Searching method and equipment

Abstract

The invention discloses a searching method and searching equipment. The searching method comprises the following steps: receiving a search keyword input by a user, acquiring at least one search document relating to the search keyword based on the search keyword, and determining the semantic vector of the search keyword; according to the semantic vector of the search keyword and the semantic vector of each search document, calculating the semantic correlation between each search document and the search keyword; according to the semantic correlation, sequencing the search documents and outputting the search documents to the user according to the sequencing result. The semantic vector of the document of a search engine is acquired according to the semantic vector of a document tile, the semantic vector of a document identifier and the semantic vector of a document category, so that the semantic information of the document can be expressed accurately, the precision of the semantic correlation between the document acquired by calculation and the search keyword is improved, the search precision of the search engine is improved, and the user experience on the search engine is improved.

Description

technical field [0001] The present application relates to the technical field of Internet information search, in particular to a search method and device. Background technique [0002] The level of correlation is an important factor used to characterize the search accuracy of the search engine, and is also one of the important factors affecting the user's satisfaction with the search results fed back by the search engine. [0003] At present, when a search engine receives a query request sent by a user, it judges whether the keywords contained in the query request are related to the subject of the document contained in the index library, and then outputs and displays the relevant documents as search results to the user. . [0004] In the prior art, the way of judging whether the keyword contained in the query request is related to the subject of the document contained in the index database generally uses a topic model method based on the bag of words method. The specific m...
