Alchemy 7 and Markov thebeast. 8 4 Proposed Markov Logic Network As stated before, our aim is to jointly tackle Tasks A, B and C of the TempEval challenge. In this section we introduce the Markov Logic ... by predicting relations in a more global manner. However, while they focused only on the temporal relations between events mentioned in a document, we also jointly predict the temporal or- der...
