Identification of research hypotheses and new knowledge from scientific literature

Table 6 A comparison of the Knowledge Type results produced by our classifier against the results of the most directly comparable work

To enable a more direct comparison, we have also provided our results when using a SVM (the classifier used by Miwa et al.) with our features
