Some of you have expressed interest in knowing more about what I do for work/research/school. ve often said "I teach computers to understand human language." But what exactly does that mean? A lot of things, really, but here's one.
Word sense disambiguation. What does this mean? Many words have multiple meanings. Just as an example, I've looked up "save" in a dictionary, and here are the results. Each line is a "word sense" (the sense of the word). While I think many of us would argue that some of these definitions are really the same... there are still quite a few definitions here.
We humans do a pretty good job of figuring out which meaning of "save" is meant when someone uses the word. But a computer doesn't really have a grasp of the English language. It only knows what I (or someone else) writes into a computer program. I can even write in all these definitions into the program, and the computer will know it is one of them. But which one.
Which sense below do you think my comment in last night's post about "saving friendships" falls under?
