TLDR: The Dynaword approach introduces a framework for creating large-scale, continuously updated, and openly licensed datasets for NLP. It addresses issues of ambiguous licensing, static releases, and limited quality assurance by emphasizing traceable licenses, reproducibility, thorough documentation, and extensibility through community contributions. Danish Dynaword, a practical implementation, demonstrates its effectiveness by providing a significantly larger and higher-quality Danish corpus, leading to improved language model performance.
In the rapidly evolving field of natural language processing (NLP), the quality and accessibility of large-scale datasets are paramount. Traditionally, these datasets have faced significant hurdles: ambiguous licensing, static releases that hinder community contributions, and quality control limited to original publishing teams. These issues often restrict the use, sharing, and creation of derivative works, ultimately slowing down progress in AI development.
A new approach, dubbed “Dynaword,” aims to tackle these challenges head-on. Introduced by a team of researchers from Aarhus University, The Alexandra Institute, University of Copenhagen, and University of Southern Denmark, Dynaword proposes a framework for building large, open datasets that can be continuously updated through collaborative community efforts. This innovative method ensures that datasets remain relevant, high-quality, and legally sound over time.
The core of the Dynaword approach is built upon four guiding principles:
Traceable and Open Licensing
Unlike many existing datasets that rely on ambiguously licensed sources, Dynaword emphasizes openly licensed data with clear, traceable origins. This means that every piece of data included must have a documented license, ensuring it can be freely reused, reshared, and modified without legal complications. This principle directly addresses the risks associated with proprietary technology and unclear copyright, which have led to the removal or non-release of several significant datasets in the past.
Reproducibility
A key aspect of Dynaword is the ability to reproduce a substantially similar dataset. This is achieved by providing reproducible code for data collection and processing workflows. This transparency allows researchers and developers to validate the data, understand its origins, and even improve upon the collection methods, fostering a more robust and trustworthy data ecosystem.
Documentation
Following best practices in the field, Dynaword datasets are thoroughly documented. This includes detailed datasheets for each source, providing descriptions, license references, and quality checks. Comprehensive documentation makes the datasets easier to understand, use, and integrate into new projects, promoting wider adoption and collaboration.

Extensibility
Dynaword is designed to be continuously enhanced and adjusted. The framework encourages community contributions and provides clear methods for extending and improving the corpus. This ensures the dataset remains dynamic, adapting to advancements in the field and the evolving software ecosystem, much like successful open-source software projects.
To validate this approach, the researchers developed “Danish Dynaword 1,” a concrete implementation for the Danish language. This dataset serves as a practical testbed, demonstrating that the Dynaword guidelines are not just ideals but are fully implementable. Danish Dynaword is a significant achievement, containing over four times as many tokens as comparable Danish language datasets. It is exclusively openly licensed and has already received contributions from various sectors, including industry and research.
The impact of Danish Dynaword is evident in its performance. Training experiments using the Gemma-1B model showed notable improvements when using Danish Dynaword compared to previous datasets like the Danish Gigaword. Models trained on the full Danish Dynaword dataset demonstrated an average relative improvement of 5.9% for continual pre-training and a substantial 26% improvement when trained from scratch. This highlights the superior quality and utility of the Dynaword approach for language model development.
While Danish Dynaword represents a significant leap forward, the researchers acknowledge certain limitations. The dataset, despite its size, is still an order of magnitude smaller than some non-openly licensed sources like Common Crawl. Additionally, due to its strict licensing requirements, it may be biased towards domains with clear licensing, such as legal documents, with less social media content. However, the Dynaword team hopes that this project will serve as a blueprint for similar initiatives in other languages and domains, fostering a future where high-quality, permissible, and continuously evolving datasets are the norm.
