Constructing the ontology of Children and Young adults based on the ASKA Thesaurus

The purpose of this study is to explain the methodology and relationships between concepts for designing and creating ontology of children and Young adults as one of the basic technologies for the realization of the Semantic Web.

The present study is one of the applied researches because it deals with the creation of ontology of children and Young adults which is one of the essential tools in designing information systems in the field of children and Young adults. Also, in terms of purpose and method of data collection, this research is considered as a descriptive and survey research. Conceptual design of ontology was done using Methontology methodology based on the concepts and relationships in ASKA thesaurus (Thesaurus of Kanoon-e Parvaresh-e Fekri Koodakan va Nojavanan). The face and content validity of the conceptual structure was confirmed by experts in the field of Children and Young adults of the National Library and Delphi method. The tool used to build the Protégé of the software is version 5.5.0

The results showed that the ontology of Children and Young adults can be composed of 12 main classes (education, literature, communication, history, social sciences, Information science & Computer, religion, psychology, linguistics, science and technology, philosophy, Arts and recreation). 4 types of interpretive attributes (1- Definition, 2- Synonyms 3- Equivalent to, 4- Notes) are used. This ontology includes 42 types of object attributes (1-Instrument for, 2- Executed by, 3- Executes, 4- Evaluates, 5- Is Used of, 6- Uses, 7- Has kind, 8- Is part of, 9- Based on, 10- Checked in, 11- Taken from, 12- Held in, 13- Founder, 14- Has negative influence, 15- Supporter, 16- Is a related field of, 17- Has skill, 18- Is Method of, 19- Is a time for, 20- Is a measure of, 21- Includes, 22- Has symptom, 23- Provider, 24- Accessible by, 25- Is low of, 26- Prevents from, 27- Is affected by, 28- Opposite to, 29- Execution place, 30- Operation place, 31- Phase of, 32- Studies, 33- Is concept of, 34- Beneficial for, 35- Is effective on, 36- Caused by, 37- Is sign of, 38- Is theory of, 39- Is a kind of, 40- Is a, 41-Collaboration with, 42- Has Property), Which of these properties, a symmetric properties and four Transitive properties and 6 of these relationships are Inverse properties property and also has 16 types of data properties (1- Uses, 2- Abbreviated, 3- Created by, 4- Used for, 5- Date of creation, 6- Date of holding, 7- Date of establishment, 8- Date of birth, 9- Date of death, 10-Has Kind, 11- Are treated, 12- Including services, 13- Symptoms, 14- Causes, 15- Accessible from the source, 16- Another name) and 214 samples are listed.

Given the focus of new standards in the field of knowledge organization on ontological approaches, the need to understand and recognize ontologies, relationships, and how they operate and function is very important. In this regard, the ontology of Children and Young adults can be one of the useful and effective tool for this purpose and a representation of knowledge in this field. This essential tool can be used in the design of information systems for Children and Young adults, and also as a basis for the development of future terms and concepts in this field.
