Abstract Information systems have to deal with an increasing amount of data that is
heterogeneous, unstructured, or incomplete. In order to align and complete data, systems …

An ontology typically provides a vocabulary describing a domain of interest and a
specification of the meaning of terms in that vocabulary. Depending on the precision of this …

This paper provides a survey to and a comparison of state-of-the-art Semantic Web
reasoners that succeed in classifying large ontologies expressed in the tractable OWL 2 EL …

This chapter accompanies the foundational lecture on Description Logics (DLs) at the 7th
Reasoning Web Summer School in Galway, Ireland, 2011. It introduces basic notions and …

Recent years have seen an increasing interest in ontology-mediated query answering, in
which the semantic knowledge provided by an ontology is exploited when querying data …

Informatics in materials science and engineering is playing more and more important role in
contemporary society. Intelligent applications such as new materials discovery, materials …

Reusing ontologies for new purposes, or adapting them to new use-cases, is frequently
difficult. In our experiences, we have found this to be the case for several reasons:(i) differing …

By design, large language models (LLMs) are static general-purpose models, expensive to
retrain or update frequently. As they are increasingly adopted for knowledge-intensive tasks …

We develop a formal framework for comparing different versions of ontologies, and apply it
to ontologies formulated in terms of DL-Lite, a family of 'lightweight'description logics …

This paper describes a new, auto-adaptive algorithm for dead reckoning in DIS. In general
dead-reckoning algorithms use a fixed threshold to control the extrapolation errors. Since a …
