Comparison of Feature Usage at TSC-3 Summarization Tasks

We participated in two summarization tasks at the TSC-3. We have introduced categorization of feature values for our summarization system, which is based on sentence extraction technique. The categorized val- ues were used as features for generating a decision tree. We compared our summarization system using the categorization of feature values with the one using linear combination of features in evaluation results of the TSC-3 tasks.
