There are bogus surveys galore—she takes commendable swipes at Alfred Kinsey and Shere Hite—but very little based on proper, probability-weighted samples, and even fewer international comparisons. - 摘要对简单贝叶斯分类中的条件概率加权因子进行了改进，引进了体现词语分类贡献大小的类别区别度，新的加权方法为频率与类别区别度的乘积，既强调了区别度高的词语，降低了常见词的影响，又体现了区别度高的词语频次的积极作用。
The weighted factor of conditional probability in Naïve-Bayes was ameliorated, the new factor is product of word's kinds-difference and frequency, which emphasizes words with high word's kinds-difference, incarnates frequency's positivity, on the contrary, reduces the affect of common words.
