I have, unfortunately, been unable to use Gephi. I've uninstalled and reinstalled various versions of the beta - 7 and 8 - and it refuses to work. I hate to blame technology for something I could fix myself if I were more tech-savvy, but I'm pretty sure it keeps messing up because my computer runs on Vista.
That being said, I would like to discuss the idea of Gephi.
Gephi takes the vast world of literary analysis and compacts it into a tiny little nebula of information. Trends are turned into tiny planets and stars in the nebula that Gephi creates from each piece of work it reads. It takes information and data that would otherwise take hours to accrue, and consolidates them into easily-viewed "nodes" on its web graph. Looking at the graph itself is... different.
Personally, I have never studied literature in such a mathematical fashion, and, I'm going to be frank, it's weird to me. However, I do think it's necessary with the endlessly expanding universe of literature and knowledge. Without programs like Gephi, knowledge and information disappear into the abyss. As humbling a realization this is, it is impossible for humans to capture, analyze, and use every bit of knowledge we come across. As The Library of Babel and the literary philosophy of Derrida's Mal d'Archive posit, an archive has a "death drive". Constantly expanding to the point of disappearing into the margins, the vast and expanding oeuvre of mankind does not want to be known.
While I generally roll my eyes at people who think machines will supersede mankind, it is when I see programs like Gephi that I can sympathize a little with that paranoia. Humans just aren't good enough anymore. We create at a faster rate than we can analyze and archive, and efforts to become more efficient are made in vain. Gephi can gather up and read information, then preserve it in cryogenic stasis for man to further explore.
