Phylomemetic Patterns in Science Evolution—The Rise and Fall of Scientific Fields

We worked with David Chavalarias on an automated method for the bottom-up reconstruction of the cognitive evolution of science modeled as lineage relationships between scientific fields. We refer to these dynamic structures as phylomemetic networks or phylomemies, by analogy with biological evolution; and … Continue reading
