Chapter I Semantic Web Take-Off in a European Industry Perspective (2009)

Alain Léger, Johannes Heinecke, Pavel Shvaiko, Jean Charlet, Paola Hobson, François Goasdoué

Semantic Web technology is being increasingly applied in a large spectrum of applications in which domain knowledge is conceptualized and formalized (e.g., by means of an ontology) in order to...

Darwin -— an experimental astronomy mission to search for extrasolar planets (2009)

Cockell, Charles S., Herbst, Tom, Léger, Alain, Absil, O., Beichman, Charles, Benz, Willy, ...

As a response to ESA call for mission concepts for its Cosmic Vision 2015–2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the...

Darwin---an experimental astronomy mission to search for extrasolar planets (2009)

Cockell, Charles S, Herbst, Tom, Léger, Alain, Absil, Olivier, Beichman, Charles, Benz, Willy, ...

As a response to ESA call for mission concepts for its Cosmic Vision 2015--2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the...

Tests of achromatic phase shifters performed on the SYNAPSE test bench: a progress report (2008)

Gabor, Pavel, Schuller, Peter A., Chazelas, Bruno, Decaudin, Michel, Labèque, Alain, Duret, Philippe, ...

The achromatic phase shifter (APS) is a component of the Bracewell nulling interferometer studied in preparation for future space missions (viz. Darwin/TPF-I) focusing on spectroscopic study of...

Semantic difference in ALN (2008)

Alain Léger, Christophe Rey, Farouk Toumani

Abstract. We study the semantic difference operator defined in [16] for ALN. We give a polynomial-time algorithm to compute it. We compare it with the syntactic difference operator defined in [7],...

Stabilising a nulling interferometer using optical path difference dithering (2008)

Gabor, Pavel, Chazelas, Bruno, Brachet, Frank, Ollivier, Marc, Decaudin, Michel, Jacquinod, Sophie, ...

Context. Nulling interferometry has been suggested as the underlying principle for the Darwin and TPF-I exoplanet research missions. Aims. There are constraints both on the mean value of the nulling...

Instrumental stability requirements for exoplanet detection with a nulling interferometer: variability noise as a central issue (2006)

Chazelas, Bruno, Brachet, Frank, Bordé, Pascal, Mennesson, Bertrand, Ollivier, Marc, Absil, Olivier, ...

We revisit the nulling interferometer performances that are needed for direct detection and the spectroscopic analysis of exoplanets, e.g., with the DARWIN [European Space Agency-SCI 12 (2000)] or...

A.: A formal model for semantic web service composition (2006)

Freddy Lécué, Alain Léger

Abstract. Automated composition of Web services or the process of forming new value added Web services is one of the most promising challenges in the semantic Web service research area. Semantics is...

Semantic Web Applications: Fields and Business Cases. The Industry Challenges The Research. (2005)

Léger, Alain, J.B. Nixon, Léger, Shvaiko, Pavel, Charlet, Jean

Semantic Web technology is being increasingly applied in a large spectrum of applications in which domain knowledge is conceptualized and formalized (e.g., by means of an ontology) in order to...

On Identifying Knowledge Processing Requirements (2005)

Léger, Alain, Nixon, Lyndon J.B., Shvaiko, Pavel

The uptake of Semantic Web technology by industry is progressing slowly. One of the problems is that academia is not always aware of the concrete problems that arise in industry. Conversely, industry...

Submitted to Icarus notes version 15 Jan. 04 (2004)

New Family Of, A. Léger, F. Selsis, C. Sotin, T. Guillot, D. Despois, ...

A new family of planets is considered which is in between the rocky terrestrial planets and the gaseous giants, "Ocean-Planets". We present the possible formation, composition and internal...

Ontology domain modeling support for multi-lingual services (2000)

Alain Léger, Géraldine Michel, Peter Barrett, Sylvain Gitton, Asuncion Goméz-pérez, Aarno Lehtola, ...

Abstract. One of the main objectives of a truly user-friendly Information Society is to focus on advanced human language technologies enabling cost-effective interchange across language and culture...
