Representation: **simil


Humdrum Representation for Similarity Values

REPRESENTATION

**simil – similarity representation

DESCRIPTION

The **simil representation encodes numerical values that indicate the **Damerau-Levenshtein edit distance** between two other Humdrum representations. Data tokens for **simil consist only of decimal numbers. The value 1.0 indicates identical material beginning at the current data record. Lower numerical values indicate increasingly less similarity at the current data record.

FILE TYPE

It is recommended that files containing predominantly **simil data should be given names with the distinguishing `.sim’ extension.
