a novel neural network ensemble architecture for time series forecasting

Addition- ally, semantic roles can also be labeled with one of 13 ARGM adjunct labels, such as ARGM-LOC or ARGM-TMP for additional locational ... predicates identified by ASSERT we instead obtain 84.32% accuracy for our network, and 87.02% for ASSERT. 6 Discussion We have introduced a neural network architecture that can provide computationally ... locational or temporal information relative to some verb. Shallow semantic parsing has immediate applica- tions in tasks such as meta-data extraction (e.g. from web documents) and question and answer...
