Electronic publications are often available in XML-formats. However, these are only limitedly machine-readable and self-descriptive. Semantic technologies such as RDF (Resource Description Framework) can, in conjunction with underlying ontologies, which supply vocabulary and structures of meaning, assign a well-defined meaning to text information. This makes the access of information using standardized search languages and protocols such as SPARQL (SPARQL Protocol and RDF Query Language) possible.
The ZPID’s publication platform PsychOpen uses Open Journal Systems (OJS) for journal administration. The semantic enhancement of journal articles encoded in JATS-XML format is achieved using the SE4OJS (Semantic Enhancement for the Open Journal Systems) software, developed within the scope of KOBPSY. Semantic annotation takes place on two levels:
The obtained database can then be queried flexibly. Within the scope of KOBPSY, applications are to be developed, which perform queries and display results for the end user graphically.
A further focus of the project is the evaluation of available ontologies. Currently, hardly any resources exist for the field of psychology. A flat representation of the APA-Thesaurus on Bioportal is publically available as an OWL-ontology. It covers a wide spectrum of domain-specific concepts, however only defines few relations between concepts and was originally developed for the indexation of documents using key words. Another psychology resource developed by the DFKI and ZPID is not publically available to date (see project KOIOS++). Furthermore, there are many biomedical ontologies that may be partially relevant for the field of psychology. Based on the specific applications for KOBPSY, the collection of demands on a general ontology for the field of psychology are to begin.
