Extracted alternations are represented as the tuple ( [SUFF], [ARGS], SCORE), where SUFF is the directed non-corresponding suffix component between alternates, ARGS is the directed case slot correspondence and SCORE is a numeric statement of the plausibility of the alternation, SCORE E [0, 1].
for example, we represent the alternation (2a) (2b) from above as:5 the verbs for the base and target case frames coincide, the base nominative (ga) case slot is deleted, and the base accusative (o) case slot alternates with the target nominative (ga) case slot.
