PERICLES – Space Science Portal

This poster presents the developments carried out by the PERICLES project partner Space Applications Services to augment the operational workflow at B.USOC. This enhances its preservation capabilities and ensures that the experiment outputs, and their metadata, can be easily accessed and exploited by an as wide as possible scientific community. At the same time it […]

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 […]

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 […]
