The purpose of the current research is to draw and analyze the intellectual structure and evolution of knowledge in the field of RDF with the method of co-occurrence analysis of words and clustering of concepts and events in this field.This is an applied research that was carried out with a scientometric approach.The statistical population of this research includes all the researches conducted in the field ofRDF in the Web of Science database from1998-2021Also,the data collection tool in this research is note-taking and the data analysis tool is co-occurrence analysis of words and network analysis using Vosviewer,Netdrow, Spss and Bibexecl software.The findings of the research showed that the keywords RDF, Semantic web, Ontoloty,linked data and SPARQL are the most frequent words and the keywords RDF*semantic web,RDF*Academic Ontology and RDF*SPARQL are the most frequent word pairs. Also, the co-occurrence analysis of words network includes six clusters named data model scalability.RDF representation of bibliographic entities and relations.ontology alignment.semantic web and linked data.data management and publishing and data mining.The clusters of data model scalability.ontology alignment.data management and publishing and data mining have not yet reached sufficient maturity and require a lot of follow-up and research in these fields.The results showed that the scientific productions of the RDF field, despite its upward publication trend, have more subject dispersion and are more oriented towards the semantic web, and the analysis of the co-occurrence network of words in this field also has a greater subject dispersion,which indicates the interest of researchers to various topics in this area

Purpose: The purpose of the present study is to investigate the compliance of the research information system of Shahid Chamran University of Ahvaz with the technical and information criteria of the web environment.Research method: descriptive-applied and combined with quantitative and qualitative methods. In the systematic review section, the theme analysis method was used to extract the technical and information criteria of the web environment, and in this regard, the basic, organizing and comprehensive themes were extracted. In a quantitative part, descriptive statistics tests (frequency and percentage) have been used to check the compliance of Shahid Chamran University of Ahvaz research information system with the technical and information criteria of the web environment.Findings: results of the research in the field of compliance of the research information system of Shahid Chamran University with technical criteria showed 46 basic themes and 7 organizing themes and in field of information criteria, a research system including 51 basic themes and 7 organizing themes. Also, according to the examination and compliance of the research information system of Shahid Chamran University with technical standards in web environment, it has been determined that the contents in system are not properly organized and the support for different parts of system is not provided, and besides that, system guide in There are no different sections.Result: The research information system of Shahid Chamran University of Ahvaz is 47.05% compatible with the information criteria of the web environment and needs a serious revision in its technical and informational structure.

The purpose of this study was to Survey of the success key factors application in the implementation of knowledge management in Water and Power Organization of Khuzestan.This research is applied in terms of purpose and a quantitative by using a descriptive survey method. The data collection tool is a questionnaire whose reliability was calculated by Cronbach's alpha test of 0.87. In the present study, one-sample test, Kolmogorov-Smirnov test has been used. The data of this study were analyzed using SPSS software version 26. The results indicate that the mean of organizational structure (2.89) in knowledge management implemented in the Khuzestan Water and Power Organization is lower than average. Regarding the status of organizational culture (3.20) in knowledge management implemented in Khuzestan Water and power Organization, the results showed that the mean acquisition is higher than average. The results show that the mean status of information technology (3.23) in knowledge management implemented in Khuzestan Water and power Organization is higher than average While the results indicate that the mean status of human resources (2.75) in knowledge management implemented in the Khuzestan Water and power Organization is lower than average. Finally, the results indicate that the leadership status (3.75) in the knowledge management implemented in the Khuzestan Water and power Organization is higher than average. Among the success key factors for the implemented knowledge management; The organizational structure and human resources are not at the desired level and it is necessary to provide the ground for improving the status of these factors by planning in this regard.
