The paper describes the approaches and the results of our participation in the protein-protein interaction (PPI) extraction task (sub-tasks 1 to 3) of the BioCreative II challenge.1 The core of our approach is to analyse the logical forms of those sentences which contain the mentioning of relevant protein names, and to rank the sentences from which the relations where extracted using the class descriptors computed in the sub-task 1 and interaction sentences from the Christine Brun corpus.
