What’s a good Python profanity filter library? [closed]

Answer 1

You could probably combine http://spambayes.sourceforge.net/ and http://www.cs.cmu.edu/~biglou/resources/bad-words.txt.

Answer 2

WebPurify is a Profanity Filter Library for Python

Answer 3

I didn't found any Python profanity library, so I made one myself.

Parameters

---

filterlist

A list of regular expressions that match a forbidden word. Please do not use \b, it will be inserted depending on inside_words.

Example: ['bad', 'un\w+']

ignore_case

Default: True

Self-explanatory.

replacements

Default: "$@%-?!"

A string with characters from which the replacements strings will be randomly generated.

Examples: "%&$?!" or "-" etc.

complete

Default: True

Controls if the entire string will be replaced or if the first and last chars will be kept.

inside_words

Default: False

Controls if words are searched inside other words too. Disabling this

You can add or remove from the bad words list,arrBad, as you please.

Answer 5

It's possible for users to work around this, of course, but it should do a fairly thorough job of removing profanity:

import re
def remove_profanity(s):
    def repl(word):
        m = re.match(r"(\w+)(.*)", word)
        if not m:
            return word
        word = "Bork" if m.group(1)[0].isupper() else "bork"
        word += m.group(2)
        return word
    return " ".join([repl(w) for w in s.split(" ")])

print remove_profanity("You just come along with me and have a good time. The Galaxy's a fun place. You'll need to have this fish in your ear.")

Answer 6

Profanity? What the f***'s that? ;-)

It will still take a couple of years before a computer will really be able to recognize swearing and cursing and it is my sincere hope that people will have understood by then that profanity is human and not "dangerous."

Instead of a dumb filter, have a smart human moderator who can balance the tone of discussion as appropriate. A moderator who can detect abuse like:

"If you were my husband, I'd poison your tea." - "If you were my wife, I'd drink it."

(that was from Winston Churchill, btw.)
