Using Goi-Taikei as an Upper Ontology to Build a Large-Scale Japanese Ontology from Wikipedia - scientific work related to Wikipedia quality published in 2010, written by Masaaki Nagata, Yumi Shibaki and Kazuhide Yamamoto.
Overview
Authors present a novel method for building a large-scale Japanese ontology from Wikipedia using one of the largest Japanese thesauri, Nihongo Goi-Taikei (referred to hereafter as iGoi-Taikeii) as an upper ontology. First, The leaf categories in the Goi-Taikei hierarchy are semi-automatically aligned with semantically equivalent Wikipedia categories. Then, their subcategories are created automatically by detecting is-a links in the Wikipedia category network below the junction using the knowledge dene d in Goi-Taikei above the junction. The resulting ontology has a well-dene d taxonomy in the upper level and a ne-gra ined taxonomy in the lower level with a large number of up-to-date instances. A sample evaluation shows that the precisions of the extracted categories and instances are 92.8% and 98.6%, respectively.
