Triple: dbr:Michael_Jackson @dbo:activeYearsStartYear 1964^^http://www.w3.org/2001/XMLSchema#gYear

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".
