Problems solved by technology

[0005] The above processing method cannot detect all the knowledge data with conflicting information in the knowledge base, but only a small part of the knowledge data with errors can be detected, and there are still a large number of conflicting knowledge data in the knowledge base, so that the knowledge base The accuracy of the knowledge data in the middle is low

Embodiment 1

[0027] figure 1 It is a flow chart of the knowledge data processing method provided by the embodiment of the present invention. by including as image 3 The computer system of the shown device executes the processing method.

[0028] Such as figure 1 As shown, in step S110, the knowledge data to be detected is acquired.

[0029] Wherein, the knowledge data may be one sentence or multiple sentences in the knowledge base. For example, Shijiazhuang City is located in the south-central part of Hebei Province and is the capital of Hebei Province. The knowledge base can be composed of multiple knowledge sources, for example, Baidu Encyclopedia, Wikipedia and news websites, etc.

[0030] Specifically, since the knowledge base is composed of multiple knowledge sources, the knowledge data of the same topic from different knowledge sources may be true or false. In order to provide correct query results for users who inquire about the corresponding knowledge information, knowledge T...

Embodiment 2

[0039] figure 2 It is a flow chart of another embodiment of the knowledge data processing method provided by the present invention, and the embodiment can be regarded as figure 1 Another specific implementation scheme of .

[0040] Such as figure 2 As shown, in step S210, the knowledge data to be detected is acquired.

[0041] Wherein, the step content of step S210 is the same as the step content of step S110 in the first embodiment above, and will not be repeated here.

[0042] In step S220, data of subjects, predicates and objects are extracted from the knowledge data to be tested to obtain corresponding first structured knowledge data.

[0043] Wherein, the step content of step S220 is the same as the step content of step S120 in the first embodiment above, and will not be repeated here.

[0044] In step S230, analyze the attribute information of the subject and / or object in the first structured knowledge data according to the preset attribute constraint detection rul...

Embodiment 3

[0062] Based on the same technical concept, the embodiment of the present invention also provides a knowledge data processing device. Such as image 3 As shown, the processing device includes a knowledge data acquisition module 310 , a structured knowledge acquisition module 320 and an information conflict determination module 330 .

[0063] The knowledge data acquiring module 310 is used to acquire the knowledge data to be detected;

[0064] The structured knowledge acquisition module 320 is used to extract the data of the subject, predicate and object from the knowledge data to be detected, and obtain the corresponding first structured knowledge data;

[0065] The information conflict determination module 330 is used to compare the first structured knowledge data with the existing second structured knowledge data according to the preset knowledge conflict detection rules, and determine whether the knowledge data to be detected is consistent with the There are information c...

Abstract

The embodiments of the present invention disclose a knowledge data processing method and apparatus. The processing method comprises: acquiring to-be-detected knowledge data; extracting data of a subject, a predicate and an object from the to-be-detected knowledge data to obtain corresponding first structural knowledge data; and according to a preset knowledge conflict detection rule, comparing the first structural knowledge data with existing second structural knowledge data, and determining whether the to-be-detected knowledge data has an information conflict with the existing knowledge data. With adoption of the method and the apparatus, which are disclosed by the embodiments of the present invention, it is convenient to further determine correctness of the knowledge data with the information conflict subsequently so as to improve accuracy of the knowledge data in a knowledge base.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for processing knowledge data. Background technique [0002] With the development of network technology, the Internet has become one of the important means for people to acquire knowledge, and the knowledge base based on the Internet has emerged as the times require. Since the knowledge base of the Internet is usually composed of multiple knowledge data sources, and the knowledge data of the same knowledge topic in different knowledge data sources may be different, or even conflict or error with each other, therefore, the use of knowledge in multiple knowledge data sources When building a knowledge base from data, it is necessary to detect the knowledge data in it. [0003] Generally, knowledge data can be detected using simpler attribute constraint rules, that is, to compare the attribute information (such as gender, age, etc.) of the subject and / or object...
