(YA-, after
Unix's
yacc - Yet Another
Compiler-Compiler) A humorous allusion often used in titles to
acknowledge that the topic is not original, though the content
is. As in "Yet Another AI Group" or "Yet Another
Simulated Annealing Algorithm". If used of others' work, it
describes something of which there are already far too many.
In hackish acronyms the "YA" prefix almost invariably expands
to
Yet Another, e.g.
YABA,
YAUN.
