Un- Relevance to ACL: Information Extraction is a core task in natural language processing, with the web serving as a rich source of information for constructing knowledge bases (KBs). A 2018 NAACL tutorial, “Scalable Construction and Rea-soning of Massive Knowlege Bases” (Ren et al., 2018), provided an overview of recent IE and KB research. information tent from text. This process of information extraction (IE) turns the unstructured extraction information embedded in texts into structured data, for example for populating a relational database to enable further processing. relation We begin with the task of relation extraction: ﬁnding and classifying semantic extraction Information extraction (IE) turns the unstructured information expressed in natural language text into a structured representation (Jurafsky and Martin, 2009) in the form of relational tuples consisting of a set of arguments and a phrase denoting a semantic relation between them: harg1; rel; arg2i.
