摘要： Embodiments are directed towards multi-level entity classification. An object associated with an entity is received. In one embodiment the object comprises and email and the entity comprises the IP address of a sending email server. If the entity has already been classified, as indicated by an entity classification cache, then a corresponding action is taken on the object. However, if the entity has not been classified, the entity is submitted to a fast classifier for classification. A feature collector concurrently fetches available features, including fast features and full features. The fast classifier classifies the entity based on the fast features, storing the result in the entity classification cache. Subsequent objects associated with the entity are processed based on the cached result of the fast classifier. Then, a full classifier classifies the entity based on at least the full features, storing the result in the entity classification cache.
摘要翻译：实施例针对多级实体分类。接收与实体相关联的对象。在一个实施例中，对象包括和电子邮件，并且实体包括发送电子邮件服务器的IP地址。如果实体已经被分类，如实体分类缓存所示，则对对象采取相应的动作。但是，如果实体尚未分类，则将实体提交给快速分类器进行分类。功能收集器同时提取可用功能，包括快速功能和完整功能。快速分类器基于快速特征对实体进行分类，将结果存储在实体分类缓存中。基于快速分类器的缓存结果处理与实体相关联的后续对象。然后，完整分类器至少基于全部特征对实体进行分类，将结果存储在实体分类缓存中。
