This calculates the similarity between two strings as described
|
|
in Oliver [1993]. Note that this implementation does not use a
|
|
stack as in Oliver's pseudo code, but recursive calls which may
|
|
or may not speed up the whole process. Note also that the
|
|
complexity of this algorithm is O(N**3) where N is the length of
|
|
the longest string.

<para>
|
|
By passing a reference as third argument,
|
|
<function>similar_text</function> will calculate the similarity
|
|
in percent for you. It returns the number of matching chars in
|
|
both strings.
