%       Expertise. Technical Report: EDRC 12-34-89, Engineering Design
%       Research Center, Carnegie Mellon University, Pittsburgh, PA.

%       -- Describes a new design method with Bridger (variant of COBWEB) using
% 	 this domain. (Also an EDRC report: 12-35-89)

% 	 (V1 and V2) of the database
%

%       Unpublished Manuscript.
%       -- Results using 10 random 10-fold cross-validation test with Bridger
% 	 (relative error rate):
% 	 Version V1 of the database: 
% 	 MATERIAL 18.4%, REL-L 38.7%, SPAN 42.7%, T-OR-D 14.7%, TYPE 47.6%.
% 	 Version V2 of the database:
% 	 MATERIAL 24.2%, REL-L 41.7%, SPAN 39.9%, T-OR-D 14.7%, TYPE 56.5%.
% 
%    -- Quinlan (1989) Personal communication. 
%       -- Results of a 10-fold cross-validation test with C4.5, and with
%          a separate decision tree for each design property obtained the 
% 	 following error rates on version V1 of the database:
% 	 MATERIAL 15%, REL-L 32%, SPAN 32%, T-OR-D 15%, TYPE 44%.
% 
% 4. Number of instances: 108
% 
% 5. Relevant Information:
%    
%    There are two versions to the database: 
%       V1 contains the original examples and 
%       V2 contains descriptions after discretizing numeric properties.
% 
%    There are no ``classes'' in the domain. Rather this is a DESIGN domain where
%    5 properties (design description) need to be predicted based on 7 
%    specification properties.
% 
% 6. Number of Attributes: 13: 7 specifications, 5 design description, and 1
%    identifier (not used for the classification)
% 
% 7. Attribute Information:  
% 
%    The type field state whether a property is continuous/integer (c) 
% 						      or nominal (n).
%    For properties with c,n type, the range of continuous numbers is given 
%    first and the possible values of the nominal follow the semi-colon.

% 
% 
% 8. More complicated attributes:
% 
%    One can use a hierarchical structure for the Type property. There are two
%    options.
% 
% 	option 1 (use examples without modification)
%         --------
% 
% 			Type 
% 	     /      /	     \     \
% 	   /       /	      \	     \
% 	wood	suspen		arch	truss
% 				       /  |    \
% 				     /    |      \
% 				cantilev  cont-t   simple
% 
% 
% 	option 2 (requires changes in the Type property - specified bellow)
% 	--------
% 
% 				Type 
% 
% 		 /     	/        |	    	    \	
% 	   	/     /	         |   		     \
% 	    wood   suspen	arch		      truss
% 				/ \	    	   /  |  \    \
% 			      /	    \	  	 /    |   \	\
% 			tied-a    not-tied  cantilev cont-t simple arch-t
% 
% 
% 	Change the Type  property of the following examples (in both V1 and V2):
% 		E28   ->  arch-t
% 		E91,E90,E84,E83,E73  -> tied-a
% 		E97,E78,E77,E75,E66,E64,E43  -> not-tied
