Overview

You can add keywords to regular expression entity types. Keywords improve the match accuracy by providing a list of terms that may appear in close proximity to the entity you want to identify. A term is considered as close proximity if it within 5 words behind the match. These keywords boost the confidence level of a given match. In the example below, the confidence level for the serial number pattern is only 0.5 (medium); however, if you add keywords, the confidence level increases by 35% (as noted by the green percentage displayed on the right of this section).
