TAILIEUCHUNG - Báo cáo khoa học: "Resource Analysis for Question Answering"

This paper attempts to analyze and bound the utility of various structured and unstructured resources in Question Answering, independent of a specific system or component. We quantify the degree to which gazetteers, web resources, encyclopedia, web documents and web-based query expansion can help Question Answering in general and specific question types in particular. | Resource Analysis for Question Answering Lucian Vlad Lita Carnegie Mellon University llita@ Warren A. Hunt Carnegie Mellon University whunt@ Eric Nyberg Carnegie Mellon University ehn@ Abstract This paper attempts to analyze and bound the utility of various structured and unstructured resources in Question Answering independent of a specific system or component. We quantify the degree to which gazetteers web resources encyclopedia web documents and web-based query expansion can help Question Answering in general and specific question types in particular. Depending on which resources are used the QA task may shift from complex answer-finding mechanisms to simpler data extraction methods followed by answer re-mapping in local documents. 1 Introduction During recent years the Question Answering QA field has undergone considerable changes question types have diversified question complexity has increased and evaluations have become more standardized - as reflected by the TREC QA track Voorhees 2003 . Some recent approaches have tapped into external data sources such as the Web encyclopedias databases in order to find answer candidates which may then be located in the specific corpus being searched Dumais et al. 2002 Xu et al. 2003 . As systems improve the availability of rich resources will be increasingly critical to QA performance. While on-line resources such as the Web WordNet gazetteers and encyclopedias are becoming more prevalent no system-independent study has quantified their impact on the QA task. This paper focuses on several resources and their inherent potential to provide answers without concentrating on a particular QA system or component. The goal is to quantify and bound the potential impact of these resources on the QA process. 2 Related Work More and more QA systems are using the Web as a resource. Since the Web is orders of magnitude larger than local corpora redundancy of answers and supporting passages allows .
