A pragmatic approach to significant environment information collection to support object reuse

This paper introduces the concept of Significant Environment Information (SEI), which takes into account the dependencies of the digital object on external information for specific purposes and significance weights. This information supports object use and reuse, e.g. for a better long-term preservation of data. The paper also introduces the PERICLES Extraction Tool (PET), an open […]

An Ontology Design Pattern for Digital Video

The paper proposes an Ontology Design Pattern (ODP) for modelling digital video resources, which was developed in the context of the PERICLES domain ontologies for Art & Media. The ODP can be found at this address:

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.

Ontology-based Representation of Context of Use in Digital Preservation

The paper proposes a novel, ontology-based representation for modelling context and use-context of digital resources in the digital preservation field. At the core of the proposed representation lies the Linked Resource Model (LRM), an upper ontology for modelling dependencies between digital objects.

Studying the Cohesion Evolution of Genes Related to Chronic Lymphocytic Leukemia Using Semantic Similarity in Gene Ontology and Self-Organizing Maps

This paper offers an interesting overview on the application of some of PERICLES results in the biomedicine domain. In particular, this publication deploys an ontology-based semantic similarity combined with self-organizing maps for studying the temporal evolution of cohesion among Chronic Lymphocytic Leukemia (CLL) -related genes and the extracted information. More information on the open-source tool […]

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.

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 […]
