Text In, Insight Out
Most NLP follows a pipeline: raw text flows in one end and structured, useful insight comes out the other. 🔄
Step 1: Collect Text
Everything starts with raw text from emails, reviews, or web pages. It is noisy and exactly as a human typed it.
Step 2: Clean It Up
Next you clean the text, fixing case, stripping stray symbols, and removing junk so later steps see a tidy version.
Step 3: Tokenize
Tokenization splits a sentence into pieces, usually words, giving you a list the computer can count and compare.
Step 4: Normalize
You then normalize, lowercasing and reducing words to a base form so running and runs are treated as the same idea.
Step 5: Turn Into Numbers
Models need digits, so you convert tokens into features, often counts or scores that represent each piece of text.
Step 6: Model It
A model takes those numbers and learns a task, like sorting reviews into positive and negative buckets.
Step 7: Get the Output
Finally the pipeline returns an output: a label, a score, a summary, or an answer you can use in an app.
Each Step Feeds the Next
The steps run in order. Clean text helps tokenizing, good tokens help features, and good features help the model.
Garbage In, Garbage Out
Skip the cleaning and your model learns from noise. The early, humble steps quietly decide how good the result is.
A Mental Map
Keep this pipeline in mind: collect, clean, tokenize, normalize, vectorize, model, output. Every later lesson fills in one box. 🗺️

Recap
An NLP pipeline walks text from raw input to insight: clean, tokenize, normalize, vectorize, model, and output. 🎯
