Currently, due to the development of Ubiquitous and IOT techniques, research on
the context awareness techniques that offer useful information has been conducted.
Also, the context awareness recommender service which recognizes the current
user’s location and offers appropriate information has been researched. Therefore,
most users prefer searching for the personalized information using more
convenient and dynamic mobile information retrieval services than using existing
desktop PC services in the limited space. Therefore in this paper, we implemented
semantic mobile information retrieval service using ontology.
