funSentiment at SemEval-2017 Task 4: Topic-Based Message Sentiment Classification by Exploiting Word Embeddings, Text Features and Target Contexts
2017
Proceedings of the 11th International Workshop on Semantic Evaluation (SemEval-2017)
We use two types of word embeddings in our classifiers: the general word embeddings learned from 200 million tweets, and sentiment-specific word embeddings learned from 10 million tweets using distance ...
We also incorporate a text feature model in our algorithm. This model produces features based on text negation, tf.idf weighting scheme, and a Rocchio text classification method. ...
Our approach uses word embeddings (WE) learned from general tweets, sentiment specific word embeddings (SSWE) learned from distance supervised tweets, and a weighted text feature model (WTM). ...

Learning Sentiment-Specific Word Embedding for Twitter Sentiment Classification
2014
Proceedings of the 52nd Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers)
To obtain large scale training corpora, we learn the sentiment-specific word embedding from massive distant-supervised tweets collected by positive and negative emoticons. ...
Specifically, we develop three neural networks to effectively incorporate the supervision from sentiment polarity of text (e.g. sentences or tweets) in their loss functions. ...

THU_NGN at SemEval-2018 Task 1: Fine-grained Tweet Sentiment Intensity Analysis with Attention CNN-LSTM
2018
Proceedings of The 12th International Workshop on Semantic Evaluation
Traditional sentiment analysis approaches mainly focus on classifying the sentiment polarities or emotion categories of texts. However, they can't exploit the sentiment intensity information. ...
A CNN layer with different kernel sizes is used to extract local features. The dense layers take the pooled CNN feature maps and predict the intensity scores. ...

Proceedings of the 9th Workshop on Computational Approaches to Subjectivity, Sentiment and Social Media Analysis
Word embeddings such as Word2Vec are efficient at incorporating semantic and syntactic properties of words, yielding good results for document classification. ...
We train Sentiment Specific Word Embeddings (SSWE) on top of an unsupervised Word2Vec model, using either Recurrent Neural Networks (RNN) or Convolutional Neural Networks (CNN) on data auto-labeled as ...
Through backpropagation, the weights of the Embedding Layer will be adjusted and incorporate sentiment. ...
