Open-Source Document Mining

Overview is a document mining application originally built for investigative journalists. It’s also used for legal work, training machine learning models, and research of all types. It’s a visualization and analysis tool designed for sets of documents, from dozens to millions of pages of material.

Overview imports many formats and languages, includes built-in OCR, a sophisticated search engine, document annotationword clouds, entity detection, and topic-based document clustering. It has tagging and metadata support and supports many input and export formats. If you need custom analysis, you can write your own plugins using the API.
