ACT-DL logo

The automatic classification toolbox for Digital Libraries (ACT-DL) provides tools for automatic text categorization according to standard library classifications using machine learning-based text categorizers. ACT-DL has been developed during the DFG-funded project Automatic Enhancement of OAI Metadata. The currently supported reference classification system is the Dewey Decimal Classification (DDC).
