Last night, I had the privilege of speaking to fellow CMU School of Computer Science alumni at Fidelity’s Center for Advanced Technology in Boston.

Thus encouraged, […]

I just received an announcement from the SIG-IRList about the flickling challenge, a “game” designed around known-item image retrieval from Flickr. The user is given an image (not annotated) and the goal is to find the image again from Flickr using the system. I’m not sure how well it will catch on with casual gamers–but […]

The Magic Shelf

May 27th, 2008 · Comments Off · Uncategorized

I generally shy away from pimping Endeca‘s customers here at The Noisy Channel, but occasionally I have to make an exception. As some of you may remember, Borders made a deal several years ago to have Amazon operate their web site. Last year, they decided to reclaim their site. And today they are live, powered […]

The following is a public service announcement. As some of you may know, I am the primary author of the Human Computer Information Retrieval entry on Wikipedia.

Back from Orlando

May 22nd, 2008 · Comments Off · Uncategorized

I’m back from Endeca Discover ’08: two and a half days of presentations, superheroic attractions, and, in the best tradition of The Noisy Channel, karaoke. A bunch of us tried our best to blog the presentations at http://blog.endeca.com/. All in all, a fun exhausting time, but it’s good to be back home. So, for those […]

A Utilitarian View of IR Evaluation

May 15th, 2008 · 7 Comments · General

In many information retrieval papers that propose new techniques, the authors validate those techniques by demonstrating improved mean average precision over a standard test collection.

The articles were a worthwhile read, and yet they weren’t exactly what I was looking for. Let me explain. In fact, let’s start by going back to Cranfield.
