Global index of the decay of the aura of language, the Dadameter aims at measuring our distance to Dada. It was inspired by the work of the french writer Raymond Roussel. The project is a satire about the recent transmutation of language into a global market ruled by Google et al. and uses the most up-to-date technologies of control to draw cartographies of language at large scale. Imagine a world of transparency where all desires are negotiated on a global market and their risks are evaluated and optimized. The Dadameter is a tool for the profiling of language at large scale and the historical tracking of artistic and literary movements. It brings about a new alliance between art, science and global finance. We use up-to-date 2.0 trend analysis and data visualization technologies, neural networks, graph theory or quantitative structural linguistics in order to be able to predict the next artistic craze.
