Embodiment Construction

[0030] In the following, the present invention will be further explained in conjunction with the accompanying drawings and specific implementation examples, in order to understand its module composition and operation process more clearly, but this cannot limit the protection scope of the present invention.

[0031] Such as figure 1 as shown, figure 1 It is an organization chart of a text data analysis and statistics system based on natural language processing in the present invention. The text data analysis and statistics system based on natural language processing includes a natural language information extraction subsystem, a knowledge map management subsystem, and a data Analysis subsystem and data visualization subsystem, the four subsystems are in charge of different functions.

[0032] The above-mentioned natural language information extraction subsystem includes a corpus preprocessing module and a knowledge extraction module, and the corpus preprocessing module is used...

Abstract

The invention discloses a text data statistical analysis system based on natural language processing. The system comprises a natural language information extraction subsystem, a knowledge graph management subsystem, a data analysis subsystem and a chart visualization subsystem. The natural language information extraction subsystem comprises a corpus preprocessing module and a knowledge extractionmodule. The knowledge graph management subsystem comprises an ontology construction module and a data configuration module; the data analysis subsystem comprises a problem understanding module, a graph query calculation module and a semantic matching module, and the data visualization subsystem is used for generating and visually displaying a data graph. The invention further provides a data statistical analysis method based on natural language processing. According to the method, a knowledge base is established by utilizing the natural language processing technology and the knowledge graph technology, then text data statistical analysis is realized through the intelligent data analysis and visualization technology, and a text document data analysis result is automatically generated into achart to be visually displayed, so enterprise production and operation are guided.

Description

technical field [0001] The invention relates to a text data statistical analysis system and method based on natural language processing, belonging to the technical field of artificial intelligence. Background technique [0002] In the process of production and operation of an enterprise, there are a large number of text documents carried in the form of natural language, such as technical reports, inspection records, operation logs, etc. The text documents contain a wealth of key data information. Taking the maintenance reports of power plants over the years as an example, "How many types of equipment are mentioned in the report?" How does the time change”, etc., but most of the above-mentioned text data information is not directly counted into digital form, but exists in text form, such as “This maintenance equipment includes steam turbines, boilers, generators”, so in this example The statistical result of the total number of overhauled equipment is 3. Mining similar text ...
