The last few years have seen two parallel trends emerge. The first of such trends is set by technologies such as Near Field Communication, 2D Bar codes, RFID and others that support the association of digital information with virtually every object. Using these technologies ordinary objects such as coffee mugs or advertisement posters can provide information that is easily processed. The second trend is set by (semantic) Web services that provide a way to automatically invoke functionalities across the Internet lowering interoperability barriers. The PERCI system, discussed in the chapter, provides a way to bridge between these two technologies allowing the invocation of Web services using the information gathered from the tags effectively transforming every object in a service proxy.

With growing interest in Semantic Web services and emerging standards, such as OWL, WSMO, and SWSL in particular, the importance of applying logic-based models to develop core elements of the intelligent Semantic Web has been more closely examined. However, little research has been conducted in Semantic Web services on issues of non-mono-tonicity and uncertainty of Web services retrieval and selection. In this paper, the authors propose a non-monotonic modeling and uncertainty reasoning framework to address problems related to adaptive and personalized services retrieval and selection in the context of micro-payment processing of electronic commerce. As intelligent payment service agents are faced with uncertain and incomplete service information available on the Internet, non-monotonic modeling and reasoning provides a robust and powerful framework to enable agents to make service-related decisions quickly and effectively with reference to an electronic payment processing cycle.

Much of the early focus in the area of Semantic Web has been on the development of representation languages for static conceptual information; while there has been less emphasis on how to make Semantic Web applications practically useful in the context of knowledge work. To achieve this, a better coupling is needed between ontology, service descriptions, and workflow modeling, including both traditional production workflow and interactive workflow techniques. This chapter reviews the basic technologies involved in this area to provide system and business interoperability, and outlines what can be achieved by merging them in the context of real-world workflow descriptions.

NFC devices are used in contactless payment systems, similar to those used in credit cards electronic ticket smartcards and allow mobile payment to replace and supplement these systems. Specifically, combining NFC enabled devices or NFC mobile phones with RFID tags offers additional benefits when compared to traditional RFID solutions. When an application requires that a device have frequent interaction with tags at numerous process points, the high expense of using traditional handheld RFID readers is cost prohibitive. By replacing handheld readers with NFC-enabled phones at data collection points, the ROI for the application increases. HID Trusted Tag® Services is an example of an application that combines HID Global's patented Near Field Communication (NFC) trusted tag technology and cloud-based authentication platform to add unique and trusted identities to everyday objects that can be read by NFC-enabled mobile devices. This is ideal for establishing proof of presence, digital out of home (DOOH) and electronic visitor verification (EVV) and also serves as a real-world application of the Internet of Things (IoT) that has been discussed in Chapter 1. Some of the examples of NFC based mobile devices is discussed in the chapter.

Model Driven Approach

The benefits of incorporating Semantic Web Services in web applications are well documented. However, both the real-world implementation and adoption of these services are still rather limited in practice. This is despite the promises that extend syntactic Web services with capabilities such as automatic service discovery, composition, and execution. Some of the barriers to the real-world implementation are the complexities and tool support related to the development of Semantic Web Services. In this article, the main challenge that is addressed is the tight coupling of existing Semantic Web Services (SWS) development platforms to specific semantic description languages and service description languages, which unintentionally lead to unbending service development environments. The main contribution in this article is therefore a model-driven approach called iSemServ that exploits mature technologies, such as UML, and model-transformation techniques for simplifying and semi-automating the development of SWS using description languages of choice, such as Web Ontology Language for Services (OWL-S) and Web Application Description Language (WADL). A design science research methodology was employed in conducting the study. The suggested approach was practically implemented as an Eclipse plug-in and evaluated based on a real-world use case scenario and comparative analysis of related solutions. The evaluation results show that our proposed solution is relevant and appropriate in aiding the semi-automatic development of SWS, albeit with a number of limitations that could be addressed by extending the proposed practical solution.

Node Location

In this paper we deal with discovering a geographic location of a node in the Internet. Knowledge of location is a fundamental element for many location based applications and web services. We focus on location finding without any assistance of the node being located - client-independent estimation. We estimate a location using  communication latency measurements between nodes in the Internet. The latency measured is converted into a geographic distance which is used to derive a location by the multilateration (triangulation) principle. We analyse the latency-to-distance conversion with a consideration of location underestimation which is a product of multilateration failure. We demonstrate that location underestimations do not appear in experimental conditions. However with a real-world scenario, a number of devices cannot be located due to underestimations. Finally, we propose a modification to reduce the number of underestimations in real-world scenarios.DOI: http://dx.doi.org/10.5755/j01.itc.44.3.8353

The high use of the internet makes the availability of hotspots a demand for all groups of Indonesian people. The use of computer networks using wifi is widely available in various places, for example in offices, schools, cafes, etc. A person must first login to the wifi network in order to access the internet, the login process is carried out by inputting a username and password, in this process the accuracy of user reading is very necessary, it is not uncommon for users to enter the username and password incorrectly which consists of a fairly long row of numbers and must re-enter it username and password. Therefore, it is necessary to build a support system, namely a wifi subscription payment system using NFC technology on an Android-based smartphone. This NFC technology can help during the login process to a wifi network. Wifi users no longer need to enter a long user name and password to log in, besides that NFC technology is a subscription identity card that can be used anywhere and easy to carry anywhere. This system also makes it easier for wifi corner business owners, because this system performs AAA (Authentication, Authorization, and Accounting) functions for users who want to access an internet network. After making the application, testing is carried out by measuring the reading distance of the NFC reader on the smartphone to the NFC tag.
