新一代网络搜索系统ASK MSR的结构分析

Analyzing into a New Generation of Web Search System 's Architecture Named ASK MSR

针对现有搜索引擎准确度不高,所得结果仍需用户花费大量精力筛选的现状,Microsoft提出一种基于"问题—回答"系统的新型搜索系统。它对一个给定的问题,经过问题解析,网上搜索,过滤筛选,答案提取等几步,能给出相对应的直接答案。本文着重介绍了该系统的核心部件"问题—回答"系统的体系结构及其各组成部件的工作原理。

The precision of existing search engines aren't high enough. Users must spend many times selecting the information that they need in the results. Microsoft presents a new search engine based on the QA system. It can offer direct answer to a given question. The process includes question analyzing, searching, filtering, and answer extracting. The paper describes emphatically the QA system's architecture and their component's work principle.
