Norwegian Large-scale Language Models

Welcome to the emerging collection of large-scale contextualized language models for the Norwegian language. NorLM (or, more recently, NORA.LLM) originated as joint initiative of the projects EOSC-Nordic (European Open Science Cloud), SANT (Sentiment Analysis for Norwegian), and HPLT (High-Performance Language Technologies), in collaboration with the AI Laboratory of the National Library of Norway and the National e-Infrastructure Services, coordinated by the Language Technology Group (LTG) at the University of Oslo.

We are working to provide these models and supporting tools for researchers and developers in Natural Language Processing (NLP) for the Norwegian language. We do so in the hope of facilitating scientific experimentation with and practical applications of state-of-the-art NLP architectures, as well as to enable others to develop their own large-scale models, for example for domain- or application-specific tasks, language variants, or even other languages than Norwegian.

Under the auspices of the NLPL use case in EOSC-Nordic, we are coordinating with colleagues in Denmark, Finland, and Sweden on a collection of large contextualized language models for the Nordic languages, including language variants or related groups of languages, as linguistically or technologically appropriate.

Available Models

At this initial stage of development, Norwegian models for two common architecture variants are available:

• NorELMo: LSTM-Based Architectures
• NorBERT: Transformer-Based Architectures
• NorT5: Combined encoder–encoder architecture
• NorGPT: Generative language models (BLOOM- and Mistral-like)

We emphatically welcome all kinds of user feedback, including of course suggestions for improvement or suggestions for additional types of Norwegian contextualized language models or associated tools. Please contact us via the NorLM technical coordinator, Andrey Kutuzov.

License and Access

All Norwegian language models from the NorLM initiative are publicly available for download from the NLPL Vectors Repository, with a CC BY 4.0 license. The NorBERT model is also included with the Huggingface Transformers Library.

To receive announcements of updates and availability of additional models, please self-subscribe to our very low-traffic NorLM mailing list.
