Graph Chatbot

Chattez avec Graph Search

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.

Building trust-aware P2P systems

Zoran Despotovic

This thesis is concerned with enabling e-commerce applications in decentralized environments, P2P networks in particular. The work goes along the following two dimensions: P2P reputation systems design and building P2P e-commerce services and applications. ...

Towards a Foundation Model for Peer-to-Peer Web Information

Karl Aberer, Jie Wu

We find that there lacks a formal algebraic framework in the research area of P2P information retrieval. Such a formal framework is indispensable and pivotal. On the one hand, no solid theoretical foundation can explain why the results of many ad-hoc comme ...

On de Bruijn Routing in Distributed Hash Tables: There and Back Again

Karl Aberer, Anwitaman Datta, Sarunas Girdzijauskas

We show in this paper that de Bruijn networks, despite providing efficient search while using constant routing table size, as well as simplicity of the understanding and implementation of such networks, are unsuitable where key distribution will be uneven, ...

Beyond "Web of Trust": Enabling P2P E-commerce

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

The huge success of eBay has proven the demand for customer-to-customer (C2C) electronic commerce. eBay is a centralized infrastructure with all its scalability problems (network bandwidth, server load, availability, etc.). In this paper we argue that C2C ...

Lazy Parameter Passing

Patrick Eugster

Peer-to-peer (P2P) systems are strongly decentralized and asynchronous distributed settings involving a potentially large number of hosts. A common programing model for P2P infrastructures is that of a distributed hashtable (DHT), though which peers share ...

Updates in Highly Unreliable, Replicated Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

In this paper we study the problem of updates in truly decentralised and self-organising systems such as pure P2P systems. We assume low online probabilities of the peers (

Scalable Data Access in Peer-to-Peer Systems Using Unbalanced Search Trees

Karl Aberer

With the appearance of Peer-to-Peer information systems the interest in scalable and decentralized data access structures is attracting increasingly interest. We propose to that end P-Grid, a scalable data access structure resulting from the distribution o ...

Efficient Search in Unbalanced, Randomized Peer-To-Peer Search Trees

Karl Aberer

Scalable mechanisms to support efficient key-based search in distributed systems are an important part of the infrastructure of peer-to-peer systems and global information systems. They received substantial attention both in information and communication s ...

A Decentralized Architecture for Adaptive Media Dissemination

Karl Aberer, Philippe Cudré-Mauroux

P2P content distribution networks have become extremely popular on the Internet. Due to their self-organization properties, they suffer from the lack of control to balance the load among peers for contents of different popularity. In this paper, we define ...

Improving Data Access in P2P Systems

Karl Aberer, Manfred Hauswirth, Roman Schmidt

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 ...
