The question's semantic comprehension model combines many natural language processing techniques, including Segmentation and Part-Of-Speech Tagging, the confirmation of the question type, the extarction of keywords and extending, the confirmation of the knowledge unit, Through these works, the intention of the user is holded, which greatly helped the last work of this system. The FAQ-based question similarity match model is implemented by sematic sentence similarity computation, which is improved by our system, this model can answer frequently-asked question fastly and concisely.The document warehouse-base automatic answer fetching model fistly deal with the document warehouse beforehand and construct inversed index, then use high efficient information retrieval model to search in the base and return some relevant documents, lastly, we use answer extraction technique to get the answer from these relevant documents and present it to users.

问句理解分析模块采用分词和词性标注、关键词提取及扩展、问句类型类别确定等自然语言理解技术，实现对用户提问意图的准确理解；FAQ 库问句匹配模块主要采用本系统改进的句子相似度计算方法来实现用户问句的解答，该模块主要用于实现用户常问问题的快速、准确解答；学科文档库答案自动获取模块在对学科文档库建立倒排索引的基础上，采用高效的信息检索模型对索引库进行检索，返回与用户查询表达式相似度较高的文档作为候选文档，针对从文档中直接获取答案难度较大这一问题，本系统采用答案抽取技术来实现问题的最终回答。

In this paper, some methods of fuzzy mathematics suah as the direct method of fuzzy pattern recognition, the method of fuzzy clustering analysis the method of fuzzy information retrieval, and the recently advanced method of fuzzy fractal dimension have been applied to earthquake monitoring and prediction in the Surrounding Capital Area based on the seismicity and earthquake precursors. The seismic and unseismic precursors before both the Tangshan M=7.8 great earthquake in July, 1976 and the Datong-yanggao M...

本文把模糊数学中的模糊模式识别的直接方法、模糊聚类分析方法、模糊信息检索方法和新近提出的模糊分维方法应用到以地震活动性和地震前兆为基础的首都圈地震监测预报当中，分析研究了发生在这一地区的两次大地震，即1976年唐山7.8级和1989年大同6.1级地震前用模糊数学方法识别出的地震学前兆和非地震学前兆，并对这一地区大地震的长期和中短期模糊预报方法与途径进行了简要的讨论。

The cause of topic drifting away in HITS algorithm is analyzed. By combining the topic analysis method with that of the content relevance evaluation, we present a novel web information retrieval algorithm－WHITS.

文本在简要介绍HITS算法的基础上，分析了其产生主题漂移的原因，并结合内容相关度评价方法，提出了一种新的搜索算法——WHITS算法。

Answer: ATi graphics driver of the Bug from there up to now has not one or two days, and this is because in the run-time 3DMARK first graphics device information retrieval, if the search is not successful will be repeated this action, the program will not be able to normal operation.

答：ATi显卡驱动中的这个Bug从出现到现在已不是一天两天了，这是因为3DMARK在运行时首先要检索图形设备信息，若检索不成功便会不断重复这一动作，程序就无法正常运行。

Web contenting and Web structure mining are becoming the core of third generation search engine, and improves information retrieval on the Web to a high quality and intelligent level.

在完成Web挖掘理论研究的基础上，我们实现了一个基于Web挖掘算法的分布式信息检索平台LUKA，它包括了分布式Web文档收集、Web挖掘算法、分布式Web链接分析算法、半结构化文档概念索引等多个模块，它们有机的组成了一个Web信息挖掘的原型系统。

It is not a matter of starting from square one, as Croft (1995) would say, when referring to the current lines of research in information retrieval, but rather of reorienting efforts.

正如 Croft （1995）谈到在信息检索方面的研究现状时所说，这不是从起点开始，而是努力的方向。
