Abstract
Methods, systems, and apparatus, including computer program products for identifying original content. In one aspect a method is described that includes deriving a plurality of content pieces from a collection of documents, each content piece occurring in one or more documents in the collection of documents. Each document in the collection of documents is associated with a time and an author. A first document in the collection of documents is identified, the identified first document being the earliest document containing an occurrence of a first piece of content. A first author associated with the first document is ranked based on a number of documents that contain at least one occurrence of the content piece and that are associated with an author other than the first author.
