Abstract

The TREC-8 Question Answering track was the first large-scale evaluationof domain-independent question answering systems.This paper summarizes the results of the track by giving a briefoverview of the different approaches taken to solve the problem.The most accurate systems found a correct response for more than 2/3of the questions.Relatively simple bag-of-words approaches were adequate for findinganswers when responses could be as long as a paragraph (250 bytes),but more sophisticated processing was necessary for more directresponses (50 bytes).
