COAL: Convolutional Online Adaptation Learning for Opinion Mining

Thanks to recent advances in machine learning, some say AI is the new engine and data is the new coal. Mining this ‘coal’ from the ever-growing Social Web, however, can be a formidable task. In this work, we address this problem in the context of sentiment analysis using convolutional online adaptation learning (COAL). In particular, we consider semi-supervised learning of convolutional features, which we use to train an online model. Such a model, which can be trained in one domain but also used to predict sentiment in other domains, outperforms the baseline in the range of 5-20%.
