Creating a Persian Ontology through Thesaurus Reengineering for Organizing the Digital Library of the National Library of Iran

Abstract

One of the most important features in a digital library is the information retrieval system. Giving semantic search capability to such system is the goal of research in current decade. Semantic search requires establishing knowledge enabled by intelligent inferences based on an ontology. There is currently no ontology for the Persian language. Since the creation of an ontology from scratch is time consuming it was decided to reengineer a current thesaurus in the Persian language named ASFA to create the ontology using an automatic ontology learning methods. This methodology is proposed in this paper. This ontology will be used to organize contents in digital library of the National Library of Iran.
