Abstract

We present our CoNLL-2010 Shared Task system in the paper. The system operates in three steps: sequence labeling, syntactic dependency parsing, and classification. We have participated in the Shared Task 1. Our experimental results measured by the in-domain and cross-domain F-scores on the biological domain are 81.11% and 67.99%, and on the Wikipedia domain 55.48% and 55.41%.
