Abstract: Recently, the number of tourists getting tourism information using websites has
increased. At the same time, tourism information on the World Wide Web (WWW) has been
rising significantly. This large amount of information causes confusion and trouble for
tourists. In order to get clear and effective tourism information, this study proposed a
method to search websites regarding to categories. Categories such as restaurants or
accommodation can contribute to acquire appropriate and satisfactory information. In order
to search Websites regarding to categories, it is necessary to collect Websites from the WWW
and classify them into categories. This research focuses on classification of Websites into
categories. Previous researches deal with the tf-idf method and the Bayesian Classifier,
website classification methods using text information. This research proposed a website
classification method which concentrates on websites belonging to a given category and on
characteristic keywords those appear only in the given category. The effectiveness of this
approach was examined by using data from the directory-based search engine “Yahoo!
Japan” and from the WWW randomly. The experimental results show that the proposed
method can classify Websites into proper categories with a high classification degree
compared to a previous method.
