It is generally accepted that sentiment analysis is a more\nchallenging clas sification problem then topic categorization and here\nthe bag of words ap proach does not perform as well. Using the IMDB\nsentiment dataset from Co rnell University\, we improve on their results\nby using a stacked classif ier and web-mined features.\n DTSTAMP:20221003T055941Z END:VEVENT END:VCALENDAR
