摘要：In this article we discuss usability of a Web-based knowledge portal that was developed to support
knowledge management activities of an educational research organization. The original portal
system initially experienced high levels of user participation. However, this trend has been
recently reversed with flagging log-in access rates. Consequently, a criterion-based usability survey
instrument was designed and implemented online to gather users¡¯ responses and comments.
The survey outcomes indicated that a large number of respondents used the portal sporadically,
with a significant number being completely unaware of many of its services. Based on this feedback,
the existing portal was revamped to ensure more user-centric design that focused on the
cornerstone aspects of user control, ease of navigation, personalization services, and classification
of project listings.
