Improve Lexicon-based Word Embeddings By Word Sense Disambiguation

no code implementations24 Jul 2017 Yuanzhi Ke, Masafumi Hagiwara

To evaluate the proposed method, we compare the performance of the word embeddings trained by our proposed model, the control groups without the filter or the lexicon, and the prior works in the word similarity tasks and text classification task.

Alleviating Overfitting for Polysemous Words for Word Representation Estimation Using Lexicons

no code implementations2 Dec 2016 Yuanzhi Ke, Masafumi Hagiwara

We compare the proposed neural network with the continuous bag-of-words model, the other works improving it, and the previous works estimating distributed word representations using both a lexicon and a corpus.
