Rhetorical Structure Analysis and its Application to Sentiment Summarization
K.C. Irving Centre - Auditorium, Acadia University
Speaker: Dr. Raymond Ng, Professor - Computer Science Department, University of British Columbia
Abstract: For many business intelligence applications, decision making depends critically on the information contained in all forms of text documents. Rhetorical parsing of documents has been studied for decades. In the first half of this talk, we give an overview of recent advances. In the second half, we present our latest results on using rhetorical structure and relationships for sentiment summarization.
