zpdf is a high-performance PDF text extraction library written in Zig that focuses on speed, low overhead, and modern parsing techniques. It leans heavily on memory-mapped file reading and zero-copy patterns where possible, so it can scan large PDFs without repeatedly copying data around in memory. The library supports streaming extraction using efficient arena allocation, making it well suited for workloads that need to process big documents quickly or in batches. ...

LangExtract is a Python library developed by Google that leverages large language models (LLMs) to extract structured information from unstructured text—such as clinical notes, research papers, or literary works—based on user-defined instructions. It is designed to transform free-form text into reliable, schema-constrained data while maintaining traceability back to the source material. Each extracted entity is precisely grounded in its original context, allowing visual inspection and validation via automatically generated interactive HTML visualizations. ...

Blind Watermark is a Python library for embedding hidden information inside images and recovering it without the original source image. It uses a DWT-DCT-SVD signal-processing pipeline to place watermarks with minimal visible change. Watermarks can contain text or raw bit arrays and may be protected with separate image and watermark passwords. The package provides both a Python API and command-line interface for embedding and extraction. Its examples evaluate recovery after rotation, cropping, masking, resizing, noise, cuts, and brightness changes. Multiprocessing can use several CPU cores during processing. ...

...The project is intended as a research reference for event extraction, knowledge modeling, forecasting, and language-resource development.

aeneas is a Python/C library and a set of tools to automagically synchronize audio and text (aka forced alignment). aeneas automatically generates a synchronization map between a list of text fragments and an audio file containing the narration of the text. In computer science this task is known as (automatically computing a) forced alignment.

Simple, Pythonic, text processing, Sentiment analysis, part-of-speech tagging, noun phrase extraction, translation, and more. It provides a simple API for diving into common natural language processing (NLP) tasks such as part-of-speech tagging, noun phrase extraction, sentiment analysis, classification, translation, and more. TextBlob stands on the giant shoulders of NLTK and pattern, and plays nicely with both.
