Gross's work, and that of the LADL, gives priority to the principles of methodological rigor, respect for data, empirical observation, comprehensive coverage of a language, and reproducibility of experiments. A systematic description of simple sentences of French yielded a dictionary based on the syntax It was for this reason that his methods and results were given the name Lexicon-Grammar. His students have verified this working hypothesis in many typologically diverse languages, including not only Romance languages and German, but also Modern Greek, Korean, Arabic, Local grammars, consisting of finite automata coupled with morpho-syntactic dictionaries, support automatic text analysis Gross described the organization of language as a lexicon-grammar, and argued that any grammar must fail if its formalization fails to take into account its dependence on the lexicon. He demonstrated that to fully describe a language one must collect a huge quantity of tagged word combinations. The facts registered in the dictionaries and grammars resulting from such collection are useful for
natural language processing and in particular for
deep linguistic processing. Gross's students include Alain Guillet, Christian Leclère,
