Bibliometric Impact Measures Leveraging Topic Analysis, Gideon S. Mann, David Mimno, Andrew Mccallum

Measurements of the impact and history of research literature provide a useful complement to scientific digital library collections. Bibliometric indicators have been extensively studied, mostly in the context of journals. However, journal-based metrics poorly capture topical distinctions in fast-moving fields, and are increasingly problematic in the context of open-access publishing. Recent developments in latent topic models have produced promising results for automatic sub-field discovery. The fine-grained, faceted topics produced by such models provide a more clear view of the topical divisions of a body of research literature and the interactions between those divisions. We demonstrate the usefulness of topic models …
