Managing Valid Time Semantics for Semistructured Multimedia Clinical Data
نویسندگان
چکیده
In this paper we propose an approach to manage in a correct way valid time semantics for semistructured temporal clinical information. In particular, we use a graph-based data model to represent radiological clinical data, focusing on the patient model of the well known DICOM standard, and define the set of (graphical) constraints needed to guarantee that the history of the given application domain is consistent.

A Temporal Data Model for Multimedia Database Systems
The presented data model is a novel approach for integrating temporal concepts into a multimedia database system. Multimedia objects are extended with the traditional time dimensions valid time and transaction time. In addition a new time dimension specifically tailored for multimedia data types is presented with semantics that are completely orthogonal to the already established time dimension...
متن کاملTrends in Managing Multimedia Semantics
This paper reviews various efforts to define and capture the semantics of multimedia data. These efforts are particularly relevant to the problem of storing, managing and querying the semantic content of such data. Since there is not yet an accepted solution to the problem of how to represent, organize and manage multimedia data and the related semantics by means of a formal framework, this pap...
متن کاملMaintaining Semantics in the Design of Valid and Reversible SemiStructured Views
Existing systems that support semistructured views do not maintain semantics during the process of designing views. Thus, there is no guarantee that the views obtained are valid and reversible views. In this paper, we propose an approach to designing valid and reversible semistructured views. We employ four types of view operators, namely, select, drop, join and swap operators, and develop a se...
متن کاملDesigning Valid XML Views
Existing systems for XML views only support selection operation applied in the views and cannot validate views. In this paper, we propose a systematic approach to design valid XML views. First, we transform the semistructured XML source documents into a semantically rich Object-RelationshipAttribute model designed for SemiStructured data (ORA-SS). Second, we enrich the ORA-SS diagram with seman...
متن کاملA Semantic Approach to the Design of Valid and Reversible Semistructured Views
Existing systems that support semistructured views do not maintain semantics during the process of designing the views. Thus, these systems do not guarantee the validity and reversibility of the views. In this paper, we propose an approach to address the issue of valid and reversible semistructured views. We design a set of view operators for designing semistructured views. These operators are ...
