Hi @eugeniumegherea, to your first question - if you’re having issues extracting all the different forms of the airport names, you could try using lookup tables to help with that. As long as all the versions of an airport are annotated with the same value and extracted successfully, the synonym mapper should be able to map them. Could you post the examples you are using for an airport?
To your second question - it sounds like you need two different slots, but to fill them with the same entity (“airport”). What do your slot mappings look like for this form?
