Beyond Sawsdl - A Game Plan For Broader Adoption Of Semantic Web Services, Amit P. Sheth

Kno.e.sis Publications

After a flurry of research activities led by the OWL-S, WSMO, SWSF, and WSDL-S groups, we now have taken the first concrete steps toward building a Semantic Web Services (SWS) based solution, in the form of a W3C candidate recommendation SAWSDL [http://www.w3.org/2002/ws/sawsdl/], associated tools and use cases, and initial applications [1]. Where do we go from here? Researchers among us may be fully convinced of the importance and benefit of adding semantics to Web services and impatient to see their research translated into technologies and adapted for real use. However, I believe we may need to be patient and do …

A Unified Approach To Retrieving Web Documents And Semantic Web Data, Trivikram Immaneni, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The Semantic Web seems to be evolving into a property-linked web of RDF data, conceptually divorced from (but physically housed in) the hyperlinked web of HTML documents. We discuss the Unified Web model that integrates the two webs and formalizes the structure and the semantics of interconnections between them. We also discuss the Hybrid Query Language which combines the Data and Information Retrieval techniques to provide a convenient and uniform way to retrieve data and documents from the Unified Web. We present the retrieval system SITAR and some preliminary results.

Scrutinizing Cataloging Copy, Julie Banks

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

Abstract

In order to determine if cataloging copy today is as acceptable as past copy, the researcher compared additions and corrections to a random sample of monographic copy that corresponded to the books that went through the cataloging department during 2006 at Southeast Missouri State University with previously reported editing work from several libraries. The outcome was that more editing was required today, but it was not possible to identify whether this was due to the rapidly changing cataloging environment or to the higher level of editing performed.

Developing A Web-Based Evaluation Tool For Purchasing Electronic Resources: A Librarian-Faculty-Student Partnership, Peter Linberger, Lori Jean Fielding, Frank J. Bove

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

Introduction

“While the principles of collection development, which were developed in the world of print publications, do not change radically with new publishing technologies, methods of decision making and specific selection guidelines must be adjusted significantly to incorporate new publishing formats” (Demas).

The goals of acquiring and maintaining a good collection of resources that directly benefit teaching and research at a university are important ones. It is nearly impossible for most library budgets to acquire every available electronic research database and the task of deciding which of these resources to purchase has been mostly left to librarians. In order to …

What Students Do When They Study In The Library: Using Ethnographic Methods To Observe Student Behavior, Doug Suarez

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

Abstract

How do we know what students are really doing in the library when they are studying? This paper reports on a study that used qualitative methods to assess what students were doing during the winter term at Brock University. The goals were to try and establish if they were engaged in their studies when using the library and to see if the library nurtured academic engagement in its study areas.

A Faculty Led Response To The Crisis In Scholarly Communications, Michael Boock

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

Abstract

Oregon State University’s recent response to the crisis in scholarly communications recognizes that teaching faculty must be involved in communicating an appropriate response to their faculty colleagues. As authors, editors, and peer reviewers, direct faculty action can encourage publishers to lower costs and can enhance the availability of research. The author discusses the work of a faculty-led task force that communicates information about unsustainable journal costs to faculty peers and the actions that can be taken to counteract this trend. In particular, the author discusses the use of academic unit publication reviews to effectively communicate journal cost variations to …

Sa-Rest: Semantically Interoperable And Easier-To-Use Services And Mashups, Amit P. Sheth, Karthik Gomadam, Jonathan Lathem

Kno.e.sis Publications

Services based on the representational state transfer (REST) paradigm, a lightweight implementation of a service-oriented architecture, have found even greater success than their heavyweight siblings, which are based on the Web Services Description Language (WSDL.) and SOAP. By using XML-based messaging, RESTful services can bring together discrete data from different services to create meaningful data sets; mashups such as these are extremely popular today.

Measuring Inconsistency For Description Logics Based On Paraconsistent Semantics, Yue Ma, Guilin Qi, Pascal Hitzler, Zuoquan Li

Computer Science and Engineering Faculty Publications

In this paper, we present an approach for measuring inconsistency in a knowledge base. We first define the degree of inconsistency using a four-valued semantics for the description logic ALC. Then an ordering over knowledge bases is given by considering their inconsistency degrees. Our measure of inconsistency can provide important information for inconsistency handling.

The Regionalization Of Global News: A Case Study Of Cnn Interactive, Margaretha Geertsema-Sligh

Scholarship and Professional Work - Communication

The Cable News Network is often used as the prime example of a global news service. With bureaus and correspondents all around the world, CNN crosses traditional national boundaries. However, in essence, CNN remains an American company through its ownership and its Atlanta location. It also follows a news style that is typically Wester. Yet, CNN has had much success with both its international broadcasting services and its online service, offered by CNN interactive.

The aim of thhis paper is to take a closer look at CNN's presence on the Internet. This project is theoretically informed by discourses of globalization, …

Semantic Matchmaking Of Web Resources With Local Closed-World Reasoning, Stephan Grimm, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Ontology languages like OWL allow for semantically rich annotation of resources (e.g., products advertised at on-line electronic marketplaces). The description logic (DL) formalism underlying OWL provides reasoning techniques that perform match-making on such annotations. This paper identifies peculiarities in the use of DL inferences for matchmaking that derive from OWL's open-world semantics, analyzes local closed-world reasoning for its applicability to matchmaking, and investigates the suitability of two nonmonotonic extensions to DL, autoepistemic DLs and DLs with circumscription, for local closed-world reasoning in the matchmaking context. An elaborate example of an electronic marketplace for PC product catalogs from the e-commerce domain …

From “Glycosyltransferase” To “Congenital Muscular Dystrophy”: Integrating Knowledge From Ncbi Entrez Gene And The Gene Ontology, Satya S. Sahoo, Kelly Zeng, Olivier Bodenreider, Amit P. Sheth

Kno.e.sis Publications

Entrez Gene (EG), Online Mendelian Inheritance in Man (OMIM) and the Gene Ontology (GO) are three complementary knowledge resources that can be used to correlate genomic data with disease information. However, bridging between genotype and phenotype through these resources currently requires manual effort or the development of customized software. In this paper, we argue that integrating EG and GO provides a robust and flexible solution to this problem. We demonstrate how the Resource Description Framework (RDF) developed for the Semantic Web can be used to represent and integrate these resources and enable seamless access to them as a unified resource. …

What, Where And When: Supporting Semantic, Spatial And Temporal Queries In A Dbms, Matthew Perry, Amit P. Sheth, Farshad Hakimpour, Prateek Jain

Kno.e.sis Publications

Spatial and temporal data are critical components in many applications. This is especially true in analytical domains such as national security and criminal investigation. The outcome of the analytical process in these applications often hinges on uncovering and analyzing complex relationships between disparate people, places and events. Fundamentally new query operators based on the graph structure of Semantic Web data models, such as semantic associations, are proving useful in these applications. However, these analysis mechanisms are primarily intended for thematic relationships. We describe a framework built around the RDF metadata model for analysis of thematic, spatial and temporal relationships between …

Evolution And Maintenance Of Frequent Pattern Space When Transactions Are Removed, Mengling Feng, Guozhu Dong, Jinyan Li, Yap-Peng Tan, Limsoon Wong

Kno.e.sis Publications

This paper addresses the maintenance of discovered frequent patterns when a batch of transactions are removed from the original dataset. We conduct an in-depth investigation on how the frequent pattern space evolves under transaction removal updates using the concept of equivalence classes. Inspired by the evolution analysis, an effective and exact algorithm TRUM is proposed to maintain frequent patterns. Experimental results demonstrate that our algorithm outperforms representative state-of-the-art algorithms.

The Digital Divide, Chad Raphael

Communication

Many have argued that inequalities of access to the Internet in an information-driven society pose a serious social problem and that public investment is needed to solve it. Others contend that the digital divide is a minor concern that will resolve itself without government involvement and spending. The positions we take on this debate depend upon our understanding of how new technologies spread throughout society, whether we think Internet access is a frill or a necessity, and our vision of whether government can and ought to help broaden access.

Turn-Taking And The Local Management Of Conversation In A Highly Simultaneous Computer-Mediated Communication System, Jeffrey F. Anderson, Fred K. Beard, Joseph B. Walther

Faculty Articles

Ongoing inquiry in communication technology research includes the questions of whether and how users adapt communication to the relatively restricted codes provided by text-based computer-mediated communication (CMC). This study proposes that adaptations may be affected by the level of simultaneity in messaging that CMC systems afford users. This suggestion is examined through an analysis of the particular conversational management strategies afforded by a fully synchronous computer-mediated communication system in which message transmission is keystroke-by-keystroke. Conversation analyses performed on the transcript of a three-person online conversation suggest several conclusions: Despite the novelty of the system, the CMC users appropriated and adapted …

Blogging The Other: Representations Of The Australian Islamic Diaspora, Judith Elund

Theses : Honours

Recent events have seen an increased focus on Islam and Muslims throughout the world. In Western nations, this focus has often turned into fear and the demonisation of an 'other' that is regularly misunderstood and misrepresented, further exacerbating tensions between the West and Islam. International terrorist activities, such as the London bombings of July 7, 2005 have seen an increase in fear of Muslims and of potential terrorism on our shores, ensuring Muslim issues have become a major focus in Australian news. Taking 7/7 as an example, this paper supplements recent studies in exploring how Australian news media position Muslims …

Digital Watermarking And Self-Authentication Using Chirp Coding, Jonathan Blackledge

Articles

This paper discusses a new approach to ‘watermarking’ digital signals using linear frequency modulated or ‘chirp’ coding. The principles underlying this approach are based on the use of a matched filter to provide a reconstruction of a chirped code that is uniquely robust, i.e. in the case of very low signal-to-noise ratios.

Chirp coding for authenticating data is generic in the sense that it can be used for a range of data types and applications (the authentication of speech and audio signals, for example). The theoretical and computational aspects of the matched filter and the properties of a chirp are …

Virtual Worlds: A New Paradigm For Advertising?, Nigel Devenport

Theses : Honours

This thesis explores the new paradigms that are emerging as advertising encounters the Internet. The area that I explore is the convergence of corporate advertising and the online game, Second Life. The thesis takes as its starting point the economic and social/cultural history of advertising. I examine both Marxist and cultural theories of advertising, in order to properly understand the paradigm shifts of the past. I also investigate the effect that technological change has had on the practice of advertising. Having established an historical framework I· then turn to the current state of the advertising market, as it is defined …
