Optimality "Theory" as a Relational Network TheorEM Good work has been done in Optimality Theory (OT), one of the newer branches of generative phonology. Milnes and Wiltshire 2000 (MW) provide an OT description of the phonology of Russian accentology. The present study demonstrates that a generalized relational network (RN) description of the same data not only predicts the correct accent placement but also the OT constraints and their ordering. Accent placement, the constraints, and their relative order emerge from the network. OT is thus derivable from an RN theory. MW is based on a Laszlo-Ivsic (LI) description of the accent patterns in the Russian a-stem declension as seen in kajma 'edge' (word-final accent throughout), zaba 'toad' (stem accent throughout), and zena 'wife', zima 'winter', and ruka 'hand, arm' (all with movable accent). An LI description assumes that morphemes are marked for simultaneous stress, for stress on the following morpheme, for stress on the preceding morpheme (in derivation only), or are unmarked for stress. Morphemic words, which are the input to the phonology, may therefore be marked for zero, one, or more stresses. The phonology then sorts out the stresses, picks the correct one, and deletes the others. MW use a series of OT constraints, some established, some modified. The RN description is based on the traditional formulation that Russian stress is free and phonemic. (It is also called "mobile," but that refers to morphological paradigms and is handled by a variant of the LI description.) The RN description says 1) that a phonological word in Russian has 0-m unaccented syllables followed by one accented syllable followed by 0-n unaccented syllables, and 2) that any given occurrence of morphological accent is realized as either a phonological accent or as zero. This predicts the correct accents, and a minor modification of the network provides a phonological accent for morphological words with no stress. Certain details of the network hierarchy are shown to correspond to the OT constraints and to predict the hierarchy between them given in MW. This can be done for OT descriptions of different phonological phenomena in unrelated languages (e.g. Korean coda simplification). Thus OT descriptions do not require the assumptions of generative phonology and OT itself is derivable from an RN theory. It is, in short, a theorEM of a RN theorY.
