Abstract

Un procédé pour détecter et localiser lapparition dans un flux de données de toute chaîne complexe appartenant à un dictionnaire complexe prédéfini est décrit. Une chaîne complexe peut comprendre un nombre arbitraire de chaînes cohérentes entrelacées et de chaînes ambiguës. Le procédé comprend un premier processus visant à transformer le dictionnaire complexe en une structure simple pour permettre de mener continuellement une recherche efficace sur le plan des calculs et un deuxième processus pour examiner les données reçues en temps réel à laide de la structure simple. Le procédé peut être accompli par un article manufacturé comprenant au moins un support lisible par processeur et des instructions figurant sur le au moins un support. Les instructions amènent un processeur à apparier les données examinées à une chaîne complexe d'objets appartenant au dictionnaire complexe, le processus d'appariement étant fondé sur l'égalité à des chaînes cohérentes constituantes et sur la congruence à des chaînes ambiguës, de la chaîne complexe de l'objet.
