Software to inflect English

Question

Is there any software out there which can do the following?

Given an English sentence like

"He likes baked beans",

I change "he" to "I" and the sentence changes to

"I like baked beans"

(note the S)

or

"She has her hair in a ponytail"

I change "she" to "he" and the sentence changes to

"He has his hair in a ponytail".

Similarly, can change the sentence into past tense,

"She had her hair in a ponytail".

Does such software even exist?

Answer 1

I don't know of any.

However, you might want to have a look at nltk.org (Natural Language Toolkit) which is a Python library for natural language processing that has many features that could potentially be very helpful, such as POS (part of speech) tagging.

This is, of course, if you would be fine with writing such a software yourself, sorry if it is not relevant to what you want to do.
