SPIN: An object-oriented framework for business rules using SPARQL – SemTech 2009 Video

Holger Knublauch
Vice President

The current generation of Semantic Web languages is well suited to link data and to define domain concepts and relationships. However, real-world applications that operate on those linked data models typically need higher expressivity than what is provided by OWL and RDF Schema alone. SPIN is an open-source framework that supports the use of SPARQL to define business rules and constraint checks on Semantic Web models with object-oriented modeling techniques. This simple yet powerful mechanism makes it possible to define self-describing domain models that can then be used by generic software components such as user interface renderers, schema mappers and workflow engines. Instead of hard-coding behavior in languages like Java, SPIN makes it possible to declaratively define complex business rules and processes. SPIN can also be used to define new higher-level modeling languages with built-in semantics.

This talk:

  • Sets the stage with a quick review of SPARQL (incl. CONSTRUCT keyword)
  • Introduces SPIN as a mechanism to attach SPARQL queries to class definitions
  • Shows how to define new SPARQL functions and reusable query templates with SPIN
  • Demonstrates the use of SPIN for tasks ranging from unit conversion to computer games
  • Shows how the ideas of SPIN give rise to a new software development paradigm around self-describing linked data models

After a period of caution about the viability of semantic technologies, investors seem more willing to fund semantic start-ups right now. And even with the economy in distress, semantics is managing to create excitement amongst the VCs. Semantic search has been hot for a couple of years – the possibility of finding the next Google being just too enticing – but the focus seems now to be shifting to enterprise and consumer apps where as Jim Hendler famously said "a little semantics goes a long way." Money is going into enterprise software, such as business intelligence tools, and innovative consumer apps based around social networks, smarter information filtering and productivity enhancement.

So what do the VCs want to see in the business plans for semantic start-ups now? Are there still plenty of good opportunities out there for entrepreneurs or have the best ideas already claimed their share of available capital?

This moderated panel discusses "semantic advertising" in the market today, with representatives from:

* An ad network using semantic technology (Peer39)
* a company using semantic technology to dynamically generate advertising content (Dapper)
* A company using semantic technology to dynamically feed ad content on a mobile platform (Expert System)
* an expert in advertising and former CEO of the Interactive Advertising Bureau (Greg Stuart)

The focus of this session is to give business people and technologists an understanding of how semantic technology is being used in online advertising today. This is a broad survey of the different ideas labeled as "semantic advertising" — presented by the people leading those initiatives — both to see what they have in common and how they’re different.

Every month, the Semantic Web Gang podcast brings together a team of researchers, practitioners and managers to share their views on topical developments in the semantic technology space. In a departure from the regular telephone conversation, June’s Gang finds host Paul Miller together on stage with Gang regulars Greg Boutin, Mills Davis, Leigh Dodds, Alex Iskold and Peter Mika and special guest Tony Shaw (Semantic Universe). We take a typical Gang look back over the Semantic Technology Conference, discussing our impressions and listening to those of our audience. Watch this video to see the Gang in action, to hear their opinions, and comment below to contribute your own views.

Panel: Linked Open Data – SemTech 2009 Video

The "data commons" is a cornerstone of the semantic web vision. The Linked and Open Data movements are progressing beyond the early adopter phase and preparing to cross the chasm. Enough experience now exists to reflect on how this data set is being used, how useful it is, and where we can take it from here. Beyond the basics, the panel will discuss issues such as quality of service, stability, and longevity. They’ll also explore the evolution of the semantic web with a particular emphasis on modes of data use, reuse and aggregation.

KEYNOTE: Semantics at The New York Times – SemTech 2009 Video

The first semantic search system for The New Times was released in 1913 and was available bound in either paper ($6) or cloth ($8). In the 96 years since the advent of The Historical Index to The New York Times, semantic technology has become central to The New York Times’ daily operations and the focus of much internal research and development.

KEYNOTE: The Game Changer: Siri, a Virtual Personal Assistant – SemTech 2009 Video

We are beginning to see a new interaction paradigm for the web: the Virtual Personal Assistant (VPA). A VPA is task focused: it helps you get things done. You interact with it in natural language, in a conversation. It gets to know you, acts on your behalf, and gets better with time. The VPA paradigm builds on the information and services of the web, with new technical challenges of semantic intent understanding, context awareness, service delegation, and mass personalization.

The mainstream adoption of Web 2.0 technologies – from RSS feeds to social networks – is hastening the demise of the portal. With each new face on Facebook, and each new Twitter account, our once routine habits and traffic patterns shift. This wave of change in the way we consume, transact and interact on the Web is dis-intermediating ‘destination’ sites of all kinds. Our once centralized content has been atomized.
