Let's explain these terms in a way that's easy for anyone to understand, regardless of their background:
Explanation: Imagine you're playing a game where you need to guess a word, and someone gives you a hint or clue to help you guess. That hint is like a "prompt." In computers, a prompt is a message or signal that tells the user what to do next.
Example: When you're at a restaurant, the waiter might ask, "What would you like to order?" That's a prompt, guiding you to place your order.
Steps:
Wait for a response.
Give a hint or message.
Receive a response based on the hint.
Explanation: Think of a sentence as a string of beads. Tokenization is like taking that string and separating each bead (or word) so you can look at them individually.
Example: For the sentence "Birds fly high," tokenization would give us: "Birds", "fly", "high".
Steps:
Take a sentence.
Separate each word.
Look at each word individually.
Explanation: Imagine you have a box of toy blocks, each with a label like "subject," "action," or "object." Parsing is like arranging these blocks to make sense of a sentence.
Example: In the sentence "Dogs bark loudly," parsing helps us understand that "Dogs" are the ones doing something (subject), "bark" is what they're doing (action), and "loudly" tells us how they're doing it.
Steps:
Look at a sentence.
Identify the role of each word.
Arrange the words based on their roles.
Explanation: Sentiment is like gauging the mood of a message. It's about understanding if the message is happy, sad, neutral, or has some other emotion.
Example: "I love sunny days!" has a positive sentiment, while "I miss my old school" might have a nostalgic or sad sentiment.
Steps:
Read a message.
Identify words or phrases that express emotion.
Determine the overall mood or feeling of the message.

For a more in-depth exploration of these topics and related techniques, I recommend checking out the Natural Language Processing course by Stanford University. This course covers a wide range of NLP topics, including the ones mentioned above, and provides detailed explanations and examples.
