Oracle Spatial 11g introduces the industry's first open, scalable, secure and reliable RDF management platform. Based on a graph data model, RDF triples are persisted, indexed and queried, similar to other object-relational data types. The Oracle 11g RDF database ensures that application developers benefit from the scalability of Oracle 11g to deploy scalable and secure semantic applications. Application areas include: * Life Sciences: Biological pathway analysis, discovery and enhanced search. * Defense & Intelligence: Data and content integration, reasoning and inference. * Enterprise Application Integration: Data and systems integration, semantic enterprise integration and semantic web services. * CRM/ERP: Supply chain integration, sourcing optimization and customer service automation.

ur patented Metatomix Platform for Life Sciences harnesses the power of semantic web standards and combines ontology-based modeling, middleware integration, business rules processing and advanced data visualization that delivers seamless unification and enrichment of disparate data sources (both structured and unstructured), makes the enriched information actionable and provides insights into the information that were previously unavailable.

Bloggers want... Blogging can be a business a hobby or a passion. Regardless of why you blog, it should be fun for you and engaging for your readers. Calais offers several tools that can improve your blog's tagging, incorporate great images and make your blog's contents more searchable. Calais for WordPress Meet Tagaroo, the Calais plugin for WordPress blogs. As you are writing your post, Tagaroo automatically analyzes it and suggests both tags and images from Flickr to enhance your post. You can select tags you like, incorporate them into your post, and then automatically search Flickr for images to complement your writing. Tagaroo has its own home, where you can read about it in more detail, download the plugin, and visit the forums. Calais for Drupal Drupal is clearly among the hottest content management systems out there. The folks at Phase2Technology have built a great Drupal module that makes Calais functionality available to the Drupal CMS platform. The module overview located in our Gallery will give you a quick overview of how to incorporate this tool into your Drupal installation. Riding the Semantic Wave with Yahoo If you're tuned in to the Semantic Web buzz, Yahoo's recent announcement that they will crawl websites and index semantic metadata is a big deal. Over time this will allow much more powerful and focused search capabilities - and we want you to be part of it. But there's a problem. Most bloggers don't have the tools or the time to create rich semantic metadata to identify the people, organizations, places and other items in their content. So we've built a simple tool that will do it for you.

Tamara Munzner Ph.D. dissertation, Stanford University, June 2000. Abstract *Visualization/graphing strategy for large semantic networks is described. Very technical.* Many real-world domains can be represented as large node-link graphs: backbone Internet routers connect with 70,000 other hosts, mid-sized Web servers handle between 20,000 and 200,000 hyperlinked documents, and dictionaries contain millions of words defined in terms of each other. Computational manipulation of such large graphs is common, but previous tools for graph visualization have been limited to datasets of a few thousand nodes. Visual depictions of graphs and networks are external representations that exploit human visual processing to reduce the cognitive load of many tasks that require understanding of global or local structure. We assert that the two key advantages of computer-based systems for information visualization over traditional paper-based visual exposition are interactivity and scalability. We also argue that designing visualization software by taking the characteristics of a target user's task domain into account leads to systems that are more effective and scale to larger datasets than previous work.

The blogosphere is the most explosive social network you'll never see. Recent studies suggest that nearly 60 million blogs exist online, and about 175,000 more crop up daily (that's about 2 every second). Even though the vast majority of blogs are either abandoned or isolated, many bloggers like to link to other Web sites. These links allow analysts to track trends in blogs and identify the most popular topics of data exchange. Social media expert Matthew Hurst recently collected link data for six weeks and produced this plot of the most active and interconnected parts of the blogosphere.

a few researchers but no solid examples I know a few people (especially some professors in the teaching-oriented universities) who are working on this technology. But as far as I know, they are individual experiments and no significant examples so far that are really exciting.

SemanticHacker.com is home of the TextWise SemanticHacker API and we're bold enough to call it the world's first open API for semantic discovery. Semantic discovery is a way to find information without knowing explicitly what you're looking for BUT "you know it when you see it." Semantic discovery does not punish you for using the wrong keywords. We built the API for clients and users to actively engage with our core technology - Semantic Signatures®. See our Semantic Signatures® in action on the right.

Case studies include descriptions of systems that have been deployed within an organization, and are now being used within a production environment. Use cases include examples where an organization has built a prototype system, but it is not currently being used by business functions.
