Jhonatan Garcia starts his secondment in IBM Italia

Jhonatan Garcia (ESR)’s secondment to IBM Italia has started from 17th May 2014. He will work on WP5 and WP6. In particular, Jhonatan will investigate the following two topics:

  • Stream Maintenance: The aim is to develop efficient and scalable solutions that would handle large volumes of historical stream data. This data has potential value as key queries are expected to be repeated numerous times. A starting point would be to study how new data affect historical answers from the knowledge base; i.e. what is the minimum amount of changes that would require a recalculation of existing results, and what is the minimum recalculation required for a given update in the knowledge base.
  • Uncertainty handling: The aim is to develop an efficient reasoner that would take into consideration uncertain, probable, or possible data. This reasoner must be able to apply inference over this non-crisp set, and return the most consistent answer possible. It would be helpful to first study successful applications of Subjective Logic in academic research and see if any of these approaches can be used on a stream reasoner.

 

 

Dr. Panos Alexopoulos will give a seminar to CSD of UNIABDN about vagueness

Speaker: Dr. Panos Alexopoulos (iSOCO)

Title: Detecting, Analyzing and Representing Vagueness in Ontologies for Facilitating Reuse.
Info: Tuesday, April 1, 14:00-15:00, MT 203

Abstract: The emergence in the last years of initiatives like the Linked Open Data (LOD) has led to a significant increase of the amount of structured semantic data on the Web. Nevertheless, the wider reuse of such data is inhibited by a variety of factors, ranging from the quality of the data to the richness/explicitness of its ontological descriptions. In this talk, we focus on the phenomenon of vagueness as a potentially problematic factor for the shareability and reusability of ontologies and semantic data, and we describe a novel approach for dealing with it. Key components of this approach include a vague sense classifier that may automatically identify vague ontological elements as well as the Vagueness Ontology, a metaontology for annotating these elements with explicit descriptions of their vagueness.

Boris Motik will give his 2013 Needham lecture here in Aberdeen at on 25th Feb, 2014

Title: Theory and Practice: The Yin and Yang of Intelligent Information Systems
[1] http://academy.bcs.org/events/2013-needham-lecture-dr-boris-motik

Abstract:
Theoretical and practical research complement each other, and their synergy is essential to developing advanced information systems. I will illustrate this using examples from my research in ontology languages, reasoning, and big data management. I will also discuss how we can foster interest in combining theory and practice in undergraduate and postgraduate education.

Short bio:
Dr Boris Motik completed his undergraduate and master’s degrees at the University of Zagreb. After a stint in the software development industry in the USA and Germany, in 2002 he embarked on his PhD studies at the University of Karlsruhe (today known as the Karlsruhe Institute of Technology) under supervision of Prof. Rudi Studer. He completed his studies in 2006 and then started his postdoc in the group of Prof. Ian Horrocks at the University of Manchester. Finally, he was appointed to a university lecturer post at the University of Oxford in 2007.
