Embodiment 1

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

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

[0088] S2: Using the precise attributes to extract the fuzzy attributes of the knowledge points in the digital resources to be processed;

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

[0090] The precise attributes of the above knowledge points are the data describing the specific attributes of the knowledge points. For different types of knowledge points, the contents of the precise attributes are different. For example, the precise attributes of the knowledge points of historical figures include name, gen...

Embodiment 2

[0171] This embodiment provides a device for extracting sentence groups based on target knowledge points, such as Figure 5 shown, including:

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

[0173] Fuzzy attribute extraction unit U2: used to extract fuzzy attributes of knowledge points in 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 groups in the digital resources to be processed by using precise attributes and fuzzy attributes to obtain knowledge point sentence groups.

[0175] The sentence group extraction device based on target knowledge points provided in this embodiment improves the accuracy of sentence group extraction of knowledge points by adding precise attributes and fuzzy attributes of knowledge points.

[0176] Specifically, as Figure 6 As shown, the fuzzy attribute extraction unit ...

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 popular research field at present, and extracting information related to knowledge points 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 units of sentences are very scarce. The sentence group connection of knowledge points realizes the knowledge fragment resources organized in units of sentences. The sentence group linking of knowledge points is to extract the sentences related to knowledge points contained in the corpus one by one to form knowledge fragments through content analysis and processing of corpus. A sentence group, also called a sentence gro...
