中文摘要:
      微软小冰引发了问答系统的新一轮研究热潮。作为一种新型的信息检索方式,问答系统能直接以自然语言与用户进行人性化的交互。而基于Web的问答系统能通过搜索引擎获取开放的互联网上的各种相关信息,并将以自然语言形式表述的准确答案返回给用户,因此此类系统同时具有搜索引擎和问答系统的优点。首先,对基于Web的问答系统的研究背景与发展历史进行了概述;然后,详细介绍了基于Web的问答系统的架构及其问题分析、信息检索、答案抽取这三大关键技术的研究进展;在此基础上,分析了基于Web的问答系统所面临的问题;最后,对基于Web的问答系统的未来发展趋势进行了展望。
英文摘要:
      Microsoft Xiaoice triggers a new round of boom on question answering research.As a new kind of information retrieval technology,question answering offers friendly interaction for users by using natural languages.Web-based question answering extracts answers in natural languages for users’ questions from search results provided by search engines.Web-based question answering has both advantages of search engine and question answering.Firstly,background and history of web-based question answering were summarized.Then,the research progress of the three key technologies of web-based question answering(question analysis,information retrieval and answer extraction) were introduced in detail.Based on the above introduction,the problems to be solved of web-based question answering were analyzed.Finally,the future research trend of web-based question answering was discussed.
