keyword_extraction's Issues

关于乱码问题

大佬您吼~~我按照您word2vec+聚类的代码跑了一遍,但是输出的csv文件的关键词一直存在着编码的问题,key那一列对应的是b"b'\xe8\x8d\xaf\xe7\x89\xa9' b'\xe5\x..这种格式,不知道您有没有好的建议可以修改?

词的维度

请问# 词向量写入csv文件,每个词400维是哪个代码设置的?

关于tf-idf模型候选数据集过大,是否越大越好?

我数据集情况,三类标签,每个类别1W条以上数据。我需要每个标签提取20-50个关键词。

由于数据集多大,jieba分词速度慢,占内存大外,用于训练tf-idf时候出现很多负例(无效关键词),影响模型效果。现在自己做法是限制词频。但想问数据集是否过大需要调整么?该怎么做?
