Semantic web in EEG/ERP portal: Ontology development and NIF registration

A short introduction to the EEG/ERP domain and a software solution for storing and managing of EEG/ERP experiments is presented in this paper. This solution was developed as a standalone web based system available for the community of researches to enable storing of experiments. Because authors´ plan, to register this EEG/ERP portal as a recognizable data source, requires providing a domain ontology authors investigate the transformation of stored experiments into the Semantic web form. The transformation of experiments from the EEG/ERP portal into the Semantic web structures that resulted in the presented ontology is presented. Because the EEG/ERP portal is implemented using common programming technologies (object-oriented code, relational database) based on a different approach then the Semantic web technologies, semantic gaps have to be solved. Authors´ presented a custom framework that adds missing semantics into the object-oriented code using Java Annotations. The set of designed annotations and its usage is presented. The paper also presents the ontology generated using a developed framework. Subsequently the paper simply describes a registration of the domain ontology within the Neuroscience Informational Framework. The result of this paper is the description of way to sharing a domain experiments using the semantic web technologies.
