Ved Intervensjonssentert (IVS), Oslo Universitetssykehus (OUS) jobber vi med å utvikle ny teknologi for helsesektoren, og tester ulike nye metoder. For tiden jobber Inger, doktorgradsstudent ved IVS, med et prosjekt som kombinerer optiske sporingssystem med utvidet virkelighet for å visualisere skjelettet til pasienter for ortopediske undersøkelser. Visualiseringen av skjelettet legges på og registreres til pasienten, slik at det beveger seg sammen med pasienten under undersøkelsen. Det vil gi kirurgen en form for «røntgensyn» som gjør diagnostiseringen enklere (se figuren nedenfor). For visualiseringen bruker vi en Microsoft’s HoloLens. Prosjektet er blitt beskrevet i denne artikkelen: Mixed reality as a novel tool for diagnostic and surgical navigation in orthopaedics - PubMed (nih.gov).

The challenge to be addressed is that many for many relationships between items in databases, there is a simple and a complicated story.  For instance the simple story might be “Town A lies in country B.”  The complicated story is “Town A lies in country B since 1990, according to the government of B, but only since 1995 according to the United Nations.”  In a database containing the full information, queries will usually have to deal with the full details too.

The goal of this thesis is to extend and refine an existing visual user interface for query formulation in such a way that a) databases containing the full information can be queried, b) queries corresponding to the “simple story” can be constructed easily, without bothering users about the details, c) queries involving the details can be posed with a few clicks more.

The master thesis will be carried out as a part of a recent EU project, called Optique (Scalable End-user Access to Big Data), and will give you opportunity to interact with top researchers all over the Europe.

In this thesis, you are expected to implement a method using the log of past queries for ranking and suggesting query extensions as a user formulates a query in OptiqueVQS -- a visual query formulation tool.
