  • 基于独立用户的聚类搜索引擎_计算机专业论文范文

    计算机专业论文范文 摘 要 互联网的迅速发展提供了越来越多的网络信息,为了快速检索到所需信息,搜索引擎成为不可或缺的网络应用工具之一。而现有的搜索引擎尽管采用了各种方法来提高检索结果的精度,仍无法排除检索结果中用户查询请求不相关的文档,而且相关文档和不相关文档仍然相互混杂,也给用户带来了额外负担。 本文在对搜索引擎概况和聚类过程分析进行介绍的基础上,设计实现了一个基于聚类的独立用户搜索引擎,帮助Web用户从搜索引擎所返回的大量文档片断中筛选出自己所需要的文档,通过将搜索引擎返回的结果进行聚类为若干个簇类,使得同一簇类内文档相关度尽可能的大,不同簇类间文档相关度尽可能的小,从而大大缩小用户所需浏览的结果数量,缩短用户查询所需要的时间。在系统的设计与实现时,对用户的每次独立搜索请求,我们都采用Yahoo提供的API接口来获取研究所需的源数据,采用倒排文件索引模型建立索引同时采用关键词语的方法表征索引,根据检索结果的标题、URL和网页摘要所含信息计算返回结果网页之间的相似性,并将检索结果以及它们之间的相似性关系映射到无向图,最后根据无向图中每个点的相似度进行聚类最终得到结果。在聚类过程中,本文提出了一种新的聚类方法,该方法首先随机选取几个点作为初时质心,然后依次计算剩余点与质心的相似度并决定是否将其加入某个簇。如果大于某个阀值则将其加入该质心所代表的类并调整质心的位置,直至加入全部的点。理论分析表明,系统采用的倒排文件模型需要较少的资源,所提出的聚类算法在一定程度上解决了文档多义性问题,同时系统对孤立点问题也进行了相应的处理。实验结果也表明,本文所提的聚类方法具有较好的效果,能对返回结果进行有效聚类。 关键词:搜索引擎,聚类,索引,相似度 Clustering Search Engine Based on Independent Users Abstract The rapid development of the Internet has provided more and more internet information. In order to search the required information rapidly, search engines have become one of the indispensable internet tools. Nowadays, although many search engine systems have been applying many methods to improve the retrieva l precision, the retrieved results still include a lot of irrelevance documents mixing with the relevance ones, and it brings users an additional burden. Based on the profile of search engines and cluster analysis, the clustering search engine for the independent users is designed. It helps the web users choose required information from along list of returned snippets, clustering of the retrieved results will assign snippets to automatically groups based on calculating the similarity. The groups (clusters) formed should have a high degree of association between members of the same groups and a low degree between members of different groups. So the users can only view their interested groups and save much time. In the process of design and implementation, when a independent search request is send to the search engine, the Yahoo API is used to obtain the necessary research data sources in our system and inverted files indexing model is used to create index while using the key words denoting index. The similarity is calculated according to the title of retuned results, URL and summary in our system, then search results and their relationship of similarity are mapped to an undirected graph. Finally, the points of the undirected map are clustered according to the similarity of each point in the undirected map and the ultimate results are gotten. During the clustering process, a new clustering method is proposed. Firstly, the method randomly selects a few points as initial centers. Secondly, each point is gradually added one or several clusters based on re-calculation of the similarity between added point and each center. If the similarity is greater than predefined threshold, the point will be added some cluster, whose center are adjusted until adding all the points. Theoretic analysis shows that the used reverted file model in our system needs little resources and proposed clustering algorithm resolves the problem of . And the isolating point problem is also considered. Experimental results also show that the proposed method has better clustering performance and the returned results can be clustered effectively.

  • 基于Domino平台的OA设计与实现_计算机专业论文范文

    计算机专业论文范文 摘要 随着OA系统在日常办公中的普及,越来越多的公司致力于开发OA系统,而使用的开发模式、开发平台也多种多样。实现OA系统的常见平台有:Microsoft、JSP/Java、Domino,三种平台各有所长。相对其它两种,Domino在时间成本、服务成本上都优势。因为Domino开发数据库的同时开发界面,所以开发周期短,Domino服务器可以集多种服务器于一体,包括文档数据服务器、邮件服务器、应用服务器,故服务成本低。Domino中功能的实现和其它的开发工具不同,因为Domino中开发元素多种多样,同一功能可以用不同的方法实现,所以毕业设计中实现的2个模块考勤管理、车辆管理中功能点通过多种方法实现。 OA的发展促使OA系统间或者OA系统与门户等其他系统间的交互越来越频繁,为了延长系统的生命周期和提高客户的满意度,开发接口是必不可少的。开发接口的方法也有很多,本文分析了三种实现方法,分别为利用Lotus Script、Java虚拟机、LEI技术。其中因为LEI技术是IBM公司开发的新技术,该技术的主要思想是利用Connection以及Activity确定要交互的数据以及路径。通过分析三种技术,了解到用Java虚拟机完成数据交互最不可取,而LEI服务成本高,编写Lotus Script代码需要的时间成本高,如何取舍要分情况讨论,用不同的方法实现了实际问题中的5个接口。 Domino作为一个文档型的数据库,IBM公司表示Domino 8 后将不再开发新的版本,这势必导致使用Domino的用户数量降低。而且由于Domino中数据底层和表现层是同时设计的,没有很好的分层,而当面向对象成为一种必然的时候,这就是比较落后的。但Domino中还是存在比较优秀的OA设计方法和较好的工作流引擎。 关键字:OA, Lotus, Domino, Notes, Lotus Script, LEI, JMV The design and realization of Office Automation Abstract With Office Automation system in the daily office popularity, more and more companies dedicate to the development of OA system, furthermore, their development modes used and the development platforms are diverse. The common realization methods of OA system include based on the Microsoft platform, JSP/Java platform or Domino platform, the three have their own strengths. Compared to the two other methods, the realization of OA system in Domino whether time cost or service cost both have certain advantages. Because Domino as object-based database, it develops database while also developing the interface, and Domino server can integrate multiple server as a whole, including file data server, mail server, application server. Due to the diverse elements, the realization of functions in Domino differs from other development tools, the same function can also use different methods to implement. The development of OA promotes frequent interactions between OA systems or OA system and gateway systems and other increasingly, In order to extend the system's life cycle and improve customer satisfaction meanwhile, the interface development is essential. There are a lot of methods to develop interface, this paper analyzed three realization methods: use Lotus Script, Java Virtual Machine, LEI technology for realization. For LEI is a new technology developed by IBM Company, the main idea of which is to use Activity and Connection to identify the following interactive information and paths. By analyzing the three technology, we learned that completion interactive tasks using Java Virtual Machine is the most undesirable, while LEI has the high service cost and LS coding has the high time cost, how to choose needs discuss on a specific situation. Domino as a document-based database, IBM Company said that they will not develop new versions after Domino 8. This will inevitably lead to the decrease of Domino users. Moreover because the bottom data layer and performance layer in Domino are synchronously designed with not good hierarchical structure, but when the object-oriented has become inevitable, Domino has been comparatively behindhand. However, there are relatively good design ideas and a better workflow engine still in Domino.
