使用事件值資料記錄多個項目互動事件

下列範例顯示如何記錄具有不同事件類型和不同事件值的多個項目互動事件。

當您設定解決方案時，如果您的項目互動資料集包含 EVENT_TYPE 和 EVENT_VALUE 欄位，您可以將特定值設定為閾值，從訓練中排除記錄。如需詳細資訊，請參閱 選擇用於訓練的項目互動資料。

此範例也會顯示額外屬性的記錄numRatings，該屬性可用作特定配方的中繼資料。

Dataset columns: USER_ID, ITEM_ID, TIMESTAMP, EVENT_TYPE, EVENT_VALUE, NUM_RATINGS
Item interactions dataset: user123, movie_xyz, 1543531139, rating, 5, 12
                      user321, choc-ghana, 1543531760, like, 4
                      user111, choc-fake, 1543557118, like, 3

Python

personalize_events = boto3.client(service_name='personalize-events')

personalize_events.put_events(
    trackingId = 'tracking_id',
    userId= 'user555',
    sessionId = 'session1',
    eventList = [{
        'eventId': 'event1',

注意

屬性機碼使用與「互動」結構描述中的欄位相符的小寫連字 (camel case) 名稱。例如，如果在交互結構描述中定義了字段 'NUM_RATES'，則屬性鍵應該是。numRatings
