Natural Language Processing (NLP) Basics

NLP Basics क्या है?

NLP Basics ka matlab hai: NLP helps computers understand and process human language such as text, speech and documents. Simple words me, ye topic practical Python programs likhne me direct use hota hai.

Is topic ko sirf definition ke liye nahi, balki processing text jaise real examples ke liye practice karein.

यह क्यों सीखना जरूरी है?

• Ye processing text me kaam aata hai.
• Ye sentiment analysis se bhi connected hai.
• Isse aap code ka output aur errors better samajh paate hain.

Important Terms

Syntax / Basic Pattern

Basic idea: pehle data तैयार करें, phir Python logic apply करें, aur finally result display करें.

text = "Python is powerful and easy to learn"
words = text.lower().split()
print(words)
print("Total words:", len(words))

Complete Example Program

text = "Python is powerful and easy to learn"
words = text.lower().split()

print(words)
print("Total words:", len(words))

Expected Output

Program Explanation

• text = "Python is powerful and easy to learn" stores a value in text.
• words = text.lower().split() stores a value in words.
• print(words) displays information or calculated result on the screen.
• print("Total words:", len(words)) displays information or calculated result on the screen.

Practical Uses

• Processing text.
• Sentiment analysis.
• Text classification.

Common Mistakes

• Training and testing the model on the same data.
• Using an algorithm without understanding the input features.
• Reporting only accuracy without checking actual mistakes and limitations.

Practice Tasks

1. Program ko nlp-basics.py file me type karke run karein.
2. Values change karke output compare karein.
3. processing text par ek छोटा example banayen.
4. Logic ko apne words me 5 lines me likhein.

सारांश

Natural Language Processing Basics ko tab complete maanenge jab aap iska meaning, example, output aur practical use clearly explain kar saken.
