Abstract—Topic maps are a Semantic Web technology for
semantic annotation of resources to enhance the quality of
search output. The main idea of this research is to present a
query expansion method using topic maps-based ontology for
query expansion process, furthermore this paper proposed a
novel automatic approach to construct topic maps from
Wikipedia XML corpus. Wikipedia is general purpose, freely
available online, is containing up to date information so it is a
suitable option for topic map development. The proposed model
is implemented and then applied on a test collection. The results
show that using topic map-based ontology in query expansion
process improves search accuracy in keyword-based
information retrieval.
Index Terms—Ontology, information retrieval, semantic
web, topic maps, query expansion.
