The NASA Astrophysics Data System: Architecture

  title={The NASA Astrophysics Data System: Architecture},
  author={Alberto Accomazzi and G{\"u}nther Eichhorn and Michael J. Kurtz and Carolyn S. Grant and Stephen S. Murray},
  journal={Astronomy \& Astrophysics Supplement Series},
The powerful discovery capabilities available in the ADS bibliographic services are possible thanks to the design of a flexible search and retrieval system based on a relational database model. Bibliographic records are stored as a corpus of structured documents containing fielded data and metadata, while discipline-specific knowledge is segregated in a set of files independent of the bibliographic data itself. This ancillary information is used by the database management software to compile… Expand

Worldwide Use and Impact of the NASA Astrophysics Data System Digital Library
The concept of utility time is introduced to measure the impact of the ADS/URANIA and the electronic astronomical library on astronomical research and it is found that in 2002 it amounted to the equivalent of 736 full-time researchers, or $250 million, or the astronomical research done in France.

Approximate personal name-matching through finite-state graphs
Finite-state methods can be employed in a new and different task: the conflation of personal name variants in standard forms, and the usefulness of this approach is demonstrated, although it should be complemented with methods based on similarity relations for the recognition of spelling variants and misspellings.

The Unified Astronomy Thesaurus: Semantic Metadata for Astronomy and Astrophysics
The Unified Astronomy Thesaurus is examined in comparison with the Astronomical Subject Key Words used by major publications and the JWST Science Keywords used by STScI's Astronomer's Proposal Tool. Expand
Properties and nature of Be stars. XXIII. Long-term variations and physical properties of x Dra
We present an analysis of new spectroscopic observations of the bright Be star κ Dra obtained at the Ondy rejov observatory during 1992−2003 and UBV photometric observations secured at severalExpand
Relying on electronic journals: Reading patterns of astronomers
How astronomers use journals and what features and formats they prefer are identified, which may provide a glimpse of what to expect of journal patterns and use by other scientists. Expand
Astronomy Education for the Public via Web Technologies: From the e-Library, through the e-Classroom, towards the e-Facilitator

Three measures were selected which evaluate performance at given rank cutoff points, such as those corresponding to a screenful of document titles, which were used in Croft (1983) as complementary measures to the standard recall/precision evaluation. Expand
Reference Linking in a Hybrid Library Environment
The SFX-framework has further been generalized in order to achieve a technology that can easily be transferred from one digital library environment to another and that minimizes the overhead in making the distributed information services that make up those libraries interoperable with SFX. Expand
