Looking Under the Hood : Tools for Diagnosing your Question Answering Engine
In this paper we analyze two question answering tasks : the TREC-8 question answering task and a set of reading comprehension exams. First, we show that Q/A systems perform better when there are multiple answer opportunities per question. Next, we analyze common approaches to two subproblems: term overlap for answer sentence identification, and answer typing for short answer extraction. We present general tools for analyzing the strengths and limitations of techniques for these subproblems. Our results quantify the limitations of both term overlap and answer typing to distinguish between competing answer candidates.

A rule-based question answering system for reading comprehension tests
We have developed a rule-based system, Quarc, that can reada short story and find the sentence in the story that best answers a given question. Quarc uses heuristic rules that look for lexical and semantic clues in the question and the story. We have tested Quarc on reading comprehension tests typically given to children in grades 3-6. Overall, Quarc found the correct sentence 40% of the time, which is encouraging given the simplicity of its rules.
