数据挖掘在多媒体资源库建设中的应用

The Applications of Data Mining in the Construction of a Multimedia Resource Library

现阶段,诸多高校资源库已初步建设,具备多种媒体且内容丰富,是实效性极大地数字化信息资源。多媒体主要是把众多静态影响以电信号方式进行捕捉及记录和处理,加上储存及传送和再现为动态影响,多媒体教学资源库可以说是各类教学资源的汇集,它不同于文本或图像等资源,教育教学使用中也非常便捷。其间信息有着模式多态性及不完整性和较强时间性,加上复杂性及冗余性。常用数据库和同级分析方式早已不能满足新形势下现实要求,多媒体教育资源库中仍存在诸多问题,比如资源库组织科学合理性及学习者学习中人性化及个性化等。文章分析了数据挖掘在多媒体资源库建设中的应用,并提出实用性构建策略,以期提升国内多媒体资源库建设水平。

In this stage, many colleges and universities have been the initial construction of the repository, with a variety of media and rich content, is the effectiveness of digital information resources dramatically. Multimedia mainly to the impact of many static electrical way to capture and recording and processing, plus storage and transmission and reproduction of the dynamic effects, multimedia teaching resource library can be said to bring together all kinds of teaching resources, it differs from the text or images, etc. resources, education is also very convenient to use. Meanwhile information has pattern polymorphism and incompleteness and strong timeliness, coupled with the complexity and redundancy. Common database and similar analytical methods already can not meet the practical requirements of the new situation, there are still many problems of multimedia educational resources, such as the repository organization learner scientiifc rationality and humane learning and personalization. This paper analyzes the data mining in the multimedia resource database application, and put forward the practicality build strategies to enhance the level of domestic multimedia resource library construction.
