Le report des garanties accessoires sur l’obligation de restitution du contrat principal anéanti est une règle du code civil dans sa version issue de l’ordonnance n° 2016-131 du 10 février 2016 portant réforme du droit des contrats, du régime général et de la preuve des obligations. Précisément, la règle est formulée par l’article 1352-9 du code civil : « Les sûretés constituées pour le paiement de l'obligation sont reportées de plein droit sur l'obligation de restituer sans toutefois que la caution soit privée du bénéfice du terme ». Il s’agit de la codification d’une jurisprudence rendue en d’abord en matière de cautionnement, ensuite étendue à l’hypothèque, enfin, par généralisation, à l’ensemble des sûretés, y compris à la solidarité. La portée d’une telle règle est donc générale en droit français. En droit uniforme des affaires issu de l’OHADA, l’Acte uniforme portant organisation des sûretés révisé n’a pas prévu une telle règle. Par contre, le récent projet de texte d’Acte uniforme portant droit général des obligations dans l’espace OHADA prévoit, en s’inspirant de la solution retenue en droit français, d’adopter la règle sous la forme d’une « extension » des garanties accessoires sur l’obligation de restitution du contrat principal anéanti. En effet, l’article 210 alinéa 1 du projet de texte uniforme précité énonce : « Les garanties stipulées pour le paiement de l’obligation primitive sont étendues à l’obligation de restitution ». Les formulations des deux textes, les articles 1352-9 du code civil et 210 alinéa 1 du projet de texte uniforme, sont différentes mais la logique et la politique législative de deux systèmes juridiques convergent. La thèse défendue est que le terme « report » employé par le code civil en son article 1352-9 dans sa version issue de l’ordonnance n° 2016-131 du 10 février 2016 n’existe pas en tant que tel. Le report est en réalité une double substitution ; il y a une substitution d’abord, dans le rapport principal d’obligation et une substitution consécutive dans le rapport de cautionnement. La première substitution qui a lieu concerne le rapport entre le débiteur principal et le créancier. L’anéantissement des effets du contrat principal produit une substitution à l’obligation initiale de source conventionnelle d’une obligation légale fondé sur le quasi-contrat de paiement de l’indu. Cette première substitution conduit à la disparition, par le jeu ou la règle de l’accessoire, de l’obligation initiale de la caution et de son remplacement par une obligation légale nouvelle. Il y a donc une substitution dans le rapport entre le créancier et la caution due à la première substitution. L’obligation légale nouvelle de la caution reprend certains éléments de l’obligation conventionnelle ancienne de celle-ci, tout en étant distincte par d’autres éléments. La base même de l’obligation nouvelle de la caution reste le cautionnement que la caution avait souscrit préalablement. / The postponement of ancillary guarantees on the obligation to return the terminated main contract is a rule of the Civil Code in the version resulting from Order No. 2016-131 of 10 February 2016 related to the reform of contract law of the general regime and the proof of obligations. Specifically, the rule is formulated by article 1352-9 of the Civil Code: "Securities created for the payment of the obligation are automatically transferred under the obligation to return without however depriving the surety of the benefit of the term". It is about the codification of case law handed down first in the field of suretyship, then extended to mortgages, and finally, by generalization, to all securities, including solidarity. The scope of such a rule is therefore general in French law. In the uniform business law of OHADA, the revised Uniform Act on the Organization of Security Interests has not provided for such a rule. On the other hand, the recent draft text of the Uniform Act on the general law of obligations in the OHADA area provides, under the inspiration of the solution adopted in French law, for the adoption of the rule in the form of an "extension" of the accessory guarantees on the obligation to return the terminated main contract. Indeed, Article 210 paragraph 1 of the aforementioned draft uniform text states: "The guarantees stipulated for the payment of the original obligation are extended to the obligation of restitution". The wording of the two texts, Articles 1352-9 of the Civil Code and 210 paragraph 1 of the draft uniform text, are different, but the logic and legislative policy of both legal systems converge. This thesis focuses on the determination of the legal nature of the deferral (or extension) mechanism and its regime. It defends the view that postponement (or extension) is not a technical concept. The deferral is actually a double substitution: a substitution in the main report and a substitution in the bond report.

This thesis deals with one-document summarization of text data. Part of it is devoted to data preparation, mainly to the normalization. Listed are some of the stemming algorithms and it contains also description of lemmatization. The main part is devoted to Luhn"s method for summarization and its extension of use WordNet dictionary. Oswald summarization method is described and applied as well. Designed and implemented application performs automatic generation of abstracts using these methods. A set of experiments where developed, which verified correct functionality of the application and of extension of Luhn"s summarization method too.

[pt] Atualmente os categorizadores de textos construídos por técnicas de aprendizagem de máquina têm alcançado bons resultados, tornando viável a categorização automática de textos. A proposição desse estudo foi a definição de vários modelos direcionados à categorização de pedidos de patente, no idioma português. Para esse ambiente foi proposto um comitê composto de 6 (seis) modelos, onde foram usadas várias técnicas. A base de dados foi constituída de 1157 (hum mil cento e cinquenta e sete) resumos de pedidos de patente, depositados no INPI, por depositantes nacionais, distribuídos em várias categorias. Dentre os vários modelos propostos para a etapa de processamento da categorização de textos, destacamos o desenvolvido para o Método 01, ou seja, o k-Nearest-Neighbor (k-NN), modelo também usado no ambiente de patentes, para o idioma inglês. Para os outros modelos, foram selecionados métodos que não os tradicionais para ambiente de patentes. Para quatro modelos, optou-se por algoritmos, onde as categorias são representadas por vetores centróides. Para um dos modelos, foi explorada a técnica do High Order Bit junto com o algoritmo k- NN, sendo o k todos os documentos de treinamento. Para a etapa de préprocessamento foram implementadas duas técnicas: os algoritmos de stemização de Porter; e o StemmerPortuguese; ambos com modificações do original. Foram também utilizados na etapa do pré-processamento: a retirada de stopwords; e o tratamento dos termos compostos. Para a etapa de indexação foi utilizada principalmente a técnica de pesagem dos termos intitulada: frequência de termos modificada versus frequência de documentos inversa TF -IDF . Para as medidas de similaridade ou medidas de distância destacamos: cosseno; Jaccard; DICE; Medida de Similaridade; HOB. Para a obtenção dos resultados foram usadas as técnicas de predição da relevância e do rank. Dos métodos implementados nesse trabalho, destacamos o k-NN tradicional, o qual apresentou bons resultados embora demande muito tempo computacional. / [en] Nowadays, the text s categorizers constructed based on learning techniques, had obtained good results and the automatic text categorization became viable. The purpose of this study was the definition of various models directed to text categorization of patent s application in Portuguese language. For this environment was proposed a committee composed of 6 (six) models, where were used various techniques. The text base was constituted of 1157 (one thousand one hundred fifty seven) abstracts of patent s applications, deposited in INPI, by national applicants, distributed in various categories. Among the various models proposed for the step of text categorization s processing, we emphasized the one devellopped for the 01 Method, the k-Nearest-Neighbor (k-NN), model also used in the English language patent s categorization environment. For the others models were selected methods, that are not traditional in the English language patent s environment. For four models, there were chosen for the algorithms, centroid vectors representing the categories. For one of the models, was explored the High Order Bit technique together with the k-NN algorithm, being the k all the training documents. For the pre-processing step, there were implemented two techniques: the Porter s stemization algorithm; and the StemmerPortuguese algorithm; both with modifications of the original. There were also used in the pre-processing step: the removal of the stopwards; and the treatment of the compound terms. For the indexing step there was used specially the modified documents term frequency versus documents term inverse frequency TF-IDF . For the similarity or distance measures there were used: cosine; Jaccard; DICE; Similarity Measure; HOB. For the results, there were used the relevance and the rank technique. Among the methods implemented in this work it was emphasized the traditional k-NN, which had obtained good results, although demands much computational time.
