+ <P>Itembased Collaborative Filtering is a popular way of doing Recommendation Mining.</P>
+
+<H3><A name="ItembasedCollaborativeFiltering-Terminology"></A>Terminology</H3>
+
+<P>We have <B>users</B> that interact with <B>items</B> (which can be pretty much anything like books, videos, news, other users,...). Those users express <B>preferences</B> towards the items which can either be boolean (just modelling that a user likes an item) or numeric (by having a rating value assigned to the preference). Typically only a small number of preferences is known for each single user.</P>
+
+<H3><A name="ItembasedCollaborativeFiltering-Algorithmicproblems"></A>Algorithmic problems</H3>
+
+<P>Collaborative Filtering algorithms aim to solve the <B>prediction</B> problem where the task is to estimate the preference of a user towards an item which he/she has not yet seen.</P>
+
+<P>Once an algorithm can predict preferences it can also be used to do <B>Top-N-Recommendation</B> where the task is to find the N items a given user might like best. This is usually done by isolating a set of candidate items, computing the predicted preferences of the given user towards them and returning the highest scoring ones.</P>
+
+<P>If we look at the problem from a mathematical perspective, a <B>user-item-matrix</B> is created from the preference data and the task is to predict the missing entries by finding patterns in the known entries.</P>
+
+<H3><A name="ItembasedCollaborativeFiltering-ItembasedCollaborativeFiltering"></A>Itembased Collaborative Filtering</H3>
+
+<P>A popular approach called "Itembased Collaborative Filtering" estimates a user's preference towards an item by looking at his/her preferences towards similar items, be aware that similarity must be thought of as similarity of rating behaviour not similarity of content in this context.</P>
+
+<P>The standard procedure is to pairwisely compare the columns of the user-item-matrix (the item-vectors) using a similarity measure like pearson-correlation, cosine or loglikelihood to obtain similar items and use those together with the user's ratings to predict his/her preference towards unknown items.</P>
+
+
+<H3><A name="ItembasedCollaborativeFiltering-Map%2FReduceimplementations"></A>Map/Reduce implementations</H3>
+
+<P>Mahout offers two Map/Reduce jobs aimed to support Itembased Collaborative Filtering.</P>
+
+<P><B>org.apache.mahout.cf.taste.hadoop.similarity.item.ItemSimilarityJob</B> computes all similar items. It expects a .csv file with the preference data as input, where each line represents a single preference in the form <EM>userID,itemID,value</EM> and outputs pairs of itemIDs with their associated similarity value.</P>
