Entity extraction is the capability to identify, and extract, named entities within a text. Entities are mainly nouns and noun phrases. They include names, places, times, coded strings (such as phone numbers and zip codes), percentages, monetary amounts and many others. The CTX_ENTITY package implements entity extraction by means of a built-in dictionary and set of rules for English text. The capabilities can be extended for English, or for other languages, by means of user-provided add-on dictionaries and rule sets.
See the topic "CTX_ENTITY Package" in Oracle Text Reference and the topic "Entity Extraction User Dictionary Loader (ctxload)" in Oracle Text Reference for additional information about using entity extraction
