2. Introduction to Natural Language Processing (NLP) :
1. NLP is a subfield of artificial intelligence focused on the interaction
between computers and human language.
2. It involves the ability of machines to understand, interpret, and
generate human language.
3. NLP bridges the gap between human communication and computer
understanding.

3. Why NLP is Crucial for Data Science
Handling Unstructured Data:
1. Handling Unstructured Data : A large portion of data generated
today is unstructured (e.g., text, social media, emails). NLP techniques
are essential to extract meaningful insights from this data.

2. Improving Decision-Making : By analyzing customer feedback,
market trends, and social sentiment, NLP helps data scientists
make informed decisions.
3. Enhancing Data-Driven Strategies : NLP enables businesses to
develop strategies based on real-time data analysis, increasing agility
and responsiveness.

4. Core NLP Techniques and Applications :
1.Text Preprocessing : Tokenization, stemming, lemmatization, and
removing stop words to clean and prepare text data for analysis.
2. Sentiment Analysis : Determining the sentiment (positive, negative,
neutral) in text data, widely used in customer feedback analysis and
social media monitoring.
3. Named Entity Recognition (NER) : Identifying and classifying key entities
(e.g., names, organizations, locations) within text, useful for information
extraction and summarization.

5. 5.Machine Translation : Converting text from one language to another,
crucial for multilingual customer support and content globalization.
4.Topic Modeling : Discovering abstract topics within text data, useful in
content categorization and recommendation systems.
6.Text Summarization : Automatically generating a concise summary of
long documents, aiding in quick information retrieval and decision-
making.

8. 2. Data Privacy and Security : Handling sensitive information securely
while processing large volumes of text data.
1.Language Ambiguity : Words and sentences can have multiple
meanings depending on context, making accurate interpretation
challenging.
Challenges in NLP :
3. Bias and Fairness : Ensuring that NLP models do not perpetuate or
amplify biases present in training data.
