The quality of the information provided by information services deployed in the EGEE production testbed differs from one system to another. Under the same conditions, the answers provided for the same query by different information services can be different. Developers of these services and of other services that are based on them must be aware of this fact and understand the capabilities and l...

Background & Aims: Compliance with standards of designing information systems leads to efficient utilization and ease of use for consumers. In this study, the compliance of the radiology and pathology subsystems of a hospital information system with ISO 9241 section 12 was assessed in selected hospitals affiliated with Kerman University of Medical Sciences, Iran. Methods...

Introduction: More and more patients are using the Internet to achieve information these days. Most patients (85%) use search engines to look for information about health. The quality of this information that patients encounter is highly different. This study aimed to assess the quality of information that an ear, nose, and throat patient would encounter when searching for information abo...

Information theoretic measures are of paramount importance in Bayesian inference. Yet, their direct application in practice has been somewhat limited by the severe computational diiculties encountered in complex problems. In this paper we discuss implementation strategies for fast numerical computations of Entropies and Kullback-Leibler divergences that are relevant to Bayesian inference and de...

This topic session focussed on a variety of issues in evaluation (three presentations) and extraction (on e presentation) . For the extraction presentation, Tsuyoshi Kitani, a visiting researcher at the Center fo r Machine Translation at Carnegie-Mellon University gave a presention entitled "Overview of TEXTRAC T Template-Filling Solutions" . This talk gave an overview of TEXTRACT, which proces...

Over its 40 year history information retrieval evaluation evolved with an emphasis on laboratory experimentation, the “Cranfield paradigm”, in response to early demands for experimental rigour. The current and highly successful TREC experiments follow this model. However the demand for results that are robust and scalable has caused an emphasis on system-centered evaluation at the expensive of ...
