Question

Compare the similarity of 2 given addresses

Hi,

The way below is good to compare the similarity of 2 given addresses? We expect to achieve that while 80% of the words (in the different position) are appearing well within both strings. Possible to achieve that? Or any other better to do that?

Hi @Jonathan

Please try the below method will achieve the your result.

public static double WordMatchPercentage(string a, string b)
{
 var words1 = a.ToLower().Split(' ', ',', '.')
 .Where(x => !string.IsNullOrWhiteSpace(x))
 .ToHashSet();
 
 var words2 = b.ToLower().Split(' ', ',', '.')
 .Where(x => !string.IsNullOrWhiteSpace(x))
 .ToHashSet();
 
 int matched = words1.Intersect(words2).Count();
 
 int maxWords = Math.Max(words1.Count, words2.Count);
 
 return (double)matched / maxWords * 100;
}

Thanks.
