Title: Discourse Analysis and Summarization of asynchronous conversations
For many business intelligence applications, decision making depends
critically on the information contained in all forms of “informal”
text documents, such as emails, blogs and meeting summaries. For
example, in a meeting, the topic of developing a new product was first
raised. In subsequent follow-up emails, additional comments and
discussions were added, which included links to web documents
describing similar products in the market and user reviews on those
products. A discourse analysis and extraction of features from this
“conversation” is valuable for browsing and understanding of the
underlying data. A concise, natural language summary is also beneficial
for many applications.
In this presentation, we give an overview of our research program on
discourse analysis of asynchronous conversations. We discuss our recent
studies on topic modeling, dialog acts extraction and rhetorical parsing.
We also overview our approaches for abstractive summarization. (This
program has been partially funded by Google, IBM and SAP.)
Short bio:
Dr. Raymond Ng is a professor in Computer Science at the University of
British Columbia. His main research area for the past two decades is on
data mining, with a specific focus on health informatics and text mining.
He has published over 150 peer-reviewed publications on data clustering,
outlier detection, OLAP processing, health informatics and text mining.
He is the recipient of two best paper awards - from 2001 ACM SIGKDD
conference, which is the premier data mining conference worldwide, and
the 2005 ACM SIGMOD conference, which is one of the top database
conferences worldwide.
