ad-hockery
 /ad?hok'@r?ee/, n.

    [Purdue]

    1. Gratuitous assumptions made inside certain programs, esp. expert
    systems, which lead to the appearance of semi-intelligent behavior but are
    in fact entirely arbitrary. For example, fuzzy-matching of input tokens
    that might be typing errors against a symbol table can make it look as
    though a program knows how to spell.

    2. Special-case code to cope with some awkward input that would otherwise
    cause a program to choke, presuming normal inputs are dealt with in some
    cleaner and more regular way.

    Also called ad-hackery, ad-hocity (/ad-hos'@-tee/), ad-crockery. See also 
    ELIZA effect.
