word index

This thesis introduces the system framework and main modules " technique . the system improves the lucene ' s score mode for web - based full - text ir . this thesis compares the search precision between word - segmented index based on ictclas and single chinese character index
本文设计并实现了一个web全文信息检索系统,介绍了系统的设计框架和主要组成模块的实现技术,并改进了lucene的评分方法用于web全文信息检索,对基于ictclas的词索引和字索引进行了查询对比。
Because the watermark embedding and the noisy channel were directly related to the codeword index order in the model , at the same time deciding the codeword index was a np - hard problem typically , so the ant colony algorithm was introduced to optimize it in order to make the bit error rate lower and the embedded watermark more invisible
在该模型中，由于水印嵌入和通道噪声直接与码字索引相关，所以该模型误差由索引值决定，又由于码字索引的确定是np难度问题，故引入蚁群算法对其优化是方便的，优化目标是降低误码率和使不可见性达到最佳。
