Transforming Dependency Structures to LTAG Derivation Trees

A tree interpretation of arc standard dependency derivation

Arc-standard derivations over projective dependency trees can be interpreted as the incremental construction of lexicalized ordered trees with contiguous yields. Each \textsc{shift}, \textsc{leftarc}, and \textsc{rightar…

Configurable Dependency Tree Extraction from CCG Derivations

We revisit the problem of extracting dependency structures from the derivation structures of Combinatory Categorial Grammar (CCG). Previous approaches are often restricted to a narrow subset of CCG or support only one fl…

Using FB-LTAG Derivation Trees to Generate Transformation-Based Grammar Exercises

Transforming Dependency Structures to Logical Forms for Semantic Parsing

The strongly typed syntax of grammar formalisms such as CCG, TAG, LFG and HPSG offers a synchronous framework for deriving syntactic structures and semantic logical forms. In contrast{---}partly due to the lack of a stro…

Arc-Standard Spinal Parsing with Stack-LSTMs

We present a neural transition-based parser for spinal trees, a dependency representation of constituent trees. The parser uses Stack-LSTMs that compose constituent nodes with dependency-based derivations. In experiments…
