Many interesting phenomena in conversa- tion can only be annotated as a subjec- tive task, requiring interpretative judge- ments from annotators. This leads to data which is annotated with lower lev- els of agreement not only due to errors in the annotation, but also due to the differ- ences in how annotators interpret conver- sations. This paper constitutes an attempt to find out how subjective annotations with a low level of agreement can profitably be used for machine learning purposes. We analyse the (dis)agreements between annotators for two different cases in a multimodal annotated corpus and explic- itly relate the results to the way machine- learning algorithms perform on the anno- tated data. Finally we present two new concepts, namely ‘subjective entity’ clas- sifiers resp. ...
