利用Python实现中文文本关键词抽取,分别采用TF-IDF、TextRank、Word2Vec词聚类三种方法。
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?
请问# 词向量写入csv文件,每个词400维是哪个代码设置的?
有针对这些算法进行提取效率的对比吗?效率如何
或者怎样衡量算法抽取的关键词就是文本的关键?
python3下,需要修改为:
stopkey = [w.strip() for w in codecs.open('data/stopWord.txt', 'r', encoding='UTF-8').readlines()]
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?
楼主您好!请问可以分享一下代码吗
IndexError: index 1 is out of bounds for axis 0 with size 1,想问下如何解决
下载完 直接运行python keyextract_word2vec_1.py 报“IOError: [Errno 2] No such file or directory: 'wiki.zh.text.vector'” 怎么解决?
用的是Python3,但在导出CSV时,关键词是'b'\xe7\x94\等,想问一下如何转换成汉字?
