		<pub:abstract><![CDATA[KG Cleaner is a framework to identify and correct errors in data produced and delivered by an information extraction system. These tasks have been understudied and KG Cleaner is the first to address both. We introduce a multi-task model that jointly learns to predict if an extracted relation is credible and repair it if not. We evaluate our approach and other models as instance of our framework on two collections: a Wikidata corpus of nearly 700K facts and 5M fact-relevant sentences and a collection of 30K facts from the 2015 TAC Knowledge Base Population task. For credibility classification, we find that parameter efficient, simple shallow neural networks can achieve an absolute performance gain of 30 F1 points on Wikidata and comparable performance on TAC. For the repair task, significant 
performance (at more than twice) gain can be obtained depending on the nature of the dataset and the models.]]></pub:abstract>
