Up to january 2005 , the unique and growing corpus contains over 150 million chinese characters and over 720 , 000 word types , and is still expanding . the centre has launched a bi - weekly Livac所建立的是一个包括字词条文句全文等不同层次的语料库,可对个别字或词的使用作查询频率统计比较。
Then the threads in segmenting document into different topic is introduced , which includes statistical methods and semantic network . then , the rocchio model characteristics in text filter are analyzed 然后,介绍了根据不同线索将文本中不同子主题切分的技术,这些线索包括词义网络和各个段落关键词出现的频率统计,并指出它们各自的优缺点。
" level 01 " to " level 20 " are defined by frequence . if you are a high school student , you can select " level 01 " commonly ; if you are a college student , you can select " level 01 " to " level 03 " commonly ; under high school can select basic words 词汇级别中的level 01 level 20是根据单词出现的频率统计的,如果你是高中水平,选择level 01一般没有问题,如果是大学水平,一般可以选择level 01 level 03 ,高中以下水平可以选择基本词汇。
So a new method is proposed that combines the traditional transfer function and coherence function analysis with the statistics of frequencies to obtain the dominant frequencies , which can reflect how the noise sources influence the bus interior noise level in frequency domain , and which will provide reliable references to make up plans in reducing the bus interior noise 对此提出了在传统的传递函数和相干函数分析的基础上结合频率统计,选出优势频率的方法来考察噪声源对车内噪声的影响,为制定客车车内噪声治理方案提供了可靠的依据。
These control ways include fuzzy evaluation , the method of fha , the theory of grey forecast and control diagram , etc . the application of these control methods obviously reduced the ratio of waste web , enhanced the process quality and , ameliorated the whole quality management system and increased the customers " satisfaction 本论文在对芜湖华辰公司聚酯网生产过程质量控制现状进行分析的基础上,针对影响过程质量的主要因素提出了一整套的控制方法,这些方法包括模糊评价、 fha (频率统计分析)法、灰色预测理论、控制图等。
