Answer 1

You didn't really give much info, but try this: http://www.nltk.org/

I don't think NLTK does spell checking (I could be wrong on this), but it can do parts of speech tagging for text input.

For finding/matching synonyms you could use something like WordNet http://wordnet.princeton.edu/

If you're doing something really domain specific: I would recommend coming up with your own ontology for domain specific terms.

Answer 2

If you are using Python you can develop a spell checker with Python Enchant. NLTK is good for developing Sentiment Analysis system too. I have some prototypes of the same too

Answer 3

If you are using deep learning based models, and if you have sufficient data, you can implement task specific models for any purpose. With the development of deep leaning based languages models, you can used word embedding based models with lexicon resources to obtain synonyms and antonyms. You can also follow the links below to obtain more resources.
