| 英文摘要 |
People often publish online texts to express their stances, which
reflect the essential viewpoints they stand. Stance identification
has been an important research topic in text analysis and
facilitates many applications in business, public security and
government decision making. Previous work on stance
identification solely focuses on classifying the supportive or
unsupportive attitude towards a certain topic/entity. The other
important type of stance identification, multiple stance
identification, was largely ignored in previous research. In
contrast, multiple stance identification focuses on identifying
different standpoints of multiple parties involved in online texts.
In this paper, we address the problem of recognizing distinct
standpoints implied in textual data. As people are inclined to
discuss the topics favorable to their standpoints, topics thus can
provide distinguishable information of different standpoints. We
propose a topic-based method for standpoint identification. To
acquire more distinguishable topics, we further enhance topic
model by adding constraints on document-topic distributions.
We finally conduct experimental studies on two real datasets to
verify the effectiveness of our approach to multiple stance
identification. |
