Outline

• The real Semantic Web
• Vocabulary Markup Language (Voc-ML)
• Namespace registry
• Schema
• Services definition
• Voc-ML applications

The problem IS search!

• Data values, NOT just data structures are needed.

Soergels SemWeb Proposal

• System of integrated access to data on concepts
  and terminology.
• Bring together variety of sources that exist
  largely in separate worlds, including
  dictionaries, thesauri, classification schemes,
  etc.
• Federated system with multiple collaborators.
• Common interface to all concept terminology
  knowledge bases on the Internet.

distributed ontological resources. (April 1998)

The Real Semantic Web

• Namespace for uniquely identifying a semantic
  scheme each concept within each scheme.
• Broad template or conceptual schema for holding
  all types of semantic information specifying
  relationships among them.
• Definitions of services for interacting with the
  System.

Schema Vocabulary Markup Language (Voc-ML)

• XML schema for the Semantic Web.
• Broad template for structured representation of
  semantic schemes.
• Z39.19-1993 and ISO 2788
• Dublin Core metadata
• Tags and syntax for uniquely identifying each
  concept
• Typed relationships (hierarchical, associative,
  etc.)
• Host agency Networked Knowledge Organization
  Systems

Application Visual vocabulary editor
Portability. Voc-ML input/output. Utilities to convert outline, spreadsheet, directory to Voc-ML
Manage namespace unique IDs (not just a list of labels). Enforce namespace and ID uniqueness.
Allow polyhierarchy (membership in multiple classes). Copy paste term to additional parent.
Allow typed equivalents. Add/edit equivalents with pre-defined types.
Easy to use. File manager style hierarchy display. Drag drop/cut paste terms and their children. Undo. Right-click functions.

Application Manage product taxonomies
Organize (and reorganize) product classes for diverse purposes Drag and drop editing Preserve unique ID within namespace
Allow products to have many aliases Alternates associated with unique ID
Allow products to exist in more than one class Polyhierarchy (to allow multiple parents)
Map products across multiple taxonomies Relationships across different namespaces (e.g. linked parallel hierarchies in different languages
Generate and maintain linkages to associated documentation Associate metadata labels as well as namespace with unique ID

Application Search query intermediation
Map content to controlled vocabulary (thesaurus, etc.) Associate metadata labels.
Control exactly what is indexed (metadata not just full text) and when. Deploy metadata direct to search engine without spidering.
Deploy controlled vocabulary (thesaurus, etc.) to search engine. Re-direct user queries to thesaurus, and return expanded query based on rules.
