···66771. A mechanism that generates an up-to-date and comprehensive DAG of relevant dependencies given a source node
882. A mechanism that fills the graph with relevant weights. These weights represent the latent item utilities. There can be many ways of getting to them!
99- 1. Aggregating human preferences (polls, pairwise comparisons, ...)
1010- 2. Using prediction markets
1111- 3. Getting weights from an AI model
1212- 4. Collaborative Filtering
1313- 5. Having experts fill weights manually
