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.

The Challenges of Numeric Data:
Data sets are hard to navigate.
The Challenges of Numeric Data:
Data sets are hard to cite.
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.
DataCite Registers DOI
DOE-OSTI submits nightly feed of new
DOIs to DataCite
How Data Citation WorksData Citation
metadata submitted to DOE-OSTI
•Dataset Type •Dataset Title •Dataset Creator/Author or Principal Investigator •Dataset Product Number •DOE Contract/Award Number
•Originating Research Organization •Publication/ Issue Date •Sponsoring Organization •URL where the Dataset is posted for access •Contact information

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.

Summary
Big Data is here.Data citation makes data:
easier to find easier to navigate
Scientific multimedia is here.Speech indexing makes multimedia:
easier to search more productive for the scientist and student
