Embodiment Construction
[0021] The present invention will be further described below in conjunction with drawings and embodiments.
[0022] The links where the present invention is located are as figure 1 As shown in , it is an intermediate link between input query and query submission, and the user input is analyzed and processed before being submitted to the index system. When the user enters the query words, if the user's input is wrong, the relevant products will not be returned. At this time, it is necessary to correct the user's input and provide the product closest to the user's intention. At the same time, it is necessary to expand the user's query words, make relevant search recommendations, and help users quickly find the products they need. That is to say, for various unknown inputs from users, we cannot hand them over to the query system for processing immediately. First of all, we need to preprocess various input from users, so that we can search better.

The invention provides a method for error correction and expansion of an electronic commerce search engine. The method comprises the steps that (1) in the initialization process, all kinds of mapping tables are prepared, wherein the mapping tables comprise a correct word table and an expansion word table, all mapping table files are loaded and analyzed, and a relevant data structure and a relevant dictionary are established; (2) input data are received and preprocessed, wherein preprocessing comprises conversion between a simplified style and a traditional style and blank removal; (3) after preprocessing is completed, the expansion word table is queried directly, and a result is fed back directly if a relevant expansion word exists in the expansion word table; (4) if a relevant expansion word is not found in the expansion word table, the input data are segmented, English error correction and Chinese error correction are conducted respectively, the expansion word table is queried again according to an error correction result after error correction is completed, and then a result is output. The method for error correction and expansion of the electronic commerce search engine has the advantages that the electronic commerce search engine is optimized, error correction and expansion can be conducted on the data input by a user, the user experience is improved, and the recall rate of products is increased.
Description
technical field [0001] The invention relates to the optimization of an e-commerce search engine, in particular to an error correction and expansion method for an e-commerce search engine. Background technique [0002] The search engine system consists of a download system, an analysis system, an index system, and a retrieval system. [0003] Download system: For search engines such as Baidu, it mainly crawls web pages from major Internet sites. For e-commerce websites, there is no need to download the system, and the pages to be retrieved are all product description pages stored locally. [0004] Analysis system: Preprocessing the content of the webpage (traditional to simplified, uppercase to lowercase, full-width to half-width), word segmentation, word stem extraction, stop word removal, etc. [0005] Indexing system: Corresponding to the index terminal, call the word segmentation service, cut the warename (commodity name) of each commodity into terms, and create a posti...
