University technologies ... more tag clouds

If you've spent enough time at a university, you'll have come into contact with the "Office of Technology Commercialization", "Office of Technology Licensing", or someone responsible for what's called "technology transfer". Essentially, these people are responsible for finding problems that can be solved using technology created by the university and making that technology available to the right people ... for a fee of course.

If this surprises you, consider reading the primer offered by Stanford's OTL. The Bayh-Dole act specifically intended to make federal government funded technology more accessible.

So what's this got to do with tag clouds? Well, just think about thousands of people walking around, some with ideas, some with solutions, some with problems ... we know they don't use all the same terms, so how can these people find each other productively? Think about why Google offers search suggestions. You may be looking for "software", but I might always refer to "algorithms" or "programs".

That's the power of a tag cloud. When words are placed out of context, the brain is probably forced to be more open about interpretation.

The nice people at iBRIDGE know this (or unknowingly benefit from it). Try it out. Try searching for "natural language" and see how the tags to the right help out.

For another example, look at Nestlé's US and EP patent filings. You could either scan 1,436 entries to find references to "ice cream", or you could simply click "ice", "cream", "confection", or "frozen".

So here's my question: why don't other technology search sites like yet2.com, e-ip.com, etc. use tag clouds? Don't make me click through pages of results -- give me a tag cloud!

The Experiment

Few things engage me as much as text mining. I've had some time to play recently so I created a new toy that allows me to catch up on the news in an interesting way.



The essential mechanism is simple: use RSS to get data from a few news feeds, do some simple term analysis, add a sprinkle of "intelligent tagging", and presto!

Take a look: News site

You can click each term in the tag cloud to see a list of news articles where the term appeared. You can click over to the original article if it gets your attention.

Tag clouds are not new. The presentation here isn't half as pretty as wordle. But it was fun to create and I hope you enjoy it as well.
