Problems solved by technology

[0003] However, for the words in the user query string, the existing technology can only distinguish the importance according to the IDF value, but does not understand the components it represents, especially the scenic spot components in this type of query string, whose IDF value is not necessarily high. But it is the most critical part of the query string. Therefore, the existing technology cannot accurately give the sorting of the retrieval results expected by the user, and the user experience is poor.

Abstract

The present invention provides a retrieval result sorting method based on scenic spot component identification, which includes obtaining a query string; performing word segmentation processing on the acquired query string; identifying scenic spot components in the query string after word segmentation processing; and performing retrieval Recall, and perform scoring and sorting processing on the retrieval results containing scenic spots. The invention also provides a retrieval result sorting device and a user terminal based on scenic spot component identification. The retrieval result sorting method, device, and user terminal based on scenic spot component identification provided by the present invention can accurately provide the sorting of search results expected by the user through the recognition of scenic spot components, and the user experience is good.

Description

technical field [0001] The present invention relates to the technical field of computer communication, in particular to a method, device and user terminal for sorting search results based on scenic spot component recognition. Background technique [0002] Most of the existing tourism retrieval is based on text keyword matching to achieve the user's acquisition of tourism information. In terms of specific text relevance ranking, it is basically to give different weights to the title and text content of the tourist information document, and then according to the matching situation of the user query word on the title and text and the inverse text frequency index (Inverse Document Frequency, IDF) of the query word ) weight for weighted scoring, and then sort the retrieval results according to this score. [0003] However, for the words in the user query string, the existing technology can only distinguish the importance according to the IDF value, but does not understand the co...
