چکیده

This paper describes our system of recognizing textual entailment for RTE-5 challenge at TAC 2009. We propose a textual entailment recognition framework and implement a system of classification which takes lexical, syntactic and semantic features as considered. To improve the performance, some lexical-semantic resources and web knowledge bases are also incorporated in the system. Official results show that our system achieves a medium performance of all participating systems.

A Belief Revision Approach to Textual Entailment Recognition

An artificial believer has to recognize textual entailment to categorize beliefs. We describe our system – the Fuzzy Believer system – and its application to the TAC/RTE three-way task.

AUEB at TAC 2009

This paper describes AUEB’s participation in TAC 2009. Specifically, we participated in the textual entailment recognition track for which we used string similarity measures applied to shallow abstractions of the input sentences, and a Maximum Entropy classifier to learn how to combine the resulting features. We also exploited WordNet to detect synonyms and a dependency parser to measure simila...

Using Textual Entailment with Variables for KBP Slot Filling Task

This report presents our extension of the textual entailment paradigm, in which variables are incorporated in the hypothesis, and are lled with extracted information during the entailment recognition process. This paradigm is the basis for a novel approach of using variables in textual entailment, with various potential future applications. We experimented with this approach in the TAC 2012 Kno...

A Joint Syntactic-Semantic Representation for Recognizing Textual Relatedness

This paper describes our participation in the Recognizing Textual Entailment challenge (RTE-5) in the Text Analysis Conference (TAC 2009). Following the two-stage binary classification strategy, our focus this year is to recognize related Text-Hypothesis pairs instead of entailment pairs. In particular, we propose a joint syntactic-semantic representation to better capture the key information s...
