NSR – June 2005 to May 2007


Keyword preparation in vienna

Late in 2005, Vienna took responsibility for preparing keywords for selected European journals: Nucl.Phys.A, Eur.Phys.J.A, and Phys.Lett.B.

Eventually, this will be about 20-25% of the keywording effort.

Files are prepared at NNDC and sent to Vienna for keywording.

Keyword preparation in Vienna


Changes to subject indexing

NSR “selector” field is generated from keyword field, used to create indexed searches on nuclide, subject, etc.

New “prep” program written to generate selectors.

Selectors for all entries re-generated, made publicly available on web in May 2007.

Complete exchange-format file with new selectors made available to collaborators.

Changes to subject indexing


Changes to subject indexing continued

Daughter nuclides calculated and indexed in “Radioactivity” keywords, where possible.

New selector tags: “P” for parent, “G” for daughter.

Specific subjects generated by reaction strings (i.e., “CHARGEX”, “POLARIZED”...)

Multiple selectors generated for some keyword phrases.

Minor topics no longer indexed.

“MASS” selector generated for “Atomic Masses” articles.

New selectors added (“HALO”, “HYPERFINE” ...).

Changes to subject indexing (continued)


Other database web changes

Authors now indexed by two initials, rather than one. Required rebuilding of author and alias dictionaries.

If author is entered as a search parameter, and more than one author/alias matches, then a list of matching names will be given at the bottom of the search results.

Searching on “Nuclide” will look for entries with “N”, “P”, and “G” selectors.

“List analyze” feature added to web site.

Other database/web changes


Change in database manager

Dr. Winchell has been the database manager for NSR for the last decade, and decided to leave NNDC on May 31st 2007 to pursue his other interests.
