Nuclear Data
Nuclear Data* Types:
Experimental (e.g., Experimental Nuclear Reaction Data (EXFOR)) Evaluated (e.g., Evaluated Nuclear Data File (ENDF-6) and Evaluated Nuclear
Structure Data File – ENSDF) Reaction: incident neutrons and incident charged particles and photons Structure and decay data: half-lives, decay schemes, etc. (Nuclear Data Sheets)
Other data-intensive nuclear fields: Nuclear medicine Radiation safety Waste management and environmental research Materials analysis Safeguards Nuclear astrophysics

The Challenges of Numeric Data:
Data sets are hard to find.

Why Cite Data?
Data should be cited in just the same way that other sources of information, such as articles and books, are cited.
Data citation can help by:
enabling easy reuse and verification of data allowing the impact of data to be tracked creating a scholarly structure that recognizes and rewards data
producers

One Solution: DataCite
What is DataCite?
A global consortium composed of local institutions focused on improving the scholarly infrastructure around datasets and other non-textual information.
A service for assigning Digital Object Identification (DOIs) and metadata to data sets.

Experiments/Simulations
YouTube search on “nuclear” has 3,090,000 results

The Challenges with Multimedia Science Information
Lack of written transcripts, i.e. no “full text” to search
Metadata, if available, is often minimalScientific, technical, and medical
terminology/vocabularyVideos can be long, often up to an hour or
more

Access to Multimedia-based Science & Technology
A Case Study for Enhanced Multimedia Search & Retrieval
http://www.osti.gov/sciencecinema/
• Partnership between OSTI and Microsoft Research.• Launched in February 2011; searches ~2,600 multimedia
files from DOE and CERN.• Utilizes Microsoft Research Audio Video Indexing System
(MAVIS).• Enables searching of digitized spoken content.• Users can search for precise term within video and be
directed to the exact point in the video where the term was spoken.
