Exploratory Search System Based on Comic Content Information Using a Hierarchical Topic Classification

The purpose of our research is to provide in- formation access support based on the contents of a comic book. For this purpose, it is neces- sary to obtain information related to the story and the characters. In our previous research, we ex- tracted the information using a review sentence and built a comic search system based on the extraction results. This system determined the relationship between comics using the TF-IDF method. However, the TF-IDF method does not include the meaning of each word used in the re- view sentence. Therefore, this system may not be able to provide accurate comic relationships. In this study, we analyze the review sentence using a hierarchical topic classification. If we can extract the topic from the review sentence, it is possible to establish a relationship between comics based on the comic content information. Furthermore, we built an exploratory search sys- tem based on the topic.
