ACT-DL is being maintained at Bielefeld University Library
as one of the outcomes of the project Automatic Enhancement of
OAI Metadata, which is being funded by the
German Research Foundation (DFG).
How does the Automatic Categorization Work?
The categorization is based on
support vector machines (SVMs).
This is a machine learning model that has been trained using
OAI-DC metadata harvested by
Bielefeld Academic Search Engine (BASE).
