We Won SemEval!

Actually, I'm not sure how we won, but we did...we've been getting a lot of congratulations from professors in our department and such, but I still don't know how we had the best system. It seemed so last minute and ad hoc. We had 1 1/2 months to code our system, and there were 13 other teams from around the country(and in the UK).

Also, I am excited about Feisty Fawn, the next version of Ubuntu, which is being released on the 19th of April. If you haven't tried out Ubuntu yet, this is your chance! It's supposed to have the state of the art in networking and will include many multimedia codecs by default.

I thought you might be interested to hear about a project I've been working on :-)

This semester I'm taking a seminar in which we are competing in a sort of academic task called SemEval 2007. SemEval offers the oppourtunity for participants(mostly teams at universities, like ours) to attempt a variety of tasks related to automated semantic evaluation. The professor who is teaching the course, Roxana Girju, helped to organize one of the tasks, and so of course we are working on that one. It is task 4, "Classification of Semantic Relations between Nominals".

So, what does that entail? Basically, we're given a bunch of sentences with two nouns marked on each sentence, and most of the time the exact meanings of the marked nouns. We must write a computer program that automagically determines whether or not the two marked nouns have a particular semantic relation. There are seven semantic relations that we have to sort out, so it's not too bad. Here's an example of what we get:

001 "The period of [e1]tumor shrinkage[/e1] after [e2]radiation therapy[/e2] is often long and varied (mean months)."
WordNet(e1) = "shrinkage%1:11:00::", WordNet(e2) = "radiation_therapy%1:04:00::", Cause-Effect(e2,e1) = "true", Query = "* after radiation therapy"

The first line is the sentence, which has "tumor shrinkage" and "radiation therapy" marked. The second line is a reference to the exact Wordnet definition, or "sense", of each marked noun. It also displays the relevant semantic relation, Cause-Effect, which in this case is labeled as a true relation between the two nouns. That is, radiation therapy causes tumor shrinkage, which is straightforward enough for anyone to understand, and this is what is meant by Cause-Effect. The Query indicates a Google search that led the task moderators to this sentence, which comes from the web.

So what's the point of doing this task? A primary application is as an aid to question answering computer programs. For example, suppose you're a doctor and you want to know what shrinks tumors. Suppose there's this amazing program where the doctor can just type in a question and out comes the answer: "radiation therapy". In order to get this answer, the program can search the web, find a sentence like the one given above, and somehow figure out that "radiation therapy" is in a Cause-Effect relationship to "tumor shrinkage". To figure out this "somehow" is the goal of this task.

The deadline for submitting our results is Sunday, so I'll let you know how we do!

Jorge Cham Visits UIUC

This evening I had the pleasure of attending a lecture by the creator of the web comic known as Piled Higher and Deeper. This comic, if you haven't read it, is a very inspiring/depressing/comedic take on the life of a graduate student(that is, my life). What I enjoy about these comics is that I can relate precisely to many of them. Jorge Cham has indeed been through grad school at Stanford, has a PhD in Mechanical Engineering, and understands the plight of the grad student.

The gist of a Jorge Cham talk is to use many comedic devices shown through his various cartoons and a fairly well-reasoned argument why procrastination is healthy for grad students. Supposedly 1 in 200 graduate students makes an attempt at suicide O_O How lovely, indeed. That's what happens when you don't procrastinate! No, really! :-P

A few highlights. In his talk, Jorge brought up that only 4 Hollywood movies about grad students have ever been made. These are: Hulk(2003), A Beautiful Mind(2001), Real Genius(1985), The Seniors(1978). In the question session following his talk, I asked approximately: "Since you brought up the scarcity of movies made about grad students, would you ever consider turning your comic strip into a movie?" His answer was, roughly: "Well, that would be very interesting to try, and since I live in Pasadena, which is right near Hollywood, you pretty much have to be working on a screenplay. So maybe I'll give it a shot." Pretty promising answer I think :-)

An undergraduate Linguistics student I know, Ben Lawitts, found me after the talk and told me he was going to try and get Jorge to go to The Blind Pig and have a drink with the Linguistics grad students who meet there every Thursday night. Jorge wasn't against the idea, but methinks he won't end up there tonight. What was funny is that this Ben Lawitts just got his head shaved, and had Jorge sign his head! Jorge was a bit taken aback at first, but drew a lightbulb and signed Ben's head, giggling the whole time. The director of the Graduate College asked to take a couple pictures of Ben, which I was promised to receive in due course, so you will get to see this. A funny quote from Jorge after agreeing to sign Ben's head: "This doesn't mean you'll be in my comic!"

Lastly, a school newspaper journalist interviewed Ben and me about the talk, and I expect my comments will appear in The Daily Illini tomorrow. ^_^

Halfway Done!

I'm halfway done with my PhD program! Yay!  
A week ago I deposited my qualifying papers. Now, I just have to defend my papers next semester, and if I pass, I get 
a Master's degree in Linguistics. Whew. 
I just graded my last HW set, so I'm completely done with the semester.

I'm going to Lexington, Kentucky, where I will spend Christmas with my girl Rachel and my Dad's side of the family. We stay at my Uncle Norb's, who with my Aunt Tammie are great hosts to Rachel and me. I love staying there.  

I'm also going to visit Nana and Aunt Debra in the Fort Lauderdale, Florida area, for the New Year's time.  I'm looking forward to being in a tropical climate in the winter.
