The LD4 Discovery Affinity Group was formed in 2019 to provide a space for discussion and sharing knowledge about the intersection of linked data and discovery. Recognizing the increasing focus or reference to AI in various library and discovery areas, this past year we started a series on AI, linked data, and discovery. We began by walking through fundamental concepts for machine learning and AI, and are working our way up to generative AI concepts, while also identifying overlap with linked data. In this LD4 conference session, in addition to providing a recap of the history of the group, we will also review topics and themes addressed in the series so far, and ask for input and suggestions regarding possible future topics.
