This work focuses on two aspects: the integration of a set of digital libraries, repositories
and other data providers through the OAI-PMH protocol (Open Archives
Initiative Protocol for Metadata Harvesting) and contextualized documents retrieval in
this integrated repository. It is proposed the use of ontologies and content analysis of
articles in wiki environments in the context definition.
The interest in ontologies is in its use as artifacts of specification domain. An ontology is
a data model that represents a set of concepts and their relationships within a domain of
knowledge.
A wiki is a collaborative environment, containing a collection of items connected by
hyperlinks, which can be edited collectively by using a web browser. In this work, the
wiki environments are used as an auxiliary repository of knowledge to the extraction of
relevant terms. Thus, several concepts and relationships that may not be present in the
ontology that specifies the domain of knowledge (since the construction of ontologies is
a complex process) can be identified.
The result of the developed tool processing is a ranking of documents ordered by a higher
degree of importance with respect to the query provided by a user and a particular domain
of knowledge, which is specified by an ontology.
