  The search for linguistic patterns, stylometry and forensic linguistics have
in the theory of complex networks, their structures and associated mathematical
tools, allies with which to model and analyze texts. In this paper we present a
new model supported by several mathematical structures such as the hypergraphs
or the concept of derivative graph to introduce a new methodology able to
analyze the mesoscopic relationships between sentences, paragraphs, chapters
and texts, focusing not only in a quantitative index but also in a new
mathematical structure that will be of singular help to both: detecting the
style of an author and determining the language level of a text. In addition,
these new mathematical structures may be useful to detect similarity and
dissimilarity in texts and, eventually, even plagiarism.
