Title: Adaptation of sequence models in novel domains
 
Abstract:
 
This is work in progress with Massimiliano Ciaramita. We investigate the
adaptation of structured classifiers to novel domains; in particular, the
problem of using a supervised Named-Entity Recognition (NER) system on data
from a different source than the training data. We study a Semi-Markov
Model, trained with the perceptron algorithm, coupled with an external
dictionary with the goal of improving generalization on the novel domain.
Preliminary experiments show promising results, obtained with very simple
additional features.
