Les màquines del futur pensaran i sentiran

Aquest any, la revista International Journal of Synthetic Emotions, líder internacional en l'estudi de les emocions artificials, ha editat dos números especials dedicats a la reflexió sobre emocions, cognició i computació, en honor a Alan Turing, el creador de la intel·ligència artificial i de les computadores i l'expert que va fer possible desxifrar els codis de la màquina Enigma. Hi han contribuït teòrics de la computació, programadors de conversadors artificials i enginyers que treballen per dissenyar màquines més eficients que segueixen estructures cognitives bioinspirades.Este año, la revista International Journal of Synthetic Emotions, líder internacional en el estudio de las emociones artificiales, ha editado dos números especiales dedicados a la reflexión sobre emociones, cognición y computación, en honor a Alan Turing, el creador de la inteligencia artificial y de las computadoras y el experto que hizo posible descifrar los códigos de la máquina Enigma.

Turing e a Enigma

Neste artigo, depois de fazer uma descrição da máquina crip-tográfica Enigma usada pelas tropas alemãs na segunda guerra mundial,apresenta-se alguma da história sua criptanálise, que envolve ideias atribuí-das a Alan Turing

Abstract Body, Abstract Machine: Alan Turing's Drama of Difference

In order to prove that mathematics cannot be exhausted by a finite set of procedures, Alan Turing conceives, in 1936, of an abstract machine 1. The machine makes its debut in “On Computable Numbers with an application to the Entscheidungsproblem,” his first major mathematical paper 2. A close reading of this machine’s dynamic will show that Turing’s thought in the field of mathematics is a consciously embodied thought that contemplates its own incompleteness. By examining Turing’s machine through the lens of incompleteness, this project will reveal how, through his extension into abstraction, Turing engages in a paradoxically intensive movement that reveals his body as inextricably enfolded in thought. To understand this radical act of contemplation, Turing must be situated within a history of thinkers working against totality, because in thinking his own incompleteness, he refutes the idea that systems are defined by completeness, or that the unfolding of something is circumscribed by that something as goal. This constellation of thinkers includes Kurt Gödel, before Turing, with his Incompleteness Theorem 3; it also includes Gilles Deleuze, with his explanation of how meaning gets made in The Logic of Sense ,4 and Michel Foucault, with his formulation of meaning’s dissolution in “The Thought of the Outside.”5 Brian Massumi then ushers this tradition into the present by defining the limit of a human being as immanent to that being in Parables for the Virtual.6 Massumi grounds his theory in Deleuzeian and Foucauldian concepts, themselves built from Turing’s legacy of lived thought, which in turn is grounded in Gödel’s theorem. Explaining these writers’ relation to Turing’s work on incompleteness will reveal the way in which systems of meaning are always torn between their own constitution and dissolution; this state of being torn will clarify, in turn, the movement of Turing’s mathematical body

Bletchley Park text: using mobile and semantic web technologies to support the post-visit use of online museum resources

A number of technologies have been developed to support the museum visitor, with the aim of making their visit more educationally rewarding and/or entertaining. Examples include PDA-based personalized tour guides and virtual reality representations of cultural objects or scenes. Rather than supporting the actual visit, we decided to employ technology to support the post-visitor, that is, encourage follow-up activities among recent visitors to a museum. This allowed us to use the technology in a way that would not detract from the existing curated experience and allow the museum to provide access to additional heritage resources that cannot be presented during the physical visit. Within our application, called Bletchley Park Text, visitors express their interests by sending text (SMS) messages containing suggested keywords using their own mobile phone. The semantic description of the archive of resources is then used to retrieve and organize a collection of content into a personalized web site for use when they get home. Organization of the collection occurs both bottom-up from the semantic description of each item in the collection, and also top-down according to a formal representation of the overall museum story. In designing the interface we aimed to support exploration across the content archive rather than just the search and retrieval of specific resources. The service was developed for the Bletchley Park museum and has since been launched for use by all visitors
