基于多相似性度量和集合编码的属性对齐方法

属性对齐的目标是发现异构知识图谱中表示同一概念的属性之间的对应关系,是实现跨图谱知识融合的关键技术之一。现有模型通常利用基于规则和词嵌入的方法进行属性对齐,但这些方法仍存在以下两个问题:相似性度量不全面和属性实例信息未被充分利用。针对上述问题,该文提出了基于多相似性度量的属性对齐模型,通过多个角度设计相似性度量方法来获取属性间的相似性特征,并利用机器学习模型进行特征聚合。同时,为了充分利用属性的实例信息,在上述模型框架下提出了属性实例集合表示学习算法,通过将属性实例集合编码为向量来提取集合间的主题相似性,从而辅助属性对齐。在属性对齐数据集上的实验验证了模型的有效性,实验还表明,集合的表示学习算法能够有效捕捉属性实例的主题特征,并显著提升属性对齐结果。

基于一阶逻辑的RDF模型的研究

XML为互联网应用提供了语法互操作性统一标准,而资源描述框架RDF定义了支持语义互操作的框架模型。作为RDF数据模型的类型系统,资源描述框架模式RDFS定义了一套扩充新的建模原语及其语义约束的机制。由于整个互联网语义化过程都以RDF模型为底层的模型支持,RDF数据模型及其类型系统的形式化程度直接影响和制约着更高层次上的语言和模型的形式化能力和推理能力。文章首先对RDFS类型系统做了非形式化分析,然后基于一阶逻辑定义了一套RDFS类型系统中对应类层次模型、类-实例模型和核心概念约束模型的事实-规则集。

针对传统面貌相似性度量方法容易受主观影响以及半自动面貌特征点提取方法存在标定不准确等问题，提出一种基于自适应邻域特征描述子的三维面貌相似性度量的方法。该方法将待比较面貌模型统一到法兰克福坐标系下，并利用等测地线方法根据面貌模型侧面轮廓线自动提取特征点；通过构建特征点的自适应邻域几何特征协方差矩阵，作为特征点描述子；对特征点的特征描述子进行相似性度量从而确定面貌模型间的相似性。实验结果表明，该方法不仅可以有效地评判三维面貌模型的相似性，而且能够区分相似面貌和不相似面貌模型。     

基于特征隶属度的文本分类相似性度量方法

基于相似性进行文本分类是当前流行的文本处理方法。基于特征隶属度的文本分类相似性度量方法旨在利用特征与文档间的隶属关系度量文档相似性,从而实现文本分类。该方法基于特征与文档的隶属关系,对特征进行全隶属、偏隶属和无隶属词集划分,并基于3种隶属词集定义隶属度函数。全隶属词集隶属于两篇文档,隶属度随权差增大而降低;偏隶属词集仅隶属于其中某一篇文档,隶属度为一个定值;无隶属词集与两篇文档无隶属关系,隶属度为零。在度量相似性时,偏隶属关系高于全隶属关系。由于同类文档词集相近,异类文档词集差异明显,因此,基于特征与文档的隶属度进行相似性度量,可清晰界定词集与类别的隶属关系,提升分类精度。最后,采用数据集20-Newgroups和Reuters-21578对分类有效性进行验证,结果表明基于特征隶属度的相似性度量方法的性能优于目前流行的相似性度量方法。     

基于云模型重叠度的相似性度量

云模型相似性是用来度量同类概念不同语言值的多个云之间关联程度的方法,相似云及其度量分析方法的提出是对云模型理论的扩展。针对目前相似性度量方法中时间复杂度过高和结果不稳定等不足,提出了一种基于云模型重叠度的相似性度量算法。首先,根据云模型期望、熵、超熵三个数字特征,定义两个云模型的位置关系和逻辑关系;其次,利用两个云的位置和形状特性,计算得到它们间的重叠度;最后,结合云模型重叠度与相似度的关系,将云模型的相似性度量转化为相应重叠部分的定量化描述。通过对时间序列分类实例的应用,验证了该算法在保证结果稳定度和正确率的前提下,与目前时间消耗较低的云模型相似度计算方法(LICM)相比,计算复杂度降低了50%,表明该算法具有可行性和有效性。

Model-driven approach to enterprise interoperability at the technical service level

Enterprise Interoperability is the ability of enterprises to interoperate in order to achieve their business goals. Although the purpose of enterprise interoperability is determined at the business level, the use of technical (IT) services to support business services implies that interoperability solutions at both the business and technical level should be aligned. This paper introduces and demonstrates the suitability of an approach based on model transformations to automate enterprise interoperability. We start by considering that a set of enterprises are willing to interoperate in the context of their individual goals. The interactions necessary for their cooperation are then properly captured in terms of a so-called choreography. Our approach allows a choreography to be mapped and transformed to an orchestration, which defines the operation of the actual technical services of the interoperating enterprises. The paper discusses the technical challenges of implementing the transformation, and illustrates our approach with two application scenarios.     

A federated approach to develop enterprise interoperability

Interoperability is one of the requisite features for existing enterprises in the increasing competitive and complex global market. In the last decade, enterprise interoperability has been developed and prescribed by various kinds of frameworks, methods, and techniques. However interoperability development is still not mature enough to become a science. Meanwhile, it keeps evolving according to different business requirement and market environment. Nowadays, networked environment causes unpredictable dynamical situations, thus sustainable interoperability becomes a new research dimension in the interoperability of enterprise systems and applications domain. In the sustainable interoperability, enterprise interoperability dynamics is one of the focal topics. This dynamic approach also called federated is originated from Enterprise Interoperability Framework of INTEROP NoE, which aims to establish interoperability on the fly. This paper presents current state on federated approaches to develop enterprise interoperability dynamics. Based on this study, a novel Federated interoperability approach is proposed. It aims at bridging the gap from interoperability concepts to the implementation of interoperable enterprise information systems development. This approach reuses distributed simulation interoperability concepts to facilitate and coordinate the communication between heterogeneous distributed information systems of the enterprises. This simulation part has been implemented into a software platform. This platform is complaint with the latest version of the high level architecture that is a distributed communication standard. This approach also proposes a development lifecycle that intends to reuse existing information systems without recoding them but by adapting them to the new requirements of interoperability dynamics.     

An approach for business process model registration based on ISO/IEC 19763-5

To facilitate business collaboration and interoperation among enterprises, it is critical to discover and reuse appropriate business processes modeled in different languages and stored in different repositories. However, the formats of business process models are very different, which makes it a challenge to fuse them in a unified way without changing their original representations and semantics. To solve this problem, this paper uses semantic interoperability technique which is able to transform heterogeneous process models into uniform registered items. Based on the general and unambiguous metamodel for process model registration (PMR for short) in ISO/IEC 19763-5 that we proposed before, in this article, we provide a generic process model registration framework for registering heterogeneous business process models to facilitate semantic discovery of business processes across enterprises, and promote process interoperation and business collaboration. Considering that Event-driven Process Chain (EPC) is a popular process model widely used in the industry, we focus on the mapping rules and related specific transformation algorithms from EPC to PMR as an instantiation of our framework and develop an automatic process model registration tool for EPC. Moreover, we conduct a series of experiments to verify the correctness and efficiency of our proposed framework by leveraging the real data set of 604 EPCs from SAP.     

Sustainable interoperability on space mission feasibility studies

The evolution of ICT towards fast and robust data exchange promoted the blooming of successful technical and business concepts like cloud computing and virtualisation of enterprise assets. The escalation of service providers enabled the specialisation of enterprises (particularly SMEs) and the building of provider networks. This move from enterprise-concentric to service-dispersed strategies is leading to concerns about reaching and maintaining the interoperability between customer–provider pairs and their associated business networks. This is particularly true in the aerospace industry: a highly-competitive and demanding business supported by numerous applications, which may be general-purposed, specific, proprietary or open-sourced, all needing to be interoperable with the lowest impact on the business itself. This paper addresses the need for improving the sustainability of enterprise interoperability via the application of negotiations, with the objective of reducing the impact of changes and achieving the best solutions in the interoperability between the enterprises and their surrounding environment. It proposes a framework that features a negotiation mechanism for the management of changes towards the sustainability of the seamless business-to-business interactions, and describes its application on the real business case of the ESA-CDF space mission feasibility studies.     

NEGOSEIO: A framework for negotiations toward Sustainable Enterprise Interoperability

With the rise of the Internet, competitiveness is pressuring enterprises to build better solutions with fewer resources, following new trends and supporting new platforms and methodologies. On the other hand, legislation and regulations are updating frequently and deeply, and demanding rapid compliance from enterprises. These frequent business changes shake all the interoperability links between the enterprises, leading to periods of adaptation where business operation is not possible. The urge to rapidly regain interoperability often leads to unfounded, poorly-chosen solutions, which lead to inefficiency and rework. This paper proposes that the best way to have a strong interoperable environment is to perform constant, periodic maintenance operations in order to adapt enterprises to their surrounding ecosystem. It introduces NEGOSEIO, a framework that promotes continuous improvement and adaptation towards the management of interoperability on enterprise systems, and which has negotiations as a core mechanism to handle inconsistencies and solutions for the detected interoperability problems. Following this approach, enterprises shall become more adaptable to changes and external factors, consequently developing resilient and efficient interactions with its supply chain. The paper validates the framework with its application in a real business case of aerospace mission design on the European Space Agency (ESA).     

Sustaining interoperability of networked liquid-sensing enterprises: A complex systems perspective

The emerging Liquid-Sensing Enterprise (LSE) concept provides manufacturing industrial networks with the required enablers to seamless interoperate and sustain its interoperability along the operational life cycle. Actually, the actual domain of enterprise information systems interoperability prospects the need for a new paradigm able to manage the network dynamics, facilitating adaptation along the lifecycle of an enterprise and the LSE network. The theory of complex systems provides a set of heuristics that can be applied to support the formalization of the LSE industrial network and its dynamics, demonstrating how they can be enabled and at the same time controlled to keep the overall level of interoperability stable. Hence, today there is technology suitable to implement such systems, capable to realize the LSE real, digital and virtual worlds. However, isolated, this technology cannot deliver the requirements for a self-sustainable LSE network. The authors propose a novel metaphor from complexity as a framework to model and implement the mechanism for sustaining interoperability in such networked environments. They identify the motivations for sustaining interoperability of networked liquid-sensing enterprises, having complex and adaptive systems as a vehicle to model and understand the relationships between enterprises and enterprise information systems in networked environments. Then, existing technology such as model-driven interoperability, agent-based or service oriented architectures, and knowledge management, is proposed to detail the conceptual solution for the sustainability of interoperability. An instantiation of the concept proposed is presented, which details the prototypal application elaborated in a real manufacturing scenario, implemented and validated during the European Project Factories of the Future IMAGINE.     

Toward a business model reference for interoperability services

The importance of interoperability for businesses is undoubted. After an evolution from electronic data interchange to interoperability in electronic business and enterprise interoperability both the scientific and the practitioners’ community are today discussing the notion of interoperability service utilities. Furthermore, researchers are studying decentralized and distributed interoperability approaches such as peer-to-peer networks, for example. However, a comprehensive investigation of business models for such decentralized approaches to interoperability is still missing. Drawing from recent literature on business modeling on the one hand and interoperability research on the other hand this paper designs a business model reference for interoperability services. The business model reference assumes interoperability information as an economic good and is applied in two case studies and evaluated from multiple perspectives. The paper contributes to the scientific body of knowledge as it proposes a novel design artifact which lays the foundation for a number of future research opportunities.     

A novel rule-centric object oriented approach for document generation

Complex business models in large-scale enterprises deal with voluminous knowledge based on which most decisive official and technical documents are generated. Nowadays, template processors are available for generating such documents. However, the existing template processors are either labor intensive or complicated to suit well-established business model and knowledge repositories in a heterogeneous environment. Hence, a novel generalized adaptable and flexible template processor that utilizes the existing resources without modifying the business model is proposed. The tacit business intelligence defined as rules, knowledge repositories and document structure are the nodal agents of this approach. Further, an XML based Object Query Definition Markup Language for rule definition is newly suggested. The rules are reorganized into hierarchical DAG structured rules using a transformation algorithm and traversed using hybrid traversal. The required output document is represented through a template. Object wrappers act as the communicating agent between diversified datasets and the templates. The proposed architecture is modeled and implemented using set theory. It is experimented in a web-based distributed environment using JAVA and tested using a real world dataset of a large-scale engineering enterprise. The results demonstrate its adaptability and extensibility to any multi-organizational structure.
