Techniques for generating automated tags for a video file are described. The method includes receiving one or more manually generated tags associated with a video file, based at least in part on the one or more manually entered tags, determining a preliminary category for the video file, and based on the preliminary category, generating a targeted transcript of the video file, wherein the targeted transcript includes a plurality of words. The method further includes generating an ontology of the plurality of words based on the targeted transcript, ranking the plurality of words in the ontology based on a plurality of scoring factors, and based on the ranking of the plurality of words, generating one or more automated tags associated with the video file.

Methods and systems for coordinating provisions of storage service for clients are provided. For each storage provider of a set of storage providers, a service-provider database stores a metric characterizing a property of a service provided by the service provider. The storage providers are independently owned and operated relative to each other. The metrics are repeatedly updated. A selection engine repeatedly selects a service provider from the set of service providers to store a content object of a client of the content delivery system. The selection is based on the repeatedly updated metrics for the set of service providers. For each service provider selected by the selection engine to store the content object of the client, a service manager coordinates with the service provider such that the service provider stores the content object of the client.

Targeted and dynamic content-object storage based on inter-network performance metrics

Various embodiments of the present invention include concept-service components of content-search-service systems which employ ontologies and vocabularies prepared for particular categories of content at particular times in order to score transcripts prepared from content items to enable a search-service component of a content-search-service system to assign estimates of the relatedness of portions of a content item to search criteria in order to render search results to clients of the content-search-service system. The concept-service component processes a search request to generate lists of related terms, and then employs the lists of related terms to process transcripts in order to score transcripts based on information contained in the ontologies.

A method and system for tracking visitors' access to web content using a searchable and size-constrained local log repository is disclosed. A repository indexer receives visitor logs from a remote source and indexes the logs to include a usage field indicating when or how frequently an associated visitor log was accessed from a local log repository by a report request manager. The local log repository stores the logs and is size constrained. A repository manager removes a subset of the logs in the local log repository based on parameters within the subset of the logs' usage field. The report request manager receives a request from a requestor for a report indicating visitors' access to a content object, searches for logs within the local log repository pertinent to the request, aggregates data across the logs responsive to the search, and generates a report presenting the aggregated data.

Methods and systems generate content-categorization hierarchies and assign each content object to a set of nodes in the hierarchies. Each hierarchy includes a series of levels, each level including nodes which represent a categorization. A node in a top level is connected with multiple nodes in a lower level via a direct path. Each content object is assigned to a set of nodes, such that assignment to a lower-level node also results in assignment to each higher-level node in the lower-level node's direct path to a top of the hierarchy. Metadata of the content object is then modified to include a set of tags, each tag being a term from an assigned node. Tags are used to categorize the content object, summarize of the content object, identify recommended content objects, identify content objects responsive to a search query, and/or identify other content objects to supplement the content object.

Methods and systems for performing top concepts extraction

A system and method, operable by a processor running on a computing device and stored on a tangible computer readable medium, the system and method creating continuous, fixed duration, fixed size, or other such playlists for use on an individual listener's portable music player, as a programming guide for an Internet radio station, or the like. Information can be drawn from a number of recommendation sources to help generate such playlists based on a dictionary of terms. Recommendation sources are sources available via the internet or other published information that identify the order in which songs are presented or played, and which may be aggregated and processed into song sequence data that allows the instant system and method to utilize the experience, effort and musical expertise of others to generate a continuous playlist. Exemplary recommendation sources include, but are not limited to, published Disc Jockey ('DJ') playlists, radio (terrestrial, satellite or internet) station websites from which playlists can be extracted or derived, individual listener playlists, or the like.
