3 An illustration of dependencies in a simple user-based recommender system, and the order in which components refresh their data structures Just about any reasonable file will do, such as the simple comma-separated value file from chapter 2. Each line contained one datum: user ID, item ID, and preference value. Tab-separated files will work too. gz, respectively. It’s a good idea to store this data in a compressed format, because it can be huge, and it compresses well. 3 Refreshable components While we’re talking about loading data, it’s useful to talk about reloading data, and the Refreshable interface, which several components in the Mahout recommenderrelated classes implement.
Com> Running a first recommender engine 15 might technically be called a collaborative filtering framework. An example of this will follow in chapter 5, where you’ll build a recommender for a dating site. For now, though, it’s time to experiment with collaborative filtering within Mahout by creating some simple input and finding recommendations based on the input. 2 Running a first recommender engine Mahout contains a recommender engine—several types of them, in fact, beginning with conventional user-based and item-based recommenders.
Before we go on to study recommender engines in detail, it’s important to spend some time with another foundational concept for recommenders in Mahout: the representation of data. We’ll look at that in the next chapter. Download from Wow! com> Representing recommender data This chapter covers How Mahout represents recommender data DataModel implementations and usage Handling data without preference values The quality of recommendations is largely determined by the quantity and quality of data.
