The Recommendation API offers users recommendations for items available in Europeana based on other items, entities or galleries (ie. user sets). It uses a technology from machine learning (a subfield in artificial inteligence), more specifically vector embeddings, to compute similarity between information resources based on a selective number of parameters/dimensions.
This API supports the recommendation functionality on the Europeana website and can be found next to the pages where these resources are available such as the Item Page, Entity Page and Gallery Page. It is only available for logged-in users on the Europeana Website but is available for all users at the API unless the resource has restricted access such as private user sets (galleries).
