Monitoring the semantic drift of index terms by an evolving vector field: a novel experimental approach

The evolution of semantics refers to possible shifts in the interpretation of a concept over time and/or contrasts in its interpretation between user communities, due to linguistic, socio-cultural or psychological factors. In literature, the above phenomenon is covered by expressions like “semantic change”, “semantic shift”, “semantic decay”, and sometimes as “concept drift”, all of which are categorized under the...

Linked Resource Model for modelling evolving systems (3rd PERICLES Technical Workshop in Grenoble, France)

Xerox Research Centre Europe (XRCE) organized a third technical workshop on using/extending the Linked Resource Model (LRM). The workshop was hosted by the XRCE in Grenoble, and took place on the 27-29 April 2015 (see blogs for the first two meetings). [1] [2] The LRM is an upper level ontology that is being developed within PERICLES, to enable the description of evolving digital ecosystems. Versions of the LRM that could...

October workshops: Introducing experts to key PERICLES concepts

Last month PERICLES ran two workshops with practitioners and experts in the fields of digital preservation and science data. The full-day events were organised at two different locations, London (15 October) and Brussels (29 October) to introduce specific topics that are key elements within PERICLES research and development. The first workshop entitled 'Model-driven approach to preservation management' was focussed on the...

Exploring appraisal, quality assurance and risk assessment in the data continuum

PERICLES was invited by the IDCC to run a workshop on 25 February 2016 as part of the 11th International Digital Curation Conference (IDCC16, Amsterdam). We prepared a half-day session on appraisal, quality assurance and risk assessment in relation to the lives of complex digital objects. The workshop was designed to introduce participants to some of the key concepts being explored in the PERICLES approach of...

Policy implementation and change management - the PERICLES way

In this blog post we present a practical example of how the PERICLES model-driven approach can help to implement, automate and manage change in a policy. 'Automatic policy application and change management’ was also the focus of one of the 'PERICLES in Practice' sessions at the final project conference ‘Acting on Change: New Approaches and Future Practices in LTDP’ . In this presentation (available on...


The EcoBuilder and Digital Ecosystem Modelling

This is an introduction to the Ecobuilder, a tool for the creation of Digital Ecosystem Models (DEMs) via Java API or via GUI developed by Anna-Grit Eggers with the University of Goettingen (Germany). The DEM is a means to express the network of dependencies, and interactions of entities in digital ecosystems. The tool has been developed within PERICLES, a four-year Integrated Project (2013-2017) funded by the European Union under...


Basic Tools for Digital Ecosystem Management

This deliverable describes the current state of the WP5 Digital Ecosystem (DE) research and tools developed for the PERICLES project, together with the concepts, models and software associated with them. The developed tools can be used independently or in combination with test scenarios, which will be part of the WP6 test beds.

Linked Resource Model

This document describes the Linked Resource Model (LRM), an OWL ontology that can be used to model dependencies between digital resources and enable the description of evolving digital ecosystems.

Modelling Contextualised Semantics

This document summarises the work conducted within task T4.4 of WP4, presenting our proposed models for semantically representing digital content and its respective context – the latter refers to any information coming from the environment of the digital object (DO) that offers better insight into the object’s status, its interrelationships with other content items and information about the object’s context of use.


SOLAR Space Science Portal - PV 2015

This poster was presented by project partner David De Weerdt (Space Applications) at the PV 2015 conference held 3-5 November 2015 in Darmstadt (Germany) and organised by EUMETSAT. This poster presents how space science related data use and reuse complications can be tackled with an integrated graph-oriented modeling approach.

Integrating Preservation into experimental workflows for space science - PV 2015

This presentation was delivered by project partner Simon Waddington (King's College London) during the PV 2015 conference held 3-5 November 2015 in Darmstadt (Germany) and organised by EUMETSAT. The presentation introduced PERICLES approach to long term preservation of data and environmental information generated by the SOLAR experiment, being run on the International Space Station.

Dependency modelling for inconsistency management in Digital Preservation – The PERICLES approach - Springer Journal

An extended version of the PERICLES paper presented at SW4CH 2015 by Nikolaos Lagos from project partner XEROX is now available on the Springer Journal "Information Systems Frontiers" at the link below: This paper presents one of the key outcomes of the PERICLES FP7 project, the Linked Resource Model, for modelling dependencies as a set of evolving linked resources. The adoption of the proposed model...

Taking a long-term perspective - Maintaining digital assets by managing their evolving digital ecosystems

As digital content and its related metadata are generated and used across different phases of the information lifecycle, and in a continually evolving digital environment, the concept of a fixed and stable ‘final’ version that needs to be preserved becomes less appropriate. As well as dealing with technological change and obsolescence, long-term sustainability requires us to address changes in context. Such a changing...
