We investigate the possibility of constructing an Abstract Categorial Grammar (ACG) that relates Tree Adjoining Grammar (TAG) and Higher Order Logic (HOL) formulas encoding Abstract Meaning Representations (AMRs). We also propose another ACG that relates TAG and HOL formulas expressing the neo-Davidsonian event semantics. Both of these encodings are based on the already existing ACG encoding of the syntax-semantics interface where TAG derivations are interpreted as HOL formulas representing Montague semantics. In particular, both of these encodings share the same abstract language coming from the ACG encoding of TAG with Montague semantics, which is second-order. For second-order ACGs, problems of parsing and generation are known to be of polynomial complexity. Thus we get the natural language generation and parsing with TAGs and HOL formulas modeling AMR for free.
