Therefore, the theoretical and methodological framework underlying the scientific work carried out within the TiLc-Com Laboratory is based essentially on general linguistics, argumentative and enunciative linguistics, corpus linguistics and automatic language processing, and mainly involves :

• addressing and identifying the complex and general dynamic networks of language, discourse networks and their interaction with knowledge networks (physical, biological, cognitive, etc.), all with the aim of proposing an increasingly automated analysis of the different levels.

• in terms of work methodology :

or compiling different corpora of real discourse, mainly written, with particular attention to the French language, from the 14th to the 21st century, from different fields (science, philosophy, literature, political press and language sciences), typologies (descriptive, narrative, argumentative, expository) and genres (journalistic genres: newspaper article, scientific article, literary genres: novel, short story, etc.);

or carrying out a semantic treatment of the corpus according to the different values to be observed;

or considering the different discourse dynamics on the basis of the linguistic marks that emerge in the discourse (lexical and semantic categories, connectors, operators, tenses, expressions, combinatorics, etc.) ;

or formulating, in different ways , the recurrences, rules, networks and dynamics which underlie, weave and create discourse.

• during and after the analysis process, we will attempt to reinvest the discoveries made in the design and use of computer applications that can be created or optimised for the tasks envisaged, whether scientific or knowledge transfer to other sectors: social, educational, cultural, etc.

• finally, to produce scientific materials and publications, as a tool for disseminating our work, by trying to show successively the linguistic networks and discursive dynamics obtained, which will enable us to reconstruct an increasingly precise system of language, principles of communication and knowledge.
