List of online / computer-based annotation tools

Tools (online or PC-based)

Thanks to Hristo Tanev for compiling a preliminary list and emailing the Corpora List.

  • MAE (Multi-purpose Annotation Environment) is an annotation tool created by Amber Stubbs (http://amberstubbs.net) for Brandeis University for use in her dissertation research. It is a lightweight program written in Java, with a MySQLite database back end (SQLiteJDBC driver created by David Crawshaw (http://www.zentus.com/sqlitejdbc/)).

  • CrowdTruth

    The CrowdTruth Framework implements an approach to machine-human computing for collecting annotation data on text, images, sounds and videos.

    • jQuery, Bootstrap, require.js, Python, Jinja, with some CrowdFlower (?!) markup mixed in
  • PyBossa

    PYBOSSA is the ultimate crowdsourcing framework to analyze or enrich data that can't be processed by machines alone.

    • Inspired by Bossa, which is "an open-source software framework for distributed thinking" built with PHP.
