artificial intelligence

noun phrase

1 / 15

Foundation

Artificial intelligence allows computers to learn and make decisions.

Intermediate

Artificial intelligence is already being used in healthcare to detect diseases from medical images more accurately than human doctors.

04

digital divide

noun phrase

4 / 15

Intermediate

Critics argue that mass government surveillance undermines civil liberties and the right to privacy.

Band 9

The normalisation of pervasive digital surveillance — rationalised through the discourse of security and efficiency — represents a profound challenge to the liberal democratic principles of privacy, autonomy, and the presumption of innocence.

algorithm

noun

6 / 15

Intermediate

Technological innovation has transformed communication, healthcare, and transport over the past two decades.

Band 9

Sustained economic prosperity in the knowledge economy is contingent upon the continuous generation of high-value innovation — a process that requires not only investment in research infrastructure but also an institutional culture that tolerates productive failure.

Common collocations

noun phrase

9 / 15

Definition

The amount of time spent using a device such as a smartphone, tablet, computer, or television screen.
