A Fast and Accurate Dependency Parser using Neural Networks

For instance, Bohnet (2010) reports that his baseline parser spends 99% of its time do-ing feature extraction, despite that being done in standard efficient ways. In this work, we address all of these problems by using dense features in place of the sparse indi-cator features.

The success of delta idf weighting in previous work suggests that incorporating sentiment information into VSM values via supervised methods is help-ful for sentiment analysis. We adopt this insight, but we are able to incorporate it directly into our model’s objective function. (Section 4 ...

Learning Implicit Sentiment in Aspect-based Sentiment ...

Aspect-based sentiment analysis aims to iden-tify the sentiment polarity of a specific aspect in product reviews. We notice that about 30% of reviews do not contain obvious opinion words, but still convey clear human-aware sen-timent orientation, which is known as implicit sentiment. However, recent neural network-
