This document discusses aspect based sentiment analysis using recurrent neural networks. It describes annotating review data and developing a GUI for annotation. An API was created to extract aspect terms. A recurrent neural network model was implemented using Deeplearning4j with backpropagation through time to classify inputs. The system was trained on 1/3 of the data and achieved accuracy on the test data. Challenges included not reaching 100% accuracy and most terms being unrelated to aspects. Future work proposed using additional features and different neural network architectures.
