    Data Set 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.


    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.

    Name / Type / Possible values / Comments

      1.  IDENTIF / -- / -- / identifier of the examples
      2.  RIVER / n / A, M, O / --
      3.  LOCATION / n / 1 to 52 / --
      4.  ERECTED / c,n / 1818-1986 ; CRAFTS, EMERGING, MATURE, MODERN / --
      5.  PURPOSE / n / WALK, AQUEDUCT, RR, HIGHWAY / --
      6.  LENGTH / c,n / 804-4558 ; SHORT, MEDIUM, LONG / --
      7.  LANES / c,n / 1, 2, 4, 6 ; 1, 2, 4, 6 / --
      8.  CLEAR-G / n / N, G / --
      9.  T-OR-D / n / THROUGH, DECK / --
      10. MATERIAL / n / WOOD, IRON, STEEL / --
