The Research And Implementation Of Topic-Searching Engine System For Meteorology Based On The .NET

Along with the rapid growth of information on Web, Search engines becomes the most important information query tools from the WWW and the key to the internet research and utilization.Following the WWW information multivariant growing up, Topic-Search Engines are becoming researching focus. This dissertation focused on the topic specific Chinese web information accessing and its screening technology, designed and accomplished a Meteorology Search Engine system which kernel was the topic specific information gathering based on the meta-search engine.Firstly introduced history and present condition of nowadays general purupose comprehensive search engines, introduced the topic search engine background and working mechanism. Eduction the implement method of this system. With the meteorology background, this paper focus its research on a new specialized, intelligent Web information retrieval system based on meta-search engine, and gives a systematic implementation by. NET and Sql Server 2000, building an Meteorology Search Engine. Analysis functional modules and the key technology, such as meta-search engine interface,information blend,filter and ranking etc.This system face to Meteorology domain. Assured the completeness and renewedness and avoid the noise in search. It increase the scope of the acquiring information and the precision of the search, enhancing the rate and precision of the retrivel, realized the Meteorology information search quickly, completely and accurately. Which provides an effective method to acquire info in web for the Meteorology user.At present, this system can run experimental and well result., Which achieved the anticipated learning and practicaling effect. Establishing basis for further research and develop Topic-Search Engine.
