Latvian SpaCy Model: lv_spaCy_CNN

GitHub Repo

https://github.com/JesseLau24/Fengdi_Huang_Master_Thesis_Repo

Overview

This is a spaCy pipeline for Latvian, built with the spaCy Tok2Vec CNN backbone.

It includes the following components:

Tok2Vec (spaCy Tok2Vec CNN)
Tagger
Morphologizer
Parser
Sentence Segmenter (senter)
Lemmatizer

Model type: spaCy CNN Pipeline Language: Latvian (lv)
Recommended hardware: CPU for small-scale use, GPU recommended for faster inference.

Training Data

The model was trained on the Latvian UD Treebank v2.16, which is derived from the Latvian Treebank (LVTB) created at the University of Latvia, Institute of Mathematics and Computer Science, Artificial Intelligence Laboratory (AI Lab).

Dataset source: UD Latvian LVTB
License: CC BY-SA 4.0
Data splits:
- Train: 15,055 sentences
- Dev: 2,080 sentences
- Test: 2,396 sentences

Acknowledgements

Thanks to the University of Latvia, AI Lab, and all contributors of the Latvian UD Treebank.
Inspired by the spaCy ecosystem and training framework.
The Latvian UD Treebank was developed with support from multiple grants, including:
- European Regional Development Fund (Grant No. 1.1.1.1/16/A/219, 1.1.1.2/VIAA/1/16/188)
- State Research Programme "National Identity"

Usage

You can:

Download the model directly from the Hugging Face Hub
Using huggingface_hub.snapshot_download, the model files will be automatically fetched and cached locally.

  ```python
  import spacy
  from huggingface_hub import snapshot_download
  
  # Load the pipeline
  model_dir = snapshot_download(repo_id="JesseHuang922/lv_spacy_cnn_1pct", repo_type="model")
  nlp = spacy.load(model_dir)
  ```
