Seventy-five years ago, Walter Benjamin showed us that the line between "production" and "reproduction" had begun to blur. Reproduction was no longer optional, consequential and degrading (the shredding of the original’s aura), but was instead being transformed into a principle of production itself: something was produced bearing in mind how it was to be reproduced. No longer did the original exist (in photography, film, music recordings), but instead diffusion, exhibition. The work existed precisely at the time and place of its enjoyment. Today, the cultural pirates of the new digital era take this principle to the extreme, with a certain characteristic also foreseen by Benjamin: a yearning to participate, to post-produce something captured in order to later return it to the Internet, modified in some way and made available to others. This postproduction is what is now often mixed up with reception, just as production and reproduction used to be in Benjamin’s day. Postproduction on the receiver’s side, which somehow augments and extends the received work, in other words creates an etymologically rigorous author-ization (auctor as the root of both author and augmentation). The cultural pirate only deserves redemption thanks to this creative augmentation.

In recent years, Twitter has become one of the most important microblogging services of the Web 2.0. Among the possible uses it allows, it can be employed for communicating and broadcasting information in real time. The goal of this research is to analyze the task of automatic tweet generation from a text summarization perspective in the context of the journalism genre. To achieve this, different state-of-the-art summarizers are selected and employed for producing multi-lingual tweets in two languages (English and Spanish). A wide experimental framework is proposed, comprising the creation of a new corpus, the generation of the automatic tweets, and their assessment through a quantitative and a qualitative evaluation, where informativeness, indicativeness and interest are key criteria that should be ensured in the proposed context. From the results obtained, it was observed that although the original tweets were considered as model tweets with respect to their informativeness, they were not among the most interesting ones from a human viewpoint. Therefore, relying only on these tweets may not be the ideal way to communicate news through Twitter, especially if a more personalized and catchy way of reporting news wants to be performed. In contrast, we showed that recent text summarization techniques may be more appropriate, reflecting a balance between indicativeness and interest, even if their content was different from the tweets delivered by the news providers.
