Sharing of probabilistically correlated data in peer-to-peer networks

Roman Schmidt

The impact of Peer-to-Peer (P2P) networks on the Internet landscape is undisputed. It has led to a series of new applications, e.g., as part of the so-called Web 2.0. The shift from the classical client-server based paradigm of the Internet, with a clear d ...

Emergent semantics

Philippe Cudré-Mauroux

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 ...

From Bioinformatic Web Portals to Semantically Integrated Data Grid Networks

Karl Aberer, Philippe Cudré-Mauroux, Adriana Budura

We propose a semi-automated method for redeploying bioinformatic databases indexed in a Web portal as a decentralized, semantically integrated and service-oriented Data Grid. We generate peer-to-peer schema mappings leveraging on cross-referenced instances ...

Rencontre de la science de l'information géographique et de l'anthropologie culturelle

Abram Pointet

Geographical Information Science and Cultural Anthropology are aimed to collaborate on development projects dedicated to indigenous communities. This fact is first based on a growing intention to integrate the reality and the perception of the development ...

On Optimal Replication Group Splits in P2P Data Stores Based on the Hypercube

P2P data stores excel if availability of inserted data items must be guaranteed. Their inherent mechanisms to counter peer pop- ulation dynamics make them suitable for a wide range of application domains. This paper presents and analyzes the split maintena ...

Semantic validation in spatio-temporal schema integration

Anastasiya Sotnykova

This thesis proposes to address the well-know database integration problem with a new method that combines functionality from database conceptual modeling techniques with functionality from logic-based reasoners. We elaborate on a hybrid - modeling+validat ...

Probabilistic Message Passing in Peer Data Management Systems

Karl Aberer, Philippe Cudré-Mauroux

Until recently, most data integration techniques involved central components, e.g., global schemas, to enable transparent access to heterogeneous databases. Today, however, with the democratization of tools facilitating knowledge elicitation in machine-pro ...

Semantic Integration in MADS Conceptual Model

Stefano Spaccapietra, Anastasiya Sotnykova

Our vision of a viable way for transparent and meaningful processing of heterogeneous spatio-temporal data is to put data semantics in the foundation of an integration process. We present and correlate means of integration as components of the mediation le ...

Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...
