    <Paragraph position="0"> In this paper we presented the definition of two entailment models, Lexical and Lexical-Syntactic, and analyzed their performance manually. Our experiment shows that the lexical-syntactic level outperforms the lexical level in all measured aspects. Furthermore, paraphrases and syntactic transformations emerged as the main contributors to recall. These results suggest that a lexical-syntactic framework is a promising step towards a complete entailment model.</Paragraph>
    <Paragraph position="1"> Beyond these empirical findings we suggest that the presented methodology can be used generically to annotate and analyze entailment datasets.</Paragraph>
    <Paragraph position="2"> In future work, it would be interesting to analyze higher levels of entailment, such as logical inference and deep semantic understanding of the text.</Paragraph>
