Interface Summary

Interface	Description
DataModelBuilder	Implementations of this inner interface are simple helper classes which create a DataModel to be used while evaluating a Recommender.
IRStatistics	Implementations encapsulate information retrieval-related statistics about a Recommender's recommendations.
RecommenderBuilder	Implementations of this inner interface are simple helper classes which create a Recommender to be evaluated based on the given DataModel.
RecommenderEvaluator	Implementations of this interface evaluate the quality of a Recommender's recommendations.
RecommenderIRStatsEvaluator	Implementations collect information retrieval-related statistics on a Recommender's performance, including precision, recall and f-measure.
RelevantItemsDataSplitter	Implementations of this interface determine the items that are considered relevant, and splits data into a training and test subset, for purposes of precision/recall tests as implemented by implementations of RecommenderIRStatsEvaluator.
