Abstract

The invention discloses a data processing method based on a knowledge map, which comprises the following steps: constructing a knowledge map based on the sorting of examination questions and teachingand research knowledge, school teaching, teaching materials and the difficulty degree of examination questions to obtain a knowledge base; setting search conditions and extracting test questions according to the search conditions, wherein, when the search conditions contain natural language, the search conditions are converted into structured search instructions including knowledge points and search ranges, and the search instructions are matched with the contents in the knowledge map to search out the test questions; carrying out similarity algorithm, sorting algorithm and comprehensive screening algorithm on the searched test questions to obtain a screening result; pushing the filter results to the user. The invention simplifies the retrieval process of the test questions and improves the efficiency of searching the test questions by establishing the knowledge map of the test questions and searching based on the knowledge points when searching.

Description

technical field [0001] The present invention relates to the technical field of information search, and more specifically, to a data processing method based on a knowledge map. Background technique [0002] Knowledge graph, also known as scientific knowledge graph, is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. Resources and their carriers, mining, analyzing, constructing, mapping and displaying knowledge and their interconnections. [0003] By combining the theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with metrology citation analysis, co-occurrence analysis and other methods, and using visual maps to vividly display the core structure, development history, and frontiers of disciplines It is a modern theory that achieves the purpose of multidisciplinary integration through domain and overall knowledge structure. Provide...
