Inferencing

Inferencing

The ontology used plenty of class restrictions and has been able to make meaningful inferences on the imported VU-Pure data. For instance, fig. \ref{994928} shows imported articles serving as a clue for inferring which journal they belong to. In the earlier versions of the ontology, there were, in fact, more inferences being made due to somewhat more liberal class definitions being in use (fig. \ref{371831}, also see fig. \ref{797019}). As the external data tuned better and better to the ontology with the development of the Python scripts used to prepare them, the bibliographical information imported also became more detailed over time, and general inferences (e.g., "all things that has an author is a document") were replaced by more precise assertions that came with the imported file (e.g., "this_instance has type article"). In future, more experimentation could be made to increase the number of inferences, although well-prepared and pre-aligned files may, once again reduce the need for inferencing for crucial information in future work as well.  And unfortunately, the prototype is not yet advanced enough to use the scientific field or organization (i.e., institution) classes (e.g., it cannot yet say an article belongs to a scientific  field). This (crucial) feature will be either implemented next iterations, or if the time constraints prevent it, after completion of the course as part of the research project.
