Abstract[English]
Methods and devices are described for detecting code clones in a software program. The source code of the software program is processed into a group of n-gram representations. A clone index is generated for each respective code portion defined in the normalized source code, where each clone index includes a feature vector encoding features of the respective code portion based on the n-gram representations corresponding to the respective code portion. Comparison of the clone indexes is used to detect a code clone, based on matching the feature vectors of the clone indexes.[French]
L'invention concerne des procédés et des dispositifs permettant de détecter des clones de code dans un programme logiciel. Le code source du programme logiciel est traité en un groupe de représentations en n-grammes. Un indice de clone est généré pour chaque partie de code respective définie dans le code source normalisé, chaque indice de clone comprenant un vecteur de caractéristique codant des caractéristiques de la partie de code respective sur la base des représentations en n-grammes correspondant à la partie de code respective. La comparaison des indices de clones est utilisée pour détecter un clone de code, sur la base de l'appariement des vecteurs de caractéristiques des indices de clones.
