💡Concepts

These are the original OpenAlex Concepts, which are being deprecated in favor of Topics. We will continue to provide these Concepts for Works, but we will not be actively maintaining, updating, or providing support for these concepts. Unless you have a good reason to be relying on them, we encourage you to look into Topics instead.

Our legacy Concepts uses a system adapted from MAG to assign multiple concepts to works using their titles and abstracts. You can learn more about these concepts and how they are assigned in our technical documentation here.
