چکیده

This paper is about our approach to answer validation, which centered by a Recognizing Textual Entailment (RTE) core engine. We first combined the question and the answer into Hypothesis (H) and view the document as Text (T); then, we used our RTE system to check whether the entailment relation holds between them. Our system was evaluated on the Answer Validation Exercise (AVE) task and achieved f-measures of 0.46 and 0.55 for two submission runs, which both outperformed others’ results for the English language.

Paraphrase Substutution for Recognizing Textual Entailment

We describe a method for recognizing textual entailment that uses the length of the longest common subsequence (LCS) between two texts as its decision criterion. Rather than requiring strict word matching in the common subsequences, we perform a flexible match using automatically generated paraphrases. We find that the use of paraphrases over strict word matches represents an average F-measure ...

DFKI-LT at AVE 2007: Using Recognizing Textual Entailment for Answer Validation

This report is about our participation in the Answer Validation Exercise (AVE) 2007. Our system utilizes a Recognizing Textual Entailment (RTE) system as a component to validate answers. We first change the question and the answer into Hypothesis (H) and view the document as Text (T), in order to cast the AVE task into a RTE problem. Then, we use our RTE system to tell us whether the entailment...

Recognizing Textual Entailment: Models and Applications

Recognizing textual entailment (RTE) has been proposed as a task in computational linguistics under a successful series of annual evaluation campaigns started in 2005 with the Pascal RTE-1 shared task. RTE is defined as the capability of a system to recognize that the meaning of a portion of text (usually one or few sentences) entails the meaning of another portion of text. Subsequently, the ta...

Overview of the Answer Validation Exercise 2006

The first Answer Validation Exercise (AVE) has been launched at the Cross Language Evaluation Forum 2006. This task is aimed at developing systems able to decide whether the answer of a Question Answering system is correct or not. The exercise is described here together with the evaluation methodology and the systems results. The starting point for the AVE 2006 was the reformulation of the Answ...
