On fortune telling for health informatics.

This paper examines the paper of Haux et al. in this issue of this journal. It gives some background on specifics of the German health care system, which underlie the theses and prognoses proposed by Haux et al. In analogy to a forecast of the future of health informatics, which is now 10 years old, I then suggest that these attempts meet two types of challenges:that of overestimating the positive effects of recent advances, which later are found not to scale up; and that of blind spots with respect to unforeseen significant advances. The attempt to find indications of such in the projections of Haux et al. leads, among other, to the conclusion that the projections of direct linkages between patients and care providers may be overoptimistic. As to whether the deviating opinions matter in the end, it is concluded that the technology advances may require less attention that the restructuring of the health care system required to take advantage of the advances of technology.

A new approach to the concept of "relevance" in information retrieval (IR).

The concept of "relevance" is the fundamental concept of information science in general and information retrieval, in particular. Although "relevance" is extensively used in evaluation of information retrieval, there are considerable problems associated with reaching an agreement on its definition, meaning, evaluation, and application in information retrieval. There are a number of different views on "relevance" and its use for evaluation. Based on a review of the literature the main problems associated with the concept of "relevance" in information retrieval are identified. The authors argue that the proposal for the solution of the problems can be based on the conceptual IR framework built using a systems analytic approach to IR. Using this framework different kinds of "relevance" relationships in the IR process are identified, and a methodology for evaluation of "relevance" based on methods of semantics capturing and comparison is proposed.

A quantitative perspective on the virtual patient record (VPR) and its realization.

The Virtual Patient Record (VPR), the union of all collections of health relevant data that accumulates over a person's lifetime in any institution that person has contact with, is a technical possibility in the age of networked computers[1]. This paper investigates, under what conditions the VPR may be useful and manageable. Quantitative considerations of the VPR for a population of 10 M people form the basis. Dynamic aspects of updating and decay in value for treatment decisions are also taken into account. The role of centralized and distributed data stores are compared and the need for indexing is identified.

A structured model for evaluation of information retrieval (IR).

The paper reviews methods of evaluation of information retrieval (IR), in particular relevance (recall and precision) based approaches and their limitations and proposes a new model of IR which emphasizes the difference between the IR process and the technical IR system supporting the process. The model is proposed as basis for the structured evaluation of the IR process, and the planning, analysis and comparison of results of experiments using different methodologies.

Teaching medical informatics: teaching on the seams of disciplines, cultures, traditions.

This paper reviews different concepts of medical informatics and identifies two families of approaches to education in it: a "specialist" approach, whereby medical informatics is taught as a specialization track for established disciplines like medicine, computer science, nursing, engineering, etc., and a "generalistic" approach, whereby it is taught as an integrated discipline incorporating essential traits of the aforementioned disciplines. The pros and cons of these approaches are outlined. The need to accommodate specific requirements of education is emphasized and these are identified, together with an outline of particular challenges that we are facing.
