We believe that the enterprise ontology will become a cornerstone in many information systems in the future. In general terms, an ontology is an organization of a body of knowledge or, at least, an organization of a set of terms related to a body of knowledge. At the time of this writing almost no enterprises in North America have a formal enterprise ontology. Yet we believe that within a few years this will become one of the foundational pieces to most information system work within major enterprises. In this paper, we will explain just what an enterprise ontology is, and more importantly, what you can expect to use it for and what you should be looking for, to distinguish a good ontology from a merely adequate one.

I will discuss how RSS and its taxonomy module can be used as a central format to carry metadata collected in a classical news format, such as XMLNews-Story, to RDF or relational databases and XML Topic Maps. Readers should have basic familiarity with RSS and RDF, and a little topic maps knowledge would also help.

The Role of Semantic Web in Web 2.0: Partner or Follower? Currently, the web phenomenon that is driving the best developers and captivating the best entrepreneurs is Web 2.0. Web 2.0 encompasses some of today's most exciting web-based applications: mashups, blogs/wikis/feeds, interface remixes, and social networking/tagging systems. Although most Web 2.0 applications rely on an implicit, lightweight, shared semantics in order to deliver user value, by several metrics (number of startups funded, number of "hype" articles in the trade press, number of conferences), Web 2.0 technologies are significantly outdistancing semweb technologies in both implementation and mindshare. Hackers are staying up late building mashups with AJAX and REST and microformats, and only rarely including RDF and OWL. This panel will consider whether semantic web technology has a role in Web 2.0 applications, in at least the context of the following areas: 1. Web 2.0 and Semantics: What unique value can semantic web technologies supply to Web 2.0 application areas? How do semantic web technologies match up with the semantic demands of Web 2.0 applications? 2. Semantics and Web "Ecosystems": Web 2.0 applications often strive to build participatory ecosystems of content that is supplied and curated by their users. Can these users effectively create, maintain, map between, and use RDF/OWL content in a way that reinforces the ecosystem? 3. Semantic Web in Practice: Does semantic web technology enable the cost-effective creation of Web 2.0 applications that are simple, scalable, and compelling for a targeted user community? Can semantic web technology genuinely strengthen Web 2.0 applications, or will it just be a footnote to the Web 2.0 wave?

Abstract from downloadable PDF: Data on the Semantic Web is semi-structured and does not follow one fixed schema. Faceted browsing is a natural technique for navigating such data, partitioning the information space into orthogonal conceptual dimensions. Current faceted interfaces are manually constructed and have limited query expressiveness. We develop an expressive faceted interface for semi-structured data and formally show the improvement over existing interfaces. Secondly, we develop metrics for automatic ranking of facet quality, bypassing the need for manual construction of the interface. We develop a prototype for faceted navigation of arbitrary RDF data. Experimental evaluation shows improved usability over current interfaces.

[Sample clip]: For two systems to communicate they must commit to a common ontology. It doesn't matter how elegant or clever your ontology is, if no one else shares it, you don't participate in anything broader than your own ontology...

This diagram depicts a spectrum of information sharing capabilities. Moving from lower right to upper left of the diagram, we see that more expressive forms of metadata and semantic modeling encompass the simpler forms, and extend their capabilities. From bottom-to-top, the amount, kinds, and complexity of metadata and modeling increases. From left-to-right, capabilities for intelligent search, retrieval, discovery of relevant information, question answering, and autonomous action advance.

Semantic technologies have become central to a broad range of research and development initiatives. This diagram visualizes the intersections of four major development themes in the semantic wave: networking (e.g., semantic web, grid & p2p), content (e.g., knowledge extraction, semantic enhancement, executable content, semantic search), services (e.g., composite applications, semantic web services), and cognition (e.g. semantic UI, knowledge computing, intelligent agents).

The challenge that the Yahoos and Microsofts of the world have is that they are still beholden to the older corporate model of the world, and tend to denigrate their user generated content as being so much fluff. Thus when the Web 2.0 explosion occurred, these companies were frankly caught flat-footed … they were too busy servicing their corporate clients to realize that the real activity was going on in the apparent fluff - My Space, YouTube, Flickr, and so forth.

We have a limited “Semantic Web” appearing without the complex technologies that have been developed for it. Will the trend continue? Can it, using existing technologies, or will developers eventually ‘find’ RDF, OWL and SPARQL? Should the appearance and popularity of these applications give Semantic Web proponents hope that the real thing is coming, or do they give Semantic Web opponents valid ammunition against unnecessary complexities?

Not long after he invented and unleashed the World Wide Web, Tim Berners-Lee realized that the limit to the effectiveness of the World Wide Web would be that while billions of documents could be linked and indexed, they relied on human interpretation to do anything with them. In the mid-nineties he began an initiative to promote research and standards under the banner of “the Semantic Web.”

The Semantic Technology Conference (SemTech) enters its third year as the pre-eminent meeting place for the growing community of developers, entrepreneurs, technology architects and researchers who are building software and systems based on semantic technologies. The previous SemTech event attracted over 600 people from more than 20 countries and attendance is expected to be even larger in 2007. The Call for Papers for 2007 has just been issued and we welcome a variety of presentation proposals - both business and technology focused - from all communities. If you have a good story or case study that relates your experience and success in working with semantic technology then we invite you to make a proposal for the conference. The deadline for speaking proposals is December 18, 2006.

There's a lot of money to be made from telling healthy people they're sick. Some forms of medicalising ordinary life may now be better described as disease mongering: widening the boundaries of treatable illness in order to expand markets for those who sell and deliver treatments. 1 2 Pharmaceutical companies are actively involved in sponsoring the definition of diseases and promoting them to both prescribers and consumers. The social construction of illness is being replaced by the corporate construction of disease.

Medical protocols for treating many diseases, disorders, and conditions. Includes herbal, allopathic, and pharmacological approaches. Most medical specialties are covered, with guidelines at the "family doctor" level.

A user with an XFN Friendly blog, blogroll, or web site, can use that site as a nexus for linking together all their otherwise disparate and isolated social networking sites, by linking from those sites to their blog, and then linking from their blog to their particular page(s) on each such centralized social networking site. XFN complements and interoperates with a plethora of services and technologies. This document explains how to use XFN with these services and technologies. In addition, guidelines and suggestions are provided for developers wishing to aggregate and merge explicit XFN relationships and implicit XFN relationships determined from centralized social networking sites. WordPress has built-in support for XFN...

Conjugated linoleic acid is a collective term for a mixture of isomers of the dietary fatty acid linoleic acid. It is found in milk and dairy products and the meat of ruminant animals. Like linoleic acid, conjugated linoleic acid has 18 carbon atoms, but the two double bonds are found in various cis and trans formations. CLA is believed to possess anti-atherogenic properties, to modulate lipid and glucose metabolism (including insulin sensitivity), and to influence body composition although it appears that the individual isomers of CLA may exert different effects. Similarly, the n-3 polyunsaturated fatty acids (PUFAs) show positive effects on energy metabolism and insulin resistance.

One of the most important things a database needs is a key, or more precisely a Primary Key. This is a unique identifier for a row and is needed to be able to access data in a table. In Core Data this is taken care of automatically, however you will have to deal with them yourself in other databases. A Primary Key can be made up of more than one field, e.g. customer name and phone number, in which case it is a Concatenated Key. A Foreign Key is used when linking two tables together in a relationship. A Foreign Key is simply a Primary Key from another table, allowing you to associate elements from one table to another. For example, each sale would have a foreign key “customer id”, which would relate to the customer who purchased goods in the sale.

“Are you my friend? Yes or no?” This question, while fundamentally odd, is a key component of social network sites. Participants must select who on the system they deem to be ‘Friends.’ Their choice is publicly displayed for all to see and becomes the backbone for networked participation. By examining what different participants groups do on social network sites, this paper investigates what Friendship means and how Friendship affects the culture of the sites. I will argue that Friendship helps people write community into being in social network sites.
