These foundational terms define the core building blocks of artificial intelligence in human resources. Before exploring specialized applications, learning these concepts is essential for understanding how AI thinks, learns, and transforms talent strategies. From basic artificial intelligence to advanced language models, these nine terms form the vocabulary every HR leader needs to navigate AI-powered talent solutions with confidence.

Artificial Intelligence (AI)

Artificial intelligence is technology that enables machines to perform tasks typically requiring human intelligence, such as recognizing patterns, understanding language, and solving problems.

• What it does for candidates/employees: Creates smoother experiences through faster responses and personalized interactions at scale.

• What it does for talent acquisition and talent management teams: Reduces repetitive work while generating insights that support better decision-making.

Examples in action:

• A candidate engages with conversational AI to find suitable jobs instead of navigating traditional career sites manually.

• An employee receives relevant opportunities automatically — gigs, learning, and career paths that are matched to their experience level and skills.

Machine Learning (ML)

Machine learning is a subset of AI that enables systems to improve performance over time through experience and continuous feedback. Rather than following explicit programming, machine learning algorithms analyze data to identify patterns and make predictions automatically.

• What it does for candidates/employees: Improves matching between people and jobs, connecting talent to opportunities with greater speed and accuracy.

• What it does for teams: Strengthens predictions about hiring, performance, and retention while delivering actionable insights for decision-making.
