We based our work on the SOPA 2015 system. The SOPA-2015 system used 16 similarity features (including Wordnet, Information Retrieval and Syntactic Dependencies) within a Random Forest learning model. We expanded this system with an Align and Differentiate based strategy, word embeddings and penalization, which showed 6.8% of improvement on the development set. However, we found that on the evaluation data for the 2016 STS shared task, the 2015 system outperformed our newer systems.
