Geometric Models for (Temporally) Attributed Description Logics
Camille Bourgaux, Ana Ozaki, Jeff Z. Pan
In the search for knowledge graph embeddings that could capture ontological knowledge, geometric models of existential rules have been recently introduced. It has been shown that c…
Revising Ontologies via Models: The ALC-formula Case
Jandson S. Ribeiro, Ricardo Guimarães, Ana Ozaki
Most approaches for repairing description logic (DL) ontologies aim at changing the axioms as little as possible while solving inconsistencies, incoherences and other types of unde…
On Free Description Logics with Definite Descriptions
Alessandro Artale, Andrea Mazzullo, Ana Ozaki +1
Definite descriptions are phrases of the form 'the such that ', used to refer to single entities in a context. They are often more meaningful to users than individual names…
Learning Description Logic Ontologies. Five Approaches. Where Do They Stand?
Ana Ozaki
The quest for acquiring a formal representation of the knowledge of a domain of interest has attracted researchers with various backgrounds into a diverse field called ontology lea…
On the Complexity of Learning Description Logic Ontologies
Ana Ozaki
Ontologies are a popular way of representing domain knowledge, in particular, knowledge in domains related to life sciences. (Semi-)automating the process of building an ontology h…
Mining EL Bases with Adaptable Role Depth
Ricardo Guimarães, Ana Ozaki, Cosimo Persia +1
In Formal Concept Analysis, a base for a finite structure is a set of implications that characterizes all valid implications of the structure. This notion can be adapted to the con…
