Open Information Extraction is a recent paradigm for machine reading from arbitrary text. In contrast to existing techniques, which have used only shallow syntactic features, we investigate the use of semantic features (semantic roles) for the task of Open IE. We compare TEXTRUNNER (Banko et al., 2007), a state of the art open extractor, with our novel extractor SRL-IE, which is based on UIUC’s SRL system (Punyakanok et al., 2008). We find that SRL-IE is robust to noisy heterogeneous Web data… CONTINUE READING
