Populating Knowledge Base (KB) with new knowledge facts from reliable text re- sources usually consists of linking name mentions to KB entities and identifying relationship between entity pairs. How- ever, the task often suffers from errors propagating from upstream entity linkers to downstream relation extractors. In this paper, we propose a novel joint infer- ence framework to allow interactions be- tween the two subtasks and find an opti- mal assignment by addressing the coher- ence among preliminary local predictions: whether the types of entities meet the ex- pectations of relations explicitly or implic- itly, and whether the local predictions are globally compatible. We further measure the confidence of the extracted triples by looking at the details of the complete ex- traction proc...
