Introduction: One of the semantic tools for retrieving knowledge from complex resources is ontology. With the advent of semantic web technologies, mapping and designing ontologies, as a tool for organizing and representing knowledge has become necessary. The purpose of this article was developing congenital heart disease ontology, and introducing its construction stages.Methods: The present study was conducted using content analysis method. The statistical population of the study consisted of all specialized Persian and English information resources in the field of congenital heart diseases in digital library of Isfahan University of Medical Sciences, Isfahan, Iran. The basis and the core of the methodology used to create congenital heart disease ontology was the methods introduced by Mohammadi-Ostani et al. and Bermejo methods. In total, nine steps are followed to build this ontology were as follows: 1. defining the scope and coverage of the subject, 2. identifying information sources (documents, books, and articles), 3. identifying terms and concepts, 4. identifying subject coverage and defining the domain and the main classes, 5. defining the hierarchy of terms and concepts, 6. defining the relationships between terms and concepts, 7. describing the characteristics of categories and the relationships between them, 8. defining the relationships among examples, and 9. establishing constraints, functions, and rules. In order to confirm the content validity, during the designing and editing of the ontology, the opinions of 7 pediatric cardiologists in Isfahan University of Medical Sciences were used at the third to sixth stages. The Protégé software was used to build ontology.Results: The congenital heart disease ontology included 6 main classes, 1. common congenital heart disease, 2. disease-related organs, 3. treatment methods, 4. diagnostic methods, 5. symptoms diseases, and 6. risk factor. Moreover, 8 main relationships were identified between concepts and terms as 1. diagnosed by, 2. feed, 3. treated by, 4. treated, 4. caused, 6. has complication, 7. is symptoms of, 8. is complication of have 2 sub-relationships is related with, has risk factor.Conclusion: This ontology can be a useful and efficient tool for organizing and retrieving knowledge in this field. The method of this research can also be applied to develop knowledge structure in other fields, too.

Introduction: One problem in conducting scientometric thematic analysis is selecting which of the bibliographic fields containing the topics can be analyzed. This study aimed to compare subject fields of documents to determine the field or a combination of fields which are suitable for conducting a complete and proper thematic analysis in scientometrics.Methods: This was a descriptive research with content analysis approach. Scientific products in the field of functional gastrointestinal disorders were extracted from the Scopus database. The analysis was done on 13798 documents, which included title, author keywords, and index keywords. After clustering using the K-Means method, and calculating the inclusion index for created clusters, the similarity of keywords between the three fields was determined.Results: There was a high similarity between the index and the author keywords (87.71 and 85.71). The low amount of the index in the title field and the index keywords (0) also suggested that there was little similarity between the controlled vocabulary and the keywords used by the authors in the title, and that authors did not use the preferred vocabulary in the title.Conclusion: Using the words of the title field will show the results of the natural language analysis. However, if the purpose of a study is categorizing terms, the use of index keywords field will be the most appropriate.

Introduction: This article aimed to study the main constituents of professional information seeking in organizational context of Emergency Medical Management (EMS) and Disaster Management Center in Bushehr City, Iran. In this study, we tried to investigate the relationship between job duties, professionalism, and information sources in organizational context.Methods: This study was done on the basis of a qualitative method called "interpretive field study". The method of data gathering was interview, observation, and the investigation of Emergency Medical Management documents. For data analysis, at first the concepts was extracted from the interviews and then, they were clustered. Finally, describing the relationship among the set of concepts, a model was presented for information Seeking of Bushehr emergency medical management technicians.Results: In this model, it became clear that the nature of job of emergency medical management technicians had divided their information seeking to two part: during the processes and after the processes. During the implementation of processes, information seeking was done in the decision-making time which was based on experience and collective consultation. After the implementation of the processes, to answer the information needs, the search for sources began. Method of discerning the information needs, searching for sources (experience, group consultation, official sources, …) during the implementation of process and after that, depended on job training, personal behaviors, and organizational norms which were present in study context.Conclusion: The emergency medical management authorities should consider the nature of profession and organizational context in information seeking behavior and should utilize from various information seeking pattern to meet the information requirements of emergency medical management technicians.

Introduction: This article intends to compare information literacy of International Branch students with Nursing students of Jundi Shapur University of Medical Sciences – Abadan Branch.Methods: This research is of survey-descriptive type which has been conducted using a questionnaire to collect the data. The population studied included 222 students studying at the international branch and nursing school of Jundi Shapur University of Medical Sciences -Abadan Branch.To analyze the data, SPSS13 was used. Descriptive analysis including frequency, prevalence, average and standard deviation as well as analytical statistics ANOVA, T-test and Tukey were implemented.Results: The findings showed that International Branch students enjoy a higher level of information literacy than nursing students. However, in general, the subjects enjoy an average level of information literacy and that there is no significant difference between the information literacy levels of freshmen and senior students. Other findings suggest that the subjects were at an average level in finding their required information resources in the library, as well as using computer and other accessories.Self-confidence in seeking information, assessment of retrieved information and self-satisfaction from the results of their searches and the ability to seek help from a librarian were all at an average level. However, the students stood at a low level as to finding their required information on the internet and using logical operators. The subjects used books more than any other information sources, and information networks stand as the first channel for seeking information.Conclusion: Since information literacy of the population was at an average level, planning for educational programs to promote information literacy of students is essential.Keywords: Information Literacy; Universities; Students; Information Resources.
