An ontology supporting planning, analysis, and simulation of evolving Digital Ecosystems
Digital Ecosystems (DEs) are interwoven networks of Digital Objects (DOs), policies, processes, services and user communities, within constantly changing and interacting environments. Their complex grown structures can be difficult to maintain and it can be hard to foresee the impact of planned and unplanned change. The PERICLES EU FP7 project developed the Digital Ecosystem Model […]
Monitoring Term Drift Based on Semantic Consistency in an Evolving Vector Field
The paper presents key outcomes of the PERICLES project in the area of semantic drift and, more specifically, proposes a novel methodology for monitoring semantic drifts and for evaluating the semantic consistency of clusters of terms.
Digital Preservation Based on Contextualized Dependencies
This paper proposes a method that considers the preservation of a number of interdependent digital entities, including documents, in conformance with context related information. A change that influences one of these objects can be propagated to the rest of the objects via analysis of their represented dependencies.
On the Preservation of Evolving Digital Content – The Continuum Approach and Relevant Metadata Models
This paper describes a model-driven approach, termed the Continuum approach, in which models rather than the digital objects themselves can be analysed. In such setting, the use of appropriate metadata is very important, we therefore outline the PERICLES Linked Resource Model, an upper ontology for Modelling Digital ecosystems, and compare and contrast it to the […]
User-Driven Ontology Population from Linked Data Sources
Populating ontologies manually is a time-consuming and error-prone task and, thus, research has shifted its attention to automatic ontology population methodologies. The paper presents PROPheT, a novel ontology population tool for retrieving instances from Linked Data sources and subsequently inserting them into an OWL ontology. The tool offers entirely novel ontology population functionality to a […]
The PERICLES Process Compiler: Linking BPMN Processes into Complex Workflows for Model-Driven Preservation in Evolving Ecosystems
Understanding and reusing archived digital information after a decade of technological advancements, constant developments and changes to software and hardware is a very complex and time consuming task. Without a clear documentation and records of changes, research on the creation and modification of information systems and its associated data is almost impossible. To ease these […]
