The automatic extraction of information from unstructured sources has opened up new avenues for querying, organizing and analyzing data Information Extraction (IE) is the task of automatically extracting structured information from unstructured and/or semi-structured machine-readable documents. Information extraction systems attempt to pull out information from documents by filling out pre-defined templates. The information typically consists of entities and relations between entities like who did what to whom, where, when and how.
