Product Engine Template</h1></div></div><div class="content"> <h2 id='overview'
class='header-anchors'>Overview</h2><p>This engine template recommends products
that are "similar" to the input product(s). Similarity is not defined
by user or item attributes but by users' previous actions. By default, it
uses 'view' action such that product A and B are considered similar if
most users who view A also view B. The template can be customized to support
other action t
ypes such as buy, rate, like..etc.</p><p>This template is ideal for
recommending products to customers based on their recent actions. Using the IDs
of the recently viewed products of a customer as the <em>Query</em>, the engine
will predict other products that this customer may also like.</p><p>This
approach works perfectly for customers who are <strong>first-time
visitors</strong> or have not signed in. Recommendations are made dynamically
in <em>real-time</em> based on the most recent product preference you provide
in the <em>Query</em>. You can, therefore, recommend products to visitors
without knowing a long history about them.</p><p>You can also use this template
to build the popular feature of Amazon: <strong>"Customers Who Viewed This
Item Also Viewed..."</strong> quickly. Help your customers explore more
products that they like, and sell more products.</p><h2 id='usage'
class='header-anchors'>Usage</h2><h3 id='event-data-requirements'
class='header-anchors'>Event D
ata Requirements</h3><p>By default, this template takes the following data
from Event Server as Training Data:</p> <ul> <li>User <em>$set</em> events</li>
<li>Item <em>$set</em> events with <em>categories</em> properties</li>
<li>Users' <em>view</em> item events</li> </ul> <div class="alert-message
info"><p>This template can easily be customized to consider more user events
such as <em>buy</em>, <em>rate</em> and <em>like</em>. You can offer features
like "Customers Who Bought This Item Also Bought....".</p></div><h3
id='input-query' class='header-anchors'>Input Query</h3> <ul> <li>List of
ItemIDs, which are the targeted products</li> <li>N (number of items to be
recommended)</li> <li>List of white-listed item categories (optional)</li>
<li>List of white-listed ItemIds (optional)</li> <li>List of black-listed
ItemIds (optional)</li> </ul> <p>The template also supports black-list and
white-list. If a white-list is provided, the engine will include only those
products in
the recommendation. Likewise, if a black-list is provided, the engine will
exclude those products in the recommendation.</p><h3
id='output-predictedresult' class='header-anchors'>Output PredictedResult</h3>
<ul> <li>a ranked list of recommended itemIDs</li> </ul> <h2
id='1.-install-and-run-predictionio' class='header-anchors'>1. Install and Run
PredictionIO</h2> <p>First you need to <a href="/install">install PredictionIO
0.12.1</a> (if you haven't done it).</p><p>Let's say you have installed
PredictionIO at <code>/home/yourname/PredictionIO/</code>. For convenience, add
PredictionIO's binary command path to your <code>PATH</code>, i.e.
<code>/home/yourname/PredictionIO/bin</code>:</p><div class="highlight

Product Engine Template</h1></div></div><div class="content"> <h2 id='overview'
class='header-anchors'>Overview</h2><p>This engine template recommends products
that are "similar" to the input product(s). Similarity is not defined
by user or item attributes but by users' previous actions. By default, it
uses 'view' action such that product A and B are considered similar if
most users who view A also view B. The template can be customized to support
other action t
ypes such as buy, rate, like..etc.</p><p>This template is ideal for
recommending products to customers based on their recent actions. Using the IDs
of the recently viewed products of a customer as the <em>Query</em>, the engine
will predict other products that this customer may also like.</p><p>This
approach works perfectly for customers who are <strong>first-time
visitors</strong> or have not signed in. Recommendations are made dynamically
in <em>real-time</em> based on the most recent product preference you provide
in the <em>Query</em>. You can, therefore, recommend products to visitors
without knowing a long history about them.</p><p>You can also use this template
to build the popular feature of Amazon: <strong>"Customers Who Viewed This
Item Also Viewed..."</strong> quickly. Help your customers explore more
products that they like, and sell more products.</p><h2 id='usage'
class='header-anchors'>Usage</h2><h3 id='event-data-requirements'

ata Requirements</h3><p>By default, this template takes the following data
from Event Server as Training Data:</p> <ul> <li>User <em>$set</em> events</li>
<li>Item <em>$set</em> events with <em>categories</em> properties</li>
<li>Users' <em>view</em> item events</li> </ul> <div class="alert-message
info"><p>This template can easily be customized to consider more user events
such as <em>buy</em>, <em>rate</em> and <em>like</em>. You can offer features
like "Customers Who Bought This Item Also Bought....".</p></div><h3

recommended)</li> <li>List of white-listed item categories (optional)</li>
<li>List of white-listed ItemIds (optional)</li> <li>List of black-listed
ItemIds (optional)</li> </ul> <p>The template also supports black-list and
white-list. If a white-list is provided, the engine will include only those
products in
the recommendation. Likewise, if a black-list is provided, the engine will
exclude those products in the recommendation.</p><h3
