Complexity of temporal query abduction in DL-Lite

Author: Klarman, S ; Meyer, T Date: Jul 2014 Temporal query abduction is the problem of hypothesizing a minimal set of temporal data which, given some fixed background knowledge, warrants the entailment of the query. This problem formally underlies a variety of forms of explanatory and ... Read more
Description logics of context

Author: Klarman, S ; Gutierrez-Basulto, V Date: May 2013 We introduce Description Logics of Context (DLCs) - an extension of Description Logics (DLs) for context-based reasoning. Our approach descends from J. McCarthy's tradition of treating contexts as formal objects over which one can quantify ... Read more
Ontology learning from interpretations in lightweight description logics

Author: Klarman, S ; Britz, K Date: Aug 2015 Data-driven elicitation of ontologies from structured data is a well-recognized knowledge acquisition bottleneck. The development of efficient techniques for (semi-)automating this task is therefore practically vital - yet, hindered by the ... Read more
Practical querying of temporal data via OWL 2 QL and SQL: 2011

Author: Klarman, S Date: Dec 2013 We develop a practical approach to querying temporal data stored in temporal SQL:2011 databases through the semantic layer of OWL 2 QL ontologies. An interval-based temporal query language (TQL), which we propose for this task, is defined via ... Read more
Prediction and explanation over DL-Lite data streams

Author: Klarman, S ; Meyer, T Date: Dec 2013 Stream reasoning is an emerging research area focusing on the development of reasoning techniques applicable to streams of rapidly changing, semantically enhanced data. In this paper, we consider data represented in Description Logics from ... Read more
Querying temporal databases via OWL 2 QL

Author: Klarman, S ; Meyer, T Date: Jun 2014 SQL:2011, the most recently adopted version of the SQL query language, has unprecedentedly standardized the representation of temporal data in relational databases. Following the successful paradigm of ontology-based data access, we develop ... Read more
TBox abduction in ALC using a DL tableau

Author: Halland, K ; Britz, K ; Klarman, S Date: Jul 2014 The formal definition of abduction asks what needs to be added to a knowledge base to enable an observation to be entailed. TBox abduction in description logics (DLs) asks what TBox axioms need to be added to a DL knowledge base to allow ... Read more
Towards unsupervised ontology learning from data

Author: Klarman, S ; Britz, K Date: Jul 2015 Data-driven elicitation of ontologies from structured data is a well-recognized knowledge acquisition bottleneck. The development of efficient techniques for (semi-)automating this task is therefore practically vital — yet, hindered by the ... Read more
