specific Embodiment

[0088] The embodiment of the present invention provides a method for constructing a knowledge map based on semantic extraction of paraphrased sentences, which mainly includes four stages, one is the construction of a term paraphrase database; the other is the extraction of knowledge units based on shallow analysis of sentence chunks; The third is the storage of the knowledge unit library, that is, the construction of the knowledge unit library, and the fourth is the visual display of the knowledge graph. It mainly includes the following steps:

[0089] Step A, extract and fuse the meanings of scientific and technological corpus from multiple sources, and construct a term meaning library with high credibility and knowledge content. Paraphrase extraction adopts a combination of syntactic analysis and semantic analysis. The process of paraphrase extraction can be as follows: figure 2 shown.

[0090] Specifically include the following steps:

[0091] Step A01: Take the sentence ...

Abstract

The invention discloses a method for dynamic construction of a professional field mapping knowledge domain based on term paraphrase knowledge units and relates to the field of computer information management and information processing. The method is characterized in that a natural knowledge processing technology is used to extract and update knowledge units automatically from a real text; real contents of professional knowledge can be reflected by finer granularity contents; dynamic updating and management can be achieved; traditional problems such as insufficient timeliness, excessive subjectivity and difficult updating and maintenance caused by pure dependence on manual judgment could be solved; and a better technological manner can be provided for construction of a large knowledge library in professional fields. In addition, a mesh-shaped topological structure is adopted, so correlation between the knowledge units is closer, and semantic dimensions become diversified; a visualized knowledge map manner is used for visualized display, so a good knowledge foundation can be laid for automatic finding, inference and computation of knowledge; and the method can support engineering application effectively.

Description

technical field [0001] The invention relates to the field of computer information management and information processing, in particular to a method for dynamically constructing a knowledge graph in a professional field based on term interpretation knowledge units. Background technique [0002] Knowledge units, also known as "knowledge genes" and "knowledge elements", are used to reveal the specific knowledge contained in professional terms, and represent, organize, reason and serve knowledge with finer granularity and dimensions. Traditionally, experts generally rely on the wisdom of experts to summarize and extract knowledge units manually. Although it is more precise, the efficiency is relatively low and the update is relatively slow; some studies also use stop word technology and statistical models, using high-frequency words as Knowledge units improve the efficiency of knowledge unit discovery to a certain extent, but due to the separation of contextual semantic analysis,...
