DaCy: A SpaCy NLP Pipeline for Danish

DaCy is a Danish preprocessing pipeline trained in SpaCy. It has achieved State-of-the-Art performance on Named entity recognition, part-of-speech tagging and dependency parsing for Danish. This repository contains material for using the DaCy, reproducing the results and guides on usage of the package. Furthermore, it also a behavioural test for biases and robustness of Danish NLP pipelines.

🔧 Installation

To get started using DaCy simply install it using pip by running the following line in your terminal:

pip install dacy

pip install dacy[all]

git clone https://github.com/KennethEnevoldsen/DaCy.git
cd DaCy
pip install .

👩‍💻 Usage

To use the model you first have to download either the small, medium, or large model. To see a list of all available models:

import dacy
for model in dacy.models():
    print(model)
# da_dacy_small_tft-0.0.0
# da_dacy_medium_tft-0.0.0
# da_dacy_large_tft-0.0.0

To download and load a model simply execute:

nlp = dacy.load("da_dacy_medium_tft-0.0.0")

Which will download the model to the .dacy directory in your home directory.

To download the model to a specific directory:

dacy.download_model("da_dacy_medium_tft-0.0.0", your_save_path)
nlp = dacy.load_model("da_dacy_medium_tft-0.0.0", your_save_path)

👩‍🏫 Tutorials and documentation

DaCy also includes a detailed documentation as well as a series of Jupyter notebook tutorial. If you do not have Jupyter Notebook installed, instructions for installing and running it can be found here. All the tutorials are located in the tutorials folder.

🦾 Performance and Training

The following table shows the performance on the DaNE test set when compared to other models. Highest scores are highlighted with bold and second highest is underlined.

Stanza uses the spacy-stanza implementation. The speed on the DaNLP model is as reported by the framework, which does not utilize batch input. However, given the model size, it can be expected to reach speeds comparable to DaCy medium. Empty cells indicate that the framework does not include the specific model.

Robustness and Biases

DaCy compares the performance of Danish language processing pipeline under a large variaty of augmentations to test the robustness and biases hereof. To find out more please check the website.

Does DaCy run on X?

DaCy is intended to run on all major OS, this includes Windows (latest version), MacOS (Catalina) and the latest version of Linux (Ubuntu). Below you can see if DaCy passes its test suite for the system of interest. The first one indicated Linux. Please note these are only the systems DaCy is being actively tested on, if you run on a similar system (e.g. an earlier version of Linux) DaCy will likely run there as well.

Acknowledgements

DaCy is a result of great open-source software and contributors. It wouldn't have been possible without the work by the SpaCy team which developed an integrated the software. Huggingface for developing Transformers and making model sharing convenient. BotXO for training and sharing the Danish BERT model and Malte Hojmark-Bertelsen for making it easily available and developing Ælæctra. A huge compliment also goes out to DaNLP which have made it easy to get access to Danish resources and even supplied some of the tagged data themselves.
