our group at Duke is currently attempting to connect two data sets fed through a web-based system, one containing research questions (i.e., variables positioned with certain roles) and a database of statistical methods. this connection is done informally in a number of R packages and related software such as Rcmdr, R4calc, and Rkward where a variable of a certain type is matched to a certain test. For example, a logistic regression model requires a dichotomous variable as its dependent variable. our goal is to formalize this link through a computational ontology, which would standardize and hopefully facilitate package and library development for R.

we have started some parallel efforts regarding both our requirements for this ontology as well a search for existing ontologies. So far we couldn't find any existing ontology, which seems odd given the widespread application such an ontology has

Question for the list members: Is anybody aware of any existing ontologies computational focusing on this topic?
