This tutorial teaches the audience about characteristics, advantages and limitations of Wikipedia relative to other existing, human-curated resources of knowledge; and derivative resources, created by converting semi-structured content in Wikipedia into structured data. The tutorial examines the role of Wikipedia and its derivatives in text analysis and retrieval. Examples of text analysis tasks, which take advantage of Wikipedia, are coreference resolution, word sense and entity disambiguation and information extraction. In information retrieval, a better understanding of the structure and meaning of queries enables a better match of queries against documents, and retrieval of knowledge panels for queries asking about popular entities.
