A User-Centric Knowledge Creation Model in a Web of Object-Enabled Internet of Things Environment

User-centric service features in a Web of Object-enabled Internet of Things environment can be provided by using a semantic ontology that classifies and integrates objects on the World Wide Web as well as shares and merges context-aware information and accumulated knowledge. The semantic ontology is applied on a Web of Object platform to virtualize the real world physical devices and information to form virtual objects that represent the features and capabilities of devices in the virtual world. Detailed information and functionalities of multiple virtual objects are combined with service rules to form composite virtual objects that offer context-aware knowledge-based services, where context awareness plays an important role in enabling automatic modification of the system to reconfigure the services based on the context. Converting the raw data into meaningful information and connecting the information to form the knowledge and storing and reusing the objects in the knowledge base can both be expressed by semantic ontology. In this paper, a knowledge creation model that synchronizes a service logistic model and a virtual world knowledge model on a Web of Object platform has been proposed. To realize the context-aware knowledge-based service creation and execution, a conceptual semantic ontology model has been developed and a prototype has been implemented for a use case scenario of emergency service.

Knowledge-based open Internet of Things service provisioning architecture on beacon-enabled Web of Objects

Web of Objects uses a semantic ontology to create and provide knowledge-based Internet of Things services in terms of virtual objects and composite virtual objects. The objects are created through virtualization with the use of semantic ontology to form the virtual objects, where multiple virtual objects are combined to form the composite virtual objects to offer the services. Beacon-enabled Web of Objects is the extension of the existing web that allows the beacon to broadcast the uniform resource identifier of the real-world object to the nearer mobile devices. Based on the user selection and request, the service is handled and offered by the Web of Objects platform; thus, an architecture on the beacon-enabled Web of Objects has been proposed in this article. To offer the knowledge-based services, a knowledge creation model has been presented. To realize the knowledge-based service features on the proposed architecture, a use case scenario has been presented and a conceptual semantic ontology model has been designed. Finally, to assess the features, a prototype has been implemented and demonstrated on the use case scenario.

Modules to optimize the performance of an ERP based integrated information system

To meet the challenges in the modern business world, every organization must have a complete structure to maintain its management and system. Nowadays organizational structure totally depends on an automated system. Enterprise Resource Planning (ERP) integrates internal and external information across the entire organization embraces finance/accounts, manufactures, sales and service; and automates these activities with an integrated computer-based application. ERP is a complex software system used to manage information required to run large organization. The main goal of an ERP is data flow among the departments of an organization. Two modules named, Schedule Manager and Notice Manager have been integrated with ERP. Throughout the experiment on ERP based software named - Software Application Production (SAP), some key ways have been explored through which the software performs better with more user friendly.

Knowledge based open IoT service provisioning through cooperation between physical web and WoO

Semantic ontology in Web of Object (WoO) creates and provides services in terms of Virtual Objects (VO) and Composite Virtual Object (CVO). Virtualizing the physical devices and resources as well as conceptual entities would form VOs, where CVOs are formed with the interrelated VOs to provide detailed information and services. Interaction between the physical devices and the smartphone on the physical web standard extends IoT services on WoO platform. Procedural approach for the interaction among the physical device, smartphone and WoO application server has been presented. A conceptual semantic ontology model for information reusability and interoperability among the VOs, the functional model of WoO platform and an implementation architecture have been presented.

WoO enabled IoT service provisioning based on learning user preferences and situation

One of the reasons behind failure or not being successful of an IoT service is due to the fact that, such a service do not cater to the end user needs precisely. An important ingredient in successful IoT service provisioning is to intelligently select service using the preferences and situation of requesting users. This not only provides effective service delivery but also reduces the time of service processing. Preferences of service user can be modeled by detecting regularities in their behavior and produce a hypothesis about their preferences. To enable service provisioning real world objects are virtualized using semantic ontology in Web of Objects (WoO) platform, to be interoperable and interconnected with each other. This paper proposes an approach to dynamic service provisioning based on user preferences and situation in a WoO enabled IoT system. It also contributes Real World Knowledge (RWK) model incorporating user preferences and situational information.

Knowledge creation model in WoO enabled smart ageing IoT service platform

Intelligent service provisioning for smart ageing requires not only the current status of smart objects, but also the knowledge of the service and its surrounding environment. Hence, context information is detected by processing the stream of data and the situation is recognized by reasoning them to project the prediction of the service environment as well as to update the knowledge. Knowledge based IoT service provisioning can be achieved in terms of virtual objects and composite virtual objects in the Web-of-Objects platform. Web-of-Objects allows the semantic ontology to virtualize the objects, which can express the knowledge through the interrelation of the virtual objects. This paper proposes a knowledge creation model in Web-of-Objects platform that helps in learning the status of the objects to update the knowledge through machine learning technique, which has been considered in service request analysis for user-centric service provisioning. To realize the intelligent service features, a use case scenario has been studied and a prototype has been implemented.

IoT learning model based on virtual object cognition

Intelligent service provisioning in the Internet of Things infrastructure can be achieved by discovering and composing most relevant virtual objects and autonomic modification of context information that require learning the system behavior through steady association between the virtual object and the real world object. To meet these challenges, Web-of-Objects enables the objects to be deployed, maintained and operated in the Internet of Things through virtualizing the real world objects with the use of semantic ontology. Learning model can be represented in terms of composite virtual object that is formed by combining multiple functionalities of virtual objects. Different functionalities at the virtual object level and their iteration enable the cognition in virtual object. The creation and functional architecture of virtual object in Web-of-Objects have been discussed. For the efficient discovery and composition of virtual object, a Web-of-Objects based learning model has been proposed in this paper. Finally, to realize the service composition, a use-case scenario has been studied.

Logistic Model to Support Service Modularity for the Promotion of Reusability in a Web Objects-Enabled IoT Environment

Due to a very large number of connected virtual objects in the surrounding environment, intelligent service features in the Internet of Things requires the reuse of existing virtual objects and composite virtual objects. If a new virtual object is created for each new service request, then the number of virtual object would increase exponentially. The Web of Objects applies the principle of service modularity in terms of virtual objects and composite virtual objects. Service modularity is a key concept in the Web Objects-Enabled Internet of Things (IoT) environment which allows for the reuse of existing virtual objects and composite virtual objects in heterogeneous ontologies. In the case of similar service requests occurring at the same, or different locations, the already-instantiated virtual objects and their composites that exist in the same, or different ontologies can be reused. In this case, similar types of virtual objects and composite virtual objects are searched and matched. Their reuse avoids duplication under similar circumstances, and reduces the time it takes to search and instantiate them from their repositories, where similar functionalities are provided by similar types of virtual objects and their composites. Controlling and maintaining a virtual object means controlling and maintaining a real-world object in the real world. Even though the functional costs of virtual objects are just a fraction of those for deploying and maintaining real-world objects, this article focuses on reusing virtual objects and composite virtual objects, as well as discusses similarity matching of virtual objects and composite virtual objects. This article proposes a logistic model that supports service modularity for the promotion of reusability in the Web Objects-enabled IoT environment. Necessary functional components and a flowchart of an algorithm for reusing composite virtual objects are discussed. Also, to realize the service modularity, a use case scenario is studied and implemented.

Microservices in Web Objects Enabled IoT Environment for Enhancing Reusability

In the ubiquitous Internet of Things (IoT) environment, reusing objects instead of creating new one has become important in academics and industries. The situation becomes complex due to the availability of a huge number of connected IoT objects, and each individual service creates a new object instead of reusing the existing one to fulfill a requirement. A well-standard mechanism not only improves the reusability of objects but also improves service modularity and extensibility, and reduces cost. Web Objects enabled IoT environment applies the principle of reusability of objects in multiple IoT application domains through central objects repository and microservices. To reuse objects with microservices and to maintain a relationship with them, this study presents an architecture of Web of Objects platform. In the case of a similar request for an object, the already instantiated object that exists in the same or from other domain can be reused. Reuse of objects through microservices avoids duplications, and reduces time to search and instantiate them from their registries. Further, this article presents an algorithm for microservices and related objects discovery that considers the reusability of objects through the central objects repository. To support the reusability of objects, the necessary algorithm for objects matching is also presented. To realize the reusability of objects in Web Objects enabled IoT environment, a prototype has been designed and implemented based on a use case scenario. Finally, the results of the prototype have been analyzed and discussed to validate the proposed approach.

Exploiting interoperable microservices in web objects enabled Internet of Things

The vision of internet of things is to connect every object beyond the boundaries of anywhere and whenever for the provision of services from the smart home user to fourth industrial revolution. The objects in the internet of things will be more heterogeneous because of their specialty and accuracy in their domain. Now a days in the Internet of things the data and its machine understanding gets more importance and remain the focal point rather than the objects that generate that data changes frequently due to innovations and their wears and tears. To make the machine understanding, exchanging and sharing information and knowledge; these objects needs a light weight and novel platform for the provision of IoT services in the future. The Web of Objects is a platform for IoT services because of its service modularity with the support of interoperable microservices and virtualization and granularity of heterogeneous objects through composite virtual objects and virtual objects. To realize the cross domain IoT applications we proposed WoO enabled interoperable microservices architecture and present a reference use case for the implementation.
