Migrating Language Resources from SGML to XML:
The largest effort in the area of standardisation of computer encoding of language resources has been the Text Encoding Initiative (TEI), established in 1987. TEI chose as its underlying standard SGML (Standard Generalized Markup Language), and in the years before the inception of XML, a number of projects encoded their data according to some SGML DTD, TEI compliant, or otherwise. These project...
متن کاملSGML and XML Document Grammars and Exceptions
The Standard Generalized Markup Language (SGML) and the Extensible Markup Language (XML) allow users to de ne document type de nitions (DTDs), which are essentially extended context-free grammars expressed in a notation that is similar to extended Backus{Naur form. The right-hand side of a production, called a content model, is both an extended and a restricted regular expression. The semantics...
متن کاملSuccession in standardization: Grafting XML onto SGML
Succession in standardization is usually a problem. The advantages of improvements are weighed against those of compatibility. If compatibility considerations dominate, a grafting process takes place. This process need not lead to compatibility. According to our taxonomy of successor standards, there are three types of succession (outcomes). Type I, where grafting is achieved, entails compatibi...
متن کاملUne comparaison entre deux méthodes de preuve de sécurité
In this paper, we compare two methods for security proofs a formal method, and the method by reduction from the complexity theory. A modification of the Otway-Rees protocol is proposed to show out a difference between the two methods : the exchanged key is provably secure in the sense of the BAN logic but it is not when we analyze it by reduction. The difference is due to a limitation of BAN lo...
متن کاملUne comparaison de certains indices de pertinence des règles d'association
Résumé. Cet article propose une comparaison graphique de certains indices de pertinence pour évaluer l'intérêt des règles d'association. Nous nous sommes appuyés sur une étude existante pour sélectionner quelques indices auxquels nous avons ajouté l'indice de Jaccard et l'indice d'accords désaccords (IAD). Ces deux derniers nous semblent plus adaptés pour discriminer les règles intéressantes da...
