Problems solved by technology

Such a matching query method can only show users the content including the user's query keywords. For highly specialized vertical fields, the richness of query results is low, and there are fewer knowledge dimensions for related search recommendations.

Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] see figure 1 , figure 1 The overview illustrates a schematic flowchart of a concept processing method for a vertical field according to an embodiment of the present invention, and the method may include:

[0041] S101, determine the category of the vertical field to which the user's search sentence belongs,

[0042] S102. Determine the concept expression of the search sentence, and determine the position information of the concept expression in its vertical field category according to the distance between the concept expression and the collection of one or more knowledge system concepts pointed to by the concept expression,

[0043] S103, expand the concept expression of the search sentence according to the coherence of the sentence a...

Abstract

The invention provides a concept processing method and device for a vertical field. The method can comprises the following steps of judging a vertical field type to which a search sentence of a user belongs, confirming a concept expression of the search sentence, confirming position information of the concept expression in the vertical field type according to the distance between the concept expression and one or more knowledge system concept sets directed by the concept expression, and extending the concept expression of the search sentence according to the continuity of the sentence and the position information. Through applying the method and the device, the richness of searching results is improved, and the searching of relevant knowledge dimensionality can be recommended conveniently.

Description

technical field [0001] The present invention relates to the field of data search, and more specifically, to a concept processing method and device for vertical fields. Background technique [0002] Vertical fields are relative to general fields, and mainly refer to non-comprehensive, professional and in-depth subdivisions of a specific field. Non-standardized consumer goods fields such as education, special sales, and medical care are all vertical fields. Each vertical field includes its corresponding set of concepts. For example, the medical vertical field may include concepts such as diabetes, internal medicine, penicillin, and people's hospital. [0003] For data retrieval in the vertical field, at present, it is mainly performed by matching the user's query keywords with strings, and related searches recommended to users are mainly performed by finding high-frequency sentences similar to the user's query keywords. Such a matching query method can only show users the con...
