String Similarity Score

String Similarity Score evaluates how closely two text strings match and returns a numeric score from 0.0 (no similarity) to 1.0 (identical).

It is designed for cases where exact matching is too strict, such as names, titles, or user-entered text.

You provide two strings as input and use the returned score to decide whether they should be treated as the same or related value.

This can support duplicate detection by flagging records that look very similar even when not identical.

It can also help handle spelling variations or partial matches, for example comparing “Jonas” with “Jonas Müller.” The score is easy to interpret and can be used to build simple rules (e.g., accept matches above a chosen threshold).

It is useful in data cleaning workflows to identify likely duplicates before merging or reviewing records.

It can also improve search or matching experiences by tolerating minor differences in how users enter text.

Overall, it provides a consistent, quantitative way to measure text similarity for fuzzy matching tasks.
