information science
information science
discipline that deals with the processes of storing and
transferring information. It attempts to bring together concepts
and methods from various disciplines such as library science, computer
science and engineering, linguistics, psychology, and other
technologies in order to develop techniques and devices to aid
in the handling--that is, in the collection, organization,
storage, retrieval, interpretation, and use--of information.
The transfer of information through time requires the
existence of some storage medium, which is designated a
document--hence the term documentation. Historically,
"documentation" emerged as a distinct discipline in
the early 20th century, paralleling the rise of empirical
research, which was to provide its main source of subjects. The
discipline grew in response to the growth of the periodical and
the journal as the prevalent media for scientific reports.
Whereas books required control through cataloging and
classification, periodicals required indexes and abstracts that
would bring together for the researcher primary information
originally published in divergent sources.
The roots of the discipline of information science lay in
three post-World War II developments: the Shannon-Weaver
information theory model, Norbert Wiener's conception of the
science of cybernetics, and rapid advances in the design and
production of electronic computers. These innovations pointed to
a new field of study in which many disciplines could be merged
under the unifying idea of "information." After the
Georgia Institute of Technology established the first formal
information science program in 1963, the discipline quickly
developed at a number of other universities either as an
independent field of study or as a specialty within such
departments as library science, computer science, or
engineering.
In its early stages during the 1960s, information science was
primarily concerned with applying the then-new computer
technology to the processing and managing of documents. Modeling
studies were undertaken of the effectiveness of information
storage and retrieval; modes of human-machine interaction; the
effect of form on the content and comprehension of information;
the processes of information generation, transmission, and
transformation; and the establishment of general principles that
explain and predict information phenomena.
The applied computer technologies--and more recently,
the theoretical areas of study--of information science have
since permeated many other disciplines and have even been
appropriated by new fields, each preferring a more descriptive
designation of its subject domain. The institutionalization of
information science as a discrete discipline thus has not
occurred, and the number of its scientist-practitioners is low. Computer
science and engineering tend to absorb the theory- and
technology-oriented subjects of the field, and management
science tends to absorb the information systems subjects.
Hundreds of professional associations do exist that are
concerned with information-related disciplines, providing a
forum where people can exchange ideas about information
processing.
