Item Approaches for Automatically Enriching Wikipedia(AAAI, 2010-06-11) Syed, Zareen; Finin, TimWe have been exploring the use of Web-derived knowledge bases through the development of Wikitology - a hybrid knowledge base of structured and unstructured information extracted from Wikipedia augmented by RDF data from DBpedia and other Linked Open Data resources. In this paper, we describe approaches that aid in enriching Wikipedia and thus the resources that derive from Wikipedia such as the Wikitology knowledge base, DBpedia, Freebase and Powerset.Item Using Wikitology for Cross-Document Entity Coreference Resolution(AAAI, 2009-03-23) Finin, Tim; Syed, Zareen; Mayfield, James; McNamee, Paul; Piatko, ChristineWe describe the use of the Wikitology knowledge base as a resource for a variety of applications with special focus on a cross-document entity coreference resolution task. This task involves recognizing when entities and relations mentioned in different documents refer to the same object or relation in the world. Wikitology is a knowledge base system constructed with material from Wikipedia, DBpedia and Freebase that includes both unstructured text and semi-structured information. Wikitology was used to define features that were part of a system implemented by the Johns Hopkins University Human Language Technology Center of Excellence for the 2008 Automatic Content Extraction cross-document coreference resolution evaluation organized by National Institute of Standards and Technology.
