Synthetic Data in the Era of Large Language Models (2025.acl-tutorials)
Copied to clipboard
| Challenge: | 'synthetic data' is a data generated with the assistance of large language models to make dataset construction faster and cheaper. |
| Approach: | This tutorial seeks to build a shared understanding of recent progress in synthetic data generation from NLP and related fields by grouping and describing major methods, applications, and open problems. |
| Outcome: | This tutorial will describe methods, applications, and open problems that have been developed and are being used to improve the quality and efficiency of synthetic data generation. |
CitationIE: Leveraging the Citation Graph for Scientific Information Extraction (2021.acl-long)
Copied to clipboard
| Challenge: | Existing work on scientific information extraction (SciIE) considers extraction solely based on the content of an individual paper, without considering the paper’s place in the broader literature. |
| Approach: | They propose to automate the extraction of key information from scientific documents by leveraging a complementary source: the citation graph of referential links between citing and cited papers. |
| Outcome: | The proposed model improves on a set of English-language scientific documents. |

Seungone Kim, Juyoung Suk, Xiang Yue, Vijay Viswanathan, Seongyun Lee, Yizhong Wang, Kiril Gashteovski, Carolin Lawrence, Sean Welleck, Graham Neubig
| Challenge: | Prior studies have focused on developing effective data generation methods, but lack systematic comparison of different LMs as data generators in a unified setting. |
| Approach: | They propose to use a benchmark to compare language models' data generation abilities against a set of standardized settings and metrics. |
| Outcome: | The proposed benchmark provides standardized settings and metrics to evaluate LMs’ data generation abilities. |
DataFinder: Scientific Dataset Recommendation from Natural Language Descriptions (2023.acl-long)
Copied to clipboard
| Challenge: | Modern machine learning relies on datasets to develop and validate research ideas. |
| Approach: | They propose a dataset recommendation system that uses a training set and an evaluation set to help people find relevant datasets. |
| Outcome: | The proposed model finds more relevant search results than existing third-party search engines. |

Ian Wu, Sravan Jayanthi, Vijay Viswanathan, Simon Rosenberg, Sina Pakazad, Tongshuang Wu, Graham Neubig
| Challenge: | Multimodal Retrieval Augmented Generation (MMRAG) is a powerful approach to question-answering over multimodal documents. |
| Approach: | They propose a synthetic data generation framework that leverages interplay between a retriever, large language model and large multimodal model to generate question and answer pairs directly from multimodal documents. |
| Outcome: | The proposed framework generates question and answer pairs from 1024 questions over Wikipedia documents and evaluates state-of-the-art models using it. |

Aryeh Tiktinsky, Vijay Viswanathan, Danna Niezni, Dana Meron Azagury, Yosi Shamay, Hillel Taub-Tabib, Tom Hope, Yoav Goldberg
| Challenge: | Combination therapies are becoming standard of care for diseases such as cancer, tuberculosis, malaria and HIV. |
| Approach: | They construct an expert-annotated dataset for extracting drug combinations from the scientific literature. |
| Outcome: | The proposed dataset is the first relation extraction dataset consisting of variable-length relations. |
Prompt2Model: Generating Deployable Models from Natural Language Instructions (2023.emnlp-demo)
Copied to clipboard
| Challenge: | Large language models (LLMs) are a step backward from traditional special-purpose NLP models . they require extensive computational resources for deployment and can be gated behind APIs . |
| Approach: | They propose a general-purpose method that takes a natural language task description and uses it to train a special-purpose model. |
| Outcome: | The proposed method outperforms a strong LLM by 20% while being 700 times smaller. |
Better Synthetic Data by Retrieving and Transforming Existing Datasets (2024.findings-acl)
Copied to clipboard
| Challenge: | despite advances in large language models, task-specific data is not available for many use cases . a new method to improve automated dataset generation uses publicly available datasets . |
| Approach: | They propose a method to make better use of existing datasets to improve automatic dataset generation. |
| Outcome: | The proposed method outperforms existing methods on language-based tasks . it significantly increases diversity and difficulty of generated data on many tasks compared to other methods . |
DataLab: A Platform for Data Analysis and Intervention (2022.acl-demo)
Copied to clipboard
Yang Xiao, Jinlan Fu, Weizhe Yuan, Vijay Viswanathan, Zhoumianze Liu, Yixin Liu, Graham Neubig, Pengfei Liu
| Challenge: | Existing tools and research focus on how to interpret and manipulate data, despite its crucial role in machine learning, . existing tools and researchers focus on systems on top of existing data, rather than how to use it. |
| Approach: | They propose a unified data-oriented platform that allows users to interactively analyze the characteristics of data and provides a standard interface for many data processing operations. |
| Outcome: | The proposed platform allows users to analyze the characteristics of data and provides a standardized interface so that many data processing operations can be provided within a single interface. |
