The Multi-Lingual Document Classifier is a machine learning project that uses Tokenization module and Evaluation metrics, built and evaluated with spaCy / NLTK. It follows a reproducible, modular workflow where data preparation, model training, evaluation, and serving stay clearly separated. The project emphasizes solid engineering alongside modelling, so it can be extended, retrained, and presented confidently as a final year capstone.
Existing approaches to this problem are often manual, inconsistent, and unable to scale with larger or noisier data. Without a data-driven system built on Evaluation metrics and spaCy / NLTK, decisions are slow and prone to bias, and there is no structured way to measure performance or adapt to changing patterns over time.
This project develops an end-to-end ML solution that ingests data through Tokenization module, builds and tunes a model with spaCy / NLTK, and exposes results through Demo interface. The workflow is designed for reproducibility and easy retraining, with clear evaluation metrics and logging. It delivers faster, consistent, data-backed results and can be extended to related problems with minimal changes.

The project is organized in layers: the data layer prepares and validates inputs through Tokenization module; the modelling layer trains and tunes the model with spaCy / NLTK and Evaluation metrics; and the serving layer exposes predictions via Demo interface. Shared configuration, evaluation, and logging modules support every layer, and the whole pipeline is version-controlled and reproducible. This structure makes the project easy to debug, benchmark, and extend.
