Localizing Open-Ontology QA Semantic Parsers in a Day Using Machine Translation

1 code implementation EMNLP 2020 Mehrad Moradshahi, Giovanni Campagna, Sina J. Semnani, Silei Xu, Monica S. Lam

We propose Semantic Parser Localizer (SPL), a toolkit that leverages Neural Machine Translation (NMT) systems to localize a semantic parser for a new language.

A Few-Shot Semantic Parser for Wizard-of-Oz Dialogues with the Precise ThingTalk Representation

1 code implementation Findings (ACL) 2022 Giovanni Campagna, Sina J. Semnani, Ryan Kearns, Lucas Jun Koba Sato, Silei Xu, Monica S. Lam

Previous attempts to build effective semantic parsers for Wizard-of-Oz (WOZ) conversations suffer from the difficulty in acquiring a high-quality, manually annotated training set.

Genie: A Generator of Natural Language Semantic Parsers for Virtual Assistant Commands

1 code implementation18 Apr 2019 Giovanni Campagna, Silei Xu, Mehrad Moradshahi, Richard Socher, Monica S. Lam

We advocate formalizing the capability of virtual assistants with a Virtual Assistant Programming Language (VAPL) and using a neural semantic parser to translate natural language into VAPL code.
