Logic Programs, Iterated Function Systems, And Recurrent Radial Basis Function Networks, Sebastian Bader, Pascal Hitzler Sep 2004

Logic Programs, Iterated Function Systems, And Recurrent Radial Basis Function Networks, Sebastian Bader, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Graphs of the single-step operator for first-order logic programs—displayed in the real plane—exhibit self-similar structures known from topological dynamics, i.e., they appear to be fractals, or more precisely, attractors of iterated function systems. We show that this observation can be made mathematically precise. In particular, we give conditions which ensure that those graphs coincide with attractors of suitably chosen iterated function systems, and conditions which allow the approximation of such graphs by iterated function systems or by fractal interpolation. Since iterated function systems can easily be encoded using recurrent radial basis function networks, we eventually obtain connectionist systems which …


Connecting The Dots: Implicit Commonalities Among Cultural Morphogenesis, Structuration, And Market Economics, Stephen D. Cooper Sep 2004

Connecting The Dots: Implicit Commonalities Among Cultural Morphogenesis, Structuration, And Market Economics, Stephen D. Cooper

Communications Faculty Research

Perhaps the central foundational issue of our time is the relationship of human agency and social structure. If human actors are constrained by the rules and rhetoric of the social system, how is it that those actors can yet bring about radical change in that social system? A similar puzzle exists in economics: how is it that individual transactions both maintain and transform the marketplace? This paper begins to identify common ground implicit in the work of Margaret Archer, Anthony Giddens, and Friedrich Hayek. Emergence, change, reproduction, time, agency, power, and knowledge are themes which can be read in these …


Enhancing Web Services Description And Discovery To Facilitate Composition, Preeda Rajasekaran, John A. Miller, Kunal Verma, Amit P. Sheth Jul 2004

Enhancing Web Services Description And Discovery To Facilitate Composition, Preeda Rajasekaran, John A. Miller, Kunal Verma, Amit P. Sheth

Kno.e.sis Publications

Web services are in the midst of making the transition from being a promising technology to being widely used in the industry. However, most efforts to use Web services have been manual, thus slowing down the ever changing and dynamic businesses of today. In this paper, we contend that more expressive descriptions of Web services will lead to greater automation and thus provide more agility to businesses. We present the METEOR-S front-end tools for source code annotation and semantic Web service description generation. We also present WSDL-S, a language created for incorporating semantic descriptions in the industry wide accepted WSDL, …


Workflow Management Systems And Erp Systems: Differences, Commonalities, And Applications, Jorge Cardoso, Robert P. Bostrom, Amit P. Sheth Jul 2004

Workflow Management Systems And Erp Systems: Differences, Commonalities, And Applications, Jorge Cardoso, Robert P. Bostrom, Amit P. Sheth

Kno.e.sis Publications

Two important classes of information systems, Workflow Management Systems(WfMSs) and Enterprise Resource Planning (ERP) systems, have been used to support e-business process redesign, integration, and management. While both technologies can help with business process automation, data transfer, and information sharing, the technological approach and features of solutions provided by WfMS and ERP are different. Currently, there is a lack of understanding of these two classes of information systems in the industry and academia, thus hindering their effective applications. In this paper, we present a comprehensive comparison between these two classes of systems. We discuss how the two types of systems …


Learning Mixture Models With The Regularized Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao Jul 2004

Learning Mixture Models With The Regularized Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao

Kno.e.sis Publications

This paper presents a new approach to estimating mixture models based on a recent inference principle we have proposed: the latent maximum entropy principle (LME). LME is different from Jaynes' maximum entropy principle, standard maximum likelihood, and maximum a posteriori probability estimation. We demonstrate the LME principle by deriving new algorithms for mixture model estimation, and show how robust new variants of the expectation maximization (EM) algorithm can be developed. We show that a regularized version of LME (RLME), is effective at estimating mixture models. It generally yields better results than plain LME, which in turn is often better than …


Discovery Of Web Services In A Federated Registry Environment, Kaarthik Sivashanmugam, Kunal Verma, Amit P. Sheth Jul 2004

Discovery Of Web Services In A Federated Registry Environment, Kaarthik Sivashanmugam, Kunal Verma, Amit P. Sheth

Kno.e.sis Publications

The potential of a large scale growth of private and semi-private registries is creating the need for an infrastructure which can support discovery and publication over a group of autonomous registries. Recent versions of UDDI have made changes to accommodate interactions between distributed registries. In this paper, we discuss METEOR-S Web service Discovery Infrastructure, which provides an ontology-based infrastructure to access a group of registries that are divided based on business domains and grouped into federations. We also discuss how Web service discovery is carried out within a federation.

The Infinite Plasticity Of The Digital: Posthuman Possibilities, Embodiment And Technology In William Gibson's Interstitial Trilogy, Tama Leaver Jul 2004

The Infinite Plasticity Of The Digital: Posthuman Possibilities, Embodiment And Technology In William Gibson's Interstitial Trilogy, Tama Leaver

Reconstruction: Studies in Contemporary Culture

[Editors' Introduction]

Ever since William Gibson coined the term cyberspace in his debut novel Neuromancer, his work has been seen by many as a yardstick for postmodern and, more recently, posthuman possibilities. This article critically examines Gibson's second trilogy (Virtual Light, Idoru and All Tomorrow's Parties), focusing on the way digital technologies and identity intersect and interact, with particular emphasis on the role of embodiment. Using the work of Donna Haraway, Judith Butler and N. Katherine Hayles, it is argued that while William Gibson's second trilogy is infused with posthuman possibilities, the role of embodiment is …


Wireless Local Number Portability: New Rules Will Have Broad Effects, Stephen M. Kessing Jun 2004

Wireless Local Number Portability: New Rules Will Have Broad Effects, Stephen M. Kessing

Duke Law & Technology Review

After a delay of over seven years, wireless local number portability rules ("WLNP") finally went into effect on November 24, 2003. These rules, promulgated by the Federal Communications Commission, allow wireless subscribers to change service providers within a given location while retaining the same phone number. The rules also allow consumers to transfer a land-based telephone number to a cellular provider. These new choices will likely have a significant impact on the wireless industry and increase competition in an already intense playing field. This iBrief provides a summary of the new rules, looks at the history and litigation, and predicts …

Sweto: Large-Scale Semantic Web Test-Bed, Boanerges Aleman-Meza, Chris Halaschek, Amit P. Sheth, I. Budak Arpinar, Gowtham Sannapareddy

Kno.e.sis Publications

The emergent Semantic Web community needs a common infrastructure for testing the scalability and quality of new techniques and software which use machine processable data. Since ontologies are a centerpiece of most approaches, we believe that for an accurate evaluation of tools for quality, scalability and performance, the research community needs a freely available ontology with a large description base. If the use of tools is to be for advanced semantic applications, such as those in business intelligence and national security, then instances in the knowledge base should be highly interconnected. Thus, we propose and describe a Semantic WEb Technology …


Some Practical Points On Organizing Etd Consortia, Silvia B. Southwick, Ana Pavani Jun 2004

Some Practical Points On Organizing Etd Consortia, Silvia B. Southwick, Ana Pavani

Library Faculty Research

Electronic Thesis and Dissertation (ETD) digital libraries are being developed worldwide. Higher education organizations commonly collaborate in these efforts by forming consortia. Some of the existing consortia are at the national level while others are at regional levels. NDLTD (Networked Digital Library for Thesis and Dissertations) is an initiative that is creating an international consortium which includes organizations or other ETD consortia in various countries. Consortia are important because they create an opportunity to collaborate, to share experiences, and to establish or adopt standards that guarantee interoperability among participant ETD digital libraries. However, developing consortia is challenging since it requires …


A Library’S Integrated Online Library System: System Assessment And New Hardware Implementation, Jason Vaughan Jun 2004

A Library’S Integrated Online Library System: System Assessment And New Hardware Implementation, Jason Vaughan

Library Faculty Research

For more than a decade, a consortium of academic libraries in southern Nevada has shared a central integrated online library system (IOLS), Innovative Interfaces’ Innopac (Innovative when referring to the vendor, Innopac when referring to the software). At present, this consortium includes the University of Nevada, Las Vegas (UNLV) (both the main university library system and the UNLV law library), the Community College of Southern Nevada, Nevada State College, and the Desert Research Institute. The last central-site server was purchased and installed in 1997. In the four intervening years, tremendous growth occurred with the system, necessitating a hardware upgrade. Prior …

Meteor-S Web Service Annotation Framework, Abhijit A. Patil, Swapna A. Oundhakar, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

The World Wide Web is emerging not only as an infrastructure for data, but also for a broader variety of resources that are increasingly being made available as Web services. Relevant current standards like UDDI, WSDL, and SOAP are in their fledgling years and form the basis of making Web services a workable and broadly adopted technology. However, realizing the fuller scope of the promise of Web services and associated service oriented architecture will requite further technological advances in the areas of service interoperation, service discovery, service composition, and process orchestration. Semantics, especially as supported by the use of ontologies, …


Sempl: A Semantic Portal, Matthew Perry, Eric Stiles May 2004

Sempl: A Semantic Portal, Matthew Perry, Eric Stiles

Kno.e.sis Publications

Semantic Web technology is intended for the retrieval, collection, and analysis of meaningful data with significant automation afforded by machine understandability of data [1]. As one illustration of semantic web technology in action, we present SEMPL, a semantic web portal for the Large Scale Distributed Information Systems lab (LSDIS) at the University of Georgia. SEMPL, which is powered by a state of the art commercial system, Semagix Freedom [7], uses an ontology-driven approach to provide semantic browsing, linking, and contextual querying of content within the portal. By using the ontology based information integration technique, SEMPL can specify the context of …


Indexing Genomic Databases, Gina Cooper, Michael L. Raymer, Travis E. Doom, Dan E. Krane, Natsuhiko Futamura May 2004

Indexing Genomic Databases, Gina Cooper, Michael L. Raymer, Travis E. Doom, Dan E. Krane, Natsuhiko Futamura

Kno.e.sis Publications

Current biological sequence comparison tools utilize full database searches to find approximate matches between a database and a query. A new approach to sequence comparisons can be performed by indexing the database using a novel indexing scheme. An indexed scheme can immediately eliminate highly mismatched sequences thereby improving performance and accuracy. iBlast is proposed as an indexed version of BLAST. In its initial implementation, iBlast uses a sequence-based index to catalog genomic databases in an NCR Teradata RDBMS. Several types of indexes and querying methods are explored to determine the most efficient solution utilizing the parallel nature of the Teradata …


Independence Of Nations And The Role Of Libraries: The American Library System As The Stakeholder For Freedom Of Information, Lana Zink Apr 2004

Independence Of Nations And The Role Of Libraries: The American Library System As The Stakeholder For Freedom Of Information, Lana Zink

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

The nations of the world community are independent of each other. There is no higher authority to bring together like and unlike nations for the betterment of world order. Each nation stands alone. It is realized, even in America, that international affairs dictate there is no one moral code common to all people and to all governments of the world. Political order in the world community depends upon an independence of nations, but an independence that recognizes a moral, reasoned mind. The so-called American library system plays a role in the assurances toward tempered, human behavior at the international …


A First In Africa: Implementation Of Metalib And Sfx At The Cape Technikon Library, Deborah Becker Apr 2004

A First In Africa: Implementation Of Metalib And Sfx At The Cape Technikon Library, Deborah Becker

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

The Cape Technikon was the first member of the CALICO consortium of five academic libraries in the Western Cape, South Africa to implement Metalib and SFX technology.

Metalib is a library portal that enables users to search multiple database sources simultaneously, while SFX provides “context-sensitive” linking. This article examines local technical and staffing issues, managing the implementation process using the traditional African principles of ubuntu and batho pele (putting “people first”), and the marketing campaign leading to the final launch of the product.

The use of questionnaires at various stages of the implementation process to evaluate users’ opinions and …


Quality Of Service For Workflows And Web Service Processes, Jorge Cardoso, Amit P. Sheth, John A. Miller, Jonathan Arnold, Krzysztof J. Kochut Apr 2004

Quality Of Service For Workflows And Web Service Processes, Jorge Cardoso, Amit P. Sheth, John A. Miller, Jonathan Arnold, Krzysztof J. Kochut

Kno.e.sis Publications

Workflow management systems (WfMSs) have been used to support various types of business processes for more than a decade now. In workflows or Web processes for e-commerce and Web service applications, suppliers and customers define a binding agreement or contract between the two parties, specifying quality of service (QoS) items such as products or services to be delivered, deadlines, quality of products, and cost of services. The management of QoS metrics directly impacts the success of organizations participating in e-commerce. Therefore, when services or products are created or managed using workflows or Web processes, the underlying workflow engine must accept …

In Medias Res: An Ordinary Revolution, Part Ii, Davin Heckman

Reconstruction: Studies in Contemporary Culture

[First paragraph]

A series of relatively recent events has forced me to reconsider the practice of publishing and the art of media-making. As Reconstruction approaches the completion of its fourth year of publication and begins a massive editorial reorganization [2], I have been undergoing a reorganization of my own -- a job search, manuscripts in search of publishers, a virtual conference to help plan, a dissertation defended, and a new baby at home. In addition to this, there are journal issues to complete, submissions to review, edits to make, reviews to write, and, now, an editorial to create. I am, …

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Mike Gunderloy, creator of Factsheet 5, and co-author of The World of Zines, offers the following definition of perzines:

A personal zine, or perzine, is the most intimate kind of zine. It allows the editor/writer many freedoms, not the least of which is spouting off about anything or nothing-in-particular without worrying about editorial policies and other rules of regimented periodicals. It's also a way of corresponding with any number of people simultaneously while maintaining an aura of intimacy and friendship. And something else to remember when you're reading (or writing) a perzine -- because this intimacy …


From Butler To Buffy: Notes Towards A Strategy For Identity Analysis In Contemporary Television Narrative, Rob Cover Apr 2004

From Butler To Buffy: Notes Towards A Strategy For Identity Analysis In Contemporary Television Narrative, Rob Cover

Reconstruction: Studies in Contemporary Culture

[First paragraph]

Given the increasing significance of questions of identity, subjectivity and selfhood in contemporary postmodern western cultures, it is important to begin acknowledging how these questions are reflected in contemporary media and television and to develop new strategies by which to analyse television characters in terms of identity and subjectivity. The scope for analysing television series' characterizations through recent postmodern and poststructuralist theories of non-essentialist, non-foundationalist subject/identity performativity has not yet been considerably explored. It is my contention here, however, that such a method both reflects the representation of self and identity transformation in new television series as well …

Cultural Literacy And The Field Of The Media, Tony Schirato, Jen Webb Apr 2004

Cultural Literacy And The Field Of The Media, Tony Schirato, Jen Webb

Reconstruction: Studies in Contemporary Culture

[First paragraph]

This paper is concerned with the notion of cultural literacy, specifically with regard to the media, and focuses on two interrelated questions. First, what do we mean by the term cultural literacy, and how can this term be extended and applied to the field, texts and practices of the media? Second, what is it about the place and function of the media in the contemporary world that requires us (as citizens, educators or audiences) to be culturally and media literate?


The Next Step In Scholarly Communication: Is The Traditional Journal Dead?, Jeanne Galvin Apr 2004

The Next Step In Scholarly Communication: Is The Traditional Journal Dead?, Jeanne Galvin

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Electronic journals have been applauded as a solution to the serials pricing crisis, a step toward environmentally responsible behavior and a means for scholars to expedite and expand their modes of communication. On the other hand, until fairly recently some scholars regarded electronic journals as ephemeral and inaccessible to all but the technologically proficient. As rising prices force libraries to cancel subscriptions each year and publication delays slow scholarly communication and academic careers, electronic journals seem to offer some promise. The article will review the recent advances made by electronic journals and the current challenges remaining for scholarly communication.

Certainly the Internet has revolutionized our perception of information and information access. Information is everywhere on the Internet, existing in large quantities and continuously being created and revised. Finding information on the Internet has been described as drinking from a fire hose. As lawyers, how can we assess how much and what type of reliable information is available on the Internet for legal research? One of the most important tasks of this Internet Legal Research CLE is to inform you of exactly what types of major legal resources you can expect to find on the Internet and to equip you …
