The Ambient Spotlight: personal multimodal search without query

The Ambient Spotlight is a prototype system based on personal meeting capture using a laptop and a portable microphone array. The system automatically recognises and structures the meeting content using automatic speech recognition, topic segmentation and extractive summarisation. The recognised speech in the meeting is used to construct queries to automatically link meeting segments to other relevant material, both multimodal and textual. The interface to the system is constructed around a standard calendar interface, and it is integrated with the laptop's standard indexing, search and retrieval.
