ONTOLOGY-BASED INFORMATION RETRIEVAL USING FUZZY CONCEPT DOCUMENTATION

Ontology is a conceptualization of a knowledge domain being shared by a group of users and represented as a machine-readable format. Embedding ontology into information retrieval is a natural way to improve the effectiveness of searching results. In this article, an ontology-based information retrieval framework is proposed to combine the documents retrieval technique with ontology. The ontology used in the system includes a general semantic ontology, domain knowledge, and automatic generated fuzzy concept hierarchy. The experimental results show that a combination of applying different ontologies has a significant impact on the retrieval effectiveness for different query domains.
