About Entity Extraction and CTX_ENTITY

Entity extraction is the identification and extraction of named entities within text. Entities are mainly nouns and noun phrases, such as names, places, times, coded strings (such as phone numbers and zip codes), percentages, and monetary amounts. The CTX_ENTITY package implements entity extraction by means of a built-in dictionary and a set of rules for English text. You can extend the capabilities for English and other languages with user-provided add-on dictionaries and rule sets.
