It’s been a looooong time since I’ve posted on this blog. I’ve been busy, among other things, playing with my new MacBook Air. πŸ™‚

One of the coolest things about the new MacBook lineup is the updated multi-touch. Now I can use 3, or even 4!!! fingers to manipulate within and between applications.

Firefox, my browser of choice so far, has a beta version, Firefox 3.1 Beta 2, which supports multi-touch. So I can use 3-finger swipe motion to go back, forward, top of page, bottom of page, and use two-finger motions to zoom in & out, and piching/twisting motions to switch tabs. All you MacBook users, you MUST try it out!


Try using Google’s new feature, “SearchWiki”, where you can promote or remove a search result. You have to be logged into your google account to do the promotion/removal, and the action will only affect your search results. But your action will show up as part of the community comments when other people view the results you have promoted/removed.

**Alas, it did not work for my Google Korea search results, I had to switch to English Google to see the effect.

Read this google post for a bit more information.

As bloggers, we are aware that there must be good blogs out there that we don’t know about. Putting aside the question of, do you really want to read another blog?, here is an academic paper on recommending blogs based on some query words. This problem is different from the traditional query-search on the Web because, well, blogs are different from webpages. Read the paper to find out more:

J. Arguello, J. L. Elsas, J. Callan, and J. G. Carbonell. (2008.) “Document representation and query expansion models for blog recommendation.” In Proceedings of the Second International Conference on Weblogs and Social Media.

This is much closer to my research than most other posts in the blog… From Daniel Tunkelang (of Endeca) ‘s blog.

Peering into the micro world – The Big Picture –

A team of University of Michigan researchers has recently created a set of electron microscope images of carbon nanotube structures depicting images of U.S. President-elect Barack Obama.

Slightly off topic, but fascinating stuff!!!!

Tomorrow is my birthday!

I would like to urge *EVERYONE* (yes, that’s YOU!!!) to leave me a short birthday wish.

I just want to know who my readers are (though you don’t have to reveal your identity).

There aren’t that many readers, partly because I haven’t been blogging for very long, and I have not been active in visiting other blogs. But lately I’ve been getting at least a dozen views per day, more on days when I make a new posting.

Let’s see if this experiment works.

There is an article in the New York Times that newspapers were selling like a hot commodity post-election. I wasn’t in New York to pick up the Times, but here is a Chinese newspaper I got at the Four Points @ Sheraton in Beijing.


Today is the Presidential Election Day in the US. Since I don’t live there anymore, I feel a little aloof, but I have a strong preference for one candidate over the other, so I am following it very closely.

Here is something the New York Times is doing. “What one word describes your state of mind?” And they tally it up for the three categories: everyone, McCain supporters, Obama supporters. They use visualization techniques similar to tag clouds, where they put the most popular words in big letters, and the less popular ones in smaller letters. For the McCain supporter words, they use red font, for the Obama supporters, they use blue font.

It’s a hint that people outside of research are picking up on the trend of caring about emotion language on the Web. It’s pretty cool, check it out!

Here is something interesting. It is a new way to explore and browse data. David is a friend through MIT, and though he and I both graduated, his work keeps me interested. I couldn’t figure out how to embed a Vimeo video here, so you’ll just have to click on the link to view it. Instead of trying to explain what Freebase does, I’ll let him do the talking. πŸ™‚

I just made this logo (and updated versions) for our Users & Information Lab. I possess very very little artistic creativity, so this is pretty much all I could come up with. Any good graphic designers out there?

Our research statement is:

We engage in active research for delivering information that satisfies the user. We strive to re-define what it means for information to be relevant–to go above and beyond the popular notions of word- and phrase-based queries and page ranks. We ponder about re-representing the user–to understand and model at a deeper and higher level than preferences and profiles.

Stay tuned for our website. We just ordered a server. πŸ™‚
