An ActOn-based semantic information service for Grids
(2010)We describe a semantic information service that aggregates metadata from a large number of information sources of a large-scale Grid infrastructure. It uses an ontology-based information integration architecture (ActOn) ...

Architectural support for data-driven execution
(2014)The exponential growth of sequential processors has come to an end, and thus, parallel processing is probably the only way to achieve performance growth. We propose the development of parallel architectures based on ...

Argumentation and temporal persistence
(2011)We study how the problem of temporal projection can be formalized in terms of argumentation. In particular, we extend earlier work of translating the language E for Reasoning about Actions and Change into a Logic Programming ...

Argumentation based modelling of embedded agent dialogues
(2006)This paper presents a novel approach to modelling embedded agent dialogues. It proposes a specific structure for the supporting information accompanying the arguments that agents exchange during a dialogue, it defines ...

Article
Argumentation Logic
(2014)We propose a novel logic-based argumentation framework, called Argumentation Logic (AL), built upon a restriction of classical Propositional Logic (PL) as its underlying logic. This allows us to control the application of ...

Brain and behavioral correlates of action semantic deficits in autism
(2013)Action-perception circuits containing neurons in the motor system have been proposed as the building blocks of higher cognition; accordingly, motor dysfunction should entail cognitive deficits. Autism spectrum conditions ...

Brain routes for reading in adults with and without autism: EMEG evidence
(2014)Reading utilises at least two neural pathways. The temporal lexical route visually maps whole words to their lexical entries, whilst the nonlexical route decodes words phonologically via parietal cortex. Readers typically ...

Communities: Concept-based querying for mobile services
(2005)In this paper, we consider semantic service discovery in a global computing environment. We propose creating a dynamic overlay network by grouping together semantically related services. Each such group is termed a community. ...

Article
Comparison of collaborative and content-based automatic recommendation approaches in a digital library of Serbian PhD dissertations
(2017)Digital libraries have become an excellent information resource for researchers. However, users of digital libraries would be served better by having the relevant items ‘pushed’ to them. In this research, we present various ...

Article
The computational value of joint consistency
(1994)In this paper we investigate the complexity of some recent reconstructions of Reiter's Default Logic using graph-theoretical structures. It turns out that requiring joint consistency of the justification of the applied ...

Article
Computing the acceptability semantics
(1995)We present a proof theory and a proof procedure for nonmonotonic reasoning based on the acceptability semantics for logic programming, formulated in an argumentation framework. These proof theory and procedure are defined ...

A core grid ontology for the semantic grid
(2006)In this paper, we propose a Core Grid Ontology (CGO) that define s fundamental Grid-specific concepts, and the relationships between them. One of the key goals is to make this Core Grid Ontology general enough and easily ...

Cultural journeys in the information society
(IEEE, 2000)This paper describes the Cultural Journeys in the Information Society (CJIS) project. CJIS project is an INCO project (973324) funded by the ECC and its aims to address the problem of electronic information roads at various ...

DBGlobe: A service-oriented P2P system for global computing
(2003)The challenge of peer-to-peer computing goes beyond simple file sharing. In the DBGlobe project, we view the multitude of peers carrying data and services as a super-database. Our goal is to develop a data management system ...

The Electronic Road: Personalized Content Browsing
(2003)The effectiveness of a content browsing system, based on semantic content analysis, user profiling, and adaptation, is discussed. The various aspects of electronic road are also described. An user's navigation path through ...

Article
Encoding planning problems in nonmonotonic logic programs
(1997)We present a framework for encoding planning problems in logic programs with negation as failure, having computational efficiency as our major consideration. In order to accomplish our goal, we bring together ideas from ...

Experiences from developing a distributed context management system for enabling adaptivity
(2007)Today, one can observe an ever increasing trend in the use of mobile systems. This change inevitably affects the software running on such devices by necessitating additional functionality such as context awareness and ...

Article
Exploiting course grain parallelism from FORTRAN by mapping it to IF1
(1998)FORTRAN, a classical imperative language is mapped into IF1, a machine-independent dataflow graph description language with Single Assingment Semantics (SAS). Parafrase 2 (P2) is used as the front-end of our system. It ...

Exploring content dependencies to better balance performance and freshness in web database applications
(2012)In this paper, we present a novel approach for materializing dynamic web pages by exploiting content dependencies and user access patterns. We introduce two new semantic-based data freshness metrics and show that our ...
