How LSTM Encodes Syntax: Exploring Context Vectors and Semi-Quantization on Natural Text

no code implementations COLING 2020 Chihiro Shibata, Kei Uchiumi, Daichi Mochihashi

For some dimensions in the context vector, we show that their activations are highly correlated with the depth of phrase structures, such as VP and NP.

MIPA: Mutual Information Based Paraphrase Acquisition via Bilingual Pivoting

1 code implementation IJCNLP 2017 Tomoyuki Kajiwara, Mamoru Komachi, Daichi Mochihashi

We present a pointwise mutual information (PMI)-based approach to formalize paraphrasability and propose a variant of PMI, called MIPA, for the paraphrase acquisition.
