我是一个绝对的初学者.从未使用Java在weka中创建分类器或任何东西我以前使用过该接口.基本上我有点失落我已经看过weka的过滤器类并且玩了一下它.我的文件是文本文件,我需要将它们分为两类.

我不确定如何定义类别或如何将文档加载到要分类的IDE中

:-(

任何帮助/教程或指针将不胜感激.

创建了一个python模块,它读取文件,删除停用词并输出一个python字典,其中包含单词及其频率(文档中出现的次数).

def run():
filelist = os.listdir(path)
regex = re.compile(r'.*<div class="body">(.*?)</div>.*', re.DOTALL | re.IGNORECASE)
reg1 = re.compile(r'<\/?[ap][^>]*>', re.DOTALL | re.IGNORECASE)
quotereg = re.compile(r'&quot;', re.DOTALL | re.IGNORECASE)
puncreg = re.compile(r'[^\w]', re.DOTALL | re.IGNORECASE)
f = open(stopwordfile, 'r')
stopwords = f.read().lower().split()
totalfreq = {}

filewords = {}
htmlfiles = []
for file in filelist:
    if file[-5:] == '.html':
        htmlfiles.append(file)

for file in htmlfiles:
    f = open(path + file, 'r')
    words = f.read().lower()
    words = regex.findall(words)[0]
    words = quotereg.sub(' ', words)
    words = reg1.sub(' …

我在Python中创建了一个Google App Engine项目,它在我的localhost上运行但是当我将它上传到geo-event-maps.appspot.com时,标记没有显示.我有一个cron,它可以调用/放置.我没有日志错误我的数据存储空了!正在上传txt文件:

    file_path = os.path.dirname(__file__)
    path = os.path.join(file_path, 'storing', 'txtFiles')

有没有办法检查文件是否已上传？!

我绝对亏损.以前有没有人遇到过这些问题？

下面是我的main.py:

我有一个Python脚本,它接收'.html'文件删除停用词并返回python词典中的所有其他单词.但是如果在多个文件中出现相同的单词,我希望它只返回一次.即包含不间断的单词,每次只包含一次.
