Video PowerSearcher:

A Text-Based Indexing E-Learning System


In our rapidly changing world, information and communication technologies have been influential in the development of education.

Both teaching and learning can benefit from new ITbased
applications that save time and cost and provide practical
solutions for teachers and students.

This article introduces a prototype for a video search system called Video PowerSearcher.

The system provides the capabilities of searching
inside video lectures using text-based search queries.

Video PowerSearcher separates audio from video contents and performs preprocessing activities to identify indexing features for the video which can be utilized at a later stage for search operations.

Experiments were conducted on various lecture videos using Video
PowerSearcher to demonstrate desirable features for

e-learning systems such as simplicity, speed, and accuracy.
