Emping – Data Mining Tool
http://j-van-thiel.speedlinq.nl/emp/empug.html

Emping is a utility that reads a table in a csv (comma separated) format that can be generated from Open Office Calc (spreadsheet), derives all shortest rules for a selected attribute, and writes them to a .csv file that can be read by OO Calc. The shortest rules may be partially ordered by implication (entailment) and equivalence (equality) and the top level is also shown in .csv format. Optionally all logical entailments and equalities are listed too. If the data set contains ambiguous rules or more occurrences of the same rule, the user is warned. Emping is written in the functional programming language Haskell and is based on a new algoritm, which is outlined in the white paper ‘Deriving Heuristic Rules from Facts’. The paper is included in the package documentation. This has been added to Data Mining Resources Subject Tracer™ Information Blog.
