Media objects, such as images or soundtracks, may be ranked according to a new class of metrics known as “interestingness.” These rankings may be based at least in part on the quantity of user-entered metadata concerning the media object, the number of users who have assigned metadata to the media object, access patterns related to the media object, and/or a lapse of time related to the media object.

尝试翻译一下（注：如被误导，拒不负责）：

对媒质对象，例如图像或者录制的音乐，根据一种新的被称为“引起兴趣的”度量进行分级排序。这种方式至少部分基于媒质上的用户输入的元数据的数量，对媒质对象标记元数据的用户的数量，关于媒质对象的访问模式，并且/或者关于这个媒质对象的一段时间。
