A Web Services Driven Framework for Automatic Learning Object Annotation

ALOA Framework

ALOA is a Web Services driven framework for IEEE LOM compliant automatic learning object metadata generation. ALOA can be used in 2 different ways:

  • ALOA provides a public API as Web Service that can be used by third party applications.
  • ALOA has an extensible architecture. It´s possible to extend the ALOA framework with new components as Extractor or Generator.
  1. An extractor is responsible for extracting text information from a learning object along with more properties about the learning object. Only one extractor can be defined for each learning object type e.g. html, pdf, ppt, word.
  2. A generator is responsible for the actual metatada generation. It uses the output of an extractor and applies data mining techniques to generate one or parts of the metadata.

You can also create your own extractor or generator. To add the same to the ALOA framework, please contact Niels Drobek for more information.
