以计算机为载体的电子病历系统以明显的优势取代传统的纸质病历,但是在电子病历系统建设的过程中,患者隐私安全也面临着新的挑战.患者隐私泄露使医患关系、以电子病历系统为代表的信息技术的权威,以及社会伦理都将面临危机.从哲学的视角看待隐私泄露问题,用哲学规制电子病历系统,通过技术提升、人员培训、法律完善、伦理构建来避免患者隐私泄露,从而保护患者个人权利. 相似文献

ABSTRACTAs service-oriented computing is commonly used in industrial systems to deal with the continually changing business environment, matching processes with existing services becomes one of the most important phases in constructing, integrating and optimizing information systems. The precision of semantic service matching becomes a critical factor in ensuring the correctness of functionalities in system processes. However, the dependability of semantic service matching cannot be warranted in complex contexts. To improve semantic service matching for industrial systems, a context-based semantic service matching approach named ‘Process-Based service MatchMaker’(PBMM) is proposed in this paper. It selects the suitable services for the process from candidate services through taking the dependencies of related services process into consideration. 相似文献

针对当前信息分类编码标准数量和所涉及领域不断增加的情况,文章提出了一个新的信息分类编码标准分类框架,以解决信息分类编码标准分类体系的完整性、稳定性和开放性等问题。它一方面在高层继承已有的标准分类体系,另一方面,参考借鉴现代汉语语义分类体系,在子领域部分设计出一个更为完整和稳定的框架结构。该分类框架能满足当前及今后信息分类编码标准的发展需求。 相似文献

It is difficult to predict the financial distress of unlisted public firms due to their longer disclosure cycle of accounting information and more inadequate continuity of market trading information compared to listed firms. In this paper, we propose a framework to predict the financial distress of unlisted public firms using current reports. Specifically, to better represent the meaning of current report texts, we propose a semantic feature extraction method based on a word embedding technology. Empirical results show that current reports contain more effective information for predicting the financial distress of unlisted public firms compared with periodic reports. In addition, semantic features extracted using our proposed method significantly improve the predictive performance, and their enhancing effect is superior to that of topic features and sentiment features. Our study also provides implications for stakeholders such as investors and creditors. 相似文献

The vision of the Semantic Web is to build a global Web of machine-readable data to be consumed by intelligent applications. As the first step to make this vision come true, the initiative of linked open data has fostered many novel applications aimed at improving data accessibility in the public Web. Comparably, the enterprise environment is so different from the public Web that most potentially usable business information originates in an unstructured form (typically in free text), which poses a challenge for the adoption of semantic technologies in the enterprise environment. Considering that the business information in a company is highly specific and centred around a set of commonly used concepts, this paper describes a pilot study to migrate the concept of linked data into the development of a domain-specific application, i.e. the vehicle repair support system. The set of commonly used concepts, including the part name of a car and the phenomenon term on the car repairing, are employed to build the linkage between data and documents distributed among different sources, leading to the fusion of documents and data across source boundaries. Then, we describe the approaches of semantic information retrieval to consume these linkages for value creation for companies. The experiments on two real-world data sets show that the proposed approaches outperform the best baseline 6.3–10.8% and 6.4–11.1% in terms of top five and top 10 precisions, respectively. We believe that our pilot study can serve as an important reference for the development of similar semantic applications in an enterprise environment. 相似文献
