The Copycat Project: An Experiment in Nondeterminism and Creative AnalogiesHofstadter, Douglas 01 January 1984 (has links)
A micro-world is described, in which many analogies involving strikingly different concepts and levels of subtlety can be made. The question "What differentiates the good ones from the bad ones?" is discussed, and then the problem of how to implement a computational model of the human ability to come up with such analogies (and to have a sense for their quality) is considered. A key part of the proposed system, now under development is its dependence on statistically emergent properties of stochastically interacting "codelets" (small pieces of ready-to-run code created by the system, and selected at random to run with probability proportional to heuristically assigned "urgencies"). Another key element is a network of linked concepts of varying levels of "semanticity", in which activation spreads and indirectly controls the urgencies of new codelets. There is pressure in the system toward maximizing the degree of "semanticity" or "intensionality" of descriptions of structures, but many such pressures, often conflicting, must interact with one another, and compromises must be made. The shifting of (1) perceived oundaries inside structures, (2) descriptive concepts chosen to apply to structures, and (3) features perceived as "salient" or not, is called "slippage". What can slip, and how are emergent consequences of the interaction of (1) the temporary ("cytoplasmic") structures involved in the analogy with (2) the permanent ("Platonic") concepts and links in the conceptual proximity network, or "slippability network". The architecture of this system is postulated as a general architecture suitable for dealing not only with fluid analogies, but also with other types of abstract perception and categorization tasks, such as musical perception, scientific theorizing, Bongard problems and others.

De la plausibilitat referencial del llenguatge poètic: Francis Ponge, o el cas d'una poètica referencialistaCapllonch, Begoña 04 February 2010 (has links)
L'objecte d'aquesta tesi ha estat el de defensar, a partir de l'exemple de l'obra de Francis Ponge, la plausibilitat referencial del llenguatge poètic, supòsit tot sovint rebatut a causa d'una radicalització del tòpic de l'autoreferencialitat poètica i per un planteig en suma restringit del concepte de la referencialitat. Però que un poema es constitueixi en tant que específica configuració significant no hauria d'implicar un menyscabament de la seva capacitat de representació, perquè si la poesia és creació mitjançant el llenguatge, tot allò que jutgem poètic no dimanaria sinó de la mateixa idiosincràsia de l'expressió verbal. Així doncs, hem argumentat, en primer lloc, l'efectivitat referencial del llenguatge ordinari per tal d'il·lustrar tot seguit la del poètic i, en particular, la que explicitaria el verb de Francis Ponge, atès que la poètica d'aquest autor es caracteritza, precisament, pel fet d'obstinar-se en una convençuda referencialitat: la que l'impel·lí a dirigir-se envers les coses; la que el dugué a submergir-se en les paraules. El objeto de esta tesis ha sido el de defender, a partir del ejemplo de la obra de Francis Ponge, la plausibilidad referencial del lenguaje poético, supuesto a menudo rebatido a causa de una radicalización del tópico de la autorreferencialidad poética y por un planteamiento en suma restringido del concepto de la referencialidad. Pero que un poema se constituya en tanto que particular configuración significante en modo alguno implicaría un menoscabo de su capacidad de representación, porque si la poesía es creación mediante el lenguaje, todo lo que juzgamos poético no dimanaría sino de la propia idiosincrasia de la expresión verbal. Así pues, hemos argumentado, en primer lugar, la efectividad referencial del lenguaje ordinario para ilustrar a continuación la del poético y, en particular, la que explicitaría el verbo de Francis Ponge, pues la poética de este autor se caracteriza, precisamente, por obstinarse en una convencida referencialidad: la que lo impulsó a dirigirse hacia las cosas; la que lo condujo a sumergirse en las palabras. / Starting from Francis Ponge's work, this PhD thesis argues for the referential plausibility of the poetic language. This assumption has often been contested partly because of the cliché of poetic self-referentiality and partly because the concept of referentiality has had an extremely restricted approach. This thesis suggests that, on the contrary, a poem's capability of becoming a particular and significant configuration does by no means imply a lessening of its representative force. Indeed: if poetry is creation by means of language, everything we judge as poetic stems solely from the idiosyncrasy of verbal expression. Thus, the thesis argues for the referential efficiency of ordinary language to then illustrate the referential efficiency of the poetic. It focuses in particular on the verbum as put forth by Francis Ponge. This author's poetics is best characterized by its persistence in a convinced referentiality, which leads Ponge to address things, and which takes him to sound the depths of words.
