Embodiment

[0129] The real question and answer scene is designed and built a multi-group test data, the accuracy of the test template matching algorithm, as shown in Table 3. The first group and the second set of test data come from the true want to ask the question and answer system, and the third group and the fourth group of data are derived from the front climb to know the relevant problem, in which the third group About 50% is a single subject entity question, and about 70% of the fourth group is a single topic or a double subject entity question.

Abstract

The invention discloses a programming education knowledge graph construction, completion and intelligent question and answer method, which comprises the following steps of: a) processing programming domain knowledge, constructing a semi-automatic identification entity tool by combining BiLSTM-CRF with an artificially constructed knowledge point term dictionary, and assisting in artificially constructing a programming domain knowledge graph by means of the tool; b) discovering a part, which needs to be complemented, of the knowledge graph through a knowledge graph quality evaluation algorithm based on node centrality discrimination, and complementing the knowledge graph by using a direct perfection or crowdsourcing mode; and c) establishing a programming education field intelligent question-answering system based on the programming field knowledge graph. Compared with a traditional related method, the intelligent question-answering system in the programming education field is completed by means of the constructed knowledge graph in the programming education field. The practical problem that the knowledge graph is applied to the question and answer system from construction to completion is solved.

Description

Technical field [0001] The invention belongs to the field of computer science, and specifically, a method of programming education knowledge map construction, complement and intelligence question and answer. Background technique [0002] Knowledge maps use intelligent, efficient organizational knowledge methods, enabling relevant applications to accurately query the information you need, providing new ideas, comprehensive knowledge maps, and attribute, etc., can provide data mining, question and answer system Supporting, knowledge maps have become one of the core driving forces that promote the development of artificial intelligence. In recent years, with the development of knowledge map technology, the focus of knowledge map application and research gradually turned from open domain knowledge map to the domain knowledge map, the knowledge map and depth integration of various industries have become trend. Domain knowledge maps have stronger targeted and professionalism due to its...
