- Abstract
- Spatial assessment of environmental phenomena at regional/global scale involves the analysis and fusion
of multiple, complex, multidisciplinary, and large-scale information. Since very often reliable models of
such phenomena are lacking, the \"syndrome approach\" has been adapted to this purpose. In this context,
there is a strong need for frameworks capable of handling data from heterogeneous sources in order to
fuse them into synthetic indicators by modelling the uncertain and incomplete knowledge of the
phenomenon.
The approach here proposed models a syndrome by soft revision of bipolar information having
heterogeneous role: a set of contextual conditions constraining the flourishing of the syndrome (negative
information), identified on the basis of the expert's knowledge, and a typical pattern of notable symptoms
(positive information) that are indeed proxies of observations of the syndrome occurrence.
Specifically, three soft revision strategies are defined in the paper to combine negative and positive
information whose overall aim is to define indicators of occurrence of an environmental syndrome with
distinct objectives. The main concern of the first two revisions is to reduce the incoherence of bipolar
information by taking into account the information reliability: the first strategy models a cautious
decision attitude by eliminating incoherence and by modelling priorities of either negative or positive
information and their partial trust, while the second strategy models a cautious and precautionary
decision attitude giving credit to observations by taking into account False Negatives and False Positives.
Finally, the third strategy models decision attitudes characterized by distinct level of risk. The proposed
methodology is exemplified by a real case study whose objective is to define an indicator of the Rural
Exodus syndrome for the Mediterranean region. In this case the method fuses biophysical related variables
derived from Earth Observation (EO) data with geophysical and socioeconomic conditions based on
the proposed strategies. (literal)
