A path-based RDF query language for CC/PP and UAProf

By introducing a new method to apply a path expression to RDF queries, we present a new path-based RDF query language, RPath, for CC/PP and UAProf. CC/PP and UAProf, two of the applications of RDF, are standards that describe the context of both users and devices. To achieve high service levels, content adaptation systems must address user and device information effectively. RPath is designed to intemperate seamlessly with CC/PP and UAProf. RPath is also capable of processing features of CC/PP and UAProf. Example RPath queries and comparisons of RPath relative to other RDF query languages are also provided.

XML Document Adaptation Queries (XDAQ): An Approach to Adaptation Reasoning Using Web Query Languages

Adaptive web applications combine data retrieval on the web with reasoning so as to generate context dependent contents. The data is retrieved either as content or as context specifications. Content data is, for example, fragments of a textbook or e-commerce catalogue, whereas context data is, for example, a user model or a device profile. Current adaptive web applications are often implemented using ad hoc and heterogeneous techniques. This paper describes a novel approach called ”XML Document Adaptation Queries (XDAQ)” requiring less heterogeneous software components. The approach is based on using a web query language for data retrieval (content as well as context) and on a novel generic formalism to express adaptation. The approach is generic in the sense that it is applicable with all web query and transformation languages, for example with XQuery and XSLT.

Design and Implementation of Printing Protocol for Mobile Phones

This paper describes the design and implementation of an imaging protocol for mobile phones. This protocol enables a user to transfer content from a mobile phone to various display devices (e.g. projector) and control content presentation (e.g. display, forward, backward, etc.) by the same mobile phone, via various network interfaces (e.g. WLAN, Bluetooth, USB and IrDA). Using the proposed protocol, a mobile phone user can realize a content presentation equivalent to that possible with a PC. To ensure interoperability with existing display devices, we set a gateway between the mobile phone and the display devices. The gateway outputs the commands accepted by the device selected to allow the mobile phone user to control the device transparently.

Recent Activities in PUCC and Its Application to Integrated Home Network Control and Management

We have been developing and standardizing middleware technologies for home network control from a mobile phone in Peer-to-peer Universal Computing Consortium (PUCC), which is a consortium towards de facto standardization. We discussed issues for unified home network control from a mobile phone. We describe the peer-to-peer/overlay networking technologies developed by PUCC, to resolve those issues. We describe recent PUCC activities, which include the development of PUCC specifications Release 1, development of prototypes implementing PUCC protocols, demonstrations of such prototypes at international leading tradeshows such as CES and CeBIT, and activities towards international standardization. PUCC started a new project for integrated home network control and management in 2009, based on those activities.

Overview of Peer-to-Peer Universal Computing Consortium (PUCC): Background, Current Status and Future Plan

P2P technology is very important to construct low cost efficient network, and it is used to realize better home network to connect various kinds of digital equipments and devices for daily use. The authors introduced the standard development organization called PUCC to support such better P2P networks and its services, and give brief description about its current activities as well as the future activity plans..

A Framework for Descriptions and Reasoning for Adaptive Composite Service Structure and Behavior

In this paper, we present a framework developed for characterizing the whole spectrum of synthesized complex service by interacting with devices in peer-to-peer networking environments. Recently, a number of techniques have been proposed to support complex adaptive and dynamic service composition in p2p. However, these techniques have captured only a subset of service composition over p2p networks and represented some points within the spectrum of complex service, such as service discovery and service descriptions. We have explored a new model to determine how to manage complex services in terms of notions of comprehensive services, adaptive service commitment, modification and recovery, service atomicity and service descriptions in competitive and cooperative ad-hoc p2p networking environment.

Empirical study on location-based Web service based on CC/PP and RDF

In this paper, we present empirical study on new framework of location information service on the Web with CC/PP and RDF. We have implemented a prototype system and explored a new technique to exchange the location of a mobile device on the Web with CC/PP and its exchange protocol to localize a Web service. We have used CC/PP to describe users context in the form of CC/PP and RDF, and exchange them via HTPP Extension framework to localize Web contents based on the terminal location. In addition, we have harmonized CC/PP with P3P to protect users privacy and specify the information to achieve the services on a server side. We have investigated a new way for describing such kind of information with CC/PP and its protection mechanism by P3P. Finally, we have developed experimental systems to demonstrate effectiveness of our techniques. We believe CC/PP and RDF can be applied for describing users environment, and P3P can complement the security aspect of CC/PP.

An Object-Oriented Native-Language Support for the Andrew Toolkit

The development of a generic, highly flexible, and extensible native-language support facility has becomes necessary for computer users. We have designed and developed a native-language support interface for the Andrew Toolkit, incorporating an object-oriented programming approach, and developed applications to run on it. We have designed a uniform data model which can handle any native language. Using the object-oriented programming language’s code-sharing facility, we share the program code as much as possible based on its data model. We incorporate the MVC (Model View Controller) model of Smalltalk to support native-language processing. Each native language has its own data model and view. This mechanism provides advantages when extending an existing program. Incorporating this design, a program which supports the dynamic loading of objects on the Andrew Toolkit becomes able to support native-language processing without any modification.
