Titel B3 database


The B3 database (B3DB) is a relational database to support corpus studies and computational linguistic project workflows. The database consists of a macro layer to represent process metadata and a micro layer to represent graph-based analyses for querying. The data structures of the micro layer are based on the Linguistic Annotation Framework (LAF), its XML serialization GrAF (ISO 24612:2012) and an extension by Kountz et al. (2008).
