Korean and Spanish psych-verbs: Interaction of case, theta-roles, linearization, and event structure in HPSG

In this paper, we argue that by making a more detailed distinction of theta-roles, while at the same time investigating the correlation of case marking, theta-role assignment, and eventuality types, we can describe different psych-verb subclasses and explain their alignment patterns in Spanish and Korean. We propose a neo-Davidsonian treatment of psych-verbs in HPSG that allows us to account for the underspecification of theta-roles which are modeled in an inheritance hierarchy for semantic relations. By assuming linking properties modeled lexically, we can constrain the properties for psych-verbs which shows the mapping of semantic arguments (i.e. experiencer, stimulus-causer, subject matter and target) to the elements in the argument structure. The type hierarchy and lexical rules proposed here capture the alternation in case marking not only of the experiencer (as traditionally assumed in the literature), but also of the stimulus. This analysis leads us to a new fourfold classification of psych-verbs for both languages.
