word sense disambiguation

Word sense disambiguation is the process used to identify which sense of the word is being used in each sentence, when a word has more than one sense. However, this has some problems.

The first problem is that the different meanings of the words sometimes are much closed, so it is difficult to know which one is being used. Another problem is that these systems are tested by humans, and humans don’t agree which the sense of each word is, so it’s impossible for the computer to know the right answer.

We have two different approaches, deep and shallow.

Deep approaches, give an explanation to each sense of the word, but this is impossible in computer format. Shallow approaches, however, analyses the words of the surroundings and decides which of the different meaning is, but it is a problem if words of more than one sense are arround.
