Jun 1, 2025June 2025 — d2cml-ai/Data-Science-Python: Delivered two key updates that boost business value and streamline workflows. Features delivered: FinBERT-based sentiment analysis for financial text and BART-large-CNN-based automatic summarization of PDFs (e.g., rental agreements), enabling faster insights and concise document briefs for analysts. Major maintenance work: repository organization cleanup relocating Contrato_ejercicio.pdf and HW5.ipynb into a new subdirectory 199999_hw5_2025_1 (no functional changes). Impact: improved analyst productivity through NLP capabilities, accelerated data-to-insight cycles, and a cleaner, more maintainable codebase. Technologies/skills demonstrated: FinBERT, BART-large-CNN, Python NLP pipelines, model integration, and repository hygiene.
