CScibox: A Software System for Age-Model Construction and Evaluation

In order to deduce the age-depth relationship in an ice or sediment core, geoscientists face a challenging forensic reasoning problem. The data are heterogeneous, noisy, and often voluminous; worse yet, the geological processes that produced those data, and that affected them between creation and sampling, are unknown.  Working backwards through all possible scenarios about the core's history involves navigating a combinatorial explosion of possibilities.  Even experts---who can quickly prune out less likely scenarios---can get overwhelmed in this situation, as can the computers that sling the data and run the equations that operationalize the hypotheses. Software support for this task is extremely limited, so very few papers in the current literature explore the space of possibilities very broadly.  I will talk about two automated reasoning tools---one complete and one under development---that use artificial intelligence techniques and modern cyberinfrastructure technology to effectively aid experts in this challenging task.
