Abstract
Abstract A method and apparatus for determining quality of a description are described. According to one embodiment, an exemplary method for determining quality of a description includes posing a classification task concerning at least one audiovisual object to a descriptive method that is used to create the description, generating a set of probabilities from a result of the classification task, and measuring an entropy of the result using the set of probabilities.

Claim 2
Dependent Claim
79 words
A computerized method for execution by a computer system for determining quality of a description, the method comprising: identifying a plurality of classes; posing a classification task concerning at least one audiovisual object to a descriptive method that is used to create the description; receiving numeric scores associated with the plurality of classes; normalizing the numeric scores; generating a set of probabilities from the normalized numeric scores; and calculating an entropy of the result using the set of probabilities.
Claim 3
Dependent Claim
25 words
The method of claim 1 further comprising comparing the measured entropy with an entropy resulting from a classification task performed by a plurality of persons.
Claim 4
Dependent Claim
21 words
