In this paper the idea of the Loebner contest as a practical implementation of the Turing test is presented. The Brian Plüss’ measure of the degrees of non-cooperation in a dialogue is applied to the dialogues of the Loebner contest. The proposal of a typology of non-cooperative features in the contest’s dialogues is discussed and the reliability of annotation with the use of this typology of features is analyzed. The degrees of non-cooperation of judges and programs for the Loebner contest (editions 2009 – 2012) are presented and discussed. On the basis of the results the role of a judge and the strategies used by programs are discussed for the contest and the Turing test.
