      Ontology Based Data Access (OBDA) is a prominent approach to query databases which uses an ontology to expose data in a conceptually clear manner by abstracting away from the technical schema-level details of the underlying ...
    • Ontology change management and identification of change patterns 

      Javed M; Abgaz YM; Pahl C (Springer, 2012)
      Ontologies can support a variety of purposes, ranging from capturing the conceptual knowledge to the organisation of digital content and information. However, information systems are always subject to change and ontology ...
    • Ontology evolution for learning content management systems 

      Pahl C; Javed M; Abgaz YM (AACE, 2013)
      Learning content management systems have become common tools to support the development and delivery of digital learning content for many years. We investigate here how semantic annotation can support the management of ...
    • An ontology for software component matching 

      Pahl C (Springer Verlag, 2007)
      Matching is a central activity in the discovery and assembly of reusable software components. We investigate how ontology technologies can be utilised to support software component development. We use description logics, ...
    • Ontology merging as social choice: Judgment aggregation under the open world assumption 

      Porello D; Endriss U (Oxford University Press, 2014)
      The problem of merging several ontologies has important applications in the Semantic Web, medical ontology engineering and other domains where information from several distinct sources needs to be integrated in a coherent ...
    • Ontology support for web service processes 

      Pahl C; Casey M (ACM, 2003)
      Web Services are software services that can be advertised by providers and deployed by customers using Web technologies. This concept is currently carried further to address Web service choreography. Choreography refers ...
    • Ontology-Based Access To Temporal Data With Ontop: A Framework Proposal 

      Güzel Kalayci E; Brandt S; Calvanese D; Ryzhikov V; Xiao G; Zakharyaschev M (2019)
      Predictive analysis gradually gains importance in industry. For instance, service engineers at Siemens diagnostic centres unveil hidden knowledge in huge amounts of historical sensor data and use this knowledge to improve ...
    • An ontology-based approach for modelling architectural styles 

      Pahl C; Giesecke S; Hasselbring W (Springer-Verlag, 2007)
      The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as ...
    • An Ontology-based Architecture for an Adaptable Cloud Storage Broker 

      Elango DM; Fowley F; Pahl C (Springer, 2018)
      Interoperability and easier migration between offered serviced are aims that can be supported by cloud service brokerage in the cloud service ecosytem. We present here a multi-cloud storage broker, implemented as an API. ...
    • Ontology-based composition and matching for dynamic cloud service coordination 

      Pahl C; Gacitua-Decar V; Wang M; Bandara KY (Inderscience, 2012)
      Recent cross-organisational software service offerings, such as cloud computing, create higher integration needs. In particular, services are combined through brokers and mediators, solutions to allow individual services ...
    • Ontology-based composition and matching for dynamic service coordination 

      Pahl C; Gacitua-Decar V; Wang M; Bandara KY (Springer, 2011)
      Service engineering needs to address integration problems allowing services to collaborate and coordinate. The need to address dynamic automated changes - caused by on-demand environments and changing requirements - can ...
    • Ontology-based composition and transformation for model-driven service architecture 

      Pahl C (Springer, 2006)
      Building service-based architectures has become a major area of interest since the advent ofWeb services. Modelling these architectures is a central activity. Model-driven architecture is a recent approach to developing ...

      Calvanese D; Kalaici TE; Montali M; Tinella S (Springer, 2017)
      Process mining aims at discovering, monitoring, and improving business processes by extracting knowledge from event logs. In this respect, process mining can be applied only if there are proper event logs that are compatible ...
    • Ontology-Based Data Access with a Horn Fragment of Metric Temporal Logic 

      Brandt S; Güzel Kalaycı E; Kontchakov R; Ryzhikov V; Xiao G; Zakharyaschev M (AAAI Press, 2017)
      We advocate datalogMTL, a datalog extension of a Horn fragment of the metric temporal logic MTL, as a language for ontology-based access to temporal log data. We show that datalogMTL is EXPSPACE-complete even with punctual ...
