WebIn section 2, we describe the annotation tasks and datasets. In section 3, we discuss related work on inter-annotator agreement measures, and suggest that in pilot work such as this, agreement measures are best used to identify trends in the data rather than to adhere to an absolute agreement threshold. In section 4, we motivate The joint-probability of agreement is the simplest and the least robust measure. It is estimated as the percentage of the time the raters agree in a nominal or categorical rating system. It does not take into account the fact that agreement may happen solely based on chance. There is some question whether or not there is a need to 'correct' for chance agreement; some suggest that, in any c…
