【Abstract】 Neither the general search engine nor the site search mechanism provided by websites is able to achieve the content-based search of corporate websites information. After analysing the types of corporate websites information,we proposed a general site search engine architecture for this problem. Apart from discussing the design ideas of the engine,we also introduced the implementation techniques including the objects mapping and matching method,the algorithm of weighted objects similarity calculation,and the indexes construction,etc. The engine implements the search and positioning based on website contents and the attachment contents of Word and pdf. Experimental results showed that the search engine had high accuracy and recall rate. The engine could also serve the supports to content search and personalised services for corporate websites.更多还原
