Lab 3: Building a Segment Model

  • Article

You use the Segment Viewer module to perform segmentation (or clustering) analysis. In segmentation analysis, users are grouped into segments according to their behavior on the site and by their properties, such as age and gender.

The result of the segmentation process is a Segment model. The Segment model describes the shared characteristics of the users belonging to a segment or a group of segments. Segments and segment groups are created in Commerce Server Manager from data in your Data Warehouse.

You use the Segment Viewer module to examine a single segment or to compare one segment to another. You also use the Segment Viewer module to create a summary report of all your segments and to export a segment to a list.

To create a Segment model, do the following:

  1. Click Start, point to Programs, point to Commerce Server 2002, and then click Commerce Server Manager.

  2. In Commerce Server Manager, expand Commerce Server Manager, expand Global Resources, expand Predictor on <server name>, expand Predictor Service, and then select Model Configurations.

  3. In the Commerce Server Manager content pane, right-click DemoTransactions, and then select Build.

  4. In the Build Model Properties dialog box, do the following:

    Use this To do this
    Name Type Software Segments.
    Model type Select Segment asthe analysis model type.

  5. Click Next.

  6. In the Build Model Properties dialog box, in the Measured accuracy sample fraction box, type 0.1, and then click Finish.

    • Measured accuracy sample fraction is the fraction of properties that are used as input to the predictions. For example, specifying an input attribute fraction of 0.05 selects the most significant 5 percent of input attributes. The default value is 1.0, which includes all attributes as inputs for prediction. Values less than 1.0 are recommended if the number of attributes is very large, such as product recommendations for a catalog with over 1,000 products.
