Abstract

The invention provides a knowledge graph construction method and system suitable for scientific and technological literature, a terminal and a medium. The knowledge graph construction method and system are used for constructing a corresponding knowledge graph suitable for the scientific and technological literature according to specific source data. The technical scheme provided by the invention has extremely high integrating degree with unstructured text characteristics of scientific and technical documents; The word segmentation unit is improved by combining words and manual verification, extraction of professional coincidence words in scientific and technical literatures is facilitated, a seed knowledge base is automatically extracted through encyclopedia, and therefore a large amount of cost for manually maintaining the seed knowledge base at the initial stage is saved.

Description

technical field [0001] The present invention relates to the field of knowledge map construction, in particular to a knowledge map construction method, system, terminal and medium suitable for scientific and technological documents. Background technique [0002] Knowledge map is a series of different graphs showing knowledge development process and structural relationship. Using visualization technology to describe knowledge resources and their carriers, mining, analyzing, constructing, drawing and displaying knowledge and their interrelationships is a kind of Using visualization technology to describe the semantic network of knowledge resources and their carriers, the formed semantic network can be used to solve problems in the field of artificial intelligence such as precise search, calculation of text semantic similarity, production of dialogue robots or intelligent question answering systems. In recent years, with the development of new-generation machine learning technol...
