求翻译：D , ij tf is the frequency of j t appears in document I D , N is the number of documents in the collection, and n is number of documents where term j t appears at least once. In a word, the higher weight of a term the higher discriminating power the term has. After calculating the weight for each distinct term, we sel是什么意思？ 待解决

D，IJ TF的JT文档ID出现的频率，n是集合中的文件数量，n是长期JT出现至少一次的文件数量。一个字，一个长期的更高的权重较高的鉴别力一词。每个不同任期的重量计算后，我们选择前n个方面，形成了VSM。 n是常常平衡计算成本和鉴别力的基础上，通过试验和错误决定。由一个SOM算法的初始化和训练阶段。在初始阶段，一些单位和输出层的拓扑结构，首先确定，然后每个输出层的单元IM参考矢量启动，其中每个参考向量
