Abstract(in English) Many online reputation sites using evaluative expressions such as blog web site or online shopping site like Amazon.com has been emerged on the Web. The interest for decision support mechanism using online reputation has been increased. We focused our attention on emotional expressions like "happy" or "sad" within many types of evaluative expressions. In this paper, we propose an emotion extraction method and present a prototype system based on this method. In this proposal, we explored the semiautomatic process to produce emotion lexicon collecting flexible length emotional expressions by combining bootstrapping method and Prefixspan which is the technique for a sequential pattern mining. Finally, we report evaluative expressions in the lexicon collected with this process.
