Exploiting program guides for contextualisation

Archives of cultural heritage organisations typically consist of collections in various formats (e.g. photos, video, texts) that are inherently related. Often, such disconnected collections represent value in itself but effectuating links between 'core' and 'context' collection items in various levels of granularity could result in a 'one-plus-one-makes-three' scenario both from a contextualisation perspective (public presentations, research) and access perspective. A key issue is the identification of contextual objects that can be associated with objects in the core collections, or the other way around. Traditionally, such associations have been created manually. For most organizations however, this approach does not scale. In this paper, we describe a case in which a semi-automatic approach was employed to create contextual links between television broadcast schedules in program guides (context collection) and the programs in the archive (core collection) of a large audiovisual heritage organisation
