Title: Numbat: Abolishing Privileges in Constraint-Oriented Parsing
Speaker: Jean-Philippe Prost

This talk will be a dry-run for the presentation of my paper at the CSLP-06 workshop, on Constraints and Language Processing. Following is the paper's abstract.

The constraint-oriented approaches to language processing step back from the generative theory and make it possible, in theory, to deal with all types of linguistic relationships (e.g. dependency, linear precedence or immediate dominance) with the same importance when parsing an input utterance. Yet in practice, all implemented constraint-oriented parsing strategies still need to discriminate between "important'' and "not-so-important'' types of relations during the parsing process. 

In this paper we introduce a new constraint-oriented parsing strategy based on Property Grammars, which overcomes this drawback and grants the same importance to all types of relations.


Title: Marking Time in Developmental Biology:  Annotating Developmental Events and their Links with Molecular Events
Speaker: Gail Sinclair (University of Edinburgh)

Current research in developmental biology aims to link developmental genetic pathways with the processes going on at cellular and tissue level.  Normal processes will only take place under specific sequential conditions at the level of the pathways.  Disrupting or altering pathways may mean disrupted or altered development. 

Most relation extraction work to date on biomedical articles has focused on genetic and protein interactions, e.g. the extraction of the fact that expression of Gene A has an effect on the expression of Gene B.  However, where genetic interactions are tissue- or stage-specific, the conditions that govern the types of interactions often depend on where in the body the interaction is happening (space) and at what stage of life/development (time).  For the understanding of genetic pathways involved in development, it is critical to link what is happening at the molecular level to changes in the developing tissues. 

This presentation will describe the work I have done in detecting and extracting information on developmental events from free text and on their relations in space and time.
