abstract = {We study the task of span-level Emotion cause analysis (SECA), which is focused on extracting the specific emotion cause span(s) for a certain emotion expressed in the given context. Compared to popular clause-level emotion cause analysis (CECA), it is a finer-grained emotion cause analysis (ECA) task. The existing SECA method heavily dependents on the effectiveness of designed features, which is labor-intensive and not generalized well. In this paper, we formalize SECA as a sequence tagging task for which several variants of neural network-based sequence tagging models to extract specific emotion cause span(s) in the given context. These models combine different types of encoding and decoding approaches. Furthermore, to make our models more ``emotionally sensitive'', we utilize the multi-head attention mechanism to enhance the representation of context. Experimental evaluations conducted on two benchmark datasets show that our proposed models create new state-of-the-art results. Our work is the first using neural sequence tagging method for span-level ECA.},
