Phase One-Building the Logic to Find Links and Combine into Networks

Phase One specifies the logic to find specific types of links between specific types of nodes, and determines which of these types to combine into networks. The following table describes the steps and includes the Developer Tool used for the completion of the steps of Phase One.

Table 7-2 Phase One Steps and Tools

Step	Action	Developer Tool
1	CreateSource Link dataset.	DataSetEditor
2	Createnew Network Definition.	NetworkDefinition Editor
3	Add Source Link dataset to the Network Definition.	NetworkDefinition Editor
4	Specify node and link information in each source linkdataset.	NetworkDefinition Editor

Step 1: Identify the entities in which you are interested and the kind of relationships that connect them. Specify this information by using the DataSet Editor to create Source Link datasets. Each Source Link dataset captures the logic to find a specific relationship (that is, a link) between two specific types of entities (that is, nodes). You must create a separate Source Link dataset for each type of link or types of nodes that are grouped into networks. Each Source Link dataset must also contain basic information about the link and each of the nodes (for example, From Node key, From Business key, To Node key, or To Business key).

Note:

The From Node key, From Business key, To Node key, and To Business key refer to a business key. A business key is a data field that the business uses to identify an Entity.

Step 2: Create a Network Definition to combine the pieces of your template together. Use the Network Definition Editor to create a Network Definition. A Network Definition represents a template that is used to detect networks.

Step 3: Use the Network Definition Editor to add the Source Link dataset to the Network Definition, which specifies the type of links and entities that should be evaluated to detect networks. Adding multiple Source Link datasets to a Network Definition enables the creation of networks that contain links and nodes of multiple types. This is useful in detecting complex networks.

Step 4: Use the Network Definition Editor to specify the node and link information within each Source Link dataset and to determine the columns in each dataset that represents each component of the link. For example, identify the columns in each Source Link dataset that represent the IDs of the From Node and the To Node. If appropriate, you will identify the Link Weight, a measure of the value or importance of the link. Refer to Components of the Network Definition Editor, for additional information about the columns and their definitions of the Network Definition Editor.
