Deterministic Statistical Mapping of Sentences to Underspecified Semantics

Learning Dependency-Based Compositional Semantics

“…DCS has a family resemblance to a semantic representation called natural logic form (Alshawi et al, 2011), which is also motivated by the benefits of working with dependency-based logical forms. The goals and the detailed structure of the two semantic formalisms are different, however.…”

“…The goals and the detailed structure of the two semantic formalisms are different, however. Alshawi et al (2011) focuses on parsing complex sentences in an open domain where a structured database or world does not exist. While they do equip their logical forms with a full model-theoretic semantics, the logical forms are actually closer to dependency trees: quantifier scope is left unspecified, and the predicates are simply the words.…”

A Discriminative Graph-Based Parser for the Abstract Meaning Representation

“…In contrast, semantic dependency parsing-in which the vertices in the graph correspond to the words in the sentence-is meant to make semantic parsing feasible for broader textual domains. Alshawi et al (2011), for example, use shift-reduce parsing to map sentences to natural logical form.…”
