Designed for librarians, Question Master (QM) (at http://purl.org/net/Question_Master) is a decision-support system automating some of the more routine, fact-type reference questions encountered in libraries. A series of Web pages guides librarians through a set of clarifying questions before making recommendations of an appropriate electronic or relevant print resource from WorldCat, the OCLC Online Union Catalog. The goal is to improve the accuracy of reference transactions, which in turn should lead to increased end-user satisfaction. Based on usability studies of QM’s biographical module, this study found that although the system already was easy to use, its usability could be improved in several ways. Its ability to answer questions was 100 percent, with an accuracy rate of 66 percent compared to Weil’s 64 percent accuracy. In addition, QM accuracy was substantially better than most reported studies of real reference environments and certainly better than the Internet results of 20 percent for HotBot and 30 percent for AltaVista.

Smart Home Appliances

Researches in the field of ambient assisted living (AAL) have increased in the last ten years, and the paradigms of the smart home have widely spread. Smart homes must consider the health-related issues and the real needs deriving from the ageing of their dwellers. In the smart home, appliances are expected to provide support to the residents, especially when they are characterized by disabilities and/or impairments related to ageing. While most of the AAL solutions presented in literature rely on complex systems and architectures, residents affected by mild or moderate disabilities can take advantage of just a simpler reconfiguration of living environments, i.e., the replacement of certain appliances with others that are able to help them in coping with their limitations. This paper proposes a semantic-based decision support system (DSS), which relies on ontological models, to assist designers in domestic environments’ reconfiguration. The ontology leverages semantic representations of dwellers and domestic environments’ domains of knowledge to foster the adoption of appliances able to help the residents to live independently. The development process of the ontology is presented in detail together with the results deriving from reasoning processes. To ease the reconfiguration of domestic environments, a prototypical application taking advantage of the DSS is presented.

Gis Software

Geographic information systems are becoming more popular for end-user and decision support system construction, but they incorporate software and concepts with some inherent problems for users not trained in concepts of geography and cartography. This paper identifies those concepts most needed for end-user GIS use, and suggests remedial efforts to reduce the burden of system operation and improve data integrity. The approaches make extensive use of metadata storage and may be implemented as tools in GIS software provided to end-users.

BACKGROUND Computerized clinical decision support system is a solution to promote ATLS protocol for traumatic injuries. To study its design based on user requirements and usability, a Kano questionnaire research to survey perspectives of physicians was undergone. OBJECTIVE This study aims to elicit user requirements for a CDSS treating traumatic patients in a hospital setting and it’s usability by evaluating the features of TFA. METHODS We applied Kano mode research studying user requirements to further provide theoretical support for the development of the system. A 5-level questionnaire was designed based on the perspectives of Kano. The features of TFA were evaluated by pairs of questions: first a functional question and subsequently a dysfunctional question. The questionnaire along with system introduction and instructions were sent to the physicians in ED from five different hospitals that work as regional trauma centers and have ability to treat severe trauma patients. RESULTS A total of 63 physicians in ED responded the questionnaire completely and were concluded into the study including 16 physicians qualified with ATLS certificate and 47 having not passed the ATLS training. A total of 16 features were rated and classified using the Kano evaluation table. Five features are classified as indifferent (5/16, 31.3%), with five being one-dimensional (5/16, 31.3%), four being attractive (4/16, 25%) and two being must-be (2/16,12.5%). Both physicians with and without ATLS experience were indifferent to most of the evaluated features (11/16, 68.8%). A difference in user requirements between physicians with ATLS qualification and those without the qualification regarding 3,4,8,13,14 features. CONCLUSIONS The study provides recommendations to developers on the user requirements that need to be addressed when developing a CDSS for advanced trauma life support care in-hospital. Two features of must-be attributes must be incorporated in the TFA. In addition, four features (attractive attributes) would result in higher user satisfaction. Among those five one-dimensional features, ISS and knowledge database display high score in both positive and negative values that indicates developers to especially prioritize the features to be implemented when developing the CDSS.
