問題文
The topological link prediction measures in the library score a pair of nodes using only the topology of the graph. What is the basic idea shared by these measures?
選択肢
- Two nodes are treated as closer when the values stored in their node properties are numerically close to each other, which is what allows the measures to be computed without looking at the relationships at all.
- Two nodes with a shorter path between them are treated as closer, and the measures count the relationships along the path between the two of them.
- Two nodes that share more neighbors are treated as closer, so a new relationship between them is judged more likely to appear in future.
- Two nodes are treated as closer when they have similar centrality scores, which the measures read from the property that an earlier centrality run wrote into the projected graph.
