Abstract

Great progress has been made on sentiment analysis techniques for
in the English language; however, for other languages, sentiment
analysis is less well understood. This thesis reports on statistical
analysis of sentiment in Japanese and English text. Salient features
for each are analyzed to better understand how authors convey
sentiment. In particular, socio-psychological and linguistic
explanations are given for their usage. In addition to proposing
linguistic insights and hypothesis, the foundation is laid for more
effective automatic sentiment classification for non-English
languages.
