Fuzzy String search algorithm using Soundex for Indian language
By mixing both written like(edit distance) and sounds like(soundex), we achieve an efficient aproximate string searching. This application is capable of cross language string search too. That means, you can search Hindi words in Malayalam text. If there is any Malayalam word, which is approximate transliteration of hindi word, or sounds alike the hindi words, it will be returned as an approximate match. The “written like” algorithm used here is a bigram average algorithm. The ratio of common bigrams in two strings and average number of bigrams will give a factor which is greater than zero and less than 1. Similarly the soundex algorithm also gives a weight. By selecting words which has comparison weight more than the threshold weight(which 0.6), we get the search results.
