Remarks
Two types of analysis models are available in Microsoft Commerce Server 2000. A Prediction model is a collection of decision trees (called a dependency net) and is used either to produce a ranked list of recommendations, such as products to advertise, or to fill in missing user profile information, such as age. A Segment model is based on the process of clustering (segmentation) and is used to group similar users into segments of a population.
An analysis model is associated with a model configuration. More than one analysis model can be associated with the same model configuration. The model configuration contains attribute and case information used to build the analysis model. A case is all the information known about a user, such as profile data and transaction data. A typical model uses between 10,000 and 20,000 cases with a resulting size of between 100 kilobytes (KB) and 10 megabytes (MB).
The PredictorServiceAdmin object contains lists of the available analysis models and model configurations. The PredictorServiceSiteAdmin object provides methods for maintaining the analysis models and model configurations. The PredictorClient object loads the appropriate analysis model and makes the actual prediction.
The generation of an analysis model occurs in an individual build thread. A single instance of the PredModelBuilder object may control multiple simultaneous build threads. If a problem occurs in a build thread, that specific thread may be paused or terminated.
