It is designed on the base of TEX and PostScript using the Dvips interface, and includes a set of Maya fonts. The ancient Maya’s writing system is very particular: base writing signs attach each other from all four sides (left, right, top, bottom), being aslo rotated and rescaled and could not be produced with usual TEX’s tools. For example, we type: \maya{li.AM2 u.TUN/CHU uj.UJ.ki death.KIMI/la} to ', $. %+ (& " -(Dresden codex) .

We applied to the Dresden Codex, one of the only three manuscripts that reached us, encoded for L A T E X with the mayaT E X package, our graded representation method of hybrid non-supervised learning, intermediate between clustering and oblique factor analysis, and following Hellinger metrics, in order to obtain a nuanced image of themes dealt with: the statistical entities are the 214 codex segments, and their attributes are the 1687 extracted bigrams of signs. For comparison, we introduced in this approach an exogenous element, i.e. the splitting of the composed signs into their elements, for a finer elicitation of the contents. The results are visualized as a set of "thematic concordances": for each homogeneous semantic context, the most salient bigrams or sequences of bigrams are displayed in their textual environment, which sheds a new light on the meaning of some little understood glyphs, placing them in clearly understandable contexts.

Nous avons appliqué au codex de Dresde, l'un des trois seuls manuscrits qui nous soient parvenus, codé sous L A T E X avec le système mayaT E X, notre méthode de représentation graduée, par apprentissage non supervisé hybride entre clustering et analyse factorielle oblique, sous la métrique de Hellinger, afin d'obtenir une image nuancée des thèmes traités : les individus statistiques sont les 212 segments de folio du codex, et leurs attributs sont les 1687 bigrammes de signes extraits. Pour comparaison, nous avons introduit dans cette approche endogène un élément exogène, la décomposition en éléments des signes composites, pour préciser plus finement les contenus. La rétro-visualisation dans le texte original des résultats et expressions dégagées éclaire la signification de certains glyphes peu compris, en les situant dans des contextes clairement interprétables.

It is designed on the base of TeX and PostScript using the Dvips interface, and includes a set of Maya fonts. The ancient Mayan writing system is very particular: base writing signs attach to each other from all four sides (left, right, top, bottom), and are also rotated and rescaled.
