Strong and Weak Ties Consider the following definition and network, in which each edge, except the edge connecting nodes b and c, is labeled as strong (S) or weak (W). Strong triadic closure assumption: if the node x has strong ties to nodes y and z, then there must be a tie, either weak or strong, between y and z. 1. According to our discussion about strong and weak ties, with the strong triadic closure assumption mentioned above, what is the expected label for the edge between b and c? Give a brief explanation for your answer. 2. What are the differences between weak and strong ties in social networks?. Use the above comparison to explain the strength of weak ties in social networks.
