<cite>PRA-SVO</cite> and PRA-VS are the systems proposed in <cite>(Gardner et al., 2013)</cite> and (Gardner et al., 2014) respectively, where the KB graph is augmented with edges mined from a large subject-verb-object (SVO) triple corpus. In these two systems, only new edges are added over the fixed set of nodes, and the augmentation happens in a batch, offline setting. In contrast, PRA-ODA, the method proposed in the paper, also expands the set of nodes through bridging entities, and performs the augmentation in an on-demand manner.
