Just Another Perl Hack Neil Bowers1 Canon Research Centre Europe
Weblint: Just Another Perl Hack Neil Bowers1 Canon Research Centre Europe Abstract Weblint is a utility for checking the syntax and style of HTML pages. It was inspired by lint [15], which performs a similar function for C and C++ programmers. Weblint does not aspire to be a strict SGML validator, but to provide helpful comments for humans. The importance of quality assurance for web sites is introduced, and one particular area, validation of HTML, is described in more detail. The bulk of the paper is devoted to weblint: what it is, how it is used, and the design and implementation of the current development version. 1. Introduction The conclusion opens with a summary of the information and opinions given in this paper. A Web sites are becoming an increasingly critical part of selection of the lessons learned over the last four years how many companies do business. For many companies is given, followed by plans for the future, and related web sites are their business. It is therefore critical that ideas. owners of web sites perform regular testing and analysis, to ensure quality of service. 2. Web Site Quality Assurance There are many different checks and analyses which The following are some of the questions you should be you can run on a site. For example, how usable is your asking yourself if you have a web presence. I have site when accessed via a modem? An incomplete list of limited the list to those points which are relevant to similar analyses are given at the start of Section 2. -

HTML - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/HTML HTML From Wikipedia, the free encyclopedia HyperText Markup Language ( HTML ) is the main HTML markup language for displaying web pages and other (HyperText Markup Language) information that can be displayed in a web browser. Filename .html, .htm HTML is written in the form of HTML elements extension consisting of tags enclosed in angle brackets (like <html> ), within the web page content. HTML tags most Internet text/html commonly come in pairs like <h1> and </h1> , although media type some tags, known as empty elements , are unpaired, for Type code TEXT example <img> . The first tag in a pair is the start tag , the second tag is the end tag (they are also called opening Uniform Type public.html tags and closing tags ). In between these tags web Identifier designers can add text, tags, comments and other types of Developed by World Wide Web Consortium & text-based content. WHATWG The purpose of a web browser is to read HTML Type of Markup language documents and compose them into visible or audible web format pages. The browser does not display the HTML tags, but Extended SGML uses the tags to interpret the content of the page. from HTML elements form the building blocks of all websites.

Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC
Implementing OGC Web Map Service Client Applications Using JSP, JSTL and XMLC Hao Ding , Richard Pascoe & Neville Churcher Department of Computer Science University of Canterbury. Christchurch, New Zealand Phone: +64 3 364-2362 Fax: +64 3 364-2569 Email: [email protected] , {richard, neville}@cosc.canterbury.ac.nz Presented at SIRC 2002 – The 14th Annual Colloquium of the Spatial Information Research Centre University of Otago, Dunedin, New Zealand th December 3-5 2002 ABSTRACT Java technologies are widely used in web application development. In this paper are described three approaches to developing Java-based web applications and our experiences with applying each to the development of client that interact with servers implementing the OGC (Open GIS Consortium) Web Map Service (WMS) specification. Also described is the installation and configuration of open source software that implements the WMS specification. The paper is concluded with some preliminary insights into when one of the three approaches to WMS client implementation is more suited to another. Keywords and phrases: WMS, JSP, JSTL, XMLC, map layer, web map server 1.0 INTRODUCTION Of the many technologies, such as Common Gateway Interface (CGI), Active Server Pages (ASP), JavaServer Pages (JSP), that are used to develop web applications, three are of particular interest to the research presented here. These three technologies or approaches to developing clients that utilise web services are JavaServer Pages (JSP), JSP with the use of tags from the JSP Standard Tag Library (JSTL), and the eXtensible Markup Language Compiler (XMLC). JSP is a more convenient way to write Java servlets, and allows the insertion of Java code directly into static HTML (Hypertext Markup Language) pages. -

Klaus-Peter Fähnrich Dr. Axel-Cyrille Ngonga Ngomo institution: Leipzig University, Faculty for Mathematics and Computer Science time frame: January 2013 - March 2016 ABSTRACT Over the last decades, several billion Web pages have been made available on the Web. The growing amount of Web data provides the world’s largest collection of knowledge.1 Most of this full-text data like blogs, news or encyclopaedic informa- tion is textual in nature. However, the increasing amount of structured respectively semantic data2 available on the Web fosters new search paradigms. These novel paradigms ease the development of natural language interfaces which enable end- users to easily access and benefit from large amounts of data without the need to understand the underlying structures or algorithms. Building a natural language Question Answering (QA) system over heteroge- neous, Web-based knowledge sources requires various building blocks. -
Tool Support for Computer Role-Playing Game Programming: Foundations, Guidelines and Applications
Tampereen teknillinen yliopisto. Julkaisu 1237 Tampere University of Technology. Publication 1237 Juha-Matti Vanhatupa Tool Support for Computer Role-Playing Game Programming: Foundations, Guidelines and Applications Thesis for the degree of Doctor of Science in Technology to be presented with due permission for public examination and criticism in Tietotalo Building, Auditorium TB222, at Tampere University of Technology, on the 17th of October 2014, at 12 noon. Tampereen teknillinen yliopisto - Tampere University of Technology Tampere 2014 ISBN 978-952-15-3341-9 (printed) ISBN 978-952-15-3393-8 (PDF) ISSN 1459-2045 Abstract Computer role-playing games (CRPGs) are a genre of computer games, which aim at providing similar player experience than their ancestors, paper-and- pen role-playing games. For a type of digital games, their evolution is already rather long, as the first ones were created in 1980s. Typically CRPGs em- phasize character development and to support this huge fantasy worlds and sophisticated storylines are also present. CRPG development has unique challenges, which derive from these typical features. Content creation is a continuous issue, since huge virtual worlds and long storylines must be filled with content. Personalization is also an important issue, because all fun of creating personalized character is lost if it has no effect into the game. Low starting threshold is important for successful game. It is becoming essential that the player can start playing quickly and she is not required to spent time waiting the installation to be completed. This can be achieved by web-based approach, since web-based games do not require installations.
