Modeling Languages with Their Own Parameters

This repository contains all code, models, and documentation associated with the paper:

📖 Overview

This project builds multilingual word embedding models using corpora from OpenSubtitles and Wikipedia. Unlike prior work, we optimize model parameters — including embedding dimension and window size — separately for each language, improving prediction of psycholinguistic norms.

We provide:

• Optimized fastText embeddings
• Tools for training and evaluating embeddings
• A reproducible pipeline for multilingual modeling
• A Shiny app for interactive exploration COMING SOON!

🔍 Key Findings

• Default fastText settings (300d, window=5) are not optimal across languages.
• Best-performing settings vary widely by task, corpus type, and language.
• Small models (e.g., 50d, window=1) often outperform larger ones on some tasks.

📦 Repository Contents

Code is organized by pipeline stage, in the order the workflow actually runs:

workflow

• 01_corpus_preprocessing/: includes the code to download, clean, and concatenate the subtitles and wikipedia corpora into one large .txt file for the next stage of processing.

• 02_model_training: takes the finalized corpus text and trains 60 models for each language varying the window size, dimensions, and algorithm.

• 01_corpus_preprocessing/ → 02_model_training/ → 03_evaluation/: the Python pipeline that builds corpora, trains embedding models, and evaluates them against psycholinguistic norms (see word2manylanguages_workflow.ipynb for a walk-through)

• 04_visualization/: the Shiny app for interactive exploration

• 05_manuscript/: the manuscript and supporting materials

• 06_presentations/: presentations from conferences on this project

• raw/, preprocessed/, corpora/, models/, eval_inputs/, eval_results/: working folders for the Python pipeline, checked in with a single-language (Afrikaans) worked example — see raw/README.md

• download/: scripts for pulling trained models from either lab-internal storage (MinIO) or the public Zenodo archives — see download/README.md
