## An Example on Generating Model Parameter Estimation from Formal
Ecological Data Descriptions

**Virginia Brilhante**
In the investigation of ecological modeling automation, one must
consider the estimation of model parameters -
a key task in many maths oriented modeling paradigms. This talk
presents an exploratory example where a
parameter estimation process is automatically generated based on
declarative formal descriptions of the
properties of the data set (ecological meta-data) at hand. The
ecological properties are described through
classes and relations provided by the Ecolingua Ontology. A small
Definite Clause Grammar is used to infer the
parameter estimation process; by means of this simple logic-based
formalism we are able to reconstruct the
inferences that a human modeler would possibly perform to estimate the
parameter.

The example is a small demonstration of the feasibility of relating
ecological meta-data to model design, which is
our ultimate goal.
