A Knowledge-Based Model for Designing the Knowledge Querying System in Education

The knowledge querying is an important function in educational intelligent systems. This function can support the learner who want to study and learn easily at home or anywhere without teachers. Designing the knowledge querying systems that can support the near natural query language for users in studying are extremely necessary. In this paper, a model of knowledge representation for designing the knowledge querying system and the structured query language on knowledge based (KSQL) are presented. Besides that, the handling techniques on KSQL and algorithms for solving the problems on model that have studied. Results of the paper have been applied to construct knowledge querying system for the knowledge of High-School Mathematics and Data Structures and Algorithms domains. Especially, the knowledge querying system on High-School Mathematics has archived the third prize: 16th Vietnam Fund for Scientific and Technological Creations (VIFOTEC) Award, 2021.
