A Semantic Approach To Textual Entailment: System Evaluation and Task Analysis

Aljoscha Burchardt, Nils Reiter, Stefan Thater, Anette Frank

Abstract: This paper discusses our contribution to the third RTE Challenge -- the SALSA RTE system. It builds on an earlier system based on a relatively deep linguistic analysis, which we complement with a shallow component based on word overlap. We evaluate their (combined) performance on various data sets. However, earlier observations that the combination of features improves the overall accuracy could be replicated only partly.
