Update #1

I presented yourHistory at ICT.OPEN 2013:

The slides of my talk are up on SlideShare:

yourHistory – entity linking for a personalized timeline of historic events from David Graus

And we got nominated for the “Innovation & Entrepreneurship Award” there! (sadly, didn’t win though ;) ).


Original Post

yourHistory - OKConference poster

For the LinkedUp ChallengeΒ Veni competitionΒ at the Open Knowledge Conference (OKCon), we (Maria-Hendrike Peetz, me, Daan Odijk, Ork de Rooij and Maarten de Rijke) created yourHistory; a Facebook app that uses entity linking for personalized historic timeline generation (using d3.js). Our app got shortlisted (top 8 out of 22 submissions) and is in the running for the first prize of 2000 euro!

Read a small abstract here:

In history we often study dates and events that have little to do with our own life. We make history tangible by showing historic events that are personal and based on your own interests (your Facebook profile). Often, those events are small-scale and escape history books. By linking personal historic events with global events, we to link your life with global history: writing your own personal history book.

And try out the app here!

It’s currently still a little rough around the edges. There’s an extensive to-do list, but if you have any feedback or remarks, don’t hesitate to leave me a message below!

It’s a wrap!

This category can soon be archived ;)! Earlier this week I handed in my final paper, and yesterday was the day of my final presentation. It was a great day and I’m really excited about embarking on my next adventure. I will soon start as a PhD candidate at the University of Amsterdam, on a very exciting project in ‘Semantic Search in e-Discovery’ at the Information and Language Processing Systems group. Naturally, this blog will keep the world informed of my work and projects ;). Exciting times!

“(a) A sagittal reconstruction of a coronally acquired magnetic resonance imaging (MRI) scan, at the level on which the cingulate gyrus was measured. The area outlined represents the portion of the scan used to orient the operator to the landmarks of the cingulate. A box has been placed over the region of interest in one hemisphere. (b) A diagram of the cingulate gyrus divided into the rostral portion of the anterior cingulate (RAC), the caudal portion of the interior cingulate (CAC), and the posterior cingulate (PC). Adjoining landmarks include the corpus callosum (CC), the lateral ventricle (Lat. Vent.), and the thalamus (Thal.). (c) The region of the cingulate gyrus measured in the present study, as delineated on the MRI scan of a control subject. […] ” (snippet)
