摘要
基于可变精度粗糙集提出了一种统一的文本与图像分类算法.用该方法进行教育资源的分类既可处理不确定性信息,又简化了分类规则,从而有利于提高分类能力和检索的查准率.
The volume of data in education resources library is increasingly large. How to retrieve useful information from such data collections is an important issue. Effective information categorization is very important to information retrieval. A uniform text and image categorization methodology based on Variable Precision Rough set is proposed, which can apply to uncertain information model and improve the categorization capability.
