Ontology-Aided vs. Keyword-Based Web Searches: A Comparative User Study
MetadataShow full item record
Ontologies are formal explicit description of concepts in a domain of discourse, properties of these concepts, and restrictions on these properties that are specified by semantics that follow the “rules” of the domain of knowledge. As such, ontologies would be extremely useful as knowledge bases for an application attempting to add context to a particular Web search term. This paper describes such an application and reports the results of a user study designed to compare the effectiveness of the results of web search queries formulated using an ontology -aided application with those obtained using only a keyword-based search engine. The results of the study demonstrate that an ontology -aided search application does indeed increase the effectiveness of web searches for those searches requiring a deep domain knowledge.
