About Our Fuzzy Text Matching Algorithms

What is Fuzzy Text Matching?

Fuzzy text matching is a technique that allows for a degree of error in text comparisons. Unlike exact matching, fuzzy matching can identify texts that are similar but not identical, which is useful for handling spelling errors, OCR results, natural language processing, and more.

Our tool provides multiple advanced fuzzy matching algorithms to help you find the best matches across various scenarios.

Our Algorithms

Edit Distance (Levenshtein)

The Edit Distance algorithm calculates the minimum number of operations (insertions, deletions, substitutions) required to transform one string into another. The smaller the distance, the more similar the strings.

N-gram Similarity

The N-gram algorithm breaks text into continuous segments of n characters or words, then compares the overlap between these segments. This method is particularly effective for capturing local similarities in text.

Cosine Similarity

Cosine Similarity represents texts as points in vector space, then calculates the cosine of the angle between these vectors. This method is particularly effective when dealing with texts of different lengths.

Jaccard Similarity

Jaccard Similarity calculates the size of the intersection divided by the size of the union of two sets. In text matching, we treat texts as sets of characters or words and calculate their overlap.

Mixed Algorithm

Our Mixed Algorithm combines the strengths of all the above methods, providing a more comprehensive and accurate similarity assessment through weighted averaging. This approach performs excellently across various text matching scenarios.
