A Comparison of Approaches for Geospatial Entity Extraction from Wikipedia - scientific work related to Wikipedia quality published in 2010, written by Daryl Woodward, Jeremy Witmer and Jugal K. Kalita.
Overview
Authors target in this paper the challenge of extracting geospatial data from the article text of the English Wikipedia. Authors present the results of a Hidden Markov Model (HMM) based approach to identify location-related named entities in the corpus of Wikipedia articles, which are primarily about battles and wars due to their high geospatial content. The HMM NER process drives a geocoding and resolution process, whose goal is to determine the correct coordinates for each place name (often referred to as grounding). Authors compare results to a previously developed data structure and algorithm for disambiguating place names that can have multiple coordinates. Authors demonstrate an overall f-measure of 79.63% identifying and geocoding place names. Finally, authors compare the results of the HMM-driven process to earlier work using a Support Vector Machine.
