E-learning has acquired a prime place in many discussions
recently.
    A number of research efforts around the world are trying to enhance
    education and training using e-learning. This paper briefly explains
    one such attempt aimed at designing a system to support video clips
    in e-learning and explains how profiles of the presenters in video
    clips can be used to improve the usefulness of e-learning systems.
    Then it discusses one of the main problems identified in profile
    construction. Finally, it presents a solution to this problem and
    describes a novel algorithm for improving the efficiency of the profile
    construction process.},
