AJAX widget for semantic query expansion

Research output: Contribution to journalConference articleScientificpeer-review


We introduce the idea of utilizing ontologies as a service for query expansion, based on an AJAX widget. This ONKI Query Expansion Widget can be integrated into the search input field of a traditional keyword-based legacy system by one line of JavaScript code, making the search system semantic. For example, when searching for "tools", also "hammers", "axes" etc. can be found based on the underlying hyponymy. In the same vein, the spatial relations of a geo-ontology or temporal relations can be utilized. Application of the widget in legacy search systems on the web is discussed by examples. The widget makes it possible to utilize the ontologies of the Finnish Ontology Library Service ONKI in a very cost-efficient way.
