    Seven Arguments for Semantic Technologies Seven Arguments for Semantic Technologies Presentation Transcript

    • Seven Arguments forSemantic Technologies Michael K. Bergman February 24, 2013
    • Summary Points© Copyright 2013. Structured Dynamics LLC 2
    • Knowledge-based Findability  A “unifier” of search:  structured + semi-structured + unstructured data  find + discover + navigate  SQL + SPARQL + full-text  “dial-in” search results  Global faceting:  types of things  relationships of thing  Relationships bring context  Explodes keyword boundaries:  concept enrichment  meaning and many ways to describe things  multi-linguality  inference© Copyright 2013. Structured Dynamics LLC 3
    • Ability to Do More – Classic IA© Copyright 2013. Structured Dynamics LLC 4
    • Going Beyond Content and Context  Convertibility  single data representation model  the “universal solvent”  Data interoperability  Semantic annotation and tagging:  concepts – OBIE  entities – NER  semantic injection  Understood equally by machines + humans  Computability  Analysis  Superior performance  Semantic publishing© Copyright 2013. Structured Dynamics LLC 5
    • The Knowledge Graph  Built from simple (“triple”) assertions:  easily understood  easily corrected  concepts and many ways to speak of them  can capture rich relationships  rich ways to organize  Based on logic:  may be reasoned over  testable for coherence  Supports unique capabilities:  graph traversal  graph analysis© Copyright 2013. Structured Dynamics LLC 6
    • Control Shifts to the Business  Major driver is the ontology, structure of information  Content is separated:  from presentation  from applications  SMEs and knowledge workers now:  model the business, workflows  extend structure  expand concepts, meaning  author content, manage datasets  IT now shifts to:  developing generic applications (“ODapps”)  stack deployment and maintenance  security, content versioning and backups© Copyright 2013. Structured Dynamics LLC 7
    • Adaptive, Robust Structures  The right data representation model:  RDF v RDBMs  open world v closed world assumption  representation = knowledge + access  Integrating heterogeneous information:  syntactic  structure (“granularity mismatch”)  semantic  More effective HCI (human-computer interface):  separation of content and presentation  templates  ontology-driven (generic) applications© Copyright 2013. Structured Dynamics LLC 8
    • Much Reduced Costs  Leverage existing information assets  Single representation of schema  Use of generic, ontology-driven tools  Extendable without re-architecting  Reduced errors  Higher quality information in context  Lower deployment and set-up costs +  Lower maintenance and extension costs  average 1 – 2 orders of magnitude less© Copyright 2013. Structured Dynamics LLC 9
    • Domain Rationale (biomedical example)  Veritable explosion in data (“Big Data”)  Veritable explosion in new concepts, new knowledge  Rich, layered, complex relationships:  many disciplines and sub-disciplines  many informational perspectives  many players  much varied terminology  fit with electronic health records (EHR)  Strong, existing support for semantic technologies:  more than 250 extant ontologies, ontology groups  the OBO Foundry  the National Center for Biomedical Ontology  major emphasis of US National Institutes of Health and its National Library of Medicine© Copyright 2013.
