The Design And Implementation Of Website Search Engine Technology Of Web2.0 Community-Oriented

As the explosive growth of network information in recent years, it's more and more difficult to find the useful information you need. The search technology, to a certain extent, can solve this problem, because this technology has maximum access to the information navigation. However, for a specific community website, there is some weakness in timeliness and accuracy of the content. Therefore, it is of practical significance to realize a website search engine in the Weh2.0 community, which would be more timely and accurate than the usual search engine. In this paper, we show the design and implementation of web2.0 community-oriented website search engine technology by addressing some specific issues, and discuss the further development of this technology.This paper introduces the classification and structure of search engine technology, then compares it with three website search technologies, and provides the analyses of present website search technology of Web2.0 community in detail to show the strengths and weaknesses in design and implementation of this technology.Later based on search technology, this paper illustrates the architecture of Web2.0 website search engine, focusing on segmentation and search rank technology. At the segmentation technology, we try to improve the present segmentation and dictionary as well as the efficient of segmentation word, to make it in accordance with the characteristics of web2.0 document. At the search ranking technology, improvements have been made in present search ranking technology to meet Web2.0 document requirements. The application of ranking algorithms of web2.0 community website search engine consists of two parts: the analysis of the content-based ranking algorithm and the structure of the linkage-based ranking algorithm.At last, we implement the website search engine on open source project development platform of web2.0 technology——Trac platform, and do performance testing and functional testing to demonstrate the efficiency and usefulness of this work.The work and contribution of this paper are parts of 863 project"the key technology and system of open source software IP resources library", and have useful theoretical and operational value.
