چکیده

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 paper, 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 combination of applying different ontology has a great influence on the retrieval effectiveness for different query domains.

Fuzzy ontology for medical information retrieval

Ontology-based information retrieval is a key component of the Semantic Web. However current “crisp” ontologoies suffer from issues related to disambiguation of text terms and lack of domain knowledge necessary for effective query refinement. The fuzzy ontology approach is designed to allow personalised and group ontologies to be shared and collaboratively developed within the framework of exis...
