Sliding window based part-of-speech tagging
Imagine you have a basket of fruits and you want to figure out what type of fruit each one is. You could look at each fruit and try to guess what it is, but that would take a long time. Instead, you could group the fruits together in a window and look at them as a group to figure out what each fruit is.
In the same way, sliding window based part-of-speech tagging is a way of figuring out what type of word each word in a sentence is by looking at groups of words at a time. Like the fruits, it is easier to look at several words at once and figure out what parts of speech each word is.
To start, we take a sentence and divide it into groups of words using a sliding window of a fixed size. For example, if we have a sentence like "The cat sat on the mat", we might create a window of three words at a time, like so:
"The cat sat"
"cat sat on"
"sat on the"
"on the mat"
We then look at each group of words and try to figure out what part of speech each word is. For example, "The" is a determiner, "cat" is a noun, and "sat" is a verb. We can use a pre-defined set of rules or a machine learning algorithm to predict what part of speech each word is.
Once we have figured out what part of speech each word is in a group, we can move the window forward by one word and repeat the process. For example, we would move the window from "The cat sat" to "cat sat on", and then to "sat on the", and so on, until we have gone through the entire sentence.
By using sliding windows to group words together and analyzing each group as a whole, we can more easily and accurately determine the part of speech of each word in a sentence.
