Does anyone know what google news uses for their clustering algorithm?

Question

curious if anyone has insight into what algorithm google news uses to group like stories together? k-means? or something custom?

Answer 1

When Google launched Google News, they used to put a small section about the algorithms they used to group on "About Google News" page, there was a mention of "An advanced Bayesian Network" and some other algorithms(no other algorithms names were mentioned!). That paragraph is now absent from the same page.
