Aspect-Based Sentiment Analysis at Semeval 2015
We address the OTE task as a sequence labeling problem. We use the ixa-pipe-ote system off-the-shelf to train our OTE models; ixa-pipe-ote uses the Apache OpenNLP project implementation of the Perceptron algorithm customized with its own local and word representation features.
