Prof. Franz Baader gave a talk about “Ontology-based Monitoring of Dynamic Systems”

05 November 2014, 15:00 – 16:00

Speaker: Franz Baader

Abstract:  Our understanding of the notion “dynamic system” is a rather broad one: such a system has states, which can change over time. Ontologies are used to describe the states of the system, possibly in an incomplete way. Monitoring is then concerned with deciding whether some run of the system or all of its runs satisfy a certain property, which can be expressed by a formula of an appropriate temporal logic.  We consider different instances of this broad framework, which can roughly be classified into two cases. In one instance, the system is assumed to be a black box, whose inner working is not known, but whose states can be (partially) observed during a run of the system. In the second instance, one has (partial) knowledge about the inner working of the system, which provides information on which runs of the syste are possible. In this talk, we will review some of our recent research that investigates different instances of this general framework of ontology-based monitoring of dynamic systems.

Bio: Franz Baader is full professor for Theoretical Computer Science at TU Dresden, Germany, since 2002. He has obtained his PhD in Computer Science at the University of Erlangen, Germany, in 1989. He was senior researcher at the German Research Institute for Artificial Intelligence (DFKI) for four years, and associate professor at RWTH Aachen for eight years.  His main research area is Logic in Computer Science, in particular knowledge representation (description logics, modal logics, nonmonotonic logics) and automated deduction (term rewriting, unification theory, combination of decision procedures). Franz Baader is an ECCAI Fellow since 2004 and a member of the Academia Europea since 2011.

Dr. Artemis Parvizi gave a talk in iSOCO

Dr. Artemis Parvizi, the secondee from University of Aberdeen to iSOCO, gave a talk to her colleagues in Madrid. The detail info is as follows.

Title: A dialogue-oriented ontology authoring interface

Abstract: This project aims to build an ontology authoring interface in which the user is engaged in a dialogue with the system in controlled natural language. We try to understand and analyse the intentions and goals of the users through the use of Competency Questions. The hypothesis is that by adding CQs, the interface not only will be able to have a more intelligent interaction with the user, but also occasionally direct the user.

Dr. Marco Monti gave a presentation at “15th Biennial SMDM European Meeting 2014”

Dr. Marco Monti, one K-Drive researcher from IBM Italian, gave a presentation at 15th Biennial SMDM European Meeting 2014 (http://www.smdm2014.com/). The meeting was held in Elzenveld Hotel and Congress Centre Antwerp, Belgium from June 8 to 10, and had a special focus on clinical decision making in the era of personalized medicine. The title of the presentation is “Advanced content analytics to investigate clinical deviations in cancer treatments“. The work is a collaboration with other researchers of Esther Goldbraich, Zeev Waks, Ariel Farkash, Michele Torresani, Paolo Giovanni Casali, and Boaz Carmeli.

Semantic Web: How far is it from the main stream market?

Dr. Jeff Z. Pan, seconded to iSOCO from last month, is going to give a talk in iSOCO. The title and abstract are as follows.

Title: Semantic Web: How far is it from the main stream market?

Abstract:
Research in Semantic Web Technologies has been going on for more than a decade. People want to know if semantic applications are still only piloted and/or put into production by early adopters, or starting to infiltrate mainstream. As Semantic Web Technologies often deliver backend solutions, not necessarily visible from the outside, it is not always easy to recognise their industrial uptake. In this talk, I am going to share my thoughts on this topic, purely based on public information avaiable out there, as well as on  development within the K-Drive project that might help further industrial uptake.

 

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.
