....of one protocol. In both systems contexts are required to be inherently symbolic (discrete) as opposed to originally continuousvalued factors such as drug dosages crudely abstracted to simplify context sensitization. Integration of Predated Data Russ s Temporal Control Structure (TCS) Russ 86, Russ 90] is a framework for handling information that arrives out of chronological order. Beside maintaining conventional notions of systems (called modules) and input and output, TCS introduces history variables passing information forward in time to affect future decisions and oracle variables passing ....

....temporal abstraction, information visualization, and knowledge acquisition. Several approaches have been applied to the task of abstraction of time oriented data into higher level concepts, especially in medical domains, in which both large amounts of data and considerable knowledge are available [9, 10, 13, 15, 16, 19, 28]. None of these approaches, however, emphasized the need for a formal representation that facilitates acquisition, maintenance, sharing, and reuse of the required temporal abstraction knowledge; this emphasis is the focus of our previous and current research. Furthermore, previous ....

....Tuesday arrives today) Thus, the past can change our view of the present. This phenomenon has been called a view update [7] Furthermore, new data should enable us to reflect on the past; thus, the present (or future) can change our interpretation of the past, a property referred to as hindsight [8]. 4. Several possible interpretations of the data might be reasonable, each depending on additional factors that are perhaps unknown at the time (such as whether the patient has AIDS) interpretation should be specific to the context in which it is applied. All reasonable interpretations of the ....

....enables the TA mechanisms to focus on the abstractions appropriate for particular contexts, such as potential consequences of a certain event, and to avoid unnecessary computations in other contexts. In addition, the ability to create dynamically retrospective contexts enables a form of hindsight [14], since the interpretation of present data can induce new interpretation contexts for the past and thus shed new light on old data. Note that the representations of both hindsight and foresight are outside of the scope of formalisms intended for projection or simulation tasks, such as the event ....

....maintenance. For example raw data may well be received out of temporal sequence. Thus abstractions referring to the present may need to be modified on the basis of old data that has now become available (view updating [152] or abstractions referring to the past are revoked by new data (hindsight [141]) 2.3 Integration of data abstraction into a problem solving system Data abstraction is a critical auxiliary process. It is deployed in the context of a higher level problem solving system, it is knowledge based and it operates under a goal or event driven fashion or both. The knowledge used by ....

....the potentially troublesome formation of new contexts [30] Thus, the past can change our view of the present. Furthermore, new data enable the RSUM system to modify past interpretations; thus, the present (or future) can change our interpretation of the past, a property referred to as hindsight [27]. The hindsight task is performed by several components of the RSUM systems architecture: 1) the truth maintenance system; 2) the context forming mechanism, which can create both prospective and retrospective contexts dynamically; and (3) the temporal interpolation mechanism, which has the ....

TR has been applied in planning systems [8, 106, 92, 5] natural language understanding [120, 15, 17, 44] or expert systems [59, 31, 11, 88, 58, 94, 95], to cite few of them. A set of ontological and representational issues has to be considered in defining a TR system. The rest of this article is devoted to presenting and analysing them.

....of propagating information and using the automatic updating facilities has been applied in the areas of cardiac intensive care and the management of acute diabetic ketoacidosis. The TCS is specifically designed to allow information to arrive out of order, and for previous information to be changed [Russ90]. These particular attributes are not needed for processing the Symposium data set, since all of the information arrives quickly and in order. The TCS approach differs from other signal processing approaches such as VM [Fagan80] and blackboard architectures [Nii82] in that the data dependencies ....
