 ntiment-classification-approach-using-stacked
LOCATION:DC - William G. Davis Computer Research Centre 200 University Aven
 ue West 2306C (AI lab) Waterloo ON N2L 3G1 Canada
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.

SUMMARY:AI seminar: Specialized multi-agents learning system
CLASS:PUBLIC
DESCRIPTION:Speaker: Nasser Mooman\n\nWith the increasing amount of availab
 le information sources for\nlearners\, the need for systems that can effec
 tively and efficiently\nmine\, retrieve\, and process such information has
  become critical.

 ue West 2306C (AI lab) Waterloo ON N2L 3G1 Canada
SUMMARY:AI seminar: Dealing with word sense disambiguation in lexical chain
 ing
CLASS:PUBLIC
DESCRIPTION:Speaker: Mattt Enss\n\nA lexical chain is a sequence of words i
 n a document that are\nsemantically related (i.e.\, related in meaning). L
 exical chains\nindicate where certain topics or subjects are being discuss
 ed in a\ndocument. The chains therefore can provide context and be used to
 \ndetermine where topic changes occur.

LOCATION:DC - William G. Davis Computer Research Centre 200 University Aven
 ue West 2306C (AI lab) Waterloo ON N2L 3G1 Canada
SUMMARY:AI seminar: Structuring interactive cluster analysis
CLASS:PUBLIC
DESCRIPTION:Speaker: Wayne Oldford (Dir. of Computational Math\, UW)\n\nThe
  problem of cluster analysis\, or finding groups in data\, is\ninherently 
 ill-posed\; hence the multitude of different methods which\npurport to sol
 ve \"the'' problem. In this talk\, a variety of examples\nillustrate this 
 point and cast doubt on whether a single universally\nuseful clustering me
 thod exists.

SUMMARY:AI seminar: Who's asking for help? A Bayesian approach to intellige
 nt\nassistance
CLASS:PUBLIC
DESCRIPTION:Speaker: Bowen Hui (University of Toronto)\n\nAutomated softwar
 e customization is drawing increasing attention as a\nmeans to help users 
 deal with the scope\, complexity\, potential\nintrusiveness\, and ever-cha
 nging nature of modern software. The\nability to automatically customize f
 unctionality\, interfaces\, and\nadvice to specific users is made more dif
 ficult by the uncertainty\nabout the needs of specific individuals and the
 ir preferences for\ninteraction.

SUMMARY:AI seminar: Why bother about bother: Is it worth it to ask the user
 ?
CLASS:PUBLIC
DESCRIPTION:Speaker: Robin Cohen\n\nIn this paper\, we discuss the importan
 ce of modeling the potential\nbother to the user\, when reasoning about in
 teraction in a\nmixed-initiative setting. We summarize our previous work o
 n modeling\nbother as one of the costs of interaction\, clarifying how to\
 nincorporate this estimated cost when reasoning about whether to\ninitiate
  interaction.

SUMMARY:AI seminar: Ontologies: Mature research tools?
CLASS:PUBLIC
DESCRIPTION:Speaker: Rob Warren\n\nOntology research has had a renewed inte
 rest with the release of two\nontological markup standards\, DAML+OIL and 
 OWL\, in December of 2001\nand March of 2002.\n\nIn this talk I'll review 
 some of the work I did while at the Fungal\nWeb Project in Montreal\, wher
 e we faced several questions about the\nuse and adoption of ontologies and
  their markup languages:
