Hi all!

This week we have Andreas Vlachos (http://www.biostat.wisc.edu/~vlachos/)
from
University of Wisconsin Madison. Details follow.

When: 2 pm, April 8 (Friday)

Where: 3405, Siebel Center

Title: Bridging the Gap between Pipelines and Structured Prediction in
Biomedical
Event Extraction

Abstract:
We develop a structured prediction approach to biomedical event extraction
using the
Searching to Learn framework which converts the problem of structured
prediction into
multiple cost-sensitive classification (CSC) tasks whose parameters are
learnt jointly.
We evaluate our performance on the BioNLP 2009 shared task datasets and show
that SEARN improves the performance of a pipeline of classifiers learnt
independently
by 7 points in F-score, while maintaining its ease of implementation. In this
process,
we highlight some important aspects of the framework and in particular the
choice of
CSC learning algorithm.

Hoping to see y'all

Thanks!
Rajhans
