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
