背景: 刚接触这个领域,请教老师问题

过程:

对2G多的那个train.json中的fact提取,分词,再用word2vec训练出词向量,结果:1280257个词,4.66G。

我看您训练后的只有1G多,觉得可能和没有去除停用词有关,可能和分词后没有去重有关,去掉停用词后,1440045个词,5.24G,数量不减反增,没想明白为什么。

问:

1)一般情况下对语料分词后要不要去除停用词,如果去掉的话,在用词向量表示文档的时候,会不会丢失语义,比如:导致,由于,传说等词,且数字需不需要去掉,因为日期,电话号码等在某些领域很多,是有意义的。

2)在分词的时候,每读取一行语料,分词,写入词文件,这样势必会产生很多相同的词语,这个时候要不要去重,不知道您是怎么做的。

感谢。

请问那个里面的question.train 文件有吗?我看他们都没有找到
