What does confidence mean in Zooma?

Zooma assigns "Confidence scores" to mappings. Confidence scores are assigned as follows for a string of text

• High: Maps to single curated term
• Good: Maps to multiple curated terms OR maps to single non-curated term
• Medium: Maps to multiple non-curated terms
• Low: Default confidence level if none of the others apply.

Based on these confidence scores one can see that without a data source, Zooma will never give a high confidence score.
