AI: what it is and how it works
Artificial Intelligence is a set of technologies capable of learning from data and performing tasks that we normally associate with human abilities: interpreting information, making decisions or generating new content.
AI does not “think” like a human being, but it can learn from examples and recognize patterns. This allows it to answer questions, transform information or generate useful content in very different contexts.
Today, Artificial Intelligence is present in many aspects of daily and university life:
- Assistants that answer questions
- Systems that translate text automatically
- Tools that help write or summarize information
- Applications that generate images or videos from a description
- Platforms that recommend personalised content
To better understand how AI works today, it is useful to distinguish two main uses that coexist in most current tools
1. Analysing information
AI can interpret and organise data to provide useful responses. Its most common functions include:
- Classifying information
- Recognising elements in images
- Suggesting personalised content
- Detecting patterns or trends
- Summarising large volumes of text
These functions allow digital tools to answer questions such as:
- “Which option seems most appropriate?”
- “Which category does this information belong to?”
2. Generating new content
More advanced models can create texts, images, videos, sounds or ideas based on what they have learned. With these capabilities, it is now possible to:
- Write complete texts
- Generate illustrations, videos or designs
- Produce explanations adapted to the context
- Create activities, proposals or ideas
- Generate synthetic voices or music
These functions allow digital tools to generate content in response to questions such as:
- “How could this idea be expressed?”
- “What text, image or proposal can I obtain from this description?”
These capabilities have greatly expanded the possibilities for creation, learning and communication. They enable anyone to interact with a technological system simply by using language and have become central tools in education, research and creative work.
