A Web Services Driven Framework for Automatic Learning Object Annotation
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.
- 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.
- 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.
