This is an list of known tools and resources developed specifically to do linguistic processing in Icelandic. It is intended to give readers a clear overview of the ever-growing arsenal of tools for working with Icelandic natural language data at a glance.
This list is categorized by task to increase clarity. Due to that, some multi-functional tools and toolkits might appear more than once in the list. If you notice a category or resource is missing or have suggestions on how to improve this list, please open a GitHub pull request. For those who do not know how to make pull requests, you can also create an issue with your GitHub account.
