NLTK has a function called regexpparser to parse the Part-of-Speech tagged sentence. I cannot find a good and short explanation for the Regex pattern. So here is one.
- 1. Part-of-Speech tagging
- 2. Regular Expression regex grammar
This action simply tag your tokenized words with the word type, for example, Verb, noun, adjective, etc.
1.1. The tags and explanations
The full list of tags can be shown when running the command
For the full list of explanations, scroll to the bottom of this post.
1.2. Tagging them
For example, when you have the sentence:
The process should be something like this
The regular expression with nltk tokens is quite different than normal text. The grammar treats each token as a string of text, and apply the regex pattern on that string with matched to the position of the token in the sentence.
Below I will present a list of grammar, from the most simple to the more complex one, using the same sentence above
2.1. Exact match
2.2. Skip some tags
We will skip all tags between The and fox (between DT and NN tags)
Explanation: Divinity 2 loading screen fix.
<.*> means match every tag. The dot (.) mean match every character (of the tag). The asterisk (*) means repeat match from 0 to unlimited time.
The next asterisk (*) right behind it means repeat the matching tags from 0 to unlimited time.
2.3. Match all tags start with a character
