Abstract

Despite the linear use of PowerPoint presentation slides in classroom and lecture halls, the brain works primarily with key concepts that it links and integrates. This is a big contrast from the typical student behaviour of reading or memorizing the slides.This paper presents a new system that automatically generate a mind map based on a set of keywords and keyphrases extracted from PowerPoint presentation slides. The system takes a text mining approach and relies on a keyphrase extraction algorithm to extract the keywords and keyphrases. Survey results reflect a rising need of such application as part of educational technologies and the potential benefits are observed and discussed.

otommind:自动概念映射的文本挖掘方法

尽管在教室和演讲厅里使用的是线性的ppt幻灯片，但大脑主要是用它连接和整合的关键概念来工作的。这与典型的学生阅读或记忆幻灯片的行为形成了很大的对比。本文提出了一种基于从PowerPoint幻灯片中提取的一组关键字和关键短语自动生成思维导图的新系统。该系统采用文本挖掘方法，并依靠关键字提取算法提取关键字和关键短语。调查结果反映出，作为教育技术的一部分，对此类应用的需求日益增长，并观察和讨论了潜在的好处。
