Taking advantage of LOM semantics for supporting lesson authoring

Abstract

Learning Object Metadata (LOM) is an interoperable standard aimed to foster the reuse of learning material for authoring lessons. Nevertheless, few work was done on taking advantage of LOM-semantics to facilitate retrieval of learning material. This article suggests an original approach which uses the structure of a lesson in order to automatically generate LOM-semantic-based queries for retrieving learning material for that lesson whereas the user continues to formulate easy-to-write queries without semantic specifications. This proposal consists of a four-component framework attempting to consider the main issues of semantic-based retrieval of documents
