Apsect Based Sentiment Analysis (ABSA) python implementations

• SemEval 2014 solutions:
  • NRC Canada: http://www.aclweb.org/anthology/S14-2076
  • JUSCE
• SemEval 2015 solutions: TBD
• Deep Learning solutions for ABSA:
  • CNN based impl by Wang & Liu (Stanford): https://cs224d.stanford.edu/reports/WangBo.pdf
  • LSTM based impl by Tang et. al.: https://arxiv.org/pdf/1605.08900.pdf

For stanford corenlp python wrapper, https://github.com/dasmith/stanford-corenlp-python is used

• Need to run 'python corenlp.py' first. This starts a RPC service that is invoked by other python wrapped APIs.
• Since this RPC invoations, CANNOT RUN PARALLEL requests!
• Need to make sure 'jsonrpc.py' is in the same folder as 'corenlp.py'
• import jsonrpc, that's it!
