The Artificial Intelligence Laboratory proposes to continue its work on a group of closely interconnected projects, all bearing on questions about how to make computers able to use more sophisticated kinds of knowledge to solve difficult problems. This proposal explains…

In this work we present a method to calculate the spectrum of the fundamental primaries of a digital camera from the experimental knowledge of its spectral sensitivities. The color triangle of the camera, linked to the chromaticities of its primaries,…

The appearance and continuous growth of virtual communities on the web imposes the challenge of coping with the large amount of information and knowledge these communities produce. The Semantic Web with its set of standards and technologies provides the basic…

The use of clocks for timekeeping seems to be a straightforward and almost intuitive routine. Glancing at mechanical clocks designed in Edo period Japan, however, we witness how modern-day intuitions betray our attempts to understand devices created in a culture…

Current theories of physics cognition require specification of complex mechanisms for explaining knowledge acquisition. I demonstrate that a quantitative model of physics perception can be constructed by assuming that physics problem perception provides an optimal summary of a set of…

The goal of this work involves the developing of an argumentation-based formalism that an agent could use for constructing plans. In this formalism, agents will have certain knowledge about the world, and a set of actions that they will be…

This paper focuses on the role of food tourism in delivering sustainability agendas by examining how the agriculture and tourism sectors have struggled to realise measurable successes because of constraints, conflicting ambitions and low levels of social capital. It focuses…

Malaria is the most important parasite species of humans, affecting more than 2.2 billion people, and causing hundreds of millions of clinical cases and around one million deaths every year. Since the 1940s, mass-produced, inexpensive drugs have been available that…

Due to the dynamic nature of the Web as well as its heterogeneous audience, web applications are more likely to rapidly evolve leading to inconsistencies among requirements during the development process. With the purpose to deal with these inconsistencies, web…
