Experience

UOIT Logo Research Assistant

Data Science Lab - UOIT

Duration:
1y
9m


Research and development on big data under Jaroslaw Szlichta.

  • Invented and developed an object oriented database technology called Ontology Functional Dependencies (OFDs).
  • With OFDs, data can posses relations like inheritance, generalizations, components, multilingual representations, and synonyms.
  • Created a set of algorithms to handle these new constraints for automatically cleaning databases achieving an average accuracy of 85%.
  • Utilized high performance computing techniques to improve cleaning speed by an order of magnitude over traditional methods.
  • Programmed a set of Go libraries to demonstrate the research, with plans to port it to a PostgreSQL plugin.
  • Presented the research at the 2016 Alberto Mendelzon Workshop on Foundations of Data Management (AMW).
  • Published two papers and a thesis on the research (see publications).
