Publication places

• 1023 unique publication places; available for 477489 documents (99%).
• 0 ambiguous publication places; some of these can be possibly resolved by checking that the the synonyme list does not contain multiple versions of the final name (case sensitive).
• 2 unknown place names These terms do not map to any known place on the synonyme list; either because they require further cleaning or have not yet been encountered in the analyses. Terms that are clearly not place names can be added to stopwords; borderline cases that are not accepted as place names can be added as NA on the synonyme list.
• 137 discarded place names These terms are potential place names but with a closer check have been explicitly rejected on the synonyme list
• Conversions from the original to the accepted place names
• Unit tests for place names are automatically checked during package build

Top-20 publication places are shown together with the number of documents.

Publication countries

• 54 unique publication countries; available for 477488 documents (99%).
• 1 places with unknown publication country (0.1% of the unique places; can be added to country mappings)
• 0 potentially ambiguous region-country mappings (these may occur in the data in various synonymes and the country is not always clear when multiple countries have a similar place name; the default country is listed first). NOTE: possible improvements should not be done in this output summary but instead in the country mapping file.
