Hi all,
Does anyone now if there is a way to do a fuzzy string compare in c#?
For example, comparing 'cat' to 'cats' would return something like a
90% match ratio. I was told that this type of fuctionality exists in
Perl but I can't find anything about it in c#.
Thanks

Don't waste your time investigating regular expressions as suggested; a
regexp either matches or does not match, there is no fuzziness about it.
Regexps *may* help you in implementing a fuzzy matching algorithm in some
small way.
I'd suggest that you may want to investigate ways to implement the
Levenshtein distance if you are comparing multiple terms. The following
link has a nice explanation and source code in VB, Java and C http://www.merriampark.com/ld.htm
and here's the c# version for the truly lazy :) http://www.merriampark.com/ldcsharp.htm

I was wondering if anyone had tried implementing fuzzy logic set
concepts in C++, because in FL, the concept of "type" or "class"
is fuzzy; things belong (or are of) a given type only by degree.
e.g., in a hypothetical fuzzy C++ language one could say:
class pickle : public vegetable 0.2
{
// pickle is not so much a vegetable as, say, onion is.
};

Hi All
We are using soundex (and later tried Nysiis) for fuzzy name search
software. But we faced a lot of problems the search accuracy was not very
good also we saw a lot of misses of relevant names.
There are many problems other than precision and accuracy, with soundex and
NYSIIS.

I have roughly 20 MS excel spreadsheets, each row contains a record.
These records were hand entered by people in call centers.
The problem is, there can and are duplicate phone numbers, and emails

(roughly 300,000+ records and use fuzzy logic to break it down, so that

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
