14:00, Room N107 (Parc Club) Abstract Tout les jours, de vastes volumes de données sont traités, copiés, et transformés. Le développement et la vérification sémantique de telles transformations de données est, pour l’instant, souvent une tâche manuelle qui ne suit pas une systématique précise. De plus, une transformation de données doit souvent être modifiée au …

Marcos Vaz Salles: A Database Approach to Programming Large-Scale Behavioral Simulations
14:00, Room N107 (Parc Club) Abstract In many scientific domains, researchers are turning to large-scale behavioral simulations to better understand important real-world phenomena. These phenomena emerge as the result of a myriad interactions among large numbers of interdependent agents in a complex system, such as a transportation network or an ecological system. While there has …

Matteo Magnani: Data management with uncertainty
14:00, Room N107 (Parc Club) Abstract The representation of imperfection has always been a major issue in the field of database management. It is in fact well recognized that if we cannot represent imperfection, such as missing, imprecise and uncertain values, we risk to lose much valuable information. Object of the talk will be the …

Gerard de Melo: Large-Scale Data Integration Techniques for Knowledge about Words and Entities
11:00, Room G008 (Parc Club) Abstract An increasing number of applications are making use of explicit knowledge about words and the entities they represent. This talk presents three data integration methods to obtain such knowledge. The first involves learning models to disambiguate word meanings. The second reconciles equivalence and distinctness information about entities from multiple …

Serge Abiteboul et al.: AXART – Enabling Collaborative Work with AXML Artifacts
By Serge Abiteboul, Pierre Bourhis, Alban Galland and Bogdan Marinoiu 15:00, Room N107 (Parc Club) Abstract The workflow models have been essentially operation-centric for many years, ignoring almost completely the data aspects. Recently, a new paradigm of data-centric workflows, called business artifacts, has been introduced by Nigam and Caswell. We follow this approach and propose …

Mauro Sozio: Efficient Distributed Algorithms for Replication in P2P Networks and Large-Scale Information Extraction
14:00, Room N107 (Parc Club) Abstract This talk shall consist of two parts. In the first part, we shall deal with the problem of replicating data items in an unstructured peer-to-peer network. We present a simple distributed greedy algorithm aiming at optimizing the probability of successfully retrieving the requested items. This is the first work …

Armin Roth: Efficient Query Answering in Peer Data Management Systems
13:30, Room N107 (Parc Club) Abstract Peer Data Management Systems (PDMS) consist of a volatile set of peers. Each of them answers queries against its own schema by exploiting both local data and by passing queries to neighboring peers along so-called schema mappings. PDMS are highly flexible due to their decentral nature, but query answering …

Yannis Papakonstantinou: Ajax-based Report Pages as Incrementally Rendered Views
By Yannis Papakonstantinou, UC San Diego Joint work with Yupeng Fu, Keith Kowalczykowski, Kian Win Ong, Kevin Keliang Zhao 14:00, Room G008 (Parc Club) Abstract While Ajax-based programming enables faster performance and higher interface quality over pure server-side programming, it is demanding and error prone as each action that partially updates the page requires custom, ad-hoc …

Wael Khemiri: EdiFlow: data-intensive interactive workflows for visual analytics
14:00, Room N107 (Parc Club) Abstract Visual analytics aims at combining interactive data visualization with data analysis tasks. Given the explosion in volume and complexity of scientific data, e.g. associated to biological or physical processes, social networks etc., visual analytics is called to play an important role in scientific data management. Most visual analytics platforms, …
