Semantic Supercomputing Reaps Competitive Advantage from Patent Data
Since the first patent was issued for a Venetian statue in 1471, 60 million patents have been awarded around the world, with four million patents actively in force today worldwide. And 800,000 new inventions are registered every year. While the data is public, current search tools are inconvenient and inadequate to the needs of professionals. Semantic supercomputing techniques are helping researchers tackle this difficult challenge.

Video White Paper: Architecting a Better Network Storage Solution
Sponsored Content
BlueArc's Titan architecture represents an evolutionary step in file servers by creating a hardware-based file system that can scale bandwidth, IOPS, and overall data capacity well beyond conventional software-based devices. With its ability to virtualize a massive storage pool of up to four usable petabytes of tiered storage, Titan can scale with growing data requirements, offering a competitive advantage for businesses, researchers, or other enterprises seeking to better manage data growth while still ensuring optimal performance.
