A lot has happened since my last post! I received funding for a 1-year postdoc from the NSF, via the Computing Research Association’s CIFellows program. I’ll be at Northwestern University, in the Center for Technology and Social Behavior, starting in September. I had been waiting to post about this until the list of recipients was released at cifellows.org, but that hasn’t [...]

hierarchies and semantics
In my dissertation experiment, I asked ~60 people from two different graduate schools (or “communities”) on campus to label and organize a set of short documents into a hierarchy (tree structure). They used a web-based interface created specifically for the experiment, that closely resembled the file-and-folder metaphor everybody is used to in Microsoft Windows and [...]
results!
after about a month of on-and-off panic about my dissertation experiment analysis (and too many marathon sessions with crappy R documentation), i now feel confident in saying that YES, i do have some pretty interesting results! i’ll be working on writing everything up for a rapidly approaching paper deadline; i’m guessing i’ll be posting bits [...]
more fun with MDS (and R)
i’ve spent the past few hours futzing (yes, futzing) with some more MDS plots of the document (file) grouping data from my dissertation experiment, visualized this time by document rather than by person. each participant in the experiment organized the same 33 documents into a file-and-folder hierarchy. i chose the documents (document excerpts, really) from [...]
hierarchy structure comparison
in my dissertation experiment, participants recruited from two different intellectual communities on campus organized a set of documents into file-and-folder hierarchies (single-categorization tree structures), using an online system created specifically for the experiment. as part of my analysis, i’m interested in comparing the hierarchies they created, to find out whether there are any reliable differences [...]
