1. A computer-implemented method, comprising: receiving a first profile in a system comprising one or more computers, wherein the first profile is for a first author, wherein the first profile links to one or more first documents, wherein the first author is an author of each of the one or more first documents; identifying by operation of the system, one or more second authors, wherein each of the one or more second authors is a co-author of one or more of the first documents; calculating by operation of the system and for each of the one or more second authors, a respective co-author score for the second author that is a measure of how connected the second author and the first author are as co-authors; ranking by operation of the system, the one or more second authors based on their respective co-author scores; associating by operation of the system, the one or more second authors with the first profile; receiving a request from a user to access a profile for the first author; and providing the first profile for presentation to the user, wherein, when presented to the user, the first profile includes a result list of retrieved and ranked resources associated with the first author and a listing of the one or more second authors in an order according to the ranking of the one or more second authors.

The method of claim 1 , wherein calculating a respective co-author score for each of the second authors comprises: determining a count of co-authored documents, wherein the co-authored documents are first documents that have both the first author and the second author as authors; determining a recency measure for each of the co-authored documents that measures how recently the co-authored document was written or published; determining a popularity measure for each of the co-authored documents; determining an author uniqueness measure for each of the co-authored documents from a total number of co-authors for the co-authored document; and calculating the co-author score based on the count of the co-authored documents, the recency measures, the popularity measures, and author uniqueness measures for each of the co-authored documents.
