Before revision:  We describe the improvements we make in the dataset, and the new models proposed for this task. We compare the results of our new models with previous results, both on the labelled dataset and a larger unlabelled corpus. We end with a discussion on the characteristics of the results of our new models, followed by a conclusion. Our code and improved dataset are released under an open-source license on github .
After revision:  We describe the improvements we make in the dataset, and the old training data and methods: 735 thousand references in total. With these patent-publication links, follow-up research will further analyze which types of scientific work lead to inventions .
