Hi Gandhi, As for the error in EventTimeRelationAnnotator, the reason is that the time-class attribute value for an temporal expression mention is missing. When we develop this annotator, we used time-class in the gold annotation as a feature to help the classifier. If this feature is missing, the system can still predict event-time relation, but the performance will drop a little. Our test on SemEval 2015 data shows if the temporal attributes are missing, the system performance will drop 0.012 in F-score (Table 4 of https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5009920/).
If you really want this time-class feature, please add ³BackwardTimeAnnotator² into your processing pipeline, which will annotate temporal expressions and predict their time classes. Please keep in mind that this annotator is not 100% accurate either.
