In this model, we first use the probabilistic latent semantic analysis to extract the seed emotion words from the Wikipedia and the training corpus. Then features are extracted from these seed emotion words, which are the input of the maximum entropy model for training the maximum entropy model....

This paper mainly present an interpretable neural net framework for financial sentiment analysis. First, it designed a hierarchical model to learn the representation of a document from multiple granularities. Specifically it built representations of sentences from individual words and then aggregate those...
