The French Digital Council was given a mandate to examine the question of Net Neutrality in terms of the effectiveness of current legal provisions with a view to protecting the freedom of expression of Internet users. The Council is of the opinion: That French legislation does not sufficiently protect freedom of expression in view of the development of content filtering, blocking, censorship and slowing practices. That the principle of neutrality should be recognised as a fundamental principle necessary for the freedom of communication and the freedom of expression and written into the law at the highest level of the hierarchy of norms: - Into the title of the 1986 Act, renamed “Freedom of Expression and Communication Act” rather than solely “Freedom of Communication Act”; - Into the second paragraph of the first article of the 1986 Act, to read, “The neutrality of communication networks, infrastructures and access and communication services open to the public by means of electronic channels shall guarantee access to information and means of expression on a non-discriminatory, equitable and transparent basis.” That the principle of neutrality should supplement and clarify the existing legislative provisions: - As a fundamental freedom, its enforcement is to be directly under the control of the courts. Any restriction may only be made by common law and in compliance with rule of law procedures. - Through the freedom of communication and expression, the principle of neutrality asserts the freedom of creation and innovation and contributes to digital citizenship. Its implementation should constantly keep pace with technological innovations, economic change and developments in uses, especially with regard to mobile technology, peer-to-peer communications and connected objects. It is for the executive and the legislature to establish a method of governance and a timeframe, if deemed necessary. That, lastly, to ensure the effective, enduring implementation of this principle, indicators should be set up to measure the level of neutrality of networks and services open to the public, in liaison with the political, economic and social stakeholders and the regulatory authorities, including at European level.

Depuis maintenant des milliers d'années, nous collectons de l'information (recensements...) et utilisons des algorithmes (en cuisine, notamment !). Mais récemment, la récolte a littéralement explosé : les technologies numériques nous permettent de créer, de stocker et de transformer l'information. Ordinateurs personnels, professionnels, objets connectés, réseaux sociaux... Chacun de nous contribue activement, et quotidiennement, à façonner un nouveau continent : la terra data. Faut- il uniquement en avoir peur ? Quels sont les risques ? Point de fatalisme ! Cet ouvrage nous invite à agir pour une utilisation des données plus responsable et humaniste : le numérique n'est pas réservé aux experts, c'est un sujet de société. Utilisateurs, associations, ingénieurs, entreprises, enseignants : la mobilisation de tous est requise. Un numérique démocratique et solidaire est possible, à nous de nous en emparer !

Qu'allons-nous faire des données numériques ?

This volume was primarily intended to present selected papers from the workshop on Theory and Applications of Nested Relations and Complex Objects, held in Darmstadt, FRG, from April 6-8, 1987. Other papers were solicited in order to provide a picture of the field as general as possible. Research on nested relations and complex objects originates in the late seventies. The motivation was to obtain data models and systems which would provide support for so-called complex objects or molecular structures, i.e., for hierarchically organized data, thereby overcoming severe shortcomings of the relational model. This theme of research is now maturing. Systems based on those ideas are beginning to be available. Languages of various natures (algebras, calculi, graphical, logic-oriented) have been designed and a theory is slowly emerging. Finally, new developments in database technology and research are incorporating features of models involving complex objects. A variety of approaches is represented in this volume. The first three papers give overviews of major pioneering implementation efforts. The fourth paper is devoted to the important issue of implementation of storage structures. The next three papers propose excursions in the foundations of nested relations and complex objects. The following six contributions are all devoted to modeling of complex objects. The area of database design is represented by the last four papers.

This book constitutes the thoroughly refereed post-conference proceedings of the First International Workshop on Personal Analytics and Privacy, PAP 2017, held in Skopje, Macedonia, in September 2017. The 14 papers presented together with 2 invited talks in this volume were carefully reviewed and selected for inclusion in this book and handle topics such as personal analytics, personal data mining and privacy in the context where real individual data are used for developing a data-driven service, for realizing a social study aimed at understanding nowadays society, and for publication purposes.

Personal Analytics and Privacy. An Individual and Collective Perspective

Gilles Dowek

Algorithms are probably the most sophisticated tools that people have had at their disposal since the beginnings of human history. They have transformed science, industry, society. They upset the concepts of work, property, government, private life, even humanity. Going easily from one extreme to the other, we rejoice that they make life easier for us, but fear that they will enslave us. To get beyond this vision of good vs evil, this book takes a new look at our time, the age of algorithms. Creations of the human spirit, algorithms are what we made them. And they will be what we want them to be: it's up to us to choose the world we want to live in.

The Age of Algorithms

This product is a complete reference to both classical material and advanced topics that are otherwise scattered in sometimes hard-to-find papers. A major effort in writing the book was made to highlight the intuitions behind the theoretical development.

Algorithms will be what we want them to be: we must choose the world we want to live in.
