A framework for historical case-based reasoning

This paper presents a framework for Historical Case-Based Reasoning (HCBR) which allows the expression of both relative and absolute temporal knowledge, representing case histories in the real world. The formalism is founded on a general temporal theory that accommodates both points and intervals as primitive time elements. A case history is formally defined as a collection of (time-independent) elemental cases, together with its corresponding temporal reference. Case history matching is two-fold, i.e., there are two similarity values need to be computed: the non-temporal similarity degree and the temporal similarity degree. On the one hand, based on elemental case matching, the non-temporal similarity degree between case histories is defined by means of computing the unions and intersections of the involved elemental cases. On the other hand, by means of the graphical presentation of temporal references, the temporal similarity degree in case history matching is transformed into conventional graph similarity measurement.

A small screen alternative to stone and bronze: The Great War series and British television

This article examines the first major British television series about the First World War, The Great War (BBC, 1964), in terms of its cultural, historical and aesthetic significance. As a central component of the BBC`s 50th anniversary commemorative programme to mark the outbreak of war, the series was a major media event -a small-screen memorial cast in sounds and images instead of stone and bronze. This article looks at how the British television audience responded to this form of on-screen commemoration. Material for this article was derived from the series' extensive production records housed in the BBC Written Archives Centre at Caversham, Berkshire. This was supplemented by, among other sources, material from interviews and correspondence with several surviving members of the production team. This allows a broader understanding of the motivations of those involved in the production of a groundbreaking historical series, while acknowledging the wide-ranging nature of its audience.
