Abstract :
Recording evidence for data values, in addition to the
values themselves, in bibliographic records and descriptive
metadata has been proposed in a previous
study. Recorded evidence indicates why and how data
values are recorded for elements. As a continuation of
that study, this article first proposes a scenario in which
a cataloger and a system interact with each other in
recording evidence in bibliographic records for books,
with the aim of minimizing costs and effort in recording
evidence. Second, it reports on prototype system development
in accordance with the scenario. The system
(1) searches a string, corresponding to the data value
entered by a cataloger or extracted from the Machine
Readable Cataloging (MARC) record, within the scanned
and optical character recognition (OCR)-converted title
page and verso of the title page of an item being cataloged;
(2) identifies the place where the string appears
within the source of information; (3) identifies the procedure
being used to form the value entered or recorded;
and finally (4) displays the place and procedure identified
for the data value as its candidate evidence. Third,
this study reports on an experiment conducted to examine
the system’s performance. The results of the experiment
show the usefulness of the system and the validity
of the proposed scenario.
