Ontology development in EEG/ERP Portal

Substantial difficulties related to collecting data/metadata from EEG/ERP experiments are presented. Because of suitable ontology describing EEG/ERP experiments does not exist authors present a custom ontology that is proposed to be discussed within the scientific community. The presented ontology is practically implemented within the EEG/ERP Portal. The EEG/ERP Portal simultaneously serves to interested community as a tool for sharing and managing of custom EEG/ERP experiments. Because of domain ontologies are expressed by the Semantic Web languages (OWL) authors´ present briefly introduction into the Semantic Web technologies. Because of the Semantic Web languages expressivity is different in contrast with the object-oriented code, that is the most often used in current software development, authors´ present the developed Semantic Framework. This framework ensures adding a missing semantic into the input object-oriented code and its transformation into appropriate OWL constructs. Integration of the Semantic Framework into the EEG/ERP Portal ensures an online serialization of stored experiments into an OWL document. A registration of the developed ontology in NIF validates authors´ approach. The NIF registration also enables easy sharing of stored experiments.
