1. Acute Inflammations: The data was created by a medical expert as a data set to test the expert system, which will perform the presumptive diagnosis of two diseases of the urinary system.

2. Annealing: Steel annealing data

3. Arrhythmia: Distinguish between the presence and absence of cardiac arrhythmia and classify it in one of the 16 groups.

4. Credit Approval: This data concerns credit card applications; good mix of attributes

5. Cylinder Bands: Used in decision tree induction for mitigating process delays known as "cylinder bands" in rotogravure printing

6. Dermatology: Aim for this dataset is to determine the type of Eryhemato-Squamous Disease.

7. Echocardiogram: Data for classifying if patients will survive for at least one year after a heart attack

8. Flags: From Collins Gem Guide to Flags, 1986

9. Heart Disease: 4 databases: Cleveland, Hungary, Switzerland, and the VA Long Beach

10. Hepatitis: From G.Gong: CMU; Mostly Boolean or numeric-valued attribute types; Includes cost data (donated by Peter Turney)

11. Horse Colic: Well documented attributes; 368 instances with 28 attributes (continuous, discrete, and nominal); 30% missing values

12. Japanese Credit Screening: Includes domain theory (generated by talking to Japanese domain experts); data in Lisp

13. Mechanical Analysis: Fault diagnosis problem of electromechanical devices; also PUMPS DATA SET is newer version with domain theory and results

14. Meta-data: Meta-Data was used in order to give advice about which classification method is appropriate for a particular dataset (taken from results of Statlog project).

15. Pittsburgh Bridges: Bridges database that has original and numeric-discretized datasets

16. Statlog (Australian Credit Approval): This file concerns credit card applications. This database exists elsewhere in the repository (Credit Screening Database) in a slightly different form

17. Statlog (German Credit Data): This dataset classifies people described by a set of attributes as good or bad credit risks. Comes in two formats (one all numeric). Also comes with a cost matrix

18. Statlog (Heart): This dataset is a heart disease database similar to a database already present in the repository (Heart Disease databases) but in a slightly different form

19. Teaching Assistant Evaluation: The data consist of evaluations of teaching performance; scores are "low", "medium", or "high"

20. University: Data in original (LISP-readable) form

21. Zoo: Artificial, 7 classes of animals
