  • Logic and Computation: 100%

Research Areas

  • Knowledge Representation, Description Logics, Computational Logic, Logic, Complexity
Maria Magdalena Ortiz de la Fuente

About

My research is in the field of Knowledge Representation and Reasoning with particular emphasis in Description Logics (DLs). I am interested in the use of Description Logics in data access and data management. One of the central topics of my research is studying combinations of database-inspired query languages and DLs, with emphasis on identifying combinations with favourable computational properties.
