SUMMARY:AI seminar: A sentiment classification approach using stacked\nsupe
 rvised learning incorporating web mined features
CLASS:PUBLIC
DESCRIPTION:Speaker: Rejean Lau (University of Alberta)\n\nSentiment classi
 fication is a form of the text categorization problem\nwhere user sentimen
 t is categorized as either positive or negative\nsentiment. It is generall
 y accepted that sentiment analysis is a more\nchallenging classification p
 roblem then topic categorization and here\nthe bag of words approach does 
 not perform as well. Using the IMDB\nsentiment dataset from Cornell Univer
 sity\, we improve on their results\nby using a stacked classifier and web-
 mined features.
