Problems solved by technology

[0003] A set of rich situational simulation dialogue teaching materials must include multi-path conversation teaching materials. At present, such teaching materials need to be compiled manually in advance, and the expansion of teaching materials also needs to rely on a large number of manual classification processing, making expansion difficult.

Embodiment Construction

[0031] figure 1 A learning material expansion system 100 according to an embodiment of the present invention is shown. In the embodiment, the learning material expansion system 100 is a language learning material expansion system. Such as figure 1 As shown, the learning material expansion system 100 at least includes a database 110, a content similarity calculation module 120, a structure similarity calculation module 130, a theme similarity calculation module 140, a reliability calculation module 150, an automatic expansion module 160, and a display unit 170. Wherein, the conversation database 110 may contain multiple topics and topic-related structure information, each topic has a corresponding topic category (or called a topic sentence unit group) (sentence category), and each topic category includes at least one sentence unit (for example, conversation sentence). ), topic title (topic), role. Each topic category contains a group of topic sentence units of the same topic, a...

Abstract

The invention provides a method for automatically expanding teaching materials, which is suitable for a system for expanding teaching materials and used for expanding and inputting teaching material data to a database, wherein input teaching material data are at least provided with a sentence unit; the database comprises at least one subject and structure information relevant to the subject; and the subject corresponds to subject classification which comprises at least one corresponding subject sentence unit. The method comprises the following steps of: firstly, calculating the subject similarity estimated value of the sentence unit in the input teaching material data, which corresponds to the subject in the database, wherein the subject similarity estimated value comprises the content similarity estimated value and the structure similarity estimated value relevant to the subject; secondly, executing the reliability calculation by using the subject similarity estimated value of the subject corresponding to the sentence unit to obtain the reliability estimated value corresponding to the subject; and finally, deciding the expanding mode of the sentence unit according to the reliability estimated value.

Description

Technical field [0001] The present invention relates to an automatic expansion method for teaching materials and a related learning materials expansion system, in particular to a method and system for automatic expansion of conversation teaching materials that integrate sentences, similarity of conversation flow structure and reliability measurement. Background technique [0002] In recent years, with the vigorous development of digital learning, more and more diverse teaching materials such as language learning materials can be provided for users to practice to assist users in learning. In language learning, the listening and speaking part has gradually moved from monotonous listening and speaking exercises to dialogue interactions that simulate real situations. However, in order to meet the real situation, a learning system (such as a situational simulation conversation learning system) must have a rich set of contextual conversation materials. [0003] A rich set of situational...
