Automatic localization of services at the time of logical modeling is a difficult task. This is because of the complexity of models and the scattered nature of enterprise architecture information in organizations, systems as well as actors and applications. However, all information about logical services is described in the eLEL and in the aspects of the business architecture of the Praxeme methodology...
The improvement in quality of services offered by educational institutions is one of the main challenges of the modern education informatics. The personalization of educational process requires adaptive learning schemes since the student status and conditions inside an institution constantly change. In this paper, we present the EDUC8 (EDUCATE) system, which aims at providing a new approach concerning...
Connecting different text attributes associated with the same entity (conflation) is important in business data analytics since it could help merge two different tables in a database to provide a more comprehensive profile of an entity. However, the conflation task is challenging because two text strings that describe the same entity could be quite different from each other for reasons such as misspelling...
The emergence of Systems of Systems (SoS) arrangements, with their high level of complexity, mainly due to the different characteristics of the individual systems and their integration into the respective SoS, has brought about new challenges in terms of Configuration Management (CM) in general, and change management in particular. Novel change management frameworks are needed to appropriately address...
We propose a data-centric three leveled modeling architecture in an effort towards a Model Driven approach of services for the Internet of Things (IoT): a resources level, an artifacts level and a semantic level. In this architecture, the resources level abstracts all important pieces of information describing real objects as resources. The artifacts level allows to collect all objects and contexts...
In this paper, we describe a real-time knowledge acquisition and anomaly handling architecture in a maintenance scenario of an industrial cyber-physical production environment. We use the Business Process Model and Notation (BPMN) for modeling and controlling of the maintenance procedure. Automatic handwriting and pen gesture recognition is combined with a networked smart pen that is used on semantically...
Business processes of large companies often lack the flexibility of their smaller competitors. This fact results in slower reaction to the changes in business environment which usually require to launch complicated IT projects. Nevertheless many tasks faced in these situations by IT departments have standard solutions which could be expressed in form of semi-formalized best practices and recommendations...
Business Process Model and Notation (BPMN), now at version 2.0.2, provides a standard graphical representation for specifying business processes. In this paper we report on the first stage of a semantic investigation of BPMN, using methods in the tradition of programming languages semantics. We consider a control-flow subset of BPMN and an execution architecture based on an intermediate language that...
In recent years there has been a huge discussion about the IoT (Internet of Things) concept, and even more about IoT within industrial environment. The real IoT is a network of devices with local intelligence (sensors, lights, gas pumps, HVAC systems), which shares access & control mechanisms to push and pull status and command information from the networked world. However, there are still some...
In large organisations different stakeholders are usually responsible for the management of business processes. This paper addresses the situation where multiple stakeholders with different interests are handling parts of the same business processes. One technique to support this are process views where each stakeholder holds a personal view which can be executed or changed. In this paper we investigated...
In recent years, the rapid growth of the Internet has greatly changed our way of sharing information. Internet brings both challenges and opportunities to modern enterprise information system. In this paper, we describe advanced data service architecture for modern enterprise information system. This architecture solves two main issues: semantic integration of data and adaptability of data server...
To allow the distribution of control and visibility of cross-organizational process models and to increase availability and performance of the processes, a process model can be fragmented into logically different parts and distributed in the enterprise architecture. Fragmentation algorithms and execution environments that connect the fragmented process model parts together, recreating the original...
In this paper we present a new architecture for the Cloud Integrator platform that extends it in two directions. The first one aimed at improving the way of an application can be defined by a developer. Instead of dealing with the burden of defining applications only by specifying semantic workflows in terms of activities expressed as a tuple <task, object>, a developer can rely on the definition...
The Model Driven Engineering (MDE) has been proposed to support the development, maintenance and evolution of software systems. In this context several approaches for transformation models have been proposed in the literature. They suffer from two major limitations: i) they have been tested on homogeneous metamodels (e.g., Ecore, UML, Minjava, Kermeta …), and ii) they use common notions and concepts,...
Heath information exchange (HIE) is the next step of health informatics development in China. Conformed to the administration feature, the design of HIE platform adopts a centralized architecture, which has to accommodate large amount of health information and support various types of query and data retrieval. Cloud computing is a suitable for the technology requirements of centralized design. In...
The constantly increasing dynamics of the world economy and the shift of business values in accordance with the new values of the current society has lead to the development of new Internet oriented Enterprise Systems. This paper is concerned with the transformation of such systems in regard to the new paradigms of Future Internet and Cyber -- Physical Systems. A Distributed Semantic Middleware is...
Formal verification of business models has become recently an intensively researched area. Application of formal methods in this field necessities in overcoming several problems. Firstly, business analyst and designers rarely have enough skills and motivation to manually build abstract and formal specifications, hence, it arises the need to provide tools for an automated translation of business models...
This paper presents a methodology for transforming business rules (BR) written in natural language (NL) such as English into a set of executable models as Unified Modeling Language (UML), Structured Query language (SQL), etc. As the direct automatic transformation of NL specifications to executable models is very difficult due to the inherent ambiguities of NL, this methodology aims at using the Semantics...
Policy-based management is a flexible approach for the management of networks as policies make context-sensitive and automated decisions. For their effective development it is desired to specify policies at a high level of abstraction initially and to refine them until they are represented in a machine-executable way. We present an approach that uses models to specify event-condition-action (ECA)...
