Add Problem Content
Status: Prioritization Needed
User Story
As a researcher, I want to get problem content so that I can better predict performance (e.g., in the KDD Cup task) especially when there is not existing strong KC model.

I'd like to get your method for extracting the problem descriptions from CL files in use as part of DataShop -- that is, to produce files that can be attached to associated datasets that provide the problem text information.
- Response from Ryan, May 2010
It's not that easy, unfortunately. :-| Thinking back, I think I must have had Jay step through problems rather than using a problem dump (and maybe he just looked at the first one? not clear). When I said I dumped this out via code, I think what I was thinking of was the hint messages, which I dumped out of DataShop data.
But it *is* doable, just a good bit of work. :-)
Go to C:\Program Files\Carnegie Learning\2006\Administrative\Curricula\Unit Data (or similar folder) Find the lesson of interest
Search for "problem id". Find the problems.
C:\Program Files\Carnegie Learning\2006\Administrative\Curricula\Problem Data Rename problem-data.jar to problem-data.zip, then extract it (do this on a copy) Then go into Initial State Rename initial-state.jar to initial-state.zip, then extract it Find the problem id.tre (e.g. if you are looking for problem Sys02, find sys02.tre) Search in that file for <<Scenario>> The scenario text follows (after some meta-data).
No doubt, the scenario text could be extracted from this, either via code, or undergraduate labor. Not trivial, though.
