Semantic analysis (computational)

Semantic analysis, my little friend, is like when a computer understands what words are trying to say.

Imagine you had a robot friend that speaks a different language than you. You give your robot a list of sentences and ask it to tell you the most important information in each sentence. This is what semantic analysis does, but instead of a robot, it’s done by a computer.

The computer uses fancy algorithms to recognize and understand the meaning of the words in sentences. It can look for important words like “dog” or “love” and then group them together to find out what the sentence is about.

Just like when you learn to read, the computer uses special rules to work out whether words have special meanings based on how they are used. For example, when you say "I ate a big apple," the computer knows that "apple" is a fruit and not a computer like the kind you're talking to right now.

So, in summary, semantic analysis is when a computer reads and understands what different words mean in a sentence so it can tell you what's being said.
