This paper proposes a structural analysis of two types of wh-question formation in the Austronesian languages Seediq and Tagalog. Wh-questions formed on arguments are pseudo-cleft constructions; the wh-word functions as a predicate taking the rest of the clause, in the form of a headless relative, as its subject. The restriction that argument wh-questions can only be formed on absolutives is ac...

Many natural language understanding tasks require lexicons that can support extensive lexically-based inferencing. To represent lexical semantics, most existing natural language understanding systems utilize Standard First Order Logic (FOL), or a subset of it. We argue that using a representation richer than FOL would facilitate better lexically-based inferencing. Using examples drawn from actu...
