Abstract: 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.

Abstract: Contextual or cumulative interpretation is applied to individual user queries to improve the accuracy of sponsored and/or non-sponsored search results. Queries are interpreted based on present features derived from a user query in the context of past features derived from qualified past queries such as those previously received during a user query session. Based on contextual interpretation, present features may be augmented using past features. A search is performed using augmented features instead of present features. Contextual interpretation of queries improves search system understanding of the context in which queries are submitted, which is particularly helpful when interpolating query intent to develop features not expressed in a query. Contextual interpretation permits queries to be interpreted and treated more uniformly and more intelligently. As a result, users and advertisers benefit from more precise sponsored and/or non-sponsored search results.

Abstract: A structured file includes information to bind a web data source to a web data query system. Code is embedded within the structured file and is in a code language understood by the web data query system. The code is unrestricted in function. Code language objects are exposed within the web data query system for use by the code to interface with the web data query system and the web data source. A URL is associated with the structured file to enable access of the structured file through the Internet. A unit-based quota method is implemented to manage execution of code in the structured file. The unit-based quota method collapses multiple dimensions of computing resource control into a single unit value, tracks a number of units expended by the code, and stops execution of the code when the number of units expended by the code reaches a set limit.
