Table 1 Definition of three metrics that describe an information cascade
From: How did Ebola information spread on twitter: broadcasting or viral spreading?
Metrics | Definitions |
|---|---|
Cascade size | The number of total retweets received by an original tweet. The cascade size describes the popularity of the seed message |
Cascade scale | The percentage of all retweets that were retweeted directly from the original tweet. The higher the percentage is, the more likely the diffusion cascade is dominated by the broadcast model |
Cascade depth | The number of generations in a diffusion path. A large depth value may suggest a long chain of information diffusion and thus implies viral spreading |
