Event Graph Construction Based on Disciplinary Procedural Knowledge: Concept Model and Application
Yao Xiao, Zehui Zhan, Man Yuan · 2022
Abstract: At present, procedural knowledge is mainly represented by production rules. Although this representation is concise, problems exist on lack of semantic elements and single semantic relationship, which is not conducive to the representation of procedural knowledge and hinders the teaching and application of procedural knowledge. Therefore, this paper firstly analyzes the semantic elements that procedural knowledge should have, and the lack of time and space elements in traditional representation methods. Combining with the cognitive background of procedural knowledge and introducing event cognition, the representation method of procedural knowledge graph and the construction process model are obtained. The verification proves that the event graph is a procedural knowledge representation method with complete semantic roles and rich semantic relations.
