Abstract
We present in this paper the structure of a textual entailer, offer a detailed view of lexical aspects of entailment and study the impact of syntactic information on the overall performance of the textual entailer. It is shown that lemmatization has a big impact on the lexical component of our approach and that syntax leads to accurate entailment decisions for a subset of the test data.
