Using Wikipedia for Extracting Hierarchy and Building Geo‐Ontology - scientific work related to Wikipedia quality published in 2012, written by Quoc Hung Ngo, Son Doan and Werner Winiwarter.

Overview

Purpose – This paper aims to serves two main purposes: First, it seeks to provide an overview of the location hierarchy from the highest divisions (continents) to the lowest divisions (wards, villages) in reality and in the Wikipedia pages. Secondly, it aims to introduce an approach to building a geographical ontology from Wikipedia.Design/methodology/approach – The paper first reviews existing applications which extract information from Wikipedia and use it as a data resource to develop natural language processing tools. The paper also reviews the structure of Wikipedia pages which show the location's information. Based on the analysis, the paper then proposes an approach to extract location hierarchy as well as geographical characteristics for the geo‐ontology. The approach also rebuilds the relations between locations in the ontology.Findings – Existing location name systems are mainly based on probabilistic locations, which are mined from the data and they lack the administrative relations between loc...
