The Effect of Entity Recognition in the Answer Validation

The Answer Validation Exercise (AVE) 2006 is aimed at developing systems able to decide whether the answer of a Question Answering (QA) system is correct or not using textual entailment. The most answers to be validated are given from questions that need entities as responses. The paper presents a system that has only used entities to participate in the AVE 2006. The results of the propose system are better than the ones of a baseline system that always accepts all answers, therefore the use of entities can improve the results of an answer validation system
