Using Other Learner Corpora in the 2013 NLI Shared Task
Julian Brooke, Graeme Hirst · 2013
Our efforts in the 2013 NLI shared task focused on the potential benefits of external corpora. We show that including training data from multiple corpora is highly effective at robust, cross-corpus NLI (i.e. open-training task 1), particularly when some form of domain adaptation is also applied. This method can also be used to boost performance even when training data from the same corpus is available (i.e. open-training task 2). However, in the closed-training task, despite testing a number of new features, we did not see much improvement on a simple model based on earlier work. 1
