Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In the web context, it is difficult to disentangle presentation from process logic, and sometimes even data is not separate from the presentation. Consequently, it becomes crucial to define an abstract model for business processes, and their mapping into a ...
In mobile teamwork environments two basic problems exist: how to discover someone based on a profile (skills, reputations) and how to assess that person’s “credibility” (trust). A lot of work has been done on the issues of collecting and ...
The P-Grid approach enables distributed search and replication. Gridella, a P2P system based on P-Grid, improves on Gnutella’s search performance while reducing bandwidth requirements. Fu ...
Peer-To-Peer systems are driving a major paradigm shift in the era of genuinely distributed computing. Gnutella is a good example of a Peer-To-Peer success story: a rather simple software enables Internet users to freely exchange files, such as MP3 music f ...
Managing trust is a problem of particular importance in peer-to-peer environments as one encounters frequently unknown agents. Existing methods for trust management based on reputation do however not scale as they rely on some form of central database or g ...

Automatizing information commerce requires languages to represent the typical information commerce processes. Existing languages and standards cover either only very specific types of business models or are too general to capture in a concise way the speci ...
To find a configuration of a distributed system satisfying performance goals is a complex search problem that involves many design parameters, like hardware selection, job distribution and process configuration. Performance models are a powerful tools to a ...
This paper describes our Gnutella compatible P2P system Gridella which is based on the P-Grid approach. P-Grid has several advantages over the standard Gnutella infrastructure, for example, that probabilistic estimates can be given for successful search re ...
