Where: 3405, Siebel Center
Title: Bridging the Gap between Pipelines and Structured Prediction in Biomedical
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
