Dynamics of Knowledge Organisation

An interdisciplinary approach to time, change, semantics and ordering
English
English [Auto]
Get a first glance at cutting-edge methods and technologies (semantic technologies, vector fields, ontologies).
Relate theories of word meaning to vector-based information representation.
Learn about the foundations of the Semantic Web initiative and its core concepts and technologies.
Explore the relevance of semantic technologies to vastly interdisciplinary fields, like Digital Preservation.
Get a better view of the emerging paradigm of knowledge representation through ontologies.
Discuss how ontology evolution (i.e. the change of ontologies over time) can serve as a means for studying semantic drift.

Requirements

  • Εlementary understanding of text processing
  • Βasic knowledge of the fundamentals of HTML and XML

Description

Together we’ll explore the involvement and application of semantics in Digital Preservation. We will look at the difference between sentence and word meaning as well as how semantic decay endangers access to digital objects over time. We will also explore the shared concerns of philosophy, semantics, semiotics, logic, and information science to model and understand semantic drifts that endanger future access to preserved content. 

This course will familiarize you with core ideas for representing word meaning by vectors, including a respective match between linguistics and information science. Together we will explore open-ended research questions and an ongoing effort to model semantic change on a vector field as well as the emerging paradigm of the Semantic Web and the core underlying technologies. We will also introduce technologies related to Digital Preservation as well as notions of evolving semantics and semantic drift.

The material presented in this course is based on the results of the EU-funded research project PERICLES: Promoting and Enhancing Reuse of Information throughout the Content Lifecycle taking account of Evolving Semantics.

Who this course is for:

  • Digital Preservation and Digital Humanities practitioners who are interested in investigating the deployment of semantics and relevant cutting-edge technologies.
  • Researchers working on semantics who are interested in investigating the application of relevant methods and technologies in a Humanities field.

Received his PhD in Artificial Intelligence from the Aristotle University of Thessaloniki in 2011. He also holds a BSc in Applied Mathematics from the same University (2003) and an MSc (Dist) in Computer Science from the University of Essex, UK (2004). He participated in several national and international research projects and published a number of international journal and conference proceedings papers. He currently works as a Senior Researcher at the Information Technologies Institute (ITI) of the Center for Research and Technology, Hellas (CERTH). His research interests include Knowledge Representation and Reasoning, Semantic Technologies and Rule-based Systems.

Sándor Darányi has research interests in advanced access to digital libraries; digital preservation; narrative genomics for the study of intangible cultural heritage (e.g. mythologies and tales); quantum interaction; and evolving semantics. In the latter area, his recent interest is social mechanics, i.e. the influence of community context on language dynamics. He has been involved in several national and international research projects, with publications on e.g. the integration of simulations in formal models of digital libraries; physics as a metaphor to model language change; and formalization of folk narratives for the extraction of test collections from unstructured big data. With an international background, he has been employed at the University of Borås (Sweden) since 2003.
