Semantic Web: A road to the knowledge infrastructure on the internet

In this article, I describe the basic technologies for Semantic Web and relationship between Semantic Web and Knowledge Representation in Artificial Intelligence. Semantic Web is planned as an extension of the current web in order to help cooperation between computers and humans, i.e., computers and humans are expected to understand each other in the knowledge level. I first describe the vision of the Semantic Web, then introduce the current Semantic Web technologies, i.e., RDF, RDFS, and OWL. I describe relationship between the trend of Semantic Web and Knowledge Representation, and clarify challenges and difficulties of Semantic Web from the point of view of Knowledge Representation.

基于制造网格平台的模具制造资源共享机制研究

介绍了制造网格的基本概念，分析了中国模具制造企业制造资源利用现状以及对信息化的需求，提出了基于制造网格平台的模具制造资源共享机制。对中小模具企业里的各种与模具全生命周期有关的资源进行分类、规划和整合，以制造网格为平台构建了制造服务协同制造网络。通过对模具制造资源进行网格化封装，实现了资源的协同共享，为中国模具制造企业实现信息化和网格化制造提供了理论支撑。     

Multisecret-sharing schemes and bounded distance decoding of linear codes

Error-correcting codes are used to correct errors when messages are transmitted through a noisy communication channel. Bounded distance decoding (i.e. decoding up to the error-correcting capacity) is a method of correcting errors that guarantees unique decoding. Secret sharing is a cryptographic protocol that allows a secret known from a person called the dealer to be distributed to n participants. No single participant knows the secret but some special subsets of participants called coalitions can. In this paper, we present a multisecret-sharing scheme based on an error-correcting code where secret reconstruction is made by using bounded distance decoding of the code. This scheme is ideal in the sense that the size of each secret equals the size of any share. Its security improves on that of multisecret-sharing schemes.     

Exploring the role of the sharing economy in disasters management

Improvements in information and communications technologies (ICTs) have facilitated the inclusion of the sharing economy (SE) in societies more than ever. In the aftermath of recent disasters, the SE played significant roles to help the affected people and support official responders. However, the literature has not effectively explored these roles, and thus, no framework can support the systematic inclusion of the SE in disasters management. This paper aims to address the gap through a two-stage exploratory research approach. First, we conduct a systematic literature review to identify the extent to which the SE is taken into consideration in disasters. After that, we investigate the role of three Iranian SE-based companies that were involved in the 2019 Iran floods response. We collect empirical data by conducting semi-structured interviews and reviewing official reports.Our findings indicate that very few studies discuss the different roles of the SE in disasters, although SE companies have often provided effective solutions to address critical post-disaster logistics challenges. Four research propositions are presented to describe emerging roles for SE companies. The contribution of our study is twofold. First, our research identifies the different roles that the SE could play in disasters and therefore, brings a new perspective to the literature. Second, the study suggests opportunities for collaboration and partnership models from the point of origin to delivery that can support coordination and logistics in disasters.     

财务共享模式下的医院财务管理优化研究

大数据背景下,财务共享技术成为各行各业财务管理发展的新方向,为了验证财务共享技术应用于医院财务管理的优势,此次研究将设计出一种财务共享服务中心,并利用该共享服务中心优化医院财务管理流程,比较优化前后的财务管理各方面的差异。研究结果表明,基于财务共享模式的医院财务管理中,会计成本、报销成本、工资成本、资金预算成本依次降低55%、40%、35%、35%;客户满意度提升幅度为25%,后台运营成本降低了54%;会计核算效率和会计信息的信息准确度提高,漏报率与误报率降低。说明医院可通过财务共享模式的应用,提高医院财务管理效率,降低投入成本。希望本次研究的结果能为医院财务管理的发展提供参考。     

一种安全的门限群签名方案

门限签名是一类重要的数字签名,到目前为止,已有许多门限方案相继被提出,但它们都是不安全的,几乎都有弱点：当恶意成员大于或等于门限时,能以高概率获取系统秘密,并由此伪造群签名。在现有门限方案的基础上提出了一种比较安全的门限群签名方案,新方案较已有的方案性能更好,尤其是克服了已有方案的缺点。最后对新方案的安全性进行了讨论。     

一个完善的可公开验证秘密分享方案

利用离散对数问题的难解性和Williams体制,在假设初始化阶段和秘密恢复阶段始终有一位值得信赖的分发者参与的情况下,提出了一个可公开验证的门限秘密分享方案。在方案中,各用户只需公布其秘密份额的盲化值,每个参与者甚至第三者都可以对这一盲化的秘密份额进行验证;不但能有效地阻止密码分析者窃取秘密或子秘密,也能有效地防止内部成员之间的相互欺诈,而且任一分享者能在多项式时间内恢复密钥。
