    • Analyzing impacts of change operations in evolving ontologies 

      Abgaz YM; Javed M; Pahl C (CEUR, 2012)
      Ontologies evolve over time to adapt to the dynamically changing knowledge in a domain. The evolution includes addition of new entities and modification or deletion of obsolete entities. These changes could have impacts ...
    • Composite ontology change operators and their customizable evolution strategies 

      Javed M; Abgaz YM; Pahl C (CEUR, 2012)
      Change operators are the building blocks of ontology evolution. Elementary, composite and complex change operators have been suggested. While lower-level change operators are useful in terms of finegranular representation ...
    • Dependency analysis in ontology-driven content-based systems 

      Abgaz YM; Javed M; Pahl C (Springer, 2012)
      Ontology-driven content-based systems are content-based systems (ODCBS) that are built to provide a better access to information by semantically annotating the content using ontologies. Such systems contain ontology layer, ...
    • A framework for change impact analysis of ontology-driven content-based systems 

      Abgaz YM; Javed M; Pahl C (Springer, 2011)
      The trend in content-based systems (CBSs) is shifting towards the use of ontologies to semantically enrich the content and increase its accessibility. The growing need of semantically rich content becomes a driving force ...
    • Graph-based discovery of ontology change patterns 

      Javed M; Abgaz YM; Pahl C (CEUR, 2011)
      Ontologies can support a variety of purposes, ranging from capturing conceptual knowledge to the organisation of digital content and information. However, information systems are always subject to change and ontology change ...
    • Layered change log model: bridging between ontology change representation and pattern mining 

      Javed M; Abgaz YM; Pahl C (Inderscience, 2014)
      To date, no ontology change management system exists that records the ontology changes based on the different levels of granularity. Once changes are performed using elementary level change operations, they are recorded ...
    • A layered framework for pattern-based ontology evolution 

      Javed M; Abgaz YM; Pahl C ([s.n.], 2011)
      The challenge of ontology-driven modelling of information components is well known in both academia and industry. In this paper, we present a novel approach to deal with customisation and abstraction of ontology-based model ...
    • 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 ...
    • Ontology-based domain modelling for consistent content change management 

      Javed M; Abgaz YM; Pahl C (waset.org, 2010)
      Ontology-based modelling of multi-formatted software application content is a challenging area in content management. When the number of software content unit is huge and in continuous process of change, content change ...
    • A Pattern-based framework of change operators for ontology evolution 

      Javed M; Abgaz YM; Pahl C (Springer, 2009)
      Change operators are the building blocks of ontology evolution. Different layers of change operators have been suggested. In this paper, we present a novel approach to deal with ontology evolution, in particular, change ...
    • Utilising ontology-based modelling for learning content management 

      Pahl C; Javed M; Abgaz YM (AACE, 2010)
      Learning content management needs to support a variety of open, multi-format Web-based software applications. We propose multidimensional, model-based semantic annotation as a way to support the management of access to and ...
