Collecting Data</h2><p>Next, let&#39;s collect some training data for the app of this Engine. By default, the Similar Product Engine Template supports 2 types of entities: <strong>user</strong> and <strong>item</strong>, and event <strong>view</strong>. An item has the <strong>categories</strong> property, which is a list of category names (String). A user can view an item. Respectively, this template requires &#39;$set&#39; user event, &#39;$set&#39; item event, and user-view-item events.</p><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>.</p></div><p>You can send these events to PredictionIO Event Server in real-time easily by making a HTTP request or through the provided SDK.
