We are pleased to announce that we will have a two-day K-Drive workshop (25-26th of September, 2014) in Aberdeen. The venue is Meeting Room 3, Sir Duncan Rice Library, University of Aberdeen.
Dr. Honghan Wu demonstrated K-Drive’s query generation work at CSWS2014 (http://csws2014.ontoweb.cn) which was hosted Wuhan, China. The demo system is available at http://homepages.abdn.ac.uk/honghan.wu/pages/kd.wp3/.
K-Drive coordinator, Jeff Z. Pan starts his secondment to iSOCO from 22nd May 2014. In this secondment, Jeff will work on WP4, project managements, and future cooperation plans with iSOCO colleagues.
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.
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.
Dr. Panos Alexopoulos from iSOCO gave a talk about “Reasoning with vagueness” in UNIABDN’s Semantic Web Lunch (1st, April).
Two days of K-Drive workshop starts on 26th March 2014. The work packages to be covered are as follows.
iSOCO and UNIABDN:
D4.3 Intelligent UI prototype (M30, iSOCO)
Discuss on Artemis’ secondment plan;
D7.1 User modeling definition: a PU Specification (M30, UNIABDN)
Discuss on connections with Sam’s topic (business profile match-making);
IBM and UNIABDN:
D5.1 A dynamic knowledge base: a PU specification (M24, IBM)
– Identify current best practices in IBM’s use case;
– Define the evaluation method for the use case;
– Applying results from WP3 (Query Generation / Query Answering) on IBM’s use case
– Comparing the results and identifying the gap;
D5.2 A dynamic query generator: a PU Prototype (M30, UNIABDN)
D6.2 Stream querying for open data: a PU report (M30, UNIABDN)
Discuss on Jhonatan’s secondment plan;
Time: 10:45-17:45, March 25th (Tuesday), 2014

Title: Theory and Practice: The Yin and Yang of Intelligent Information Systems
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.
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.
This talk is sponsored by K-Drive project
On 25th March 2014, we will have an Open Excellent Workshop located in Room 203, Meston Building, University of Aberdeen. The theme will be published very soon. Following this event, we will have a two-day K-Drive workshop on 26-27th March 2014. The venue will be Meeting Room 3, The Sir Duncan Rice Library.
