1 Information Integration Intelligence Solutions Envisioning Semantic Web Technology Solutions for the Arts Semantic Web and CIDOC CRM Workshop Ralph Hodgson, CTO, TopQuadrant National Museum of the American Indian Washington, DC October 25, 2009 What can Semantic Web Technologies do for the Arts Need Strategy Solution Outcome
2 Ralph Hodgson Introductions co-founder and CTO of TopQuadrant, first US-based company specializing in semantic technology Prior to starting TopQuadrant in 2001, held executive consulting positions at IBM Global Services as a founding member of Portal Practice and Object Technology Practice. Recent books: Adaptive Information, published by John Wiley in 2004, and Capability Cases: A Solution Envisioning Approach, published by Addison-Wesley in July In my spare time, a Pastel Artist and Sculptor Copyright 2009 TopQuadrant Inc. Slide 1

4 Key Benefits of Semantic Technology Information Integration Mapable terms to build consistent & extensible vocabularies. Integrate models with both structured and unstructured data Search and Analysis Semantic relationships between data enable powerful queries that leverage knowledge organized by people to deliver specific answers in a highly scalable fashion Non-programmers can connect, search and analyze data Application Longevity and Flexibility Future-proof applications (30, years) by enabling knowledge workers to participate in model-based application development Copyright 2009 TopQuadrant Inc. Slide 3
5 Semantic Web Layer Cake OWL = Web Ontology Language A language for describing a domain of interest Classes, Instances and properties of things, relationships between things, A standard defined by the World-Wide Web Consortium (W3C) How does it relate to XML? OWL can be serialized in XML and N3 OWL is built on the Resource Description Framework (RDF) OWL constructs allow us to say things that XML Schema does not allow Copyright 2009 TopQuadrant Inc. Slide 4
6 Why OWL - the Ontology Web Language? XML is document-based not model-based Container Hierarchies - weak support for relationships Weak support for aggregation (combining documents) Schema Limitations UML is Object-Based Restricted Type System Weak on Relationships Weak notion of identity Metamodel (Schema) is in a different language OWL is Set-Based Expressive Type System Strong on Relationships Strong notion of identity Graphs not Trees Metamodel is in the same language Copyright 2009 TopQuadrant Inc.

19 Copyright TopQuadrant Inc., Solution Envisioning for Knowledge Enablement, slide 18 TopQuadrant Capability Case: Recommender SolutionStory: Personalized TV (PTV) A slide from a past presentation Filter information for people needing to monitor and assess large volumes of data for relevance, volatility or required response. The volume of targeted information is reduced based on its relevance according to a role or interest of the end user. Sensitive information is filtered according to the "need to know". Personalized News and TV Program Guide Personal TV Advisor uses a combination of model-based case based reasoning (CBR) and collaborative filtering technology to identify relevant information. Users set up their initial profiles and preferences based on the categories in a model of the entertainment domain. System continuously improves and refines its program recommendations learning from the feedback of the individual users (thumbs up/thumbs down function), as well as others who have similar tastes. Content can be delivered through a portal or via wireless interface.

25 Copyright TopQuadrant Inc., Solution Envisioning for Knowledge Enablement, slide 24 TopQuadrant CapabilityCase: Expert Locator SolutionStory: Boeing Expert Locator A slide from a past presentation Provide users with convenient access to experts in a given area who can help with problems, answer questions, locate and interpret specific documents, and collaborate on specific tasks. Knowing who is an expert in what can be difficult in an organization with a large workforce of experts. Expert Locator could also identify experts across organizational barriers. Exploiting a Thesaurus-Based Semantic Net for Knowledge-Based Search Boeing has a large workforce of experts making it hard to find the right person. This web-based system returns details on potentially appropriate experts. The Boeing technical thesaurus was harnessed to create expert profiles. Boeing Technical Libraries already had made a considerable investment to develop by hand a technical thesaurus in the form of a semantic network. It incorporates 37,000 concepts with an additional 19,000 synonym concept names, and 100,000 links including broaderterm, narrowerterm, and relatedterm.
