An ontological approach for knowledge modeling and reasoning over heterogeneous crop data sources (2015)
Presentation / Conference Contribution

© Springer International Publishing Switzerland 2015. The past two decades have seen a remarkable shift in the knowledge-and information-sharing paradigm. In the crops domain, for example, the amount of information currently known about underutilized...

A logic for context-aware non-monotonic reasoning agents (2014)
Presentation / Conference Contribution

© Springer International Publishing Switzerland 2014. We develop a logical model for resource-bounded contextaware multi-agent systems which handles inconsistent context information using non-monotonic reasoning. We extend the temporal logic CTL* wit...

Advancing underutilized crops knowledge using SWRL-enabled ontologies - A survey and early experiment (2014)
Presentation / Conference Contribution

Due to their powerful knowledge representation formalism and associated inference mechanisms, ontology-based approaches have been increasingly adopted to formally represent domain knowledge. We propose the use of ontologies to advance knowledge-shari... Read More about Advancing underutilized crops knowledge using SWRL-enabled ontologies - A survey and early experiment.

A Logical Framework for the Representation and Verification of Context-aware Agents (2014)
Journal Article

© 2014, Springer Science+Business Media New York. We propose a logical framework for modelling and verifying context-aware multi-agent systems. We extend CTL∗ with belief and communication modalities, and the resulting logic 𝓛OCRS allows us t...

A temporal description logic for resource-bounded rule-based context-aware agents (2014)
Presentation / Conference Contribution

© Springer International Publishing Switzerland 2014. We propose a logical framework for modelling and verifying context-aware multi-agent systems. We extend CTL* with belief and communication modalities, and the resulting logic LOCRS allows us to de...

Improving the efficiency of Market Information Analysis Systems using GIS, Polygon and Spatial Databases (2013)
Presentation / Conference Contribution

An organization's future developments are influenced by its managements' decisions. This can only happen by strengthening research and development strategies. Market monitoring and analyzing systems are designed to provide an organized flow of inform...

A formal approach to modelling and verifying resource-bounded context-aware agents (2013)
Presentation / Conference Contribution

There has been a move of context-aware systems into safety-critical domains including healthcare, emergency scenarios, and disaster recovery. These systems are often distributed and deployed on resource-bounded devices. Therefore, developing formal t...

Formal approaches to modelling and verifying resource-bounded agents-state of the art and future prospects (2012)
Journal Article

This paper reviews formal approaches to modelling and verifying resource-bounded agents focusing on state of the Art and future prospects.

Verifying resource requirements for ontology-driven rule-based agents (2012)
Presentation / Conference Contribution

Recent efforts towards the Semantic Web have resulted in powerful languages such as Semantic Web Rule Language (SWRL) based on OWL-DL and RuleML. Rule languages and inference engines incorporate reasoning capabilities to Semantic Web application syst... Read More about Verifying resource requirements for ontology-driven rule-based agents.

Logic for coalitions with bounded resources (2011)
Journal Article

Recent work on Alternating-Time Temporal Logic and Coalition Logic has allowed the expression of many interesting properties of coalitions and strategies. However, there is no natural way of expressing resource requirements in these logics. In this a... Read More about Logic for coalitions with bounded resources.

Verifying requirements for resource-bounded agents (2011)
Thesis

This thesis presents frameworks for the modelling and verification of resource-bounded reasoning agents. The resources considered include the time, memory, and communication bandwidth required by agents to achieve a goal. The scalability and expressi...

Automated verification of resource requirements in multi-agent systems using abstraction (2011)
Presentation / Conference Contribution

We describe a framework for the automated verification of multi-agent systems which do distributed problem solving, e.g. query answering. Each reasoner uses facts, messages and Horn clause rules to derive new information. We show how to verify correc...

Resource-bounded alternating-time temporal logic (2010)
Presentation / Conference Contribution

Many problems in AI and multi-agent systems research are most naturally formulated in terms of the abilities of a coalition of agents. There exist several excellent logical tools for reasoning about coalitional ability. However, coalitional ability c... Read More about Resource-bounded alternating-time temporal logic.

Reasoning about other agents' beliefs under bounded resources (2009)
Presentation / Conference Contribution

There exists a considerable body of work on epistemic logics for bounded reasoners where the bound can be time, memory, or the amount of information the reasoners can exchange. In much of this work the epistemic logic is used as a meta-logic to reaso... Read More about Reasoning about other agents' beliefs under bounded resources.

Expressing properties of coalitional ability under resource bounds (2009)
Presentation / Conference Contribution

We introduce Coalition Logic for Resource Games (CLRG) which extends Coalition Logic by allowing explicit reasoning about resource endowments of coalitions of agents and resource bounds on strategies. We show how to express interesting properties of... Read More about Expressing properties of coalitional ability under resource bounds.

Verifying time, memory and communication bounds in systems of reasoning agents (2009)
Presentation / Conference Contribution

We present a framework for verifying systems composed of heterogeneous reasoning agents, in which each agent may have differing knowledge and inferential capabilities, and where the resources each agent is prepared to commit to a goal (time, memory a...

Verifying time and communication costs of rule-based reasoners (2009)
Presentation / Conference Contribution

We present a framework for the automated verification of time and communication requirements in systems of distributed rule-based reasoning agents which allows us to determine how many rule-firing cycles are required to solve the problem, how many me...

Verifying resource requirements for distributed rule-based systems (2008)
Presentation / Conference Contribution

Rule-based systems are rapidly becoming an important component of ‘mainstream’ computing technologies, for example in business process modelling, the semantic web, sensor networks etc. However, while rules provide a flexible way of implementing such...
