Pro-TEXT Basically, a text is a configuration pertaining to the highest level of linguistic complexity and constituting a communicative unit. But there is still no theoretical model of textualization as a process AND a product, despite the ubiquity and the empirical awareness of texts: in the current state of the art there is no consensual theoretical definition of text, nor are we fully informed on how a text is built, and automatic text-generation approaches have not yet found a satisfactory model. Indeed, texts - and more specifically written texts - are produced under complex constraints among which some were impossible to capture until recently, due to the inaccessibility of insights into the textualization process as such. Real-time recording of the writing process using key-stroke logging provides access to the dynamics of the textualization process. Roughly, written or oral language performances are incremental linearizations constrained by temporality, accompanied by disfluencies due to revision. The Pro-TEXT project aims at • grasping the mechanisms that connect structure, genre constraints and pragmatic aims; • helping to understand the way language unit layouts achieve qualitative leaps; • unveiling the moves that allow a qualitatively new product, the text, to be forged out of available data and structures. Three research teams - Clesthia (linguistics), CeRCA (cognitive psychology) and the LIPN (informatics) will study bursts of writing, which are textual segments produced between two pauses: e.g.: [pause] une cousine qui [pause] peut venir partager du temps avec elle pendant [pause] le [pause] w [pause] eek [pause] – [pause] end. [pause] Four types of writing recorded in real time have been collected: educational reports of child protection, academic essays produced by Master's students, student writings (in French) and short French-English translations. An experimental corpus will complete these data. Linguistic analysis lead by Clesthia aims i) to unearth the linguistic strings chosen by the writers to build up their texts and the links by which they are interconnected; ii) to identify the types of sequences that constitute the linguistic material for textualization, iii) to fix the rules and layout regularities that support their organization in a formally and semantically valid text and the combinatorial strategies used by the writers in various contexts and text genres. Cognitive psychology analysis will interpret the pauses of production and the bursts of writing by identifying the cognitive processes underlying them and how variations in cognitive demands affect these pauses and bursts, as well as the linguistic forms and functions of bursts. Based on machine-learning methodologies (collaborative and dynamical clustering), the Pro-TEXT project will elucidate the dynamics of the textualisation process by modeling relations between temporal indices of cognitive processes and the nature of linguistic forms produced in keylogged writing. Machine-learning incremental approaches will fill a gap in the analysis and representation of real-time language performance, while revealing regularities that remain unremarked under the methodologies used previously. We will offer structured linguistic and psycholinguistic descriptions of textualization processes, multi-layer (linguistically and behaviorally) annotated dynamic corpora, incremental models of the textualization process, and clustering tools adapted to such types of dynamic data.
