Human–computer information retrieval
Human-computer information retrieval is when we use computers to help us find information we need. You know how sometimes you ask your teacher or parent a question, but they don't have the answer and they tell you to look it up? Well, human-computer information retrieval is like having a super-smart robot friend who helps you find the answer to any question you have.
Here's how it works: Let's say you want to know what the tallest mountain in the world is. You would type your question into a computer search engine, like Google, and the computer would look through all the information it has collected from around the world to find the best answer to your question.
The computer uses a lot of special words and codes to do this. These words and codes help the computer understand what you're looking for and how to search for it. The computer then gives you a list of websites that have the information you asked for. You just have to click on the website you want and read the answer.
Sometimes the computer might not find the answer you're looking for. In that case, you might need to try different words or phrases to help the computer understand what you want better. But usually, the computer is very good at finding the right information, and it helps us learn new things every day!
