Feature-rich networks are complex network models that provide one or more features in addition to the network topology. In attributed networks, attributes are assigned to the nodes to describe the corresponding entities. For example, in a friendship network, the actors can be described by their genre and their age. Which two alternative network models can be used to model interaction over time or to model each attribute by a specific relationship? (Choose two.)
To model interaction over time, temporal networks are appropriate because they account for changes and dynamics in the network's structure over time. Multilayer networks are suitable for modeling each attribute by a specific relationship, as they allow different layers to represent various types of relationships or attributes between the same set of nodes, capturing the complexity of real-world systems.
To model interaction over time or to model each attribute by a specific relationship in complex networks, two alternative network models can be used: 1. Temporal Networks (Dynamic Networks) Temporal Networks are used to model interactions that occur over time. In these networks, the connections between nodes are not static but rather change as time progresses. Temporal networks capture the timing and order of interactions, making them suitable for studying dynamic processes within networks. 2.Multilayer Networks (or Multiplex Networks) are used to model networks with multiple types of relationships or interactions between the same set of nodes. Each layer represents a different type of relationship or interaction, allowing the network to capture the complexity of real-world systems where entities interact in various ways.
C. Temporal network: This model explicitly incorporates time into the network structure, allowing for the analysis of interactions that change over time. In a friendship network, for example, you could model when friendships were formed and ended. E. Multilayer network: This model represents different types of relationships or attributes as separate layers within the same network. In a friendship network, you could have one layer for friendship based on age, another for friendship based on genre, and so on.
