Vasia Kalavri commented on FLINK-3879:
--------------------------------------

Hey [~greghogan], since FLINK-2044 was updated to provide convergence and return both scores, do we still need this issue?

> Hyperlink-Induced Topic Search (HITS, also "hubs and authorities") is presented in [0] and described in [1].
> "[HITS] is a very popular and effective algorithm to rank documents based on the link information among a set of documents. The algorithm presumes that a good hub is a document that points to many others, and a good authority is a document that many documents point to." [https://pdfs.semanticscholar.org/a8d7/c7a4c53a9102c4239356f9072ec62ca5e62f.pdf]
> This implementation differs from FLINK-2044 by providing for convergence, outputting both hub and authority scores, and completing in half the number of iterations.
