An XML/RST-based approach to multilingual document generation for the web

This paper shows how the framework of Rhetorical Structure Theory (RST) for discourse modelling can be expressed through XML annotations and then used to implement a natural language generation (NLG) system for the web. The system applies simplified RST schemes to the elaboration of a master document in XML from which content segments are chosen to suit the user's needs. The personalisation of the document is achieved through the application of a sequence of filtering levels of content selection based on the user aspects given as input.This research was partly supported by the Basque Government (XML-Bi, PI1999-72 project)

XML Integrated Environment for Service-Oriented Data Management

The proliferation of XML as a family of related standards including a markup language (XML), formatting semantics (XSL style sheets), a linking syntax (XLINK), and appropriate data schema standards have emerged as a de facto standard for encoding and sharing data between various applications. XML is designed to be simple, easily parsed and self-describing. XML is based on and support the idea of separation of concerns: information content is separated from information rendering, and relationships between data elements are provided via simple nesting and references. As the XML content grows, the ability to handle schemaless XML documents becomes more critical as most XML documents do not have schema or Document Type Definitions (DTDs). In addition, XML content and XML tools are often required to be combined in effective ways for better performance and higher flexibility. In this research, we proposed XML Integrated Environment (XIE) which is a general-purpose service-oriented architecture for processing XML documents in a scalable and efficient fashion. The XIE supports a new software service model that provides a proper abstraction to describe a service and divide it into four components: structure, connection, interface and logic. We also proposed and implemented XIE Service Language (XIESL) that can capture the creation and maintenance of the XML processes and the data flow specified by the user and then orchestrates the interactions between different XIE services. Moreover, XIESL manages the complexity of XML processing by implementing an XML processing pipeline that enables better management, control, interpretation and presentation of the XML data even for non-professional users. The XML Integrated Environment is envisioned to revolutionize the way non-professional programmers see, work and manage their XML assets. It offers them powerful tools and constructs to fully utilize the XML processing power embedded in its unified framework and service-oriented architecture

DSpace Manual: Software version 1.5

DSpace is an open source software platform that enables organizations to: - Capture and describe digital material using a submission workflow module, or a variety of programmatic ingest options - Distribute an organization's digital assets over the web through a search and retrieval system - Preserve digital assets over the long term This system documentation includes a functional overview of the system, which is a good introduction to the capabilities of the system, and should be readable by nontechnical personnel. Everyone should read this section first because it introduces some terminology used throughout the rest of the documentation. For people actually running a DSpace service, there is an installation guide, and sections on configuration and the directory structure. Note that as of DSpace 1.2, the administration user interface guide is now on-line help available from within the DSpace system. Finally, for those interested in the details of how DSpace works, and those potentially interested in modifying the code for their own purposes, there is a detailed architecture and design section

Interactive Digital Terrestrial Television: The Interoperability Challenge in Brazil

This paper introduces different standards implemented in existing Digital Terrestrial Television Broadcasting systems to allow the fruition of interactive services and applications through digital Set Top Boxes. It focuses on the interoperability issue between the Brazilian and the European architectures. In fact, despite in Brazil the GEM specification has been designed to foster wide content compatibility across a range of interactive platforms, it has never come to a final implementation and deployment. As a result the interoperability issue has been deeply explored in the BEACON project and an innovative system architecture has been developed to deploy t-learning services across Europe and Brazil, providing integration of those systems that were not able to interoperate until nowadays. This work is an important step in the direction of standards' interoperability. As a result, MHP and Ginga NCL-Lua implementation appeared to be the very best choice to deliver interactive services in an interoperable mode between European and Brazilian digital television

Adaptive Layout for Interactive Documents

This thesis presents a novel approach to create automated layouts for rich illustrative material that could adapt according to the screen size and contextual requirements. The adaption not only considers global layout but also deals with the content and layout adaptation of individual illustrations in the layout. An unique solution has been developed that integrates constraint-based and force-directed techniques to create adaptive grid-based and non-grid layouts. A set of annotation layouts are developed which adapt the annotated illustrations to match the contextual requirements over time

Implementation architectures for natural language generation

Generic software architectures aim to support re-use of components, focusing of research and development effort, and evaluation and comparison of approaches. In the field of natural language processing, generic frameworks for understanding have been successfully deployed to meet all of these aims, but nothing comparable yet exists for generation. The nature of the task itself, and the current methodologies available to research it, seem to make it more difficult to reach the necessary level of consensus to support generic proposals. Recent work has made progress towards establishing a generic framework for generation at the functional level, but left open the issue of actual implementation. In this paper, we discuss the requirements for such an implementation layer for generation systems, drawing on two initial attempts to implement it. We argue that it is possible and useful to distinguish “functional architecture ” from “implementation architecture” for generation systems. 1 The Case for a Generic Software Architecture for NLG Most natural language generation (NLG) systems have some kind of modular structure

Framework for ubiquitous and voice enabled web applicattions development.

RESUMEN La cantidad de dispositivos con capacidad de conexión a Internet crece rápidamente. En la actualidad se dispone de teléfonos móviles basados en tecnología WAP (Wireless Application Protocol) o I-Mode, Agendas Digitales Personales, Kioskos Internet, teléfonos convencionales basados en acceso a la Web por medio de la voz, dispositivos basados en televisión interactiva, electrodomésticos, entre otros. Desarrollar una versión de una aplicación web para cada uno de los dispositivos con conectividad a la Web resulta inviable. Por otra parte, desarrollar aplicaciones web que puedan ser visualizados en forma apropiada y aprovechando al máximo las capacidades del dispositivo se constituye en una tarea compleja. En esta tesis se propone un framework, entendido como un marco de trabajo genérico, que sirva como guía para el desarrollo de portales web pervasivos que puedan ser accedidos desde múltiples dispositivos, evitando el desarrollo de un portal por cada uno y teniendo en cuenta las grandes variaciones pueden existir en sus capacidades. Adicionalmente se ha planteado un modelo de agrupamiento de dispositivos, que permita definir una serie de grupos, así como las características asociadas a los mismos, en forma tal que puedan generarse posteriormente los formatos asociados a estos grupos de dispositivos y no a elementos individuales y se ha propuesto y validado una arquitectura de referencia para el desarrollo de aplicaciones pervasivas, que no genere dependencia de tecnologías de servidor, y que permita incorporar la solución de agrupamiento planteada previamente. ____________________________________________________________________________________________________The purpose of the Ubiquitous or Pervasive Computing - an emergent paradigm of personalized computation- is to obtain device interoperability under different conditions. The devices were designed for different purposes by different companies or from different technological generations. The ever increasing market of web enabled devices has brought up diverse challenges related to the difficulty of visualizing content in a unified form to diverse clients, while at the same time taking into account the great differences in the capacities of these devices. It is not feasible to develop a separate application for each of these devices, simply because the number of different devices is too high and still growing. In the analysis of existing proposals dealing with the modelling of ubiquitous web applications, the link that exists between the logical and conceptual modelling and the physical modelling of the applications is not clear enough, and the way in which the context aspects related to web access from these devices cannot be specified. On the other hand, the available commercial products are supplier-specific. Every future platform change would a costly and painstaking process In this thesis we present a proposal of a framework for the development of web applications that can be accessed from different types of devices, such as PCs, PDAs, mobile phones based on diverse technologies (like WAP and I-Mode) and conventional telephones that access the web through voice gateways and voice portals. The proposed framework serves as a guide for the development of this type of applications and it can be deployed to different server configurations and software development technologies. In order to obtain this objective, a description of diverse theoretical elements related to dynamic generation of information that can be acceded by devices has been made, as well as a description of involved technologies whose hardware, software and connectivity characteristics vary remarkably. The theoretical study was carried out in parallel with tests based on the different technologies used. A multilingual-ubiquitous traffic information portal was used to test the theory in an operational environment
