 |
|
@Just to let people working on drones know:
I found this algorithm earlier from wikipedia. If this can be implmented into TCL, it can be used as a scorer for drone nicks.
| Quote: |
The Soundex code for a name consists of a letter followed by three numbers: the letter is the first letter of the name, and the numbers encode the remaining consonants.
Similar sounding consonants share the same number so, for example, the labial B, F, P and V are all encoded as 1. Vowels can affect the coding, but are never coded directly unless they appear at the start of the name.
The exact algorithm is as follows:
Retain the first letter of the string
Remove all occurrences of the following letters, unless it is the first letter: a, e, h, i, o, u, w, y
Assign numbers to the remaining letters (after the first) as follows:
b, f, p, v = 1
c, g, j, k, q, s, x, z = 2
d, t = 3
l = 4
m, n = 5
r = 6
If two or more letters with the same number were adjacent in the original name (before step 1), or adjacent except for any intervening h and w (American census only), then omit all but the first.
Return the first four characters, right-padding with zeroes if there are fewer than four.
Using this algorithm, both "Robert" and "Rupert" return the same string "R163" while "Rubin" yields "R150".

Maybe if someone makes a system, it could be used to score against drones. Just need to find a way of matching the outcome to being a trojan/drone nickname...?

I searched the forum for soundex and found one match. A post by user in a drone matching topic regarding regexp, where he advised soundex to be used with a dictionary for matching drones. And we all know that user is never wrong.

Here's a great idea which i'm about to patent:
Look the nick up in a dictionary. If not found; kick the person telling them to correct the spelling error.
Seriously though...
Have you tried using soundex? I think it would work much better than just relying on the random string not containing certain chars. I suggest using a soundex "dictionary", a list or array of soundexes based on the words from a real dictionary + common names. This dictionary could then be searched to see if the soundex of a nick == some existing word's soundex, which should weed out most random strings.
Then you could have a mechanism for re-entering the room that you tell about in the kick reason, so those not meant to be kicked can rejoin. (a /msg command or what ever)
This is of course just theory and fairly cpu/memory intensive stuff, but IMO worth a try

That's the beauty of my method (I think/hope), because even if they're not real words most nicks SOUND like real words. Except strange nicks like where a number becomes a couple of chars in a word etc...but these could be translated to chars with a 'string map' before the soundex is made (in most cases) and the rest would be allowed to re-enter through the /msg command

Now that's a different story, it's not just checking soundex over nicknames - there's a dictionary involved and I agree that it would work but far too much effort would be done over a really not that big of a problem.

And where do we find a soundex dictionary, or how make one. It will to too time consuming to a human to read and enter each word from a dictionary into soundex and store it in a file/db.

Ask user, he's the one who suggested it, so he would know better. I don't think you need to make a dictionary, thats obviously ridiculous.. maybe use one from a tcl library or maybe from the web.
