E-commerce search scoring and ranking method and system

Abstract

The invention provides an e-commerce search scoring and ranking method. The method includes the steps of 1 building a keyword lexicon of e-commerce platform commodities, 2 calculating net scores of significance factors of the commodities, 3 extracting attribute information in the commodities and storing the attribute information into indexes, 4 building series query blocks according to relevance and significance, 5 selecting corresponding search results according to paging parameters and conducting ranking. According to the e-commerce search scoring and ranking method, according to the characteristics of e-commerce search, central keywords of the commodities are recognized, and preferential matching is executed during query; after query and search keywords input by a user are received, semantic analysis is conducted, and query statements of different relevance and significance are built due to the fact that query domains are different and indexes such as commodity page view are different. When the user searches for commodities, different queries are executed according to difference of query relevance and significance, and therefore search results are returned rapidly.

Background technique [0002] With the rapid development of e-commerce, the number of commodities on the e-commerce platform has increased sharply. If buyers want to find the desired commodities from the massive information, they must rely on a highly accurate search system. [0003] Usually, e-commerce search engines have many ranking factors and complex query statements. If the global calculation involves a large amount of data, the ranking process will consume a lot of resources and the response time will be slow. Moreover, due to the large number of ranking factors, the score calculation standards are not uniform. When performing complex calculations on the ranking factors, one consequence is that t...
