First, we evaluate ConvLexLSTM performance in an ablation experiment to determine the role played by each component for emotion detection.
we compare ConvLexLSTM with ConvLSTM (a model that has the same architecture as ConvLexLSTM, but does not use any external lexicon), CNN, LSTM, and support vec-  tor machine (SVM) with the (concatenated) features from the seven lexicons (described above).
