A tutorial on keyword extraction is located at http://www.nzdl.org/Kea/Download/Kea-5.0-Readme.txt. There you can find details on the internals of KEA, including various parameter settings (e.g., details on vocabularies and supported formats for these).
When controlled vocabularies are used (by default: no), the voc
argument should give the file path to the respective files without
their extensions. When vocformat
is "skos"
, the
extension must be ‘.rdf’; when "text"
, there must be files
with extensions ‘.en’, ‘.rel’ and ‘.use’.
Invisibly returns model
, i.e., the path to the created KEA
model.
