Abstract: Procedural knowledge plays an important role in the process of human learning and cognition. In the past, the organization of procedural knowledge was realized through a production system, which is a non-semantic method that can not reflect the relationship between knowledge and is difficult to maintain. Combining ACT-R theory, event cognition theory and event models in the literature, a seven-tuple semantic model of events that can represent procedural knowledge is proposed. Taking the procedural knowledge in the Java language as an example, a procedural knowledge event ontology model is constructed, and an ACT-R ( Adaptive Control of Thought-Rational) cognitive model based on the procedural knowledge event is designed. The procedural knowledge event ontology can realize the semantic complete description of the procedural knowledge and the relationship between them, providing new ideas for the organization of procedural knowledge teaching resources and the network teaching based on procedural knowledge.

Key words: procedural knowledge； , adaptive control of thought-rational ( ACT-R) theory； , event cognition； , event； , event ontology
