【摘要】：本文作者对所在单位的实际情况和面临的主要问题出发,即小型研究机构中从事研究工作的人员对搜索引擎具有较高的使用需求,而个人使用搜索引擎的技巧和能力参差不齐,造成许多研究人员在使用搜索引擎查找所需的信息时存在费时费力且效果不佳的问题。作者针对这一实际问题,希望设计一款桌面级综合搜索工具,可以方便研究人员在工作中对网络搜索引擎使用。一方面,该工具需要具有元搜索引擎的一些特点,可以同时返回多个综合搜索引擎的搜索结果,并进行整合排序,用户通过一次检索操作即可得到多个综合搜索引擎的结果,另一方面,该工具还应具备让用户根据自身需要,选择垂直搜索引擎的功能,针对特定搜索需求获得更为专业、具体的搜索结果。本文从搜索引擎的发展变化出发,分析其针对用户使用需求所做出的改变,并引出元搜索引擎、垂直搜索引擎等搜索领域的其他重要工具。根据对元搜索引擎的工作方式、优势和不足等进行分析对比,明确本单位实际用户的使用特点和具体需求,确定本文所设计的工具应该具备的主要功能、在结果处理、排序去重等环节采用的基本设计思路,并分别介绍用户兴趣概念模型、系统架构、数据库设计等设计思路。
[Abstract]:The author sets out from the actual situation of the unit and the main problems, that is, the personnel engaged in research work in small research institutions have a high demand for the use of search engines, while the skills and abilities of individuals in using search engines are not uniform. Many researchers use search engines to find the information they need. Aiming at this practical problem, the author hopes to design a desktop level comprehensive search tool, which can be used by researchers in the work of the network search engine. On the one hand, the tool needs to have some characteristics of meta search engine, it can return the search results of multiple integrated search engines at the same time, and carry on the integration sorting, the user can get the results of multiple integrated search engines through one retrieval operation. On the other hand, the tool should also have the function of allowing users to select vertical search engines according to their own needs, so as to obtain more professional and specific search results for specific search needs. Starting from the development and change of search engine, this paper analyzes the changes made by the search engine in response to the user's needs, and leads to other important tools in the field of search such as meta search engine, vertical search engine and so on. According to the analysis and comparison of the working mode, advantages and disadvantages of the meta search engine, the use characteristics and specific needs of the actual users of the unit are clarified, and the main functions of the tools designed in this paper are determined to deal with the results. This paper introduces the basic design ideas of sorting and removing, and introduces the concept model of user interest, system architecture, database design and so on.
