Goal: Considering the positive effects of scientific productions of scientific-citation databases on scientometric indicators of the works indexed on those databases, this research investigates the effects of altmetric scores provided by the Mendeley Scientific-Citation Network on the scientometric indicators of Scopus and Google Scholar. Methods: The present research is a basic study with a quantitative approach that uses the citation method to investigate the effects of altmetric scores of the scientific productions of the semantic web domain derived from the Mendeley and altmetrics databases on the indicator of the number of citations received for these works on Scopus. The thematic domain of the present research involves scientific productions of Iranian authors in the semantic web domain, indexed from 1960 to 2021 on the Scopus database. The statistical population of this research consisted of 271 records at the time data were extracted from the Scopus database (10/02/2022). For the statistical analysis, correlation coefficient and stepwise multiple regression tests were used in addition to descriptive and inferential statistics. Software used included Excel and SPSS. This research first searched scientific productions of the semantic web domain on Scopus. Then, to meet the main goal of the research, i.e., evaluating the scientific productions of Iranian authors in the semantic web domain and investigating the effects of the activities of these authors on the Mendeley and Altmetric databases on the indicator of the numbers of citations received on the Scopus, the search process was limited to Iranian-affiliated scientific production on Scopus. In the next stage, altmetric scores related to these scientific productions were retrieved from the Mendeley and Altmetrics databases and then prepared for statistical tests. The retrieved works were case studied to increase the accuracy of relating the themes of the works under study. Findings: A survey of scientific productions of semantic web domain on Scopus revealed that the highest number of the works in this domain was registered in 2010, with the first indexed

Purpose: One of the hottest topics in recent years in the Artificial Intelligence community, as well as in the web community, is the Semantic Web. It has gained the attention of many researches in e-learning field. Thus, the purpose of paper is to review the architecture of the Semantic Web, to review key concepts in e-learning and to categorize and examine the application of the most important concepts of semantic Web (such as Intelligent Agents, Resource Description Framework (RDF), Concept Map, Ontologies, and Linked Data) in a variety of e-learning systems (including web-based courses, learning content management systems (LCMS) and Adaptive and intelligent web-based educational systems).Methodology: This is an analytical review (systematic) and the library research methods have been used to collect and analyze the information.Findings: After categorizing and examining different concepts of the semantic web and their application in e - learning systems, it was observed some studies have been conducted to create a repository of meaningful and reusable learning resources, The meaningful design of the whole components of the educational system, to assess students' skills and guide them, to propose adaptive course materials based on the learning behavior of students, knowledge construction and representation in a meaningful way, to find the right resources at a faster pace, to build collaborative and interoperability learning content management systems (LCMS) and improve queries in them. Conclusion: According to the studies, integration of e-learning and semantic web improve the quality of learning and enhance the performance of learning systems.

Aim: The aim of this study is to introduce the methods of transferring relational databases to ontology, classification of entering resources for transferring methods and identify the most important methods which exist in each group. Method: In this study, bibliographic analysis was used to gather and examine papers published on transferring relational databases to ontology. Some papers are derived from paper databases and others from papers published on the Internet. Results: After identifying the existing methods for transferring relational databases to ontology, they were classified into three groups: relational schema, conceptual data models and HTML pages of which the easiest accessible source is HTML pages which does not need cooperation of owner of the relational databases. However, since they can't be considered as real relational databases the hidden concepts in relational databases can't be derived from this source. In terms of data access, it should be noted that retrieval of all records in a relational database through the web-site is impossible. Creating conceptual model is always the first step in the process of creating database, so this model may not express the latest changes and corrections made in the database. The changes in implementation level are not usually reflected in the conceptual model. The conceptual model may not be accessible after designing and creating database. Also, some conceptual model tools do not support all features of conceptual models. Therefore, the relational schema seems to be the best source to create ontology from relational databases, when the database structure and data be accessible and owner of database is cooperative.
