BACKGROUND At present, we have very limited ability to compare public health activity across jurisdictions and countries, or even to ascertain differences in what is considered to be a public health activity. Existing standardised health classifications do not capture important dimensions of public health, which include its functions, the methods and interventions used to achieve these, the hea...

During the last few years, a number of works aiming at interfacing ontologies and lexical resources have been initiated. This paper aims at clarifying the current picture of this domain. It compares ontologies built following different methodologies and analyses their combination with lexical resources. A point defended in the paper is that different methodologies lead to very different charact...

Today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. The optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. Using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. Nebka ...

We investigate the geometry of finite datasets defined by equilibrium prices, income distributions, and total resources. We show that the equilibrium condition imposes no restrictions if total resources are collinear, a property that is robust to small perturbations. We also show that the set of equilibrium datasets is pathconnected when the equilibrium condition does impose restrictions on dat...

Usually one can quantify the subjective notion of useful information in two different perspectives: static resources – measuring the amount of planing required to construct the object; or dynamic resources – measuring the computational effort required to produce the object. We study the robustness of logical depth measuring dynamic resources, proving that small variations in the significance le...

Besides the lexical ontology itself, during the Onto.PT project other resources were developed. Those included handcrafted grammars for extracting semantic relations, a term-based lexicalsemantic network extracted from dictionaries, a thesaurus with fuzzy memberships, polarities assigned to the Onto.PT synsets, as well as resources used for evaluation, such as manual mappings between words and ...

The Mediterranean regions are submitted to a large variety of climates. In general, the environments are arid and semi-arid with summers characterised by high temperatures and small precipitation. Due to the scarcity of water resources, the correct evaluation of water losses by the crops as evapotranspiration (ET) is very important in these regions. In this paper, we initially present the most ...

When users need multiple devices or other resources in a dynamic, connected environment the identification and the selection of these devices are crucial factors before the user can engage in the actual task. Of particular interest are cases in which multiple users are working in the same environment because that may induce conflicts regarding device usage. In this paper, we propose a categoriz...
