Abstract
The Web is apparently an ideal source of answers to a large variety of questions, due to the tremendous amount of information available online. This paper describes a Web-based question answering system LAMP, which is publicly accessible. A particular characteristic of this system is that it only takes advantage of the snippets in the search results returned by a search engine like Google. We think such “snippet-tolerant” property is important for an online question answering system to be practical, because it is time-consuming to download and analyze the original web documents. The performance of LAMP is comparable to the best state-of-the-art question answering systems.
