| 2 | Evaluating Group Formation in Virtual Communities显示文摘In this paper, we are interested in answering the following research question: 'Is it possible to form effective groups in virtual communities by exploiting trust information without significant overhead, similarly to real user communities?'In order to answer this question, instead of adopting the largely used approach of exploiting the opinions provided by all the users of the community(called global reputation), we propose to use a particular form of reputation, called local reputation. We also propose an algorithm for group formation able to implement the proposed procedure to form effective groups in virtual communities. Another interesting question is how to measure the effectiveness of groups in virtual communities. To this aim we introduce the index in a measure of the effectiveness of the group formation. We tested our algorithm by realizing some experimental trials on real data from the real world EPINIONS and CIAO communities, showing the significant advantages of our procedure w.r.t. another prominent approach based on traditional global reputation. | Giancarlo Fortino Antonio Liotta Fabrizio Messina Domenico Rosaci Giuseppe MLSarnè | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，4： | 0 |
| 3 | 老年人功能评估简表对死亡率和住院率的预测效能研究显示文摘目的生物-心理-社会衰弱与死亡风险增加和医疗卫生服务利用有关。本研究旨在评估老年人功能评估简表(Short Functional Geriatric Evaluation,SFGE)对老年人死亡率和住院率的预测效能。方法采用回顾性队列研究对参与意大利“老年人长寿!”项目的人群进行分析。共纳入8561名75岁以上的意大利社区居民,平均随访时间516.6 d。计算老年人死亡率、住院率、养老机构入住率和SFGE评估的衰弱程度并进行分析。SFGE评分中社会经济相关条目占40%。结果与健康老年人相比,衰弱前期、衰弱和非常衰弱老人死亡(RR分别为1.40、2.78和5.41)、住院(OR分别为1.31、1.67和2.08)和养老机构入住(OR分别为3.63、9.52和10.61)风险显著增加。在仅纳入社会经济条目的模型中得到类似结果。衰弱预测死亡率的受试者工作特征曲线下面积为0.70(95%CI 0.68~0.72),敏感性和特异性分别为83.2%和40.4%。结论SFGE评分通过对老年人衰弱程度进行分层来预测死亡、住院和养老机构入住风险。该评估工具简短、包含社会经济变量等特征使之可作为公众健康大样本筛查工具,将衰弱作为社区老年人照护的核心。 | Giuseppe Liotta Grazia Lorusso Olga Madaro Valeria Formosa Susanna Gentili Fabio Riccardi Stefano Orlando Paola Scarcella Leonardo Palombi | 2023 | International Journal of Nursing Sciences2023，10，1： | 0 |
