Embodiment Construction

[0054]In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] When searching, the user will input a search sentence according to the need. Generally speaking, a search sentence is composed of several search words. In view of the richness and complexity of the Chinese language, the sentences entered by the user for retrieval are various. In order to specify their needs in detail, they do not hesitate to use words. But in fact, many words can be used as auxiliary analysis words to make the meaning of expression more clear, but they have little practical significance for retrieval. In the embodiment of the pre...

Abstract

The invention relates to the field of information retrieval and provides a processing method for retrieving sentences by a user. The method comprises the following steps: establishing a sample database which is related to a word which is retrieved by the user and a resource database which is related to the word which is retrieved by the user; performing feature extraction on the word which is retrieved by the user; classifying the word, which is retrieved by the user, by virtue of a classifier and performing basic empowerment on the word which is retrieved by the user; after the basic empowerment, performing entity power call on the word which is retrieved by the user; and outputting the weight of the word which is retrieved by the user. The invention also provides a processing system for retrieving sentences by the user. By adopting the technical scheme of the invention, the accuracy of entity extraction is ensured, the dynamic weight is obtained and the problem that the weight is constant and unreasonable if only words which are counted offline are inquired is solved. Finally, the weight of the word which is retrieved by the user is further optimized by subordination identification, the weight of the core word which is retrieved by the user is highlighted and a practical and reasonable information support is provided for search engines.

Description

technical field [0001] The invention relates to the field of information retrieval, in particular to a method and system for processing user retrieval sentences. Background technique [0002] Search sentence analysis is the basis of search engine. The search engine searches based on the user's search statement, but often the returned search results are not relevant, and only hit part of the words in the user's search statement. The main reason is that the vocabulary in the user's search sentence has no reasonable weight, so that the core and relatively important words are not proposed in the search. [0003] In advertisement retrieval, relevant advertisement recommendation information will be given at a certain position according to the user's retrieval sentence. However, it is often found that the advertisements displayed by the retrieval system are not very relevant to the information entered by the user, or even irrelevant. The advertisement words only hit part of the w...
