TLDR
The meaning of context in relation to ontology based query expansion is examined and a review of query expansion approaches including relevance feedback, corpus dependent knowledge models and corpus independent knowledge models are included.Abstract:
This paper examines the meaning of context in relation to ontology based query expansion and contains a review of query expansion approaches. The various query expansion approaches include relevance feedback, corpus dependent knowledge models and corpus independent knowledge models. Case studies detailing query expansion using domain-specific and domain-independent ontologies are also included. The penultimate section attempts to synthesise the information obtained from the review and provide success factors in using an ontology for query expansion. Finally the area of further research in applying context from an ontology to query expansion within a newswire domain is described.read more

A knowledge-based search engine powered by wikipedia
TL;DR: Koru is a new search interface that offers effective domain-independent knowledge-based information retrieval that exhibits an understanding of the topics of both queries and documents, and is capable of lending assistance to almost every query issued to it.
Ontologies and the Semantic Web
TL;DR: This special issue of IC focuses on the use of the Web by computer systems and agents and argues that by supporting the notion of “getting work done,” the Semantic Web will become more useful, valuable, and pragmatic.

A translation approach to portable ontology specifications
TL;DR: This paper describes a mechanism for defining ontologies that are portable over representation systems, basing Ontolingua itself on an ontology of domain-independent, representational idioms.

Indexing by Latent Semantic Analysis
TL;DR: A new method for automatic indexing and retrieval to take advantage of implicit higher-order structure in the association of terms with documents (“semantic structure”) in order to improve the detection of relevant documents on the basis of terms found in queries.
