Which type of determination signifies that a record is definitely not a match?

The determination that signifies a record is definitely not a match is "No match." This designation is used when the evaluation process has conclusively found that the two records being compared do not share sufficient commonalities to be considered the same entity. It is a definitive outcome indicating that the records diverge in key identification fields and fail to meet the criteria for being seen as the same.

In contrast, the other options reflect varying degrees of uncertainty or potential alignment. A high threshold match implies a strong likelihood of similarity but is not an absolute conclusion, while a low threshold match suggests a possible connection, lacking sufficient evidence to confirm a definitive match. A potential match indicates that there are some overlapping attributes meriting further review but does not assert a clear and conclusive determination. This illustrates the critical nature of the "no match" category, as it provides a conclusive endpoint in the assessment process.
