Implicature in Opinion Analysis

While previous sentiment analysis research has concentrated on the

interpretation of explicitly stated opinions and attitudes, this work

addresses the computational study of a type of opinion implicature

(i.e., opinion-oriented inference) in text.  This talk will describe a

framework for representing and analyzing opinion implicatures which

promises to contribute to deeper automatic interpretation of

subjective language.  In the course of understanding implicatures, the

system recognizes implicit sentiments (and beliefs) toward various

events and entities in the sentence, often attributed to different

sources (holders) and of mixed polarities; thus, it produces a richer

interpretation than is typical in opinion analysis.

Janyce Wiebe is Professor of Computer Science and Co-Director of the

Intelligent Systems Program at the University of Pittsburgh.  Her

research with students and colleagues has been in discourse

processing, pragmatics, and word-sense disambiguation.  A major

concentration of her research is "subjectivity analysis", recognizing

and interpretating expressions of opinions and sentiments in text, to

extraction, text categorization, and summarization.  Her professional

roles have included ACL Program Co-Chair; NAACL Program Chair; NAACL

Executive Board member; TACL Action Editor; Computational Linguistics and Language

Resources and Evaluation Editorial Board member; AAAI Workshop
