WILBUR: Adaptive In-Context Learning for Robust and Accurate Web Agents

no code implementations8 Apr 2024 Michael Lutz, Arth Bohra, Manvel Saroyan, Artem Harutyunyan, Giovanni Campagna

In the realm of web agent research, achieving both generalization and accuracy remains a challenging problem.

ThingTalk: An Extensible, Executable Representation Language for Task-Oriented Dialogues

1 code implementation23 Mar 2022 Monica S. Lam, Giovanni Campagna, Mehrad Moradshahi, Sina J. Semnani, Silei Xu

Task-oriented conversational agents rely on semantic parsers to translate natural language to formal representations.

Contextual Semantic Parsing for Multilingual Task-Oriented Dialogues

1 code implementation4 Nov 2021 Mehrad Moradshahi, Victoria Tsai, Giovanni Campagna, Monica S. Lam

On RiSAWOZ, CrossWOZ, CrossWOZ-EN, and MultiWOZ-ZH datasets we improve the state of the art by 11%, 17%, 20%, and 0. 3% in joint goal accuracy.

Grounding Open-Domain Instructions to Automate Web Support Tasks

1 code implementation NAACL 2021 Nancy Xu, Sam Masling, Michael Du, Giovanni Campagna, Larry Heck, James Landay, Monica S Lam

RUSS consists of two models: First, a BERT-LSTM with pointers parses instructions to ThingTalk, a domain-specific language we design for grounding natural language on the web.

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.

Zero-Shot Transfer Learning with Synthesized Data for Multi-Domain Dialogue State Tracking

1 code implementation ACL 2020 Giovanni Campagna, Agata Foryciarz, Mehrad Moradshahi, Monica S. Lam

We show that data augmentation through synthesized data can improve the accuracy of zero-shot learning for both the TRADE model and the BERT-based SUMBT model on the MultiWOZ 2. 1 dataset.

Schema2QA: High-Quality and Low-Cost Q&A Agents for the Structured Web

3 code implementations16 Jan 2020 Silei Xu, Giovanni Campagna, Jian Li, Monica S. Lam

The key concept is to cover the space of possible compound queries on the database with a large number of in-domain questions synthesized with the help of a corpus of generic query templates.

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.
