Dynamic Domain Specific Sentimental Word Identification
Tuesday, November 9, 2010, 12:30pm - Tuesday, November 9, 2010, 14:00pm
In this talk I will outline the problem by presenting new experiments supporting the claim that topical sentiment is expressed by the sum of a large number of very weak signals. As a partial solution I will present a fast, statistically grounded technique to determine sentimental word orientation for a given topic. Then I will present preliminary results using document synthesis to bootstrap topical sentiment polarity classifiers at run time.
