Artificial intelligence
Artificial Intelligence ( AI ) is a vast field of computer science dedicated to creating systems and machines capable of performing tasks that would normally require human intelligence. These tasks include learning from data , logical reasoning, problem-solving, environmental perception, understanding , and decision-making. The fundamental goal of AI is not to replicate human consciousness, but rather to simulate cognitive processes to automate and optimize complex operations, allowing machines to process large volumes of information and identify patterns much more efficiently than a human being.
AI manifests itself through various approaches and subfields, the most prominent being Machine Learning and Deep Learning . In Machine Learning, algorithms are trained with datasets to recognize patterns and make predictions without being explicitly programmed for each specific task. Deep Learning, a more advanced subset, uses multi-layered neural networks to analyze data hierarchically and solve even more complex problems, such as image recognition and language translation. Other important areas include Natural Language Processing ( NLP ), which enables machines to understand and generate human language, and computer vision.
In the context of search and retrieval, Artificial Intelligence has revolutionized how search engines like Google operate. AI algorithms, such as RankBrain and BERT, allow the search engine to interpret the intent and context behind queries , rather than simply matching keywords . This results in a experience , where the system understands synonyms, ambiguities, and the relationship between concepts, delivering much more relevant results to satisfy the informational needs . AI also powers features such as voice search, personalized recommendations, and the organization of knowledge in the Knowledge Graph .
