Semantic Analysis of Text

Semantic analysis is a branch of natural language processing (NLP) that focuses on extracting the meaning of text. It goes beyond simply identifying words and grammar to understanding the relationships between concepts, the sentiment expressed, and the overall intent of the communication.

Key Steps in Semantic Analysis:

1. Lexical Analysis: Identifying individual words and their parts of speech.
2. Syntactic Analysis: Parsing the sentence structure to understand how words relate to each other.
3. Semantic Analysis: Determining the meaning of words and phrases within their context.
4. Pragmatic Analysis: Interpreting the text based on its intended use and the broader context.

Example Prompts:

1. Sentiment Analysis:

• Prompt: Analyze the sentiment of the following tweet: "I'm so frustrated with this new software! It keeps crashing on me."
• Analysis: The tweet expresses a negative sentiment, indicating frustration and dissatisfaction with the software.
