Systems and methods for matching an advertisement to a video
InactiveUS20110251896A1Accurate signatureAdvertisementsSpecific information broadcast systemsHyperlinkScene segmentation
Systems and methods for automatically matching in real-time an advertisement with a video desired to be viewed by a user are provided. A database is created that stores one or more attributes (e.g., visual metadata relating to objects, faces, scene classifications, pornography detection, scene segmentation, production quality, fingerprinting) associated with a plurality of videos. Supervised machine learning can be used to create signatures that uniquely identify particular attributes of interest, which can then be used to generate the attributes associated with the plurality of videos. When a user requests to view an on-line video having associated with it an advertisement, an advertisement can be selected for display with the video based on matching an advertiser's requirements or campaign parameters with the stored attributes associated with the requested video, with the user's information, or a combination thereof. The displayed advertisement can function as a hyperlink that allows a user to select to receive additional information about the advertisement. The performance or effectiveness of the selected advertisements can be measured and recorded.

Parallel approach to XML parsing
InactiveUS20090089658A1Flexible performanceImprove readabilityNatural language data processingSpecial data processing applicationsMulticore architectureSchema for Object-Oriented XML
A language for semi-structured documents, XML has emerged as the core of the web services architecture, and is playing crucial roles in messaging systems, databases, and document processing. However, the processing of XML documents has a reputation for poor performance, and a number of optimizations have been developed to address this performance problem from different perspectives, none of which have been entirely satisfactory. Parallel XML parsing leverages the growing prevalence of multicore architectures in all sectors of the computer market, and yields significant performance improvements. The design consists of an initial preparsing phase to determine the structure of the XML document (or other data document), followed by a full, parallel parse. The results of the preparsing phase are used to help partition the XML document for data parallel processing. The parallel parsing phase is, for example, a modification of the libxml2 XML parser, which demonstrates that the approach applies to real-world, production quality parsers. Empirical study shows the parallel XML parsing algorithm can improve the XML parsing performance significantly and scales well.
