Research Abstract

I have proposed "syntactic piece" as a language processing unit of Japanese. Syntactic piece is the smallest unit that keeps syntactic relation. I have shown in this grant that the syntactic piece outperforms other units such as n-gram and bag-of-words, in the task of sentiment analysis and automatic summarization.
