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.

Abstract: A runtime system implemented in accordance with the present invention provides an application platform for parallel-processing computer systems. Such a runtime system enables users to leverage the computational power of parallel-processing computer systems to accelerate/optimize numeric and array-intensive computations in their application programs. This enables greatly increased performance of high-performance computing (HPC) applications.

Abstract: Disclosed herein is a method, computer system and computer program product for identifying a writing system associated with a document image containing one or more words written in the writing system. Initially, a document image fragment is identified based on the document image, wherein the document image fragment contains one or more pixels from one or more of the words in the document image. A set of sequential features associated with the document image fragment is generated, wherein each sequential feature describes one dimensional graphic information derived from the one or more pixels in the document image fragment. A classification score for the document image fragment is generated responsive at least in part to the set of sequential features, the classification score indicating a likelihood that the document image fragment is written in the writing system.
