ContextKT: A Context-Based Method for Knowledge Tracing

نویسندگان

چکیده

Knowledge tracing, which is used to predict students’ performance based on their previous practices, has attracted many researchers’ attention. Especially in this rising period of intelligent education, knowledge tracing methods have been developed. However, most the existing focus personality practices and concepts but ignore contexts related studying process. In paper, we propose a context-based model, combines historical during mastery. To be specific, first define five for prediction. The basic context current state student, described by practice sequences. Then, QR-matrix defined represent relationship among questions, concepts, responses, describes questions knowledge. Furthermore, an improved LSTM model proposed capture memory forgetness, multi-head attention mechanism designed behaviors. Finally, captured contexts, prediction ContextKT established. Our evaluated two real educational datasets. experimental results show our effective efficient student prediction, it outperforms other methods.

A knowledge-based system approach for a context-aware system

Knowledge-based systems (KBS) are advanced systems for representing complex problems. Their architecture and representation formalisms are the groundwork of today’s systems. The knowledge is usually derived from expertise in specific areas and has to be validated according to a different methodology than is used in conventional systems because the knowledge is symbolic. This paper describes the...

Reasoning about Models of Context. A Context-Oriented Logical Language for Knowledge-Based Context-Aware Applications

Ontologies have been suggested as a means to ensure interoperability of Ambient Intelligence (AmI) applications as well as effectiveness within different sensory environments. We introduce a new logical language specifically tailored to the task of ontology design for AmI applications. This language has known advantages of description logics, namely a precisely defined semantics and a brief, in...
