A crowdsourcing framework to analyze or enrich data that can't be processed by machines alone

Pybossa is a free, open-source, crowd-sourcing and micro-tasking platform. It enables users to create and run projects that utilise online assistance in performing tasks that require human cognition such as image classification, transcription, geocoding and more.

PyBossa can help researchers, civic hackers and developers to create projects where anyone around the world with some time, interest and an internet connection can contribute. It was inspired by the BOSSA crowdsourcing engine but is written in Python and it is published under the GNU Affero GPL v3.0 License. A demo of PyBossa can be found here.

  • MicroPasts – British Museum and University College of London

Thee British Museum and the University College of London have built a PyBossa-powered platform that invites members of the public to become citizen archeologists. The Micropasts project aims to create the world’s leading prehistoric metal database and change the way we research our collective past. It seeks contributions to help create 3D models of some of the British Museum’s vast collection of Bronze Age artefacts using a process known as photomasking, and to transcribe their associated paper records and identify their sites of discovery.The Micropasts team have created over 100 archival transcription, geo-referencing and photomasking projects, and is at the forefront of crowdsourcing humanitarian research.

The British Library has created LibCrowds, a crowdsourcing project for transcribing library records. LibCrowds’ maiden project – Convert-a-Card – uses PyBossa technology to ask volunteers to transcribe text from printed card catalogues into electronic records, making them available to a worldwide audience. The project is initially focused on the library’s Asian and African collections. Data identified, transcribed or translated as part of the project will be freely accessible from the British Library’s Explore catalogue.

The National Library of Israel has constructed a new platform using PyBossa software with the aim of improving their metadata. They ask contributors to tag, transcribe and answer questions relating to historical Israeli documents.
