In UiPath Document Manager, for string fields, the available options for scoring include:

Exact match: This checks whether the extracted string exactly matches the expected value.

Levenshtein: This method computes the "distance" between two strings, which is the number of single-character edits (insertions, deletions, or substitutions) required to change one string into the other. It is used to assess the similarity between the extracted string and the expected value.

These scoring methods help evaluate the accuracy of string extraction in the document understanding process.
