Number of Archaeological Site Reports by Prefectures
In the process of creating the Word Map, if there are not enough archaeological site reports (PDF format) from individual prefectures, the Word Map is not created. This is due to the fact that we want to avoid results affected by the statistical bias. Therefore, the Word Map is only created if the archaeological site reports that are in the PDF format (Report Type a01from Comprehensive Database of architectural site) has more than 300 site. Bulletin articles and materials from field briefings, are not included in the number of site reports.
