For now, the solution appears to be to retrain the model using datasets in your domain. This is a great primer on classical text summarization. I covered text summarization a couple of months ago during a DeepCrawl webinar. At that time the PreSumm researchers released an earlier version of their work focused only on extractive text summarization.

Deep learning & XgBoost: Winning it hands down!

According to Wikipedia, deep learning (deep structured learning, hierarchical learning or deep machine learning) is a branch of machine learning based on a set of algorithms that attempt to model high-level abstractions in data by using multiple processing layers, with complex structures or otherwise, composed of multiple non-linear transformations. Deep learning is sometimes defined as the intersection between machine learning and artificial intelligence. Many articles on deep learning can be found here.
