Book Overview

Automated question answering - the ability of a machine to answer questions, simple or complex, posed in ordinary human language - is one of today's most exciting technological developments. It has all the markings of a disruptive technology, one that is poised to displace the existing search methods and establish new standards for user-centered access to information. This book gives a comprehensive and detailed look at the current approaches to automated question answering. The level of presentation is suitable for newcomers to the field as well as for professionals wishing to study this area and/or to build practical QA systems. The book can serve as a "how-to" handbook for IT practitioners and system developers. It can also be used to teach advanced graduate courses in Computer Science, Information Science and related disciplines. The readers will acquire in-depth practical knowledge of this critical new technology.

  • This chapter is based on:
  • ABSTRACT: We present in this chapter a description of the major components of a Question-Answering system which has fared well in the three TREC QA evaluations so far, and is currently participating in the ARDA AQUAINT program. Our approach centres around the technique of Predictive Annotation, in which an extended set of named entities is recognized prior to indexing, so that the semantic class labels can be indexed along with text and included in the query string. In addition we present other techniques that are employed for specific question types, such as Virtual Annotation for definition questions. We describe the Answer Selection component, which extracts and ranks answer candidates from the passages returned by the search engine based on linguistic as well as statistical features. We present numerous examples as well as quantitative evaluations.
