Evaluating Induced CCG Parsers on Grounded Semantic Parsing

2016

We compare the effectiveness of four different syntactic CCG parsers for a semantic slotfilling task to explore how much syntactic supervision is required for downstream semantic analysis. This extrinsic, task-based evaluation also provides a unique …

Data Augmentation via Dependency Tree Morphing for Low-Resource Languages

2018

Neural NLP systems achieve high scores in the presence of sizable training dataset. Lack of such datasets leads to poor system performances in the case low-resource languages. We present two simple text augmentation techniques using …

Transforming Dependency Structures to Logical Forms for Semantic Parsing

2016 · Transactions of the Association for Computational Linguistics

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 strong …
