weka csv to arff特殊字符caue错误 [英] Weka csv to arff special characters caue error

问题描述

我刚开始接触Weka，并且无法将包含Tweets的CSV文件转换为Arff文件。

I'm new to Weka and having problems converting a CSV file containing Tweets into an Arff file.

Tweet,Class
Conference Update: 50% Off Registration to End .. http://t.co/nZtkSzZnJ6,Yes

< hr>

当我尝试使用Explorer转换为.arff时，我收到以下错误
...无法识别为CSV数据文件原因：错误的值数。读取1预期2，读取令牌[EOF]，第2行

---

When I try to convert to .arff using Explorer, I receive the following error "...not recognized as an CSV data files Reason: wrong number of values. Read 1 expected 2, read token[EOF], line 2"

删除％字符允许文件无错误地转换为arff。我可以删除％和其他字符，但我真的不想改变我的Tweet数据。用单引号或双引号括起来也没有帮助。任何想法我做错了什么？

Removing the "%" character allows the file to convert to arff without error. I could remove "%" and other characters but I really don't want to alter my Tweet data. Enclosing in single or double quotes does not help either. Any idea what I am doing wrong?

欣赏任何帮助

推荐答案

Weka可以用％作为注释的开始，并忽略％和该行的其余部分。

Weka may interprete "%" as a begining of comment, and may ignore "%" and rest of that line.

请将整个字段

例如：
一个csv文件，其中内容

For Example: A csv file which contents following two lines, may be able to convert to Arff file by Weka.

PS $ b $对我有用[0]丢个板砖[0]引用|举报|编辑删除管理回复次数：0 |举报|字号大中小订阅用微信扫一扫将文章分享到朋友圈。作为转义字符，因此\使注释分隔符％变为正常字符％。

P.S. I'm sorry that my previous answer is incorrect. PRIVIOUS　ANSWER (Incorrect answer) was: Try to replace "%" character to "\%". "\" works as escape character, so "\" makes the comment-delimiter character "%" to a normal character "%".
