: Algorithms extract "mood" by analyzing color palettes, lighting ratios, and frame density. A "dark and gritty" noir film is identified not just by a tag, but by its specific visual signal.

: Every movie or song is converted into a multi-dimensional vector. The "distance" between these vectors represents how similar they are based on thousands of hidden features.

: By processing scripts and subtitles, systems can identify recurring narrative patterns (e.g., "the hero’s journey" or specific character archetypes) across thousands of titles.
