Sachio Hirokawa, Tetsuya Nakatoh, Hiroto Nakae, Takahiko Suzuki, Tourism Informatics -Towards Novel Knowledge Based Approaches-, Springer Berlin Heidelberg, Chapter: Discovery of Implicit Feature Words of Place Name, Volume 90 of the series Intelligent Systems Reference Library pp 31-42, 2015.07, Individual opinions and experiences are published in Web as CGM (consumer generated media). A tourism blog which a tourist wrote his experience and impression in a certain area is very helpful information for other tourists. However, a user cannot obtain such precious information without knowing the relation of blog articles and concrete place-names. We paid our attention to the hierarchical structure of place-names. In this paper, we propose the method of connecting related words to the place-name which does not appear explicitly in a blog article paying attention to the hierarchical structure of place-names. From 45,553 blog articles about the Karatsu area in Saga Prefecture, the potential related words about 78 place-names of Saga Prefecture which have not appeared in the blogs were extracted. 4 subjects evaluated that meaningful related words are obtained in 80 % or more of the place-names. However, the direct relationships between the place-name and related words was not able to be guessed easily..

Volume 90 of the series Intelligent Systems Reference Library pp 43-58, 2015.07, Some tourists will write their activities to blogs. Such individual experiences are interesting compared with the official information by tourist agents. Therefore, extracting tourist’s activities from blogs are meaningful. We have attempted to extract tourism objects from tourists’ behavior statistically. In this paper, the objects of the behavior were extracted using dependency analysis, and tourism objects were specified by evaluation with regionality..

In recent years, databases of academic papers have been developed, and researchers can search for related research using keywords and so on. However, it is a very time-consuming task to discover appropriate papers exhaustively from a large number of academic papers, classify them, and understand their contents. We have been researching methods that can properly extract papers of related research from an academic paper database. After finding those papers, researchers need to understand the relationship between those papers.We believe that there are several types of relations between papers that appear in citation expressions of related papers. In this paper, automatic classification of citation expressions is performed as the first step in the analysis of citation expressions, and the analysis results of each cluster are reported..
