SEMANTIC SEARCH APPARATUS AND METHOD USING MOBILE TERMINAL

摘要

Disclosed are an apparatus and a method of searching for information by a mobile device. The present invention provides simplified ontology to be applicable to a mobile environment having a limited resource, and provides ontology capable of providing a combined search environment by combining DBs used by various applications within a mobile device, respectively. Further, the present invention provides a semantic search engine providing a function of searching a local database within a mobile device, and expanding a search to a web as necessary and performing the search.
