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. For example, the confidence level for a serial number pattern may only be 0.5 (medium); however, if you add keywords, the confidence level may increase by 35%.

The Keywords page allows you to mange the keywords assigned to the entity type. You access this page using the Manage keywords option for an entity type.
