The Design And Implementation Of Red Net Portal Intelligent Search

As a key News websites and a comprehensive web site, Rednet is the No. One of the Chinese local News website providing a variety of news release, live video broadcast,forum and blog, and other services. It creates a strong regional network media actively,and becomes a comprehensive network service platform among which the Hunan News portal website is the most famous one. When establishing the construction route according to Rednet IT supporting system standards, it may need to make unified management for the office system, portal, e-mail and other resources.But there are difficulties in statistical query, various system function, complex paths,as well as large volume of information, so it causes great operation inconvenience for the users. Also it results in the users can't find out the data because of route unfamiliar. In order to solve this problem, it needs to fulfill the search function in the new office system.The key technologies included in this thesis are Crawler Technology, Chinese word Segmentation Technology,Data Mining Technology,Full-text Retrieval Technology, and Data Caching Technology. Lucene is used as text document indexing and searching. The intelligent portal search, also the research of this thesis,contributes to the Rednet to in achieving electronic, exquisite and process management. It is good for the integrated management of the resource about new office system, document system, portal system and other system, also good for search function within a website, thus realizes full-text retrieval for the text information,emails, worksheet information and other unstructured data. Meanwhile it provides a friendly display, helps the users to define and find out the data quickly, improves the whole system usability, and contributes a lot for users work efficiency improvement.The main work of this thesis is to analyze the business requirements of the Rednet portal intelligent search, with generally design of the overall system functionality, content functional architecture, technical architecture, network topology,function modules, etc. and detailed design for the front-end display function, reptiles function, indexing, retrieval function and system management functions, and finally with the system platform setup and implement, and obtains practical achievements.The search engine is widely used by the Rednet users, greatly improved the portal user experience. The technical innovation of this thesis is the tagmanagement of the portal website web pages, internal documents of the Rednet and other information resources, and the quickly positioning fulfillment of relevant information through index searching. This thesis also makes some index comparison of search coverage, search precision, search speed and other indicators to Rednet portal intelligent search, and the Chinese search engines such as Baidu, Sogou etc.and draws the relevant conclusions.Through the study of this subject, the portal website Rednet‘s site search engine can assist the relevant personnel for a better and efficient use of portal system,realizing the fast search and positioning of relevant documents for the Rednet portal user system, realizing the analysis and classification of the documents related to the Rednet portal user system. And it displays the search results in a friendly and concise way, helping the users to access to the information needed from the system, liberated from the cumbersome research and improved the efficiency of the system application greatly. In one word, the system development helps the Rednet achieve fast positioning the system internal resources, improve the efficiency of resource searching, and reduce the time cost.
