  • Toward the Discovery and Extraction of Money Laundering Evidence from Arbitrary Data Formats Using Combinatory Reductions
    Toward the Discovery and Extraction of Money Laundering Evidence from Arbitrary Data Formats using Combinatory Reductions Alonza Mumford, Duminda Wijesekera George Mason University [email protected], [email protected] Abstract—The evidence of money laundering schemes exist undetected in the electronic files of banks and insurance firms scattered around the world. Intelligence and law enforcement analysts, impelled by the duty to discover connections to drug cartels and other participants in these criminal activities, require the information to be searchable and extractable from all types of data formats. In this overview paper, we articulate an approach — a capability that uses a data description language called Data Format Description Language (DFDL) extended with higher- order functions as a host language to XML Linking (XLink) and XML Pointer (XPointer) languages in order to link, discover and extract financial data fragments from raw-data stores not co- located with each other —see figure 1. The strength of the ap- Fig. 1. An illustration of an anti-money laundering application that connects proach is grounded in the specification of a declarative compiler to multiple data storage sites. In this case, the native data format at each site for our concrete language using a higher-order rewriting system differs, and a data description language extended with higher-order functions with binders called Combinatory Reduction Systems Extended and linking/pointing abstractions are used to extract data fragments based on (CRSX). By leveraging CRSX, we anticipate formal operational their ontological meaning. semantics of our language and significant optimization of the compiler.

  • Annotea: an Open RDF Infrastructure for Shared Web Annotations
    Proceedings of the WWW 10th International Conference, Hong Kong, May 2001. Annotea: An Open RDF Infrastructure for Shared Web Annotations Jos´eKahan,1 Marja-Riitta Koivunen,2 Eric Prud’Hommeaux2 and Ralph R. Swick2 1 W3C INRIA Rhone-Alpes 2 W3C MIT Laboratory for Computer Science {kahan, marja, eric, swick}@w3.org Abstract. Annotea is a Web-based shared annotation system based on a general-purpose open RDF infrastructure, where annotations are modeled as a class of metadata.Annotations are viewed as statements made by an author about a Web doc- ument. Annotations are external to the documents and can be stored in one or more annotation servers.One of the goals of this project has been to re-use as much existing W3C technol- ogy as possible. We have reacheditmostlybycombining RDF with XPointer, XLink, and HTTP. We have also implemented an instance of our system using the Amaya editor/browser and ageneric RDF database, accessible through an Apache HTTP server. In this implementation, the merging of annotations with documents takes place within the client. The paper presents the overall design of Annotea and describes some of the issues we have faced and how we have solved them. 1Introduction One of the basic milestones in the road to a Semantic Web [22] is the as- sociation of metadata to content. Metadata allows the Web to describe properties about some given content, even if the medium of this content does not directly provide the necessary means to do so. For example, ametadata schema for digital photos [15] allows the Web to describe, among other properties, the camera model used to take a photo, shut- ter speed, date, and location.

  • Advanced XHTML Plug-In for Iserver
    Advanced XHTML Plug-in for iServer Semester work Stefan Malaer <[email protected]> Prof. Dr. Moira C. Norrie Dr. Beat Signer Global Information Systems Group Institute of Information Systems Department of Computer Science 12th October 2005 Copyright © 2005 Global Information Systems Group. Abstract The iServer architecture is an extensible cross-media information platform enabling links between arbitrary typed objects. It provides some fundamental link concepts and is based on a plug-in mechanism to support various media types. The goal of this semester work was to develop a XHTML plug-in for iServer which enables links from XHTML documents to other XHTML documents as well as parts of them. The resulting iServext is a Firefox extension for iServer which provides visualization and authoring functionality for XHTML links. Furthermore, we investigated research in the area of link augmentation and provide an overview of recent technologies. iii iv Contents 1 Introduction 1 2 Augmented Linking 3 2.1 Need for augmented linking ........................... 3 2.1.1 Current link model ............................ 3 2.1.2 Approaches for link augmentation ................... 5 2.2 Related work .................................... 6 2.2.1 Chimera .................................. 6 2.2.2 Hyper-G/Hyperwave ........................... 6 2.2.3 Distributed Link Service ......................... 6 2.2.4 DHM/WWW and Extend Work ..................... 6 2.2.5 HyperScout ................................. 7 2.2.6 Link Visualization with DHTML ..................... 7 2.2.7 Amaya project ............................... 8 2.3 Link integration and authoring ......................... 9 2.4 Link visualization .................................. 11 2.4.1 Today’s link visualization ......................... 11 2.4.2 Possible presentations of link information .............. 11 2.4.3 Examples of link visualization .....................

  • Dynamic and Interactive R Graphics for the Web: the Gridsvg Package
    JSS Journal of Statistical Software MMMMMM YYYY, Volume VV, Issue II. http://www.jstatsoft.org/ Dynamic and Interactive R Graphics for the Web: The gridSVG Package Paul Murrell Simon Potter The Unversity of Auckland The Unversity of Auckland Abstract This article describes the gridSVG package, which provides functions to convert grid- based R graphics to an SVG format. The package also provides a function to associate hyperlinks with components of a plot, a function to animate components of a plot, a function to associate any SVG attribute with a component of a plot, and a function to add JavaScript code to a plot. The last two of these provides a basis for adding interactivity to the SVG version of the plot. Together these tools provide a way to generate dynamic and interactive R graphics for use in web pages. Keywords: world-wide web, graphics, R, SVG. 1. Introduction Interactive and dynamic plots within web pages are becomingly increasingly popular, as part of a general trend towards making data sets more open and accessible on the web, for example, GapMinder (Rosling 2008) and ManyEyes (Viegas, Wattenberg, van Ham, Kriss, and McKeon 2007). The R language and environment for statistical computing and graphics (R Development Core Team 2011) has many facilities for producing plots, and it can produce graphics formats that are suitable for including in web pages, but the core graphics facilities in R are largely focused on static plots. This article describes an R extension package, gridSVG, that is designed to embellish and transform a standard, static R plot and turn it into a dynamic and interactive plot that can be embedded in a web page.

  • Extended Link Visualization with DHTML: the Web As an Open Hypermedia System
    Extended Link Visualization with DHTML: The Web as an Open Hypermedia System Glenn Oberholzer and Erik Wilde Computer Engineering and Networks Laboratory Swiss Federal Institute of Technology, Z¨urich TIK Report 125 January 2002 Abstract The World Wide Web is by far the most successful hypermedia system, its name often being used synonymously for the Internet. However, it is based on a rather restricted hy- permedia model with limited linking functionality. Even though underlying systems may provide a richer data model, there is still the question of how to present this informa- tion in a Web-based interface in an easily understandable way. Assuming an underlying system similar to Topic Maps, which allows storing, managing, and categorizing meta data and links, we propose a presentation of extended links. We try to provide a usable way for users to handle the additional functionality. The mechanism is based on already available technologies like DHTML. It is one facet of our approach to make the Web more interconnected and to work towards a more richly and openly linked Web. Keywords: Electronic publishing (020), Graphic design (029), Hypermedia (036), Internet (045), World Wide Web (084), XLink, Linkbases, DHTML 1 Introduction Compared to many other hypermedia systems [24,11,16], the linking capabilities of the World Wide Web are rather limited. It only makes use of a few concepts of hypermedia. In recent years, however, new recommendations issued by the W3C like XML [3], XLink [10], and XPointer [9], or ISO/IEC’s Topic Maps [19] have tried to overcome this shortcoming. Due to the popularity of the Web, efforts have to be made to integrate and improve the current system with more sophisticated hypermedia concepts.

  • XML Projects in Japan and Fujitsu's Approach to Xlink/Xpointer
    UDC 621.395.74:651.55:681.32 XML Projects in Japan and Fujitsu’s Approach to XLink/XPointer VToshimitsu Suzuki VMasatomo Goto (Manuscript received June 2, 2000) The Extensible Markup Language (XML)1) is a markup language developed in response to a recommendation by the World Wide Web Consortium (W3C).2) It is a meta lan- guage used to make an information structure. XML’s original specification is the Stan- dard Generalized Markup Language (SGML).3) Now, XML is used not only as a format language but also as a framework in various areas beyond the SGML field. This paper describes the XML technology trends, the current state of XML technology, and some case studies in Japan and at Fujitsu. This paper also describes HyBrick,4) which is an XML/SGML browser that was demonstrated at SGML’97, and the XLink5)/XPointer6) technology. 1. Introduction verified through these experiments.

  • What Are... Xlink and Xpointer?
    What Are... XLink and XPointer? Brian Kelly explains XLink and XPointer. This article appears in the Web, and not the print version of Ariadne. Background The What Is ...? article in the last edition of Ariadne gave an introduction to XML, the Extensible Markup Language [1]. XML has been developed to overcome HTML's lack of extensibility - with XML you will be able to define your own element tags. We have already seen a variety of communities defining element tags for use within their community, such as MathML [2] and MusicML [3]. Besides lacking extensibility, HTML is also limited in its hyperlinking functionality. XLink and XPointer are currently being developed in order to address these limitations. XLink In HTML hyperlinking is normally achieved using the <A> (anchor) element. This provides a simple uni- directional link: normally clicking on a hypertext link will cause the current document to be replaced by a new document. XLink [4] provides much richer hyperlinking functionality which the hypertext community have argued is needed in order to provide a richer web infrastructure. XLink enables multiple destinations to be provided. For example consider the XML portion illustrated below. <p>What is an <a xml:link="extended"> <locator href="glossary.xml" role="Glossary definition"> <locator href="http://www.w3.org/TR/" role="XML Link specification"> <locator href="tutorial.xml" role="Tutorial"> <locator href="quiz.xml" role="Quiz">XLink?</a></p> This could be rendered by a conforming XML browser as shown in Figure 1. XLink also enables a variety of link behaviours to be specified, including embedding the resource in the original document, replacing the original document and creating a new window.
