  KBSET is an environment that provides support for scholarly editing in two
flavors: First, as a practical tool KBSET/Letters that accompanies the
development of editions of correspondences (in particular from the 18th and
19th century), completely from source documents to PDF and HTML presentations.
Second, as a prototypical tool KBSET/NER for experimentally investigating novel
forms of working on editions that are centered around automated named entity
recognition. KBSET can process declarative application-specific markup that is
expressed in LaTeX notation and incorporate large external fact bases that are
typically provided in RDF. KBSET includes specially developed LaTeX styles and
a core system that is written in SWI-Prolog, which is used there in many roles,
utilizing that it realizes the potential of Prolog as a unifying language.
