Additionally we give our post hoc run 2a, performed without a minimal feature count threshold of 3 and bi-normal feature selection (20,000). Our best post hoc run 6 uses bigrams (B) and syntactic features (S). Features considered are W (bag of words), M (MeSH), P (PPIscore), B (bigrams), S (syntactic) - for a detailed description see page 3.
