The University of Oslo is closed. The PhD defence and trial lecture will therefore be fully digital and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the audience to ask ex auditorio questions either written or oral. This can be requested by clicking 'Participants -> Raise hand'.
Trial lecture
"Combining symbolic and non-symbolic knowledge representation for explainable AI solutions”
Main research findings
Many modern search systems allow users to narrow down their search by applying one or more search filters to the available data. This works well until the combination of filters becomes too restrictive, and no results remain. When this happens, the user needs to backtrack and remove the filter they just added, which is very counterproductive. In order to prevent this from happening, the search system should detect and disable too restrictive filters before the user activates any of them.
Current solutions are only able to do this in some special situations, but the solution presented in this thesis is more flexible and works in any situation.
