This study investigated the longitudinal trends of e-learning research using text mining techniques. Six hundred and eighty-nine (689) refereed journal articles and proceedings were retrieved from the Science Citation Index/Social Science Citation Index database in the period from 2000 to 2008. All e-learning publications were grouped into two…

A program is described which identifies functional group interconversion reactions, hydrogenations, and dehydrogenations in a data base containing structures encoded as Wiswesser Line Notations. Production of the data base is briefly described. (17 references) (Authors)

The logical structure of the data bank is described from the user's point of view, without reference to machine implementation. The length of files, records, segments, and fields are variable and unlimited; duplication factors are unlimited; sequence of files, records within file, and segments within record are random. All data are subject to…

This paper examines some of the finding aids (e.g., information that provides insight into a group of records in an archival collection) currently used or being developed by the National Archives and Records Administration (NARA). It explores their practicality and whether and how they can be improved. In addition, the paper analyzes the factors…

With the growth of computer technology, bibliographic data bases have developed into sophisticated online research tools. The major data bases are produced by abstracting and indexing (A&I) publishers. Vendors purchase the A&I publishers' machine readable tapes, then sell computer access to the tapes to information based organizations such…
