Transcript of Open Calais Release 4.0
CalaisThomson 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
1. Derive semantic metadata from textual assets
2. Use that semantic metadata to create entry points into the linked data ecosystem
3. 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

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 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

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:1. Build an index or topics A-Z2. Pull out automatic related articles or pictures3. Create news alerts on companies or people 4. Pull up maps for the countries named in articles5. Predict readers’ interests based on browsing habits 6. 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
