Abstract: The present inventors devised systems, methods, interfaces, and software that can facilitate identification of law firms and/or legal professionals. One exemplary system receives queries from users regarding a legal topic and responds with a listing of attorneys or law firms that are associated with information ranking them based on their experience in handling matters related to the legal topic. The ranking information is based on links between attorneys and public legal documents, such as judicial opinions, court dockets, briefs, litigation documents, journal articles, patents, trademarks, and so forth that mention them by name.
