  The multilingual dictionary of noun valency Portlex is considered to be the
trigger for the creation of the automatic language generators Xera and
Combinatoria, whose development and use is presented in this paper. Both
prototypes are used for the automatic generation of nominal phrases with their
mono- and bi-argumental valence slots, which could be used, among others, as
dictionary examples or as integrated components of future autonomous
E-Learning-Tools. As samples for new types of automatic valency dictionaries
including user interaction, we consider the language generators as we know them
today. In the specific methodological procedure for the development of the
language generators, the syntactic-semantic description of the noun slots turns
out to be the main focus from a syntagmatic and paradigmatic point of view.
Along with factors such as representativeness, grammatical correctness,
semantic coherence, frequency and the variety of lexical candidates, as well as
semantic classes and argument structures, which are fixed components of both
resources, a concept of a multi-sided prototype stands out. The combined
application of this prototype concept as well as of word embeddings together
with techniques from the field of automatic natural language processing and
generation (NLP and NLG) opens up a new way for the future development of
automatically generated plurilingual valency dictionaries. All things
considered, the paper depicts the language generators both from the point of
view of their development as well as from that of the users. The focus lies on
the role of the prototype concept within the development of the resources.
