• Natural Language Processing is a field of AI that deals with the interaction between humans and intelligent
systems using natural language.

• The process of interpreting and classifying emotions within text data is known as Sentiment analysis.

• ChatBots, a conversational agent, is one of the great applications of the NLP domain.
• Text normalization is a technical term used for transforming text into a standard form.

• Stemming is an elementary rule based process to remove the affixes of words.

• Bag of Words (BoW) is a simple and popular method to extract features from text documents.
• TFIDF (Term Frequency and Inverse Document Frequency) is a statistical measure used to identify the value
for each word.

• Humans communicate using natural language, while computers operate in binary language (0s and 1s).
Syntax, semantics, and pragmatics pose challenges in enabling effective communication between humans
and machines.

• The formula for TFIDF for a word ‘W’ is TFIDF(W) = TF(W) * log(IDF(W)). It considers both the local relevance
(TF) and global rarity (IDF) of a word in a corpus.

• IDF values are multiplied to TF values for each document in the corpus, emphasizing the significance of
words in individual documents relative to the entire corpus.
