Relations To Other Models
The well-founded semantics can be viewed as a three-valued version of the stable model semantics. Instead of only assigning propositions true or false, it also allows for a value representing ignorance.
For example, if we know that
Specimen A is a moth if specimen A does not fly during daylight.
but we do not know whether or not specimen A flies during the day, the well-founded semantics would assign the proposition ``specimen A is a moth`` the value bottom which is neither true nor false.

Famous quotes containing the words relations and/or models:
“I know all those people. I have friendly, social, and criminal relations with the whole lot of them.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“French rhetorical models are too narrow for the English tradition. Most pernicious of French imports is the notion that there is no person behind a text. Is there anything more affected, aggressive, and relentlessly concrete than a Parisan intellectual behind his/her turgid text? The Parisian is a provincial when he pretends to speak for the universe.”
—Camille Paglia (b. 1947)
