That is, although the co-mentioning of two or more candidates in a tweet will likely confuse the sentiment classifier, it does not appear to happen in a systematic way for any particular candidate, meaning that such errors are likely to be evenly distributed. Secondly, the aggregated sentiment for every day has to be determined. Twitter Sentiment Analysis using combined LSTM-CNN Models Pedro M. Sosa June 7, 2017 Abstract In this paper we propose 2 neural network models: CNN-LSTM and LSTM-CNN, which aim to combine CNN and LSTM networks to do sen- timent analysis on Twitter data. Sentiment analysis is the automated process of identifying and extracting the subjective information that underlies a text. As such, we might get more insight in the potential correlation between these variables. Both the number of tweets over time and the weighted aggregated sentiment show significant ups and downs.
