relationship were observed between mental intangibility or social risk and perceived risk. Furthermore, perceived benefits were positively related to the intention to seek and share health information, while perceived risk was negatively related only to the intention to seek health information.

Theoretical foundations and philosophical basis of library classification systems have always been important for information science professionals. This research studies the philosophical foundations and logical basis of the classification systems and structure of human knowledge and studies the logical basis of library classifications Scheme. Challenges and problems of traditional ideas about knowledge organization and its hierarchical structure have been studied and rhizomatic thought has been proposed as an alternative model for the tree and hierarchical structure especially for the organization of digital and hypertext information on the web. In Western thought, the tree structure based on Aristotelian logic has been the dominant model of classification and due to its problems, the rhizomatic structure is suggested. Information structure in digital space such as rhizomes moves in many directions and creates a multiplicity of connections and relations. The growth and emergence of interdisciplinary studies can be seen as evidence. Traditional, tree-based and hierarchical discourse of information organization isn’t enabled to understand the nature and characteristics of the digital information space and so to organize it. Necessarily to a paradigm shift, rhizomatic thinking can be a good alternative to traditional information organizing thinking.

The purpose of this study was to analyze the quantitative and critical content of research conducted by Iranian researchers in digital libraries in terms of research method, research community, topics, authors and their organizational affiliation and results of previous researches. The research method is quantitative content analysis. According to the mentioned purpose, the authors’ information, titles, abstracts, keywords of articles and dissertations related to this field of researches were analyzed. The statistical population of the study consists of 208 Iranian research outputs (137 articles and 71 theses) in the field of digital libraries that were selected based on their internal validity criteria. And to extract the data needed for the research, the research was conducted with the aim of analyzing quantitative and critical content in the field of digital libraries. In terms of place of publication and research, in research articles, Iranian Journal of Information Processing & Management (12) frequency; in Extension Articles, Journal of Monthly Books (12) frequency; and in the theses, Islamic Azad University of Tehran - North Branch (12) frequency، gained the most statistics. In terms of topics used, the results showed that topics such as “evaluation of digital libraries”, “concepts of digital, virtual and electronic libraries”, “feasibility of creating digital libraries” and “digital libraries user interface” gained the most attention. The results of content analysis indicate that the issue of digital libraries in previous researches of recent years has been growing in recent years and new topics such as semantic web, mapping, semantic integration and organization in this area have attracted the attention of researchers. The research has also shown that first, the bulk of the research sought to introduce and promote the conceptual and exemplary nature of the digital library, the knowledge that is largely available in English. Second, much of the research is repetitive. Third, no research has been done on the development of the digital library in terms of concept or technology. In addition, the results of some previous methodological research show that the most prominent examples are research methods that are quite feasible. Overall, the study of the topics studied and their timing in the field of theory and practice of digital libraries in Iran led to the identification of research gaps in this field. Researchers are therefore encouraged to look at other aspects of digital libraries that have not been studied or devoted to less research.

This research aims to study the presence contexts of infodemiology and the introduction and expansion of its framework. Based on Eysenbach’s View, infodemiology can be defined as the science of distribution and determinants of information in an electronic medium, specifically the Internet, or in a population, with the ultimate aim to inform public health and public policy. In this review article, library method has been used to define and describe the term “infodemiology” and its dimensions. In this study after an introduction investigating the present setting, and defining the concept of infodemiology, the framework of this science and its measurements has been studied and finally the relationship between infodemiology and public health has been described. According to the results, digital media technologies resulted in paradigm shift in choosing the ways in which people search their health information. The researches in this domain have been resulted in credible and significant measurements to track health information supply and demand. Also, infodemiological researches cause specialists design and develop health information databanks based on given measurements. The studies show that there is the possibility of applying some measurements as alarm systems for proliferating infection diseases or presence of new diseases. These measurements are called “infodemiology measurements” which reflect supply-based infodemiology and demand-based infodemiology. According to these, data collecting in this field and using its measurements could be useful in policy-making.

The present study investigated the analysis of search engines and meta search engines adoption process by University of Isfahan users during 2009-2010 based on the Rogers' diffusion of innovation theory. The main aim of the research was to study the rate of adoption and recognizing the potentials and effective tools in search engines and meta search engines adoption among University of Isfahan users. The research method was descriptive survey study. The cases of the study were all of the post graduate students of the University of Isfahan. 351 students were selected as the sample and categorized by a stratified random sampling method. Questionnaire was used for collecting data. The collected data was analyzed using SPSS 16 in both descriptive and analytic statistic. For descriptive statistic frequency, percentage and mean were used, while for analytic statistic t-test and Kruskal-Wallis non parametric test (H-test) were used. The finding of t-test and Kruscal-Wallis indicated that the mean of search engines and meta search engines adoption did not show statistical differences gender, level of education and the faculty. Special search engines adoption process was different in terms of gender but not in terms of the level of education and the faculty. Other results of the research indicated that among general search engines, Google had the most adoption rate. In addition, among the special search engines, Google Scholar and among the meta search engines Mamma had the most adopting rate. Findings also showed that friends played an important role on how students adopted general search engines while professors had important role on how students adopted special search engines and meta search engines. Moreover, results showed that the place where students got the most acquaintance with search engines and meta search engines was in the university. The finding showed that the curve of adoption rate was not normal and it was not also in S-shape. Morover, among simple and advanced pages of Google, a specific bias toward simple search pages could be seen in users. This part of the study confirmed Rogers' theory. Other results of the study indicated that renouncement of innovation was not only in decision phase. This part of the investigation was in conflict with Rogers' theory.
