Generated sentence:
Michael Jackson's active years start year is 01 January 1964

"Active years start year" is a good identifier for ontology, but not particularly good for natural language.
Human would most likely write here: Michael Jackson has started his career on 01 January 1964. Hence the mapping "active years start year" --> "has started his/her career".
