Design and Implementation Issues in Longitudinal Research

Design and Implementation Issues

The early 1970s were a time of great optimism for researchers in the field of medical artificial intelligence. The initial successes of systems such as MYCIN, CASNET, and the Leeds abdominal pain system made it reasonable to assume that it was only a matter of time until computers became a standard part of physicians’ diagnostic armamentarium. Over the past few years, the emphasis in clinical d...

Design criteria , representational issues and implementation

This paper describes the design criteria and annotation guidelines of the Sinica Treebank. The three design criteria are: Maximal Resource Sharing, Minimal Structural Complexity, and Optimal Semantic Information. One of the important design decisions guided by these criteria is the encoding of thematic role information. We discuss the representational and methodological issues based on our desi...

Trajectory Data Warehouses: Design and Implementation Issues

In this paper we investigate some issues and solutions related to the design of a Data Warehouse (DW), storing several aggregate measures about trajectories of moving objects. First we discuss the loading phase of our DW which has to deal with overwhelming streams of trajectory observations, possibly produced at different rates, and arriving in an unpredictable and unbounded way. Then, we focus...

Design - based research – issues in connecting theory , research and practice

During the last 20 years, design-based research (DBR) has become a popular methodology for connecting educational theory, research and practice. The missing link between educational theory, research and educational practice is an ongoing issue and DBR is seen as an integrated methodology to bridge the gap. But is this as easy as it sounds? The purpose of the article is to identify and discuss i...
