Opinion target extractionis a fundamental task in opinion mining. In recent years,neural network based supervised learning methods haveachieved competitive performance on this task. However, aswith any supervised learning method, neural network basedmethods for this task cannot work well when the training datacomes from a different domain than the test data. On the otherhand, some rule-based unsupervisedmethods have shown to berobust when applied to different domains. In this work, weuse rule-based unsupervised methods to create auxiliary labelsand use neural network models to learn a hiddenrepresentation that works well for different domains. When this hiddenrepresentation is used for opinion target extraction, we findthat it can outperform a number of strong baselines with alarge margin.
