Current online hotel booking systems have some problems helping travelers find hotels that meet their interests. In order to overcome these problems we have defined hotel-domain ontology to include three concepts: (1) those associated with hotels themselves and their relationships with neighboring artifacts; (2) those representing components of a hotel to be evaluated and their properties; and (3) those corresponding to subjective, ambiguous terms that are used when searching or evaluating hotels. A Semantic Hotel Search System (SHSS) using currently available semantic Web technologies was developed that enables travelers to find hotels using the system.
