Indexing terminology of documents

As practical information science knows only all too well, due to language change, indexing terminology of documents keeps on undergoing modifications. Consider the following examples for terminology change over time: gramophone - record player; computer screen - monitor; duplicating machine - photocopier; European Coal and Steel Community - Common Market - European Economic Community or EEC - European Community or EC - European...

Presenting advanced access related research in PERICLES at QI-14

The concept of advanced access combines automatic indexing, automatic document categorization, document retrieval and information visualization in digital libraries, and is crucial to any progress in digital preservation (DP). Namely, what would be the point of preserving anything for the future if one had no access to safeguarded content? Lately the temporal aspect of content, its ageing, composition and dynamics, has become a...

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...

How much metadata is too much (and how little is too little)?

How much metadata is too much (and how little is too little)? Practical Preservation and People, December 3rd 2015, Public Records Office of Northern Ireland The DPC metadata event brought together a spirited collection of people from projects and heritage institutions, all interested in seeking an answer to the question posed in the workshop's title: when collecting metadata, how much is too much? It sounds like a dry...

Visualizing data to detect semantic change - Interview with Peter Wittek

In 2015 an open-source tool called Somoclu was developed by Peter Wittek from project partner University of Borås as an enabling key tool in PERICLES WP4 to study semantic drifts on scalable data collections, providing content maps in the hundreds for visual analysis. Semantic drift (also often referred to as “semantic change” or “evolving semantics”) is an active and growing area of research that observes...

SuCCESS’16 - First International Workshop on Semantic Change & Evolving Semantics

The evolution and change of semantics is central to the objectives of the PERICLES project: semantics relates to our shared understanding of the world around us, and in cases where there is a mismatch, then this can lead to a breakdown in our shared understanding and an inability to communicate and exchange information effectively. A couple of well-known examples might be US versus UK English, where in the former you would use the...

From Semantics of Change to Change of Semantics

On 19 May 2015 PERICLES partners ran a half day workshop devoted to the importance of dependency drifts in digital preservation and covered four interlocking research areas: the design of a OWL ontology called LRM (Linked Resource Model) to describe change and dependencies in evolving digital ecosystems on a high level; the application of the LRM to the representation of domain-specific knowledge , and the principle of...

Monitoring Term Drift Based on Semantic Consistency in an Evolving Vector Field - IJCNN 2015

This paper was presented by project partner Stratos Kontopoulos (CERTH) at the International Joint Conference on Neural Networks ( IJCNN'15 ) in Killarney, Ireland (12-17 July 2015). The paper presents key outcomes of the PERICLES FP7 project in the area of semantic drift and, more specifically, proposes a novel methodology for monitoring semantic drifts and for evaluating semantic consistency of clusters of terms.

Studying the Cohesion Evolution of Genes Related to Chronic Lymphocytic Leukemia Using Semantic Similarity in Gene Ontology and Self-Organizing Maps - SWAT4LS 2016

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 co-hesion among Chronic Lymphocytic Leukemia (CLL) -related genes and the extracted information. More information on the open-source tool Somoclu , which has supported...

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.
