The aim of this research is to conduct an analysis of qualitative and quantitative studies on applying thesauri to the construction and development of ontologies and the identification of subject domains. We will investigate the approaches and methods used in these studies.

This descriptive-analytical research was conducted following the seven stages of systematic review suggested by Petticrew and Roberts (2008). Data analysis and visualization were facilitated using the DatawRapper software.

The analysis of studies in the area of applying thesauri in the construction and development of ontologies, while identifying and presenting the subject trends of studies, frequency, methods, languages and approaches, showed that the studies in this area include six main topics as follows: applying thesauri in the construction and development of ontologies in connection with multilingual information retrieval, applying thesauri in the construction and development of ontologies to cover a specific subject domain, applying the ISO 25964 standard in the development of ontologies using thesauri, presenting the framework, methods and tools for the use of thesauri in construction and development of ontologies, improving semantic relations and concept mapping using thesauri in the construction and development of ontologies and review studies of thesauri conversion to ontologies. 

Various subject domains, across different time periods, have benefited from applying thesauri for the construction and development of ontologies. Thesauri, as semantic tools, have provided the context for organizing, retrieving and accessing information more accurately and easily for stakeholders and applicants across various domains. Despite these advancements, the lack of a standardized and consensual framework, coupled with the need to update methods, approaches, and tools due to the reliance on natural language processing (NLP) technologies and knowledge engineering, has necessitated further research to mature this field.

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.

Currently، the main portion of knowledge is stored in electronic texts and documents and for transferring that knowledge effectively، we must use proper methods to gather and retrieve relevant information. Ontologies provide means to produce structured documents and use intelligent search instead of keyword search. Ontology defines the common words and concepts used to describe and represent an area of knowledge. However، developing ontologies is a time consuming and labor work، so many ontology developers try to facilitate and speed up this process by reusing other resources. In fact، thesaurus contains semantic information and hierarchical structure that make it an appropriate resource for ontology construction. Therefore، we determined to use the thesauri previously developed at Iranian Research Institute for Information Science and Technology (IRANDOC) to construct ontology in basic sciences domain. At first، we synchronized common concepts in thesauri before integrating them as a macro thesaurus and removed inconsistencies. To reduce the amount of time and human resources which were needed for synchronizing process، Thesaurus Synchronizer was developed to illustrate differences between matched cases of two thesauri. It provides powerful tools for demonstrating differences and suggestions for each of the existing matters. Thus، domain experts synchronized each two thesaurus semi-automatically. Then we merged thesauri and transform the data format into ISO 25964 standard. The conceptual model have been designed based on the terms and their relationships in the integrated thesaurus and the concept maps that were designed by domain experts for each of basic sciences (Chemistry، Physics، Biology، Geology and Mathematics). We used the methodology called METHONTOLOGY in this stage. The main activity in this methodology is conceptualization and it enables the construction of ontologies at the knowledge level. Ultimately، the ontology was generated by formalizing and implementing the conceptual model in OWL، a web ontology language which is recommended by the World Wide Web Consortium. The next step is to refine the relationships to more specific semantic relations. Our domain experts tried to refine some relationships manually but we decide to design an appropriate method for refining the ontology semi-automatically. Also we need to add more details to our ontology and turn it into heavyweight ontology to get more advantages from it in formal reasoning. The main aim of this project is to create a standard ontology to be used in information storage and retrieval system.
