<span>用户不断变化的行为信息，如果存在上帝，每一个人的行为都在时刻被上帝那双无形的眼睛监控着，广义上讲，一个用户打开网页，买了一个杯子；与该用户傍晚溜了趟狗，白天取了一次钱，打了一个哈欠等等一样都是上帝眼中的用户行为。当行为集中到互联网，乃至电商，用户行为就会聚焦很多，如上图所示：浏览凡客首页、浏览休闲鞋单品页、搜索帆布鞋、发表关于鞋品质的微博、赞“双十一大促给力”的微博消息。等等均可看作互联网用户行为。</span>

<span>什么用户：关键在于对用户的标识，用户标识的目的是为了区分用户、单点定位。</span>

<span>什么时间：时间包括两个重要信息，时间戳+时间长度。时间戳，为了标识用户行为的时间点，如，1395121950（精度到秒），1395121950.083612（精度到微秒），通常采用精度到秒的时间戳即可。因为微秒的时间戳精度并不可靠。浏览器时间精度，准确度最多也只能到毫秒。时间长度，为了标识用户在某一页面的停留时间。</span>

<span>什么地点：用户接触点，Touch Point。对于每个用户接触点。潜在包含了两层信息：网址 + 内容。</span>

<span>什么事：用户行为类型，对于电商有如下典型行为：浏览、添加购物车、搜索、评论、购买、点击赞、收藏 等等。</span>

<span>标签，表征了内容，用户对该内容有兴趣、偏好、需求等等。</span>

<span>权重，表征了指数，用户的兴趣、偏好指数，也可能表征用户的需求度，可以简单的理解为可信度，概率。</span>
