Embodiment

[0068] This embodiment provides a method for constructing a knowledge graph, the method comprising:

[0069] Step S1: Obtain a corpus;

[0070] Step S2: Preprocessing the corpus;

[0071] Step S3: converting the corpus and storing it in the database;

[0072] Step S4: Build a knowledge map according to the database.

[0073] figure 1 It is the system requirement diagram of the present invention, as shown in the figure, at first, obtain the corresponding step S1 of text data: obtain the corpus, the specific acquisition method is: select the target webpage from the Internet, define the webpage as document format, and convert all the data into Text, and then traverse the webpage converted into text to obtain all the text data in it, and finally create an element group set element to store all the text data obtained. The webpage converted into text not only includes text content, but also includes HTML tags, annotations, etc., and tags include information such as text styles. ...

Abstract

The invention relates to the technical field of natural language processing, in particular to a knowledge graph construction method which includes the steps: S1, acquiring a corpus set; S2, preprocessing the corpus set; S3, converting a corpus set and storing the corpus set into a database; and S4, constructing a knowledge graph according to the database. Compared with an existing knowledge graphconstruction method, the knowledge graph construction method has the advantage that the quality of the constructed knowledge graph is higher.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, and more specifically, to a method for constructing a knowledge map. Background technique [0002] Natural language refers to Chinese, English, French and other languages ​​that people use every day. It is a language that naturally evolves with the development of human society, rather than a man-made language. It is an important tool for human learning and life. In a nutshell, natural language refers to the language established by human society, which is different from artificial language, such as programming language. [0003] Natural language processing (NLP) refers to the use of computers to process information such as shape, sound, and meaning of natural language, that is, input, output, recognition, analysis, understanding, and generation of words, words, sentences, and texts. etc. operation and processing. Specific manifestations of natural language processing ...
