  • WYSIWYM – Integrated Visualization, Exploration and Authoring of Semantically Enriched Un-Structured Content
    Semantic Web 1 (2013) 1–14 1 IOS Press WYSIWYM – Integrated Visualization, Exploration and Authoring of Semantically Enriched Un-structured Content Ali Khalili a, Sören Auer b a AKSW, Universität Leipzig, Augustusplatz 10, 04109 Leipzig, Germany [email protected] b CS/EIS, Universität Bonn, Römerstraße 164, 53117 Bonn, Germany [email protected] Abstract. The Semantic Web and Linked Data gained traction in the last years. However, the majority of information still is contained in unstructured documents. This can also not be expected to change, since text, images and videos are the natural way how humans interact with information. Semantic structuring on the other hand enables the (semi-)automatic integration, repurposing, rearrangement of information. NLP technologies and formalisms for the integrated representation of unstructured and semantic content (such as RDFa and Microdata) aim at bridging this semantic gap. However, in order for humans to truly benefit from this integration, we need ways to author, visualize and explore unstructured and semantically enriched content in an integrated manner. In this paper, we present the WYSIWYM (What You See is What You Mean) concept, which addresses this issue and formalizes the binding between semantic representation models and UI elements for authoring, visualizing and exploration. With RDFaCE and Pharmer we present and evaluate two complementary showcases implementing the WYSIWYM concept for different application domains. Keywords: Visualization, Authoring, Exploration, Semantic Web, WYSIWYM, WYSIWYG, Visual Mapping 1.

  • Revisiting XSS Sanitization
    Revisiting XSS Sanitization Ashar Javed Chair for Network and Data Security Horst G¨ortzInstitute for IT-Security, Ruhr-University Bochum [email protected] Abstract. Cross-Site Scripting (XSS) | around fourteen years old vul- nerability is still on the rise and a continuous threat to the web applica- tions. Only last year, 150505 defacements (this is a least, an XSS can do) have been reported and archived in Zone-H (a cybercrime archive)1. The online WYSIWYG (What You See Is What You Get) or rich-text editors are now a days an essential component of the web applications. They allow users of web applications to edit and enter HTML rich text (i.e., formatted text, images, links and videos etc) inside the web browser window. The web applications use WYSIWYG editors as a part of comment functionality, private messaging among users of applications, blogs, notes, forums post, spellcheck as-you-type, ticketing feature, and other online services. The XSS in WYSIWYG editors is considered more dangerous and exploitable because the user-supplied rich-text con- tents (may be dangerous) are viewable by other users of web applications. In this paper, we present a security analysis of twenty five (25) pop- ular WYSIWYG editors powering thousands of web sites. The anal- ysis includes WYSIWYG editors like Enterprise TinyMCE, EditLive, Lithium, Jive, TinyMCE, PHP HTML Editor, markItUp! universal markup jQuery editor, FreeTextBox (popular ASP.NET editor), Froala Editor, elRTE, and CKEditor. At the same time, we also analyze rich-text ed- itors available on very popular sites like Twitter, Yahoo Mail, Amazon, GitHub and Magento and many more.

  • Workshop 1: Introduction to LATEX
    Workshop 1: Introduction to LATEX Dan Parker and David Schwein Sunday, September 21, 2014 Welcome to the first of the Science Center’s LATEX workshops! By the end of today’s workshop, you will be able to write a basic LATEX document containing mathematics. We assume that you have a working installation of LATEX and a LATEX editor. If you do not, please consult the installation guide. 1 Introduction 1.1 Questions and Answers What is LATEX? LATEX is a document preparation system, the de facto standard for mathematics, physics, and computer science. More technically, LATEX is a set of macros – extra commands – for the pro- gramming language TEX. Donald Knuth created TEX in the seventies because he was unhappy with the typography in one of his Art of Computer Program- ming books. He designed the program specifically for typesetting mathematics, and it was widely adopted in the years following its release. Later, in the eight- ies, Leslie Lamport wrote LATEX to extend TEX’s mostly low-level functionality. Today, LATEX has largely superseded TEX. Why should I use LATEX? 1.L ATEX documents are beautiful. Their typography is outstanding, espe- cially as compared to something like Microsoft Word. 2.L ATEX can make almost any document you can imagine and many others besides. 3.L ATEX is free, fast, and has virtually no bugs. LATEX is not for everyone, even among academics. While designing these workshops we found, for instance, that the chemistry department at Brown 1 does not care for LATEX. But mathematicians should certainly use LATEX, mainly because people will not take you seriously if you don’t.1 For the same reason, papers in other math-heavy scientific disciplines, such as physics and computer science, should also be prepared using LATEX.

  • Glossary of Terms
    Glossary of Terms Bandwidth: Bandwidth is the amount of information your connection to the Internet can carry, usually measured in bits per second. Banner: A banner is a graphic that is placed around a website for the use of advertising. Graphics can use static images and text, or even be animated. Banners are a great way to draw attention to special information or offers, whether it's on your site or an external site. Browser: A browser is the software you use to view web pages - in fact you're using one right now! Google Chrome, Mozilla Firefox, and Internet Explorer are some of the more common browsers, but there are others like Safari and Opera. Since each one is different, pages can vary in appearance depending on what browser is used. This has to be taken into account when designing and testing websites. CMS: Short for "Content Management System," a CMS allows a number of users to create and change website content through the use of WSYIWIG editors, without the need for HTML knowledge. Because the CMS is online, there is no need for external programs or uploading of separate page documents, and content can be published or unpublished with a single click. Compression: Compression makes files smaller for faster upload/download times, and less disk space usage. JPEGs use compression, making them ideal for web, but can lead to loss of image quality if re-saved multiple times. Cookie: A cookie is a message given to a web browser (the application you use to get online) by a web server.

  • Reproducible Research II: Sharing Files
    Reproducible Research II: sharing files LPO 9951 | Fall 2015 Contents The common thread . 1 Writing . 2 Equations . 5 References . 5 Graphics . 5 Attribution . 6 Ownership . 8 Final word . 8 PURPOSE In the last lecture on reproducible research, we discussed version control through git. Git works better with some types of file formats than others (e.g., plain text vs. MS Word). Today we will discuss a few of these not only in the service of using git, but with the purpose of improving how you can collaborate with others and share your work. We’ll also discuss attributions and ownership. The common thread Despite their seemingly different approaches to structuring text, the following syntaxes share two primary characteristics: 1. They are structured and saved using plain text files 2. They follow a WYSIWYM rather than WYSIWYG philosophy Plain text The simple MS Word .doc or .docx is a single file, right? Yes and no. The reason non-PC systems sometimes have trouble with MS Word documents is (1) they are saved in a proprietary format, and (2) those files are better thought of as file systems rather than as a single file. In other words, your MS Word document isn’t simply a record of the words on your screen, but also of a large number of format and system settings. This file structure is why, if you have tried, GitHub doesn’t display Windows documents that you may have pushed to it. Git works best with plain text (ASCII) files. There are a limited number of characters available, but for most of your scripting, you’ll be fine (do you really need that umlaut in your variable names?).
