ABSTRACT: Objective: Information visualization is the
study of interactive depictions of abstract and data to strengthen the human
cognition. Designing an appropriate information visualization system may be
very useful technique for scholars, who intent to get scientific information
from digital libraries. The objective of current study was to map and visualize
the key-information of dissertations in academic libraries. To achieve the aim,
an information retrieval system was designed to present the interactive graphic
view of dissertations’ subjects in academic. Methods: An information retrieval
system was designed by information visualization toolkit that presents the
related subjects of dissertations in academic libraries. In addition, the
satisfaction-levels of library-users were analyzed by administrating a standard
questionnaire (QUIS Questionnaire). Results: The study indicated that the
designed IR system helped to provide a user-friendly environment through
displaying subjective relations of dissertations, overwhelming variety of
colors in displaying information. Fast and easy access to the cover-to-cover
information of dissertations and user-interaction facilities are the advantages
of designed IR. Analysis of data furthermore indicated that the users’ satisfaction
from the system was from medium to high grade. Conclusion: Designing the
IR-system revealed an excessive influence on users’ satisfaction; therefore,
proposing such systems for employing in academic libraries is very suitable and
its implementation is necessary.
