Dataset for Benchmarking Aspect Level Sentiment Classification on Reviews Requiring Coreference Resolution

We present the ALSC-CR dataset for Aspect Level Sentiment Classification (ALSC). This dataset can be used to benchmark ALSC model performance on reviews that require coreference resolution (CR) ability to perform well. For example, CR is needed to predict the sentiment for "food" in the sentence - "I had food, it was bad." Here, "food" has a negative sentiment only because it is referring to the same entity as "it" which in turn is associated with a negative sentiment.
