( Correction: the "Vector Space..." article is not
actually directly related to the OP's problem but does deal w/ the
"closeness of words" concept. In that regard, below is the corrected
version of my earlier reply.
UPDATE (Mar 3 2003): If anybody is still interested, i have rounded up some relevant things under
"string munging".

See
Vector Space Search Engine
article which does some similar things.
The String::Similarity and String::Approx modules may also be of
interest. Below are the descriptions (from FreeBSD ports)...
- String::Similarity
- The "String::Similarity" calculates the similarity index of its two
arguments. A value of '0' means that the strings are entirely different.
A value of '1' means that the strings are identical. Everything else lies
between 0 and 1 and describes the amount of similarity between the strings.
- String::Approx
- String::Approx lets you match and substitute strings approximately.
With this you can emulate errors: typing errors, spelling errors, closely
related vocabularies (colour color), genetic mutations (GAG ACT),
abbreviations (McScot, MacScot).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
