Description: 索引词的选择
1、 切词及词频统计：利用已选择的分词软件对文档进行切词处理，并进行词频统计，形成DocIndex文件，结构为：文档号、频率、词。注意保留中间结果，建立合理的数据结构来存储。
2、 分配词权重： 采用词频标准化（tfi = tfi/Max(tf)）和tf*idf两种方式分配词的权重。由DocIndex文件生成DocIndex(tf) 和DocIndex(tf*idf)文件。注意阈值的确定，词的取舍。
3、 形成倒置文档：将DocIndex(tf) 和DocIndex(tf*idf)文件转换为DocInvert(tf) 和DocInvert (tf*idf)文件。-Index word choice, the cut word and word frequency statistics: the use of the selected word segmentation software documentation the cut word processing, and word frequency statistics to the formation DocIndex file structure: document number, frequency, word. Note retain intermediate results, establish a reasonable data structure to store. 2, is assigned the term weight: the using word frequency Standardization (TFI = the TFI/Max (TF)) and tf* idf two ways to allocate the right of the word weight. Generated by DocIndex file DocIndex (tf) and DocIndex (tf* idf) files. Attention to the determination of the threshold, the word choice. 3, the formation of the inverted document: the DocIndex (tf) and DocIndex (tf* idf) files into DocInvert (tf) and DocInvert (tf* idf) files.
