Abstract

A case study of a digital library that contains streams and supports event-based retrieval is described. Medical streams that relate to patients having liver tumors are used in the digital library. 3 types of streams were used: computed tomography (CT) scan, medical text, and audio streams. Events, such as ‘Maximum diameter of the tumor’, were generated and represented in the user interface to enable doctors to retrieve and playback segments of the streams. This paper presents the details of creating the digital library: the data organization, publishing stream data, generating the bibliographic metadata, using events, relating streams, the search engine, and the playback of the streams.
