Enabling Complex Wikipedia Queries - Technical Report

In this technical report we present a database schema used to store Wikipedia so it can be easily used in query-intensive applications. In addition to storing the information in a way that makes it highly accessible, our schema enables users to easily formulate complex queries using information such as the anchor-text of links and their location in the page, the titles and number of redirect pages for each page and the paragraph structure of entity pages. We have successfully used the schema in domains such as recommender systems, information retrieval and sentiment analysis. In order to assist other researchers, we now make the schema and its content available online.
