Abstract

The present invention provides a system and method for navigating through source content to identify a desired feature within the source content, semantic source metadata being associated with portions of the source content. The system includes an input interface for receiving a request for the desired feature, and a processing unit for generating from the request a search request specifying the desired feature with reference to semantic metadata, and for causing the search request to be processed to identify semantic source metadata indicative of the desired feature. An output interface is provided for outputting as the desired feature a representation of the portion of the source content associated with the identified semantic source metadata. This provides an accurate and efficient technique for finding particular features within the source content.
