Abstract—Presentations are crucial components of the
knowledge sharing in organizations with the purpose of
facilitating organizational acquisition and invention. Current
web applications enabling users to collaboratively create
presentation-like web contents and locate the created contents on
a web page for knowledge sharing are insufficiently supportive of
types of materials for presentations and the functions for visitors.
We addressed challenges such as collaborative creation of web
contents based on existing presentations and sharing created web
contents seamlessly with useful functions and communication
tools. To solve the problems, we proposed SlideStack as a web
platform for organizing and sharing of knowledge using
presentations. The result of an experiment for evaluating a
performance of real-time collaboration features showed that the
especial features of the SlideStack system for improving the
presentation-like web contents ran without problems in practical
use.
