Natural Language Processing We are leaning NLP! Tokens: We,are,learning,NLP,! Syntax means proper arrangement of words according to rules. Now when syntax makes sense it becomes semantics His future is very bright. (semantics) Data Processing 1) Pre-processing steps (Text Normalisation) Example words like slang,short form,misspelled,special meaning  character needs to be converted into canonical form.    Words Canonical form   b4,beefore,bifore           before Gni8                        Good night   tysm    Thank you so much gr8,grt                       great   Statement:   Gn tke care Perform text normalisation Answer: Good night take care. (corpus)   There are multiple steps for performing text normalisation: 1. Sentence Segmentation   2. Tokenization 3. Rem...
