Abstract: An example method includes receiving queries from devices that include respective samples of content from a stream of content rendered by a source, receiving samples of content from a stream of content rendered by an alternative feed of the source, and for each sample of content from the alternative feed of the source, identifying respective matching queries that match to the same content as the sample of content from the alternative feed of the source. The method also includes for each respective matching query, determining a respective relative time difference between a time that the content appears in the sample of content from the alternative feed and a time that the content appears in the respective matching query, accumulating a distribution of the time differences over time, and determining a latency between the source and the alternative feed of the source.

Abstract: Methods and systems for arranging and searching a database of media content recordings are provided. In one example, a method is provided that comprises receiving a sample of media content, and performing, by a computing device, a content recognition of the sample of media content using a data file including a concatenation of representations for each of a plurality of media content recordings. In other examples, another method is provided that comprises receiving media content recordings, determining a representation for each media content recording, concatenating by a computing device the representation for each media content recording as a data file, and storing by the computing device a mapping between an identifier for a respective media content recording and a global position in the data file that corresponds to the representation of the respective media content recording.

Abstract: Methods and systems for performing content recognition for a surge of incoming recognition queries are provided. Within examples, methods comprise receiving, by one or more computing devices, a stream of incoming content recognition queries, and a given content recognition query includes a sample of media content and a request to identify the sample of media content. Methods also comprise filtering, by the one or more computing devices, a plurality of content recognition queries from the stream of incoming content recognition queries belonging to a surge event, and the surge event is associated with content recognition queries received within a time window and including common samples of media content.

Abstract: A set of criteria is acquired that defines a category of entities. The set of criteria is dynamically applied to identify an entity that meets the criteria. It is determined that the entity is registered as having control over at least a portion of a World-Wide Web address. The at least a portion of a World-Wide Web address is associated with the entity in a presentation that indicates that the entity belongs to the category of entities. In the presentation, a link may be included to a set of computer data about the entity. The set of computer data includes information other than information provided at a World-Wide Web site corresponding to the World-Wide Web address.

Abstract: It is determined that an entity is registered as having control over the use of at least a portion of a World-Wide Web address for a first set of computer data that is accessible in accordance with Internet protocols. Enhanced search results are acquired that include a second set of computer data. The second set of computer data includes or links to information pertaining to the entity, other than information provided at the Web address.
