Embodiment Construction

[0081] The present invention will be further described below in conjunction with a specific embodiment of a conversational intelligent teaching system about computer basic knowledge, but the protection scope of the present invention is not limited to the following embodiments.

[0082] A conversational intelligent teaching system, such as figure 1 As shown, it includes interconnected knowledge base unit and functional unit. The functional unit includes input preprocessing module, answer reasoning module, evaluation module and dialogue management module, and the input preprocessing module, answer reasoning module, evaluation module and dialogue management module. They are connected to each other; among them, the knowledge base unit includes domain ontology, interactive template, semantic dictionary and student model; the preprocessing module is used for word segmentation, part-of-speech tagging, ontology element tagging and classification of the content input by students; the an...

Abstract

The invention discloses a conversational intelligent teaching system, which includes a knowledge base unit and a functional unit connected to each other, the functional unit includes an input preprocessing module, an answer reasoning module, an evaluation module and a dialog management module, and the input preprocessing module , the answer reasoning module, the evaluation module and the dialogue management module are connected to each other; wherein, the knowledge base unit includes a domain ontology, an interactive template, a semantic dictionary and a student model. The conversational teaching system of the present invention uses a domain ontology with good semantic relationship and hierarchical structure to model the domain knowledge of the system, and can provide reasoning-based knowledge for the system through the conceptual hierarchical structure and semantic relationship, and proposes an ontology The driver-driven dialogue management mechanism can quickly form dialogue content and dialogue sequences.

Description

technical field [0001] The invention relates to the technical field of teaching, in particular to a conversational intelligent teaching system. Background technique [0002] Conversational teaching system is a subset of intelligent teaching system, which uses constructivism as its theoretical basis, imitates natural language dialogue in human tutoring, and encourages learners to construct knowledge instead of just receiving it. Traditional conversational teaching systems generally employ large text corpora called course scripts as domain knowledge models. Since text corpus is student-oriented knowledge and cannot be understood by machines, domain knowledge models based on text corpus cannot provide reasoning-based knowledge for intelligent teaching. [0003] Ontology, which originated from philosophy, has been widely used in the information field in recent years, especially the application of ontology on the Web has led to the birth of the Semantic Web. Ontology is a consi...
