摘要: 为了揭示SWF文件格式的隐含属性,基于对象交换模型(OEM)的构建方式,提出了一种增强半结构化模型E-OEM,可对SWF文件格式进行描述和存储.采用OEM进行SWF文件格式的描述;对OEM描述模型进行改进,采用头尾分类、文件体聚类的思想将相同类别标签作为一类;通过引入Huffman编码,实现E-OEM具有描述和存储的功能.随机选择百例不同源文件进行E-OEM建模,仿真实验结果表明,所提模型不仅可以将隐含属性显性表示,同时提高了具有高标签重复率的文件存储效率,证实了模型的有效性.

Abstract: It's difficult to reveal hidden relationships of the shockwave flash (SWF). The article proposed an enhancement object exchange model (E-OEM) based on object exchange model (OEM). This model can describe and store SWF file format. First, SWF file format is described though OEM. Then, OEM descriptive model is improved with classifying the head and the end, clustering the body. E-OEM could realize the function of description and storage through Huffman coding. Also, 100 different source files are used to build semi-structure model. It is shown that E-OEM has a good impact on the relationship dominance, and can implement effective retrieval of high tag repetitive rate, and the storage rate is improved. It is shown that the model is valid.

Key words: shockwave flash file format, enhancement object exchange model, Huffman coding, semi-structured model
