From Web Data to Entities and Back

Zoltán Miklós, Michele Catasta, Nicolas Bonvin, Julien Gaugaz, Ekaterini Ioannou

We present the Entity Name System (ENS), an enabling infrastructure, which can host descriptions of named entities and provide unique identifiers, on large-scale. In this way, it opens new perspectives to realize entity-oriented, rather than keyword-orient ...

Model-based implementation of real-time applications

Joseph Sifakis

Correct and efficient implementation of general real-time applications remains by far an open problem. A key issue is meeting timing constraints whose satisfaction depends on features of the execution platform, in particular its speed. Existing rigorous im ...

Adaptive actions on shading devices in response to local visual stimuli

Darren Robinson, Frédéric Haldi

Based on 6 years of continuous measurements, we have analysed in detail the occupancy, thermal and visual parameters influencing actions on shading devices in order to derive an accurate model for the prediction of their usage in office buildings. This art ...

Predictive approach for schema evolution

Hassina Bounif

In today's companies and organizations, databases are omnipresent. They are the means to represent and store information. Therefore, they must evolve whenever the information architecture (semantic and structure) changes. Databases are subject to evolution ...

Data-centric trust in ephemeral networks

Maxime Raya

New network types require new security concepts. Surprisingly, trust – the ultimate goal of security – has not evolved as much as other concepts. In particular, the traditional notion of building trust in entities seems inadequate in an ephemeral environme ...

Entity Search with NECESSITY

Zoltán Miklós, Saket Sathe, Gleb Skobeltsyn, Nicolas Bonvin, Ekaterini Ioannou, Anshul Jain

Loosely structured heterogeneous information spaces are typically created by merging data from a variety of different applications and information sources. A common problem these information spaces need to address is that various data describe the same rea ...

idMesh: graph-based disambiguation of linked data

Karl Aberer, Philippe Cudré-Mauroux, Parisa Haghani, Michael Jost

We tackle the problem of disambiguating entities on the Web. We propose a user-driven scheme where graphs of entities -- represented by globally identifiable declarative artifacts -- self-organize in a dynamic and probabilistic manner. Our solution has the ...

Do Microscopic Organisms Feel Turbulent Flows?

Alfred Johny Wüest, Miki Hondzo

Microscopic organisms in aquatic environments are continuously exposed to a variety of physical and chemical conditions. Traditionally, it is accepted that due to their small size the physiology of microscopic organisms is not affected by the moving fluid ...

Evaluating automated parameter constraining procedures of neuron models by experimental and surrogate data

Henry Markram, Felix Schürmann, Sean Lewis Hill, Thomas Berger, Idan Segev

Neuron models, in particular conductance-based compartmental models, often have numerous parameters that cannot be directly determined experimentally and must be constrained by an optimization procedure. A common practice in evaluating the utility of such ...

Conceptual Synopses of Semantics in Social Networks Sharing Structured Data

We are interested in the problem of data sharing in overlay networks that have a social structure, i.e. participants are linked and exchange data with others w.r.t. the similarity of their data semantics. In this paper we propose a methodology to produce c ...
