style="font-family:Calibri,sans-serif">In this presentation
Stan Matwin will review the current work at the Text
Analysis and Machine Learning Lab, University of Ottawa,
Canada. Research in text mining focuses on the data model
and use of additional symbolic (or statistical) knowledge to
enrich the process. A recent application is following tweets
of different parts of the political spectrum in the
presidential election in France. Research in data privacy
looks at the algorithms that can perturb the data so that
privacy is preserved while the quality of the data remains
acceptable. Research in mining trajectories of moving
objects examines patterns of movements of ships and builds
models allowing prediction of events in maritime traffic. We
will also touch on current research in machine learning for
face recognition in video data, and in proposing a new
classifier performance measure that addresses certain
shortcomings of the standard ROC curves.</span></p>
