A mechanism is provided for cross-linking information sources using multiple modalities. Text documents, images, audio sources, video, and other media are analyzed to determine media descriptors, which are metadata describing the content of the media sources. The media descriptors from all modalities are collated and cross-linked. A query processing and presentation module, which receives queries and presents results, may also be provided. A query may consist of textual keywords from user input. Alternatively, a query may derive from a media source, such as a text document, image, audio source, or video source.
