Help Needed in Spellchecking of a keyword

[Srikanth]

Hi,

We need to check the spelling of a word which is actually a Domain
name. For example we have to check the word " onlinetradeing ".
When checked with the spell checkers we are getting the words which are
unrelated such as on, obliterating, incinerating, intruding etc. But
exactly what we want was " online trading ". So we would like to
have the word to be split into phrases and check the spelling too. The
normal spell checkers are just checking the words in the dictionary but
not splitting the word into phrases.

Can any one help me...?

Regards
L.Srikanth.

If the spell checker doesn't do that, there is little Perl can do
about it.

You could split each "word" in parts in all possible ways and let
your spell checker have a go at them:

$_ = 'onlinetrading';

for my $break ( 1 .. length() - 1 ) {
pos = $break;
my ( $first, $last) = split /\G/;
print "$_ = $first + $last\n" if check( $first) && check( $last);
}

but that would presumably take quite some time. It still wouldn't
recognize "onlinetradingcenter", which must be broken into three parts.

I doubt there is a practical way to do that unless you find or write
a spelling checker that supports it directly.

Please don't multi-post. (
Use an English wordlist, chop off the longest matching word from the
end, and repeat that.
If that doesn't end with an empty string, do the same from the start,
repeat that, and report both the failing and the remaining string.

With some backtracing, this can of course be easily improved on, if
that's worth it.

A speedy alternative is to use a hyphenation algorithm first, and step
(back) by syllable (in stead of letter).
