The algorithm may now terminate or may be called recursively to describe o4 as well, resulting in a description that could be subsequently realised as in, e.g., 'the cone near a/the large box'.
attribute selection is usually driven by discriminatory power (Olson, 1970) (e.g., in the above example, only properties that rule out at least one distractor object are selected), and it is heavily influenced by the order P in which attributes are considered for inclusion in L. output descriptions may vary considerable both in length and in the kinds of information that they convey (Paraboni, 2003).
