Hello! My goal is to take specific journal articles from pubmed using the pubmed document parser node, and to extract the location data from each of the journals so that I can map them geographically to understand where certain types of research is being done. I am having problems finding the location data even though the pubmed parser node is able to differentiate the journals based on location key words.
suggest you have a look at the Palladian nodes, especially the geo category. The Location Extractor should be very helpful for you:
It’ll extract and disambiguate location mentions in unstructured text (no need to do any text processing beforehand) and map them to latitude/longitude coordinates. It works for continent, country, city, zip code, street, street number, political/administrative units, regions, POIs, landmarks, and more.
I recently wrote about a use case here on the forums:
