In the field of textometry, every text analysis software offers its own set of functionalities. Although these functionalities originate in common ideas, their implementations and their names may differ. It is therefore impossible to compile a comprehensive and synthetic list of functionalities straight, or to draw a direct comparison between softwares. This paper sets a structured overview of textometric metafunctionalities. Each of them addresses a type of textual research: text reading and browsing (through different views), listing of units (typically words) with quantitative information, looking at the positions of units in the corpus, paradigmatic and syntagmatic linking of units, texts or properties. This functional typology covers the whole range of textometric processing, from context and parameters initialization to results management and analysis. This typology was elaborated in order to design a new textometric software (project ANR-06-CORP-029). It may also be used to introduce to textometric functionalities, or to characterize software.
