BBC News [Static Publishing]

Static News Architecture

BBC CPS/CMS Asset Authoring

BBC CPS/CMS Index Authoring

Static News The Good 1) Simple 2) Scales cheaply 3) Difficult to break [bad rendering logic etc..] 4) Handles high load

Static News The BAD
Relational taxonomic
meta model
2) Static! Inflexible! SSI! 3) Document publishing 4) Content non re-usable 5) Content non repurpose-able 6) Difficult to personalize 7) Publication per output

BBC World Cup 2010 http://bbc.co.uk/worldcup

32 teams, 8 groups, 736 players  776 pages
Fixtures & Results, Groups & Teams pages
To many web pages for too few journalists
Improve the publishing system to help achieve all of this
World Cup 2010

Page Per Player http://news.bbc.co.uk/sport/football/world_cup_2010/groups_and_teams/team/england/wayne_rooney

Page Per Team

Page Per Group

Semantic publishing USER EXPERIENCE ONTOLOGY TRIPLE STORE

Rationale
Automated content publishing
Huge increase in content breadth (number of manageable pages)
Content re-use and re-purposing, increasing reach
Simplified content management
Journalist headcount reduction
Multi-dimensional entry points and semantic navigation
Improved user experience with high levels of user engagement
Dynamic, state (time|event) and semantic driven page layout
Personalized content
Open data and API’s

Dynamic Semantic Architecture [DSP]

API Stack

Highly Scalable Clustered BigOWLIM
Horizontally scalable
No single point of failure
Fault tolerant

Plenty of Caching

Extendable Domain Driven Asset Tagging

Open Ontology/Dataset reuse Event | Geonames | Foaf | Etc.

World cup ontology

Graffiti: Suggest -> Tag [Player]

Graffiti: Suggest -> Tag [Location] (Geonames)

Tag player Infer team Infer competition  Happy Journalist

World Cup statistics
750+ Dynamic aggregations/pages (Player, Squad, Group, etc..)
Average unique page requests a day : 2 million +
Average BigOWLIM SPARQL queries a day : 1 million
100s RDF statement updates/inserts per minute with full OWL reasoning and associated inference. Including sports statistics
Multi data center fully resilient, clustered 6 node triple store
