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 objectives, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See figure 1 , figure 1 The outline illustrates a schematic flow diagram of a concept processing method for a vertical field according to an embodiment of the present invention. The method may include:

[0041] S101: Determine the vertical domain category to which the user's search sentence belongs,

[0042] S102: Determine the conceptual expression of the search sentence, and determine the position information of the conceptual expression in the vertical domain category to which it belongs according to the distance between the conceptual expression and the set of one or more knowledge system concepts to which the conceptual expression points.

[0043] S103: Expand the conceptual expression of the search sentence according to the coherence of t...

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] The vertical field is relative to the general field. It mainly refers to the non-comprehensive, professional and in-depth subdivision of a specific field. Non-standard consumer goods fields such as education, sale, 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, currently it is mainly carried out by matching the user's query keyword with a string, and the related search recommended to the user is mainly performed by finding high-frequency sentences similar to the user's query keyword. Such a matching query method can only show users the content incl...
