Thai place names in English: the dataset

This is the measured data behind the Phayan study Thai Place Names in English. The question, the counting rules and the predicted values were fixed before the first file was fetched, and every number in the article resolves to a row in the evidence ledger.

What is in it

FrameWhat it holdsRows
EOpenStreetMap objects in Thailand carrying a Thai name, an English name and a link to a Wikidata item that has its own Thai and English names1 364, of which 721 are comparable
WThai headwords carrying both a Paiboon and a Royal Institute romanisation17 274

Each row carries the two forms side by side, the kind of difference between them, and the Thai features that were declared before the measurement. The two frames sit in one file, told apart by a frame column.

Files

What it does not contain

No contributor is named. The count of distinct last editors behind each share is published; the account identifiers and the user names behind it are not, and no per-row hash of them was written anywhere.

Measurement date and identifier

Measured on 10 September 2026. No DOI has been minted for this dataset yet; the stable address is the one you are reading, and this page will carry the identifier once it exists.
