Our Nerdiest Contest Yet
These past few years, my life has been a little crazy. Besides working at Mirrix full-time, I have been attending graduate school. In a few short weeks (assuming everything goes as planned), I will be done with my Masters in Digital Media Communication from the University of Washington. I’m pretty excited to have my evenings and weekends back and return to the world of reading novels instead of textbooks.
That said, I do love school and all I’ve learned.
Right now I am taking a class on networks. When I first saw the textbook, which was over 700 pages long and chocked-full of math equations, I wished I had chosen a different class. Now that we are nearing the end of the quarter, though, I am excited to put some of my new-found knowledge into practice. I want to start with what will certainly be Mirrix’s nerdiest contest yet. Are you ready?
Eigenvector Centrality is a measure in graph theory that can help to determine influence in a network. It basically shows how important a vertex (a point on the graph) is, based on the number of connections to other vertices and how important those vertices are. This measure is found mathematically. There are many other important measures you can find by analyzing a network, such as Betweenness Centrality and Degree Centrality. NodeXL is a plugin for Excel that allows you to analyze networks by creating network graphs and calculating metrics such as these. It sounds a little confusing, but basically these tools are used to figure things about about a network.
If you examine a small network’s graph, like Mirrix’s Facebook Group, you can see the people who are most active in the group and most central in the network. In the graph below, people are represented by pink dots. Each line is an interaction between people (so a “like” or a comment on a post). The larger the circle, the more Eigenvector Centrality a person has (so, the more influence a person has in the network).
This is an actual graph of our Facebook Group likes and comments from the week of 2/20 to 2/27.
The larger dots show higher Eigenvector Centrality (or, in plain terms, higher interaction within the group).
This graph was made using NodeXL.
This contest, which will last from March 1st to April 1st, will determine the person who is a member of our Facebook Group and has entered the contest who has the highest Eigenvector Centrality (based on likes, posts and comments) over this one-month period. We will calculate this number using NodeXL and make a graph of the interactions in our group over that time period.
Basically, we are looking for the person with the most influence in the group. Interacting with the group (by posting, commenting and liking) is what will increase your Eigenvector Centrality and will help you to win!
The winner will get a $100 Mirrix Looms gift certificate towards a loom or Mirrix Loom Accessory
20 bobbins of hand-painted silk (worth about $115) of whatever colors (from the ones currently painted) the winner likes.
How do you enter? First, join our Facebook group. Second, enter your name into the contest by filling out the form below (and remember to read the fine print). Third, start liking, posting and commenting in our Facebook group. We’ll announce the winner after April 1st.
