    • Nov. 17 2010 - S. Fermigier & O. Grisel, Nuxeo Towards semantic ECM: report on the IKS and Scribo projects Monday, November 22, 2010
    • Outline • Introduction to semantic technologies • Collaborative R&D within the Scribo and IKS projects • Fise & Apache Stanbol / Nuxeo Integration Monday, November 22, 2010
    • 1. Introduction to semantic technologies Monday, November 22, 2010

    • Historical perspective • From web 1.0: web of pages, aka the World Wide Web • To web 2.0: web of people and of participation, aka the Social Web • To web 3.0: web of data, of meaning and of connected knowledge, aka the Semantic Web Monday, November 22, 2010

    • A “layer cake” of technologies Monday, November 22, 2010
    • Linked Online Data in 2007 “Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/” Monday, November 22, 2010
    • 2008 “Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/” Monday, November 22, 2010
    • 2009 “Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/” Monday, November 22, 2010
    • 2010 “Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/” Monday, November 22, 2010
    • Good for Enterprise apps too! Diagram source: http://www.w3.org/2007/Talks/0130-sb-W3CTechSemWeb/ Monday, November 22, 2010
    • Key Enablers • Open Data and Linked Online Data • Advances in automatic content analysis (linguistics, image processing) • Computing power (Moore’s law + MapReduce) • Classical logic and classical AI Monday, November 22, 2010
    • The technologies and data are available, let’s put them to use! Monday, November 22, 2010
    • Semantic ECM Metadata Text Sound Tags Entities Image Relations Video Reasoning Content Meaning Monday, November 22, 2010
    • Goals for Semantic ECM (& Nuxeo) • Repurpose existing content • Improve search and collaboration • Make information contextual • Extract and use information from your content • Make your content smarter! Monday, November 22, 2010
    • Challenges • Extract meaning from content • Enrich content with knowledge • Enhance interaction with content thanks to added meaning Monday, November 22, 2010
    • Business value from semantic ECM • Efficiency gains: 20% to 90% (ex: in search, collaboration) • Effectiveness gains: better returns from your assets (ex: news and images from AFP) • Strategic edge: growth, value capture, new services, gain unfair strategic advantage (ex: vertical ontologies for CEVAs / CCAs) Monday, November 22, 2010
    • 2. SCRIBO and IKS Monday, November 22, 2010
    • • Project under the french FUI program, with 9 partners, and a budget of 4.7 M€ • Goal: to develop algorithms and collaborative tools for extracting knowledge from unstructured documents and images • Started in 2008, finishing in Dec. 2010, with results already integrated as a Nuxeo plugin Monday, November 22, 2010
    • • European project under the FP7, with 13 partners (6 SMEs) and a 8.5 M€ budget • Goal: create a semantic software “stack” that will be used by CMS vendors to add semantic features to their products • Started in Jan. 2009, will last until Dec. 2012 • First tangible result: FISE, already integrated in a Nuxeo plugin Monday, November 22, 2010
    • 3. Linking Semantic Entities Apache Stanbol - Nuxeo integration Monday, November 22, 2010
