On the AWAI 2012, on Friday, we will be visiting the Katholieke Universiteit Leuven. There is now more information on our programme there:
10 uur: Opening (Danny De Schreye)
10.05 uur: Machine Learning Group (Prof. Luc De Raedt)
An overview will be given of a number of core activities around Machine Learning in the DTAI group, where the emphasis is on processing structured data (relational representations), usage of probabilistic logics and the integration of constraint programming and data mining. This will be illustrated using applications in game playing, robotics, vision and life sciences.
11.00 uur: Language Intelligence & Information Retrieval group (Prof. Sien Moens)
Machine Understanding of Text: A Complex Puzzle to Unravel
Marie-Francine Moens (Information Retrieval, Katholieke Universiteit Leuven, Belgium)
Machine understanding of text is a long-term goal of artificial intelligence research. Current technologies are already quite successful at extracting factual information from text. Their scope is, however, limited to, for instance, the recognition of individual events and their participants, and their temporal and locational settings. Connecting the different, often uncertain extractions into more complex discourse structures (e.g., the timeline of the events in a story, the premises and conclusions in argumentation, concepts that are composed of events and their causal relations) is much more difficult. In addition, the validity of an extraction is usually reinforced by the availability of other information present in a text or in other sources.
In this lecture we discuss current technologies and their performance for story understanding, argumentation recognition and concept extraction. We point to the problems that need further research and to promising techniques that rely on language models, alignment, evidence combination and uncertainty reasoning.
We illustrate the talk with our own research results in European and national projects.
12 uur: Lunch
13.30 uur: Computational Neuroscience group (dr. Marijn van Vliet)
14.30 Afsluiting
