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

Plot Extraction
• Caption extraction… and search
Tim Smith @ ICSTI Workshop, Feb 2011
<13>
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)

Visualizing Patterns of Connection
Tim Smith @ ICSTI Workshop, Feb 2011
<15>
Keyword Visualization
• Auto-Keywording: Particle Physics Taxonomy
Tim Smith @ ICSTI Workshop, Feb 2011
<16>
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
