Open Calais Release 4.0 Open Calais Release 4.0 Presentation Transcript

  • Calais Thomson Reuters Calais Initiative: Calais 4.0 ~ January, 14, 2009 Thomas (“Tom”) Tague and Krista Thomas
  • Overview
    • Going to discuss five basic topics
      • What is Calais?
      • Why we’re doing it & what our goals are
      • How it works / What’s under the hood?
      • A few examples
      • Where it’s headed
  • Calais? What’s Calais? As seen from U.K & the Continent As seen from North America As seen by us
  • Calais? What’s Calais?
    • A semantic metadata generation service that extracts entities, facts and events from unstructured text
    • Creates linkages from extracted entities to linked data ecosystem
    • Provides a transportation layer for rich semantic metadata from producers to consumers
    • Details to follow….
  • Why We’re Doing It
    • Two simple answers:
      • Hyper-evolution of capabilities – better, faster, stronger
      • The walled garden content world
  • Our Goals / The Capabilities We Want to Deploy
    • Let’s state them here and then walk through why we have these goals
      • Derive semantic metadata from textual assets
      • Use that semantic metadata to create entry points into the linked data ecosystem
      • Provide a simple mechanism for the sharing of semantic metadata about textual content assets
  • 1: Semantics from Text: The Text Problem
    • People consume text
    • Most of it isn’t semantically enabled
    • Most of it won’t be semantically enabled
    • This isn’t about standards – microfromats vs RDFa vs whatever.
    • Why: Latency, cost and short shelf-life
  • 1: Semantics from Text: The Text Problem
    • Target areas where:
      • The economics don’t support metadata creation
      • The value of metadata is potentially high
      • The value of aggregated metadata is potentially extremely high
    Seconds Years Seconds Years Tweets Blogs News Scient. Pubs Great Novels Latency Shelf Life
  • 2: Getting from Text to the Linked Data Ecosystem
  • The Linked Data Cloud
  • 3: Semantic Metadata Transport Layer
    • I’m a content producer. We’ve loaded the car with rich semantic metadata
      • I’m sharing it within my four walls
      • How do I transport it to my consumers?
      • RSS / Atom, XML, Proprietary data feeds, Content API’s
  • How it Works – Under the Hood of Calais
  • How it Works – Under the Hood of Calais Calais Web Service ClearForest NLP Engine Rule Base Lexicons RDF Disambig. Engine Reference Data Assets Metadata Management Document Level Metadata Entity Level Linked Data and … Output Formatting Stat Tools
  • How You Can Use It – the SemHead version
    • Send unstructured text
      • Get back document categorization, entities, facts and events – with document and entity level URI’s
    • Syndicate Metadata
      • Send unstructured text
      • Share /syndicate the document GUID
    • Access Endpoints
      • Use entity level URI
      • Access entity level Linked Data endpoints & TR Content
  • Entities, Facts & Events

  • Calais progress to date
    • Launched in late January, 2008
    • 9,000 developers have joined OpenCalais.com
    • Approx. 1 million content ‘transactions’ per day
    • Delivered four major update releases
    • Lots of interesting apps
      • The Mail & Guardian Online ( http:// www.mg.co.za / )
      • www.powerhousemuseum.com
      • Gist.whistlehog.com
      • http://www.semanticproxy.com
  • Example: The Mail & Guardian Online, South African Newspaper
    • Using Calais to metatag new and historical articles, and:
      • Build an index or topics A-Z
      • Pull out automatic related articles or pictures
      • Create news alerts on companies or people
      • Pull up maps for the countries named in articles
      • Predict readers’ interests based on browsing habits
      • Create tag clouds, showing popular subjects, people, etc.
    Using Calais to optimize search and navigation; drive consumer engagement
  • Example: Gist - today’s news filtered by people, places & events GIST uses Calais to prioritize stories, rank newsmakers & reveal trends / reader demand. It automatically aggregates multiple news sources and slots them into topic.
  • Example: The Powerhouse Museum in Sydney Using Calais to tag historical archives & using tags as search terms
  • Example: IT Healthcare News Using Calais to surface ambient “related content”
  • Examples
    • Those are examples of first generation uses. Some of what we’re seeing in the pipeline:
      • Social Resume analysis
      • Investigative Journalism*
      • Museum metadata coalitions
  • Investigative Journalism FOIA Contract Documents Calais Web Service Company:Person FamilyRelation News Calais Web Service Company:Contract Company:Affiliation Big Fuzzy Graph
