Problems solved by technology

[0006] The purpose of the present invention is to solve the technical problems of manual collection, screening and report generation difficulties in the field of scientific and technological information, and creatively propose an automatic scientific and technological information summary generation method that runs through data collection, data screening and intelligence generation
This method effectively solves the problem that the generation of scientific and technological intelligence has high requirements for data timeliness and authority in the process of data screening, and the problem that the traditional neural network-based multi-document generation method cannot be applied due to the lack of data sets in the field of scientific and technological intelligence.

Embodiment

[0121] This embodiment describes a specific embodiment of the method of the present invention.

[0122] The implementation diagram is as follows figure 1 The overall process is shown. The invention provides a complete process from text data acquisition, data processing, and abstract text generation in the process of generating scientific and technological information abstracts. During the specific implementation of the present invention, firstly, the theme crawler module starts to work, obtains the data required for analysis according to the keyword library provided by the user, then the text information value evaluation module analyzes and sorts the obtained data, and finally uses the sorting result as The input of the summary generation module is brought into the model to get the final result.

[0123] First, according to the keywords provided by the user, the topic crawler module is used to obtain data in Google Scholar, DARPA, IARPA, and RAND Think Tank. figure 2 It is...

Abstract

The invention relates to an unsupervised scientific and technological intelligence abstract automatic generation method based on multi-sentence compression, and belongs to the technical field of natural language generation. Aiming at multi-document text generation in the field of science and technology intelligence, firstly, source data are acquired based on a topic crawler of an LDA topic similarity word library extension method; and sorting all text paragraphs through a text information value evaluation model of three indexes of authority, timeliness and content correlation of the text information. And selecting a paragraph with a higher score as an original text for generating the final science and technology intelligence. Finally, an unsupervised multi-document abstract method based on spectral clustering and multi-sentence compression is adopted, and a science and technology intelligence abstract is automatically generated. According to the method, the problem that in the data screening process, scientific and technological information generation has high requirements for data timeliness and authority is effectively solved, and the problem that a traditional multi-document generation method based on a neural network cannot be applied due to lack of a data set in the field of scientific and technological information is effectively solved.

Description
