Communications from the Particle Frontier
MultiMedia and Visualisation Innovations for Science Workshop
Tim Smith – CERN/IT Department
Tim Smith @ ICSTI Workshop, Feb 2011 <2>
Contents
• MultiMedia in Science Communications
• MultiMedia in Science Practice– A random walk through our digital library “lab”– Supporting technology
Tim Smith @ ICSTI Workshop, Feb 2011 <3>
Multi-Media to engage
• Colliderscope
• Sonification
• CERNLand
Tim Smith @ ICSTI Workshop, Feb 2011 <4>
• Cathedrals of Science !– 100m underground, 46mx25m, inaccessible 95% of year
• ATLAS mural
• Virtual Tour– Interactive Video– Flash navigation graph
• Cross-points: 360o pan photography• Connectors: 70 videos
Multi-Media for exploration
Tim Smith @ ICSTI Workshop, Feb 2011 <5>
MultiMedia to explain
• Illustration by video– Experimental apparatus– Accelerator operations– Processes under study
Tim Smith @ ICSTI Workshop, Feb 2011 <6>
MultiMedia to explain
• Accurate representation visualization/understanding– 100M channels of readout– Event Displays – Java, XML, converter in C++– Convert, smooth, texture, visualize – video replay
Tim Smith @ ICSTI Workshop, Feb 2011 <7>
Multi-Media to glimpse Theories
• Hidden dimensions• Parallel Universes• Antimatter• Strings
Tim Smith @ ICSTI Workshop, Feb 2011 <8>
Web-broadcast
• Mini-black holes– Earth eating ?
• Public attention– 1M watched LHC launch live
• VC&Fibre network from 5 points– Accompanied by MultiMedia
• Free access to everything• Hence digital library with everything in it

MultiMedia: streaming webcast
• Daily: from locations across site• Dual stream
Tim Smith @ ICSTI Workshop, Feb 2011 <11>
MultiMedia: OnDemand WebLectures
• Synchronized audio/video and slides– Auto slide analysis and chapter creation
• MICALA
Tim Smith @ ICSTI Workshop, Feb 2011 <12>
Enhanced Publications
• Supporting data– Meta data, research data, supplementary plots and
tables, photos of apparatus• Post publication data
– Comments, rankings, reviews• Extensions: Presentations, videos
• Contributed– Or
• Mined
Tim Smith @ ICSTI Workshop, Feb 2011 <13>
Plot Extraction
• Caption extraction… and search
Tim Smith @ ICSTI Workshop, Feb 2011 <14>
Image Similarity Search
• GIFT (GNU Image Finding Tools) and Invenio– Based on visual properties (colour distributions, shapes,
textures, just like key words for text retrieval)
Tim Smith @ ICSTI Workshop, Feb 2011 <15>
Visualizing Patterns of Connection
Tim Smith @ ICSTI Workshop, Feb 2011 <16>
Keyword Visualization
• Auto-Keywording: Particle Physics Taxonomy
Tim Smith @ ICSTI Workshop, Feb 2011 <17>
Back-end Machinery
• Parallelization and dispatching of intensive tasks• Data Mining on the GRID in the Cloud
– OCR processing• Ocropus (open source)• De-skewing, text recognition, hOCR production (html), PDF
– Fulltext indexing• Solr/Lucene, Hadoop, Process Execution Engine• Extension to semantic indexing with HEP ontology
– Bibliometrics• Scientific impact e.g. H-Index
– Author disambiguation• Using affiliations, coauthors, research topics, etc• G. Chen: 963 docs, 21 real authors, only 22 docs not assigned,
97.2% success rate
Tim Smith @ ICSTI Workshop, Feb 2011 <18>
3D Modeling for Visualization
• LHC assembly– Virtual reality (from CAD)
• CMS assembly– 3D modeling - animation
Tim Smith @ ICSTI Workshop, Feb 2011 <19>
GRID Real Time Monitor
• Data transfers• Job activity
