Computing Science Seminar. Everson on "Visualising and understanding multi-objective solutions and league tables"
-Abstract: Recent advances in evolutionary optimisation algorithms mean that it is possible to find approximations to the optimal trade-off between several objectives. With only two or three objectives visualising the trade-off and relations between solutions is straightforward, but with more objectives understanding the solutions and available trade-offs is difficult. This talk will briefly...

Computing Science Seminar. Elsenbroich on "Modelling Extortion Rackets"
-Abstract: Extortion is a different kind of crime to other property crime such as burglary, robbery or even fraud. What makes extortion unique is a) the long-term relationship of the criminal with the victim and b) the reliance on the threat of future punishment rather than actual punishment. The two...

Computing Science Seminar. Alexopoulos on "Detecting, Analyzing and Representing Vagueness in Ontologies for Facilitating Reuse"
-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 isinhibited by a variety of factors, ranging from the quality of the...

Natural Language Generation Seminar. Unger on "Conceptually scoped, modular natural language interfaces"
-Abstract: Natural language plays an increasingly important role as interface to existing services and data. However, a number of characteristics of today’s language technology make it hard to be adopted by non-linguistically skilled developers. I present an architecture that supports the easy adoption of language technology into existing applications, building...

Computing Science Seminar. Unger on "Question answering over RDF data"
-Abstract: While more and more RDF data is available, the question of how typical web users can access this body of knowledge becomes of crucial importance. There is thus a growing amount of research on natural language interfaces that allow end users to profit from the expressive power of Semantic...

A mini-workshop on Natural Language Processing and Ontologies
-There is increasing research around the integration of natural language processing and ontologies. Speaking at this mini-workshop: Invited speaker: Christina Unger "Ontology-based interpretation of natural language" Abstract: Christina will present an approach to interpreting natural language with respect to specific domain knowledge captured in ontologies. It puts ontologies at the center of...

Computing Science Seminar. Lecue on "STAR-CITY: Semantic Traffic Analytics and Reasoning for CITY"
-Abstract: This presentation outlines STAR-CITY, a system supporting semantic traffic analytics and reasoning for city. STAR-CITY, which integrates (human and machine-based) sensor data using variety of formats, velocities and volumes, has been designed to provide insight on historical and real-time traffic conditions, all supporting efficient urban planning. Our system demonstrates...

Computing Science Seminar. Power on "Ontology authoring through dialogue"
-A presentation with demos of dialogue applications to build ontologies.

Computing Science Seminar. van Gijzel on "A principled approach to the implementation of argumentation models"
-Abstract: Argumentation theory is an area that combines both philosophical concepts and computational models to deliver a practical approach to reasoning that is able to deal with uncertain information and possibly conflicting viewpoints. Structured argumentation in particular can model domain specific knowledge and argumentation schemes. However, despite these practical components, there is...
