Integrated MSS effects: An empirical health care investigation

Since accurate decisions are required for effective management, much research has focused on information systems that support decision making. Recently, this research has engendered frameworks, such as the management support system (MSS), that are designed to provide comprehensive and integrated support for the decision making process. Few, if any, studies have empirically measured the effects of these frameworks on decision making. This article offers empirical evidence on MSS effectiveness. It overviews the decision making process, presents an MSS for supporting the process, and assesses the influences of the MSS on the process and outcomes of health care decision making. The paper also examines the implications of the analyses for information systems research and health care practice.     

Optimization of some factors affecting the performance of query expansion

This paper examines the factors affecting the performance of global query expansion based on term co-occurrence data and suggests a way to maximize the retrieval effectiveness. Major parameters to be optimized through experiments are term similarity measure and the weighting scheme of additional terms. The evaluation of four similarity measures tested in query expansion reveal that mutual information and Yule's Y, which emphasize low frequency terms, achieve better performance than cosine and Jaccard coefficients that have the reverse tendency. In the evaluation of three weighting schemes, similarity weight performs well only with short queries, whereas fixed weights of approximately 0.5 and similarity rank weights were effective with queries of any length. Furthermore, the optimal similarity rank weight achieving the best overall performance seems to be the least affected by test collections and the number of additional terms. For the efficiency of retrieval, the number of additional terms needs not exceed 70 in our test collections, but the optimal number may vary according to the characteristics of the similarity measure employed.

承德农业生态系统分析

承德市农业生态系统尚未摆脱传统农业模式,无偿利用的环境资源能值较高,经营粗放,生产效率不高,但生产潜力巨大。承德农业生态系统的表土损失率不高,比河北其它各市的土壤保持价值量都要大,这对于作为京津水源供应地和生态屏障地来说,则具有非常重要的意义。     

基于Vague相似度量理论的园林喷灌设计方案评价方法

在描述Vague之间的相似度量与加权相似度量方法的基础上,提出了方案评价所采用的评价指标体系,形成了一套喷灌设计方案评价新方法.在园林喷灌设计方案评价中,Vague集之间的相似度量是评价设计方案接近期望方案（理想方案）的度量,相似度量值越大,设计方案接近期望方案越好.通过实例阐明Vague集之间的相似度量在喷灌设计方案评价中的可行性,方案评价取得了较为满意的结果.
