Recogito Tutorial: Annotating Tabular Data - pelagios/pelagios.github.io GitHub Wiki

After you upload the table of data, select “Automatic matching” and then “Places”. You will see a dialogue box that asks you one mandatory and two optional questions:

• Placename: In your spreadsheet identify which column lists the place-names. Then select that column from the drop down menu which Recogito provides.
• Coordinates: If your spreadsheet also stores coordinates data (latitude and longitude) in separate columns, you can tell Recogito where to find them. This will improve the disambiguation of places.
• Use Gazetteer: you may want to constrain the gazetteers to those that are historically or geographically relevant to the specific document you are annotating. See Annotation Preferences.

Recogito will then use one of its NER algorithms to match the place-names, but you will be able to check and modify each of them manually.
