Abstract
Designing tours requires much time and effort of designers because they have to consider so many kinds of things and quality of work excessively depends on their personal skills and experiences. One of the difficulties of designing tours is that designers have to consider fundamental needs of tourist, which are often kept unsaid. This paper proposes a data structural definition of tourism resources that can help designers grasp tourists' fundamental need from their requests and design tours more efficiently. By analyzing tour service, the information which is useful for proposing services considering tourists' requests is divided into three types; geographical information, time information, and meaning information. Based on those three types of information, this paper defines two indexes for proposing services matching customers' requests. One is "Similarity Score", which means how similar what the customer want to do and what a tour service let customers do are, based on meaning information. The other is "Duration Optimality", which means how long the customer can enjoy the service under the requested situation, based on geographical and time information, Data structure is defined so that design supporting system for sightseeing tours can propose tour services to designers based on these two scores.
