Computer Analysis Reveals the Stunning Complexity of the Star Wars Expanded Universe

The Star Wars expanded universe is huge. Really huge. Like, you just won't believe how vastly, hugely, mind-bogglingly huge it really is. To grasp the full extent of this hugeness, a team of data scientists used a new computer program to analyse it, revealing some unexpected things about the extended saga. A research team from Switzerland's École Polytechnique Fédérale de Lausanne used a new computer program to analyse hundreds of web pages devoted to the Expanded Star Wars Universe, primarily via Wookieepedia. Then, to make sense of all this data, the researchers applied a bit of graph theory and some maths; this allowed the researchers to get a handle on all the characters, communities and timelines involved in the story, and how everything fits together. The project was led by French data scientist and Star Wars enthusiast Kirell Benzi and assisted by Pierre Vandergheynst of EPFL's Signal Processing Laboratory 2.

No doubt, one of the more remarkable things about Star Wars is the way it lends itself to universe building. In addition to the seven full-length feature films, the saga has grown in other ways, including through numerous books, television series, video games and other creative outlets. Here's what the researchers learned when they put it all together.

The Expanded Star Wars Universe consists of a whopping 21,647 characters. That number drops to 19,612 if every character listed as "unidentified" is removed. Of these, an astounding 7563 play an important role. Among those drawn to the ways of the Force, 1367 are Jedi and 724 are Sith. These characters are dispersed among 640 distinct communities on 294 planets. Surprisingly, 78 per cent of the galaxy's population is human.

That's a lot of humans. Note: This graph does not include every species.

Not content to stop there, Benzi and Vandergheynst also placed each character within the timeline of the story. Star Wars takes place over the course of 36,000 years, which is broken down into six main periods: before the Republic, the Old Republic, the Empire, the Rebellion, the New Republic and the Jedi Order. Analysis shows that Star Wars characters aren't evenly distributed throughout the length of the story.

"We see that the most popular eras are from the films: Rise of the Empire and the Rebellion era," Benzi explained on his blog. "The Old Republic era is also popular (despite having fewer people) thanks to the MMORPG (video game) Star Wars: The Old Republic." The extra colours on the chart above highlight characters living in different eras. Darth Vader, for example, makes an appearance in both Rise of the Empire and in the Rebellion era.

This visualisation shows how communities of characters interact together.

"As you can see the whole Star Wars universe is coherent and fun details can be revealed using graph theory," noted Benzi at his blog. "However let's not forget that we need data to do data-science. In our case, wiki contributors are of paramount importance as they actually create the content we use to blog about. May the Force be with them, always."

The orange-red nodes are from Rise of the Empire Era (episodes 1-3), the blue nodes represent the Rebellion era (episodes 4-6), and the green ones represent both eras. Black nodes represent missing data. On the right, black nodes have been replaced by the best compromise using their neighbours.

Benzi's team also mapped the most connected characters in the Star Wars Universe. Not surprisingly, Anakin Skywalker tops the list. Super interesting to see Boba Fett at number 10; that bounty hunter clearly gets around. And check out Revan, a character from the Old Republic Era, who makes an appearance in the 13th slot.

"To put some order into this massive forest of data, we based our approach on network analysis. In other words, all the connections that one character has with all the others," noted LTS2 researcher Xavier Bresson in a press statement. "Using these cross-references, we are able to accurately determine the time period of the character almost without fail, when this information is not directly provided in the books or movies."

This entire project may seem indulgent, but this data-parsing technique could be applied elsewhere. As Benzi explained, this "program maps out connections in the mass of unorganized data available on the net". These algorithms can not just extract data according to precise criteria, they can also create links among data points, do sorting, quantification, interpretation and seek out missing information. In future, a program like this could be used to perform historical and sociological research, along with other scientific research interests.

    Anyone else completely bored of Star Wars and hoping for something new to be created on a shoe string with substance and creativity? Just sayin'

      Reading and commenting contradicts your statement, does someone need a hug?

      Plenty out there if you're bothered to look but I suppose its easier just to complain about what other people enjoy.

      One of the top creative consultants - DEMC, I think lent some material for episodde VII, VIII etc. He's coming up with a better, non PC leftist, SCI FI project.

        I'm fascinated. Please describe how Star Wars is "PC leftist" science fiction.

    Loved the hitchhikers guide reference at the start :) you needed to finish it off with
    "I mean you may think it's a long walk down the road to the chemist, but that's just peanuts to the universe"

    Didn't Disney officially declare pretty much all of the expanded universe non cannon though?
