Embodiment 1

[0086] This embodiment provides a method for extracting sentence groups based on target knowledge points, such as figure 1 As shown, including the following steps:

[0087] S1: To obtain the precise attributes of the knowledge point, its length is generally required to be greater than or equal to 2 and less than or equal to 10;

[0088] S2: Use precise attributes to extract fuzzy attributes of knowledge points from digital resources to be processed;

[0089] S3: Use precise attributes and fuzzy attributes to link the sentence groups of knowledge points in the digital resources to be processed to obtain the sentence groups of knowledge points.

[0090] The precise attributes of the above knowledge points are data that describe the specific attributes of the knowledge points. For different types of knowledge points, the precise attributes include different content. For example, the precise attributes of the knowledge points of historical figures include name, gender, dynasty, Date of bi...

Embodiment 2

[0171] This embodiment provides a sentence group extraction device based on target knowledge points, such as Figure 5 Shown, including:

[0172] Accurate attribute acquisition unit U1: used to obtain the precise attributes of knowledge points;

[0173] Fuzzy attribute extraction unit U2: used to extract fuzzy attributes of knowledge points from digital resources to be processed by using precise attributes;

[0174] The knowledge point sentence group acquisition unit U3 is used to link the knowledge point sentence group in the digital resource to be processed by using the precise attribute and the fuzzy attribute to obtain the knowledge point sentence group.

[0175] The device for extracting a sentence group based on a target knowledge point provided by this embodiment improves the accuracy of extracting a sentence group of a knowledge point by adding the precise attribute and fuzzy attribute of the knowledge point.

[0176] Specifically, such as Image 6 As shown, the fuzzy attribute ...

Abstract

The invention relates to a sentence cluster extract method and device based on object knowledge points; the method comprises the following steps: obtaining knowledge point accuracy attributes; using the accuracy attribute to extract attribute of the knowledge point from to-be processed digit resources; using the accuracy attribute and fuzzy attribute to do sentence cluster hitching of the knowledge points in the to-be processed digit resources; obtaining the knowledge point sentence cluster. The accuracy attribute and fuzzy attribute of the knowledge points are added so as to improve knowledge point sentence cluster extract accuracy.

Description

Technical field [0001] The invention relates to the field of digital resource processing, in particular to a method and device for extracting sentence groups based on target knowledge points. Background technique [0002] Natural language processing is a hot research field at present, and extracting knowledge points related information from a large amount of text corpus is a research hotspot in natural language processing. At present, the knowledge resources stored in the form of chapters are very rich, but the knowledge fragment resources organized in sentence units are very scarce. The sentence group linking of knowledge points realizes the knowledge fragment resources organized in sentence units. The sentence group linking of knowledge points is through the content analysis and processing of the corpus, and the sentences related to the knowledge points contained in the corpus are extracted one by one to form knowledge fragments. Sentence group, also called sentence group, is ...
