Exploring the use of paragraph-level annotations for sentiment analysis of financial blogs.
In: WOMAS 2009 - Workshop on Opinion Mining and Sentiment Analysis, 13 November 2009, Seville, Spain.
In this paper we describe our work in the area of topic-based sentiment analysis in the domain of financial blogs. We explore the use of paragraph-level and document-level annotations, examining how additional information from paragraph-level annotations can be used to increase the accuracy of document-level sentiment classification. We acknowledge the additional effort required to provide these paragraph-level annotations, and so we compare these findings against an automatic means of generating topic-specific sub-documents.
