Quand Google Books permet de comprendre notre génome culturel Pour une fois, on va dire du bien de Google dans cette lecture de la semaine. A travers un article paru sur le site de Discover Magazine en décembre 2010, sous la plume de Ed Young. Le titre de cet article : “Le génome culturel ; Google Books révèle les traces de la notoriété, de la censure et des changements de la langue”. “De la même manière qu’un fossile nous dit des choses sur l’évolution de la vie sur terre, explique Ed Young, les mots inscrits dans les livres racontent l’histoire de l’humanité. Heureusement, poursuit Young, c’est exactement ce que fait Google depuis 2004 avec Google Books. 15 millions de livres ont été numérisés aujourd’hui, soit 12 % de l’ensemble des livres qui ont été publiés à ce jour.

Culturomics research uses quarter-century of media coverage to forecast human behavior "Culturomics" is an emerging field of study into human culture that relies on the collection and analysis of large amounts of data. A previous culturomic research effort used Google's culturomic tool to examine a dataset made up of the text of about 5.2 million books to quantify cultural trends across seven languages and three centuries. Now a new research project has used a supercomputer to examine a dataset made up of a quarter-century of worldwide news coverage to forecast and visualize human behavior. Using the tone and location of news coverage, the research was able to retroactively predict the recent Arab Spring and successfully estimate the final location of Osama Bin Laden to within 200 km (124 miles). Tone Leetaru says that examining the tone of a news story is one of the most important aspects of his version of culturomics and the most reliable metric for conflict.

In 500 Billion Words, a New Window on Culture The digital storehouse, which comprises words and short phrases as well as a year-by-year count of how often they appear, represents the first time a data set of this magnitude and searching tools are at the disposal of Ph.D.’s, middle school students and anyone else who likes to spend time in front of a small screen. It consists of the 500 billion words contained in books published between 1500 and 2008 in English, French, Spanish, German, Chinese and Russian. The intended audience is scholarly, but a simple online tool allows anyone with a computer to plug in a string of up to five words and see a graph that charts the phrase’s use over time — a diversion that can quickly become as addictive as the habit-forming game Angry Birds. With a click you can see that “women,” in comparison with “men,” is rarely mentioned until the early 1970s, when feminism gained a foothold. The lines eventually cross paths about 1986. The data set can be downloaded, and users can build their own search tools.
