Developing a semantic network of concepts in primary school textbooks based on folksonomy

The purpose of the present study was to create a semantic network of concepts in the field of education with the help of folksonomy. The research was applied in terms of purpose and in terms of method it was a co-lexical analysis. This analysis means creating a word-concept in the design of the thesaurus and its conversion to the ontology. This means that first, the texts, the proposed links, as well as the terms and words inserted by the users were turned into the words - concepts. Then, at the same time with this process; 10 experts in the field were interviewed, based on the purposive sampling. Six Primary school Fārsi text books were the main part and the demands of this study from the research population, participating in the folksonomy. The related users were 240 experts of the Organization for Educational Research and Planning and among them 148 people were selected as the sample, based on the Morgan table. The results of this project were run in Fārsi parser and Rover matrices software for the lexical analysis and then they were inserted in the Protégé version5.5 and they were represented with OWLViz and OntoGraf plugins. The desired relationship was categorized into seven general categories, as well as 24 subcategories, and 122 (sample). The hierarchy and relationships among them were determined by extracting the concepts, and the semantic knowledge and repetitive words used by the users and the experts in the folksonomy were identified. Using this method is effective in systematizing the primary school textbooks, so that students and teachers could access the resources in the web environment. Also, it facilitates the storage and retrieval of information.
