Generating Actionable Robot Knowledge Bases by Combining 3D Scene Graphs with Robot Ontologies

Published in IEEE International Conference on Robotics and Automation (ICRA), 2025, 2025

We present a unified scene graph model that standardizes 3D scene formats and integrates them with robot ontologies to support actionable knowledge creation.

How Metacognitive Architectures Remember Their Own Thoughts: A Systematic Review

Published in arXiv preprint, 2025

We systematically review how computational metacognitive architectures represent and process their episodic experiences, revealing key patterns and challenges in the field.

An Ontological Model of User Preferences

Published in RobOntics workshop 2023, 2023

In this work, we thus investigate a formal model of preferences where options are non-atomic entities that are defined by the complex situations they bring about

Prolog as a Querying Language for MongoDB

Published in arXiv preprint arXiv:2110.01284., 2021

We propose a new database querying language called Mongolog which is syntactically a subset of the Prolog language, and we define its operational semantics through translations into MongoDB aggregation pipelines.

Ontology Partitioning Using E-Connections Revisited

Published in In Proc. 31st DL, vol. 2211 of CEUR, 2018

We revisit the technique for partitioning ontologies using E-connections introduced by Cuenca Grau et al. (2006).
