Emergent semantics

In the past, the problem of semantic interoperability in information systems was mostly solved by means of centralization, both at a system and at a logical level. This approach has been successful to a certain extent, but offers limited scalability and fl ...

A Survey of Semantic Based Peer-to-Peer Systems

This paper makes a step in identifying the state of the art in semantic P2P systems. On one hand, lot of research in the P2P systems community has focused on fault-tolerance and scalability, resulting in numberous algorithms, systems such as Chord, Pastry ...

Self-Organizing Schema Mappings in the GridVine Peer Data Management System

Karl Aberer, Philippe Cudré-Mauroux, Parisa Haghani, Adriana Budura

GridVine is a Peer Data Management System based on a decentralized access structure. Built following the principle of data independence, it separates a logical layer -- where data, schemas and mappings are managed -- from a physical layer consisting of a s ...

Scalable peer-to-peer Web search using highly discriminative keys

Vinh Toan Luu

Standard general-purpose Web retrieval relies on centralized search engines that do not realistically scale when applied to the exponentially growing number of documents available on the Web. By taking advantage of the resource sharing principle, Peer-to-P ...

A Peer-to-Peer Architecture for Information Retrieval Across Digital Library Collections

Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Fabius Klemm

Peer-to-peer networks have been identified as promising architectural concepts for developing attractive search scenarios across digital library collections. Digital libraries typically offer sophisticated search over their local content, however, search m ...

The Complex Facets of Reputation and Trust

Karl Aberer, Wojciech Galuba, Zoran Despotovic

Trust and reputation systems have proven to be essential to enforcing cooperative behavior in peer-to-peer networks. We briefly describe the current approaches to building reputation systems: social networks formation, probabilistic estimation and game the ...

Distributed Reputation Systems for Internet-based Peer-to-Peer Systems and Mobile Ad-Hoc Networks

Jean-Yves Le Boudec, Jochen Mundinger, Sonja Buchegger

Reputation systems are widely and successfully used in centralized scenarios. Will they work equally well, however, in decentralized scenarios such as Internet-based peer-to-peer systems and mobile ad hoc networks? ...

Semantic Overlay Networks

Karl Aberer, Philippe Cudré-Mauroux

In a handful of years only, Peer-to-Peer (P2P) systems have become an integral part of the Internet. After a few key successes related to music-sharing (e.g., Napster or Gnutella), they rapidly developed and are nowadays firmly established in various conte ...

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 ...
