  • The Semantic
    The Fate of the Semantic Web Technology experts and stakeholders who participated in a recent survey believe online information will continue to be organized and made accessible in smarter and more useful ways in coming years, but there is stark dispute about whether the improvements will match the visionary ideals of those who are working to build the semantic web. Janna Quitney Anderson, Elon University Lee Rainie, Pew Research Center’s Internet & American Life Project May 4, 2010 Pew Research Center’s Internet & American Life Project An initiative of the Pew Research Center 1615 L St., NW – Suite 700 Washington, D.C. 20036 202‐419‐4500 | pewInternet.org This publication is part of a Pew Research Center series that captures people’s expectations for the future of the Internet, in the process presenting a snapshot of current attitudes. Find out more at: http://www.pewInternet.org/topics/Future‐of‐the‐Internet.aspx and http://www.imaginingtheinternet.org. 1 Overview Sir Tim Berners‐Lee, the inventor of the World Wide Web, has worked along with many others in the Internet community for more than a decade to achieve his next big dream: the semantic web. His vision is a web that allows software agents to carry out sophisticated tasks for users, making meaningful connections between bits of information so “computers can perform more of the tedious work involved in finding, combining, and acting upon information on the web.”1 The concept of the semantic web has been fluid and evolving and never quite found a concrete expression and easily‐understood application that could be grasped readily by ordinary Internet users.

  • Will Impact Higher Education WEB
    Foroughi Web 3.0: How “the Internet of Everything” will impact Higher Education WEB 3.0: HOW THE “INTERNET OF EVERYTHING” WILL IMPACT HIGHER EDUCATION Abbas Foroughi College of Business, University of Southern Indiana [email protected] 812-465-1667 ABSTRACT Universities are finding that adopting Web 2.0 is necessary to remain competitive, while, at the same time, the evolution to Web 3.0 is on the horizon. This paper discusses Web 3.0, how it builds on Web 2.0, examples of current applications of Web 3.0, the potential benefits for higher education and lifelong learning which experts predict from Web 3.0 and concerns that have also been voiced. INTRODUCTION Over the past two decades, many institutions of higher learning and their students have reaped benefits from using Web 2.0 tools such as Wikis, Facebook, blogs, tagging, LinkedIn, virtual reality, social bookmarking, mashing, rss, podcasts, folksonomies, ePortfolios, chatrooms, and similar technologies, which facilitate communication, give participants a feeling of group membership, and are user-friendly. Specific benefits include: learning-related benefits: (Anderson, 2007; Alexander, 2006; Wesch, 2009; Reuben, 2008; McDonald, 2009; Brainard, 2007; Thompson, 2008; Minocha, 2009), such as facilitation of collaborative learning, development of independent learning skills, problem solving, team work, reflective learning, quick/early feedback from instructors, overcoming isolation of geographical distances, peer-to- peer support/feedback, visibility of students’ work, integration of multimedia assets, and the creation of informal relations between educators and students. Universities are finding that adopting Web 2.0 is necessary to remain competitive, while, at the same time, the evolution to Web 3.0 is on the horizon.

  • Knowledge-Based General Game Playing
    Knowledge-Based General Game Playing Dissertation zur Erlangung des akademischen Grades Doktor rerum naturalium (Dr. rer. nat.) vorgelegt an der Technischen Universitat¨ Dresden Fakultat¨ Informatik eingereicht von Dipl.-Inf. Stephan Schiffel geboren am 15. 09. 1980 in Sebnitz Gutachter: Prof. Michael Thielscher, University of New South Wales Prof. Yngvi Bj¨ornsson, H´ask´olinn´ıReykjav´ık Datum der Verteidigung: 29.07.2011 Abstract General Game Playing (GGP) is concerned with the development of systems that can play well an arbitrary game solely by being given the rules of the game. This problem is considerably harder than traditional artificial intelligence (AI) game playing. Writing a player for a particular game allows to focus on the design of elaborate strategies and libraries that are specific to this game. Systems able to play arbitrary, previously unknown games cannot be given game-specific knowledge. They rather need to be endowed with high-level cognitive abilities such as general strategic thinking and abstract reasoning. This makes General Game Playing a good example of a challenge problem, which encompasses a variety of AI research areas including knowledge representation and reasoning, heuristic search, planning, and learning. Two fundamentally different approaches to GGP exist today, we call them knowledge-free and knowledge-based approach. The knowledge-free approach considers the game rules as a black box used for generating legal moves and successor states of the game. Players using this approach run Monte-Carlo simulations of the game to estimate the value of states of the game. On the other hand, the knowledge-based approach considers the components of a state (e.

  • Ary, a General Game Playing Program
    Ary, a general game playing program Jean M´ehat,Tristan Cazenave Abstract We present our program Ary that won the 2009 and 2010 General Game Playing competition. In General Game Playing (GGP), players have to play games they never encountered before. The rules are trans- mitted as a description in a specific language and the player have to au- tomatically analyse the rules and select a method of playing. 1 Introduction The field of program playing games is an extensively explored field of computer science and more particularly of artificial intelligence as it is a domain where common methods of reasonning are to be applied, while offering a closed world, completely described by the game rules. Moreover the quality of the play is easy to evaluate quantitatively by observing the matches outcomes, and a human expertise has been developped. Great successes have been obtained: in many games, including chess, programs routinely outplay even the best human player. The program usually embed a important body of knowledge that is specific of the game they play. This knowledge is used by the designer beforehand and limit somewhat the generality of the program. While a program like Deep Blue is able to play well chess, it can not play a match of Checker, or even Tic Tac Toe: while an expert in its domain, the playing program is limited to one game in its abilities, and these are not easily extended to other domains or even to other games. The Logic Group at the university of Stanford addresses this limitation with GGP. In a GGP match, the players receive the rules of the game they have to play in a specific langage called Game Description Language from a Game Master.
