Categorizing items
We don't recommend creating too many channel/category for your inventory. For instance, if you have 10000 items and have 5000 categories with at least 1 item on each category, then asking for a recommendation only for a specific category may not return any results if the specific category has no user activity.
Sometimes you may want to restrict recommendation to a specific category that you've defined. For example, you might want to recommend news article for specific section and videos on some other pages. You can define a field called channel to specify the broad category of the item.
Elaborating from the mentioned example, sample query below will return items that are marked with specified channel value:
$p('register', {
max: 50, // Large number requested so you can see our full range of items
widget: 'default-widget', // name of widget
opts: {channel: "videos"}, // Return items that have value "videos" on channel.
callback: function (resp) {
console.log(JSON.stringify(resp, null, 2));
}
});
$p('fetch’);
To setup the channel scraping for each web page, please refer to Inventory section of documentation.
