A personality lesson for hot dog season

It's unusual for Wittgenstein to appear in my day. I'm no philosopher. So, when Mr. Wittgenstein shows up twice in my day, it's something.

First was the Wittgenstein quote in Calvino, "For what is hidden … is of no interest to us." Then came this passage amid my vacation magazine catch-up, from Wired's March issue, on Google refining its search:

Google's synonym system understood that a dog was similar to a puppy and that boiling water was hot. But it also concluded that a hot dog was the same as a boiling puppy. The problem was fixed in late 2002 by a breakthrough based on philosopher Ludwig Wittgenstein's theories about how words are defined by context. As Google crawled and archived billions of documents and Web pages, it analyzed what words were close to each other. "Hot dog" would be found in searches that also contained "bread" and "mustard" and "baseball games" — not poached pooches. That helped the algorithm understand what "hot dog" — and millions of other terms — meant. "Today, if you type 'Gandhi bio,' we know that bio means biography," Singhal says. "And if you type 'bio warfare,' it means biological."

The upshot, to me? Science recommends oversharing.

Thoughts?
