Traveling The Semantic Web Through Space, Time, And Theme, Amit P. Sheth, Matthew Perry

Kno.e.sis Publications

In this installment of Semantics and Services, we further develop the idea of spatial, temporal, and thematic (STT) processing of semantic Web data and describe the Web infrastructure needed to support it. Starting from Ramesh Jain's vision of the EventWeb as a view of what's possible with a Web that better accommodates all three dimensions of event-related information (thematic, spatial, and temporal), we outline the architecture needed to support it and current research that aims to realize it.

Back To The Future: The Emergence Of Contrasting European And Us Approaches To Digital Radio, Brian O'Neill

Conference Papers

Digital radio has been in development for over 25 years and yet is no nearer a point of successful adoption. This paper explores the emergence of contrasting European and American approaches to digital radio. The most established of these, Eureka-147 or Digital Audio Broadcasting (DAB), which originated in Europe, is contrasted with the so-called IBOC or /HD Radio approach, as alternative collective conceptualizations of how technology can bridge contemporary broadcasting practice to an ̳imagined‘ digital future. Drawing on the concept of ̳symptomatic technology‘ (Williams 1974), DAB‘s origins in European R&D policy of the 1980s and its affinity with established European …

Approximate Owl Instance Retrieval With Screech, Pascal Hitzler, Markus Krotzsch, Sebastian Rudolph, Tuvshintur Tserendorj

Computer Science and Engineering Faculty Publications

With the increasing interest in expressive ontologies for the Semantic Web, it is critical to develop scalable and efficient ontology reasoning techniques that can properly cope with very high data volumes. For certain application domains, approximate reasoning solutions, which trade soundness or completeness for increased reasoning speed, will help to deal with the high computational complexities which state of the art ontology reasoning tools have to face. In this paper, we present a comprehensive overview of the SCREECH approach to approximate instance retrieval with OWL ontologies, which is based on the KAON2 algorithms, facilitating a compilation of OWL DL TBoxes …

Is The Internet A Viable Threat To Representative Democracy?, David M. Thompson

Duke Law & Technology Review

The Internet, despite its relatively recent advent, is critical to millions of Americans’ way of life. Although the Internet arguably opens new opportunities for citizens to become more directly involved in their government, some scholars fear this direct involvement poses a risk to one of the Constitution’s most precious ideals: representative democracy. This iBrief explores whether the constitutional notion of representation is vulnerable to the Internet’s capacity to open new vistas for a more direct democracy by analyzing statistics and theories about why voters in the United States do or do not vote and by examining the inherent qualities of …

Ontology Driven Semantic Provenance For Heterogeneous Bionomics Experimental Data, Satya S. Sahoo, Michael L. Raymer, Cory Andrew Henson, Amit P. Sheth, William S. York

Kno.e.sis Publications

Scientific experimental data generated by all the bionomic technologies is characterized by heterogeneity in its representation formats, constituents, and generation processes and, therefore, also in its usage. Using the proteomics domain we demonstrate the important role of provenance information o manage, interpret and analyze experimental data. We present a novel approach that employs an ontology as a knowledge model to automatically create semantic provenance information for high-throughput mass spectrometry (MS) data in the glycoproteomics domain. The Semantic Provenance Annotation of Data in protEomics (SPADE) implementation is based on the ProPreO ontology, a large-process ontology ( ~500 classes, 40 named relationships …

The internet is a major communication channel for universities. It makes sense to insure that a Web presence of a university is representative of the university's brand and is consistent throughout all Web sites within the university. This project researches and develops Web design tools that can provice standarized resources to Web designers, specifically for California State University, San Bernardino (CSUSB).

Cheap Boolean Role Constructors For Description Logics, Sebastian Rudolph, Markus Krotzsch, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We investigate the possibility of incorporating Boolean role constructors on simple roles into some of today's most popular description logics, focussing on cases where those extensions do not increase complexity of reasoning. We show that the expressive DLs SHOIQ and SROIQ, serving as the logical underpinning of OWL and the forthcoming OWL 2, can accommodate arbitrary Boolean expressions. The prominent OWL-fragment SHIQ can be safely extended by safe role expressions, and the tractable fragments EL++ and DLP retain tractability if extended by conjunction on roles, where in the case of DLP the restriction on role simplicity can even be discarded.

Public Service In The Information Age: A Study Of E-Government In Taiwan, T. Y. Lau, Kevin Y. Wang, David Atkin

Scholarship and Professional Work - Communication

This article reviews the literature on e-government and discusses policy implications stemming from e-government initiatives in Taiwan. Drawing from evaluation frameworks established in previous research, this study surveys the content of 62 websites maintained by the local, secondary and central government. Study findings suggest that, while Taiwan has made significant progress in deploying e-government initiatives across different administrative levels-especially in delivering a single service window model providing one-stop service for citizens and businesses-the technology's overall implementation is hampered by operational inconsistencies at the local level and differential access across the population. The article argues that to fully realise the potential …

Mobile Semantic Computing, Karthik Gomadam, Anupam Joshi, Amit P. Sheth

Kno.e.sis Publications

We propose to organize a special session on research in the intersection of mobile computing, the Semantic Web and Web services.

This session will examine how the research in these areas can serve as a foundation for new architectural and communication paradigms that can enhance service creation, distribution, discovery, integration and utilization in distributed and ubiquitous environments. Some of the initial areas that our early research have highlighted are :

1. Semantic annotation of data in bandwidth constrained environments such as mobile networks to promote efficient bandwidth utilization
2. Possibilities of using microformats such as RDFa and opportunities that can be explored …

Unsupervised Discovery Of Compound Entities For Relationship Extraction, Cartic Ramakrishnan, Pablo N. Mendes, Shaojun Wang, Amit P. Sheth

Kno.e.sis Publications

In this paper we investigate unsupervised population of a biomedical ontology via information extraction from biomedical literature. Relationships in text seldom connect simple entities. We therefore focus on identifying compound entities rather than mentions of simple entities. We present a method based on rules over grammatical dependency structures for unsupervised segmentation of sentences into compound entities and relationships. We complement the rule-based approach with a statistical component that prunes structures with low information content, thereby reducing false positives in the prediction of compound entities, their constituents and relationships. The extraction is manually evaluated with respect to the UMLS Semantic Network …

Reasoning In Circumscriptive Alco, Stephan Grimm, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Non-monotonic extensions of description logics (DLs) allow for default and local closed-world reasoning and are an acknowledged desired feature for applications, e.g. in the Semantic Web. A recent approach to such an extension is based on McCarthy's circumscription, which rests on the principle of minimising the extension of selected predicates to locally close off dedicated parts of a domain model. While decidability and complexity results have been established in the literature, no practical algorithmisation for circumscriptive DLs has been proposed so far. In this paper, we present a tableaux calculus that can be used as a sound and complete decision …

Expressive Tractable Description Logics Based On Sroiq Rules, Markus Krotzsch, Sebastian Rudolph, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We introduce description logic (DL) rules as a new rule-based formalism for knowledge representation in DLs. As a fragment of the Semantic Web Rule Language SWRL, DL rules allow for a tight integration with DL knowledge bases. In contrast to SWRL, however, the combination of DL rules with expressive description logics remains decidable, and we show that the DL SROIQ - the basis for the ongoing standardisation of OWL 2 - can completely internalise DL rules. On the other hand, DL rules capture many expressive features of SROIQ that are not available in simpler DLs yet. While reasoning in SROIQ …

Technology-Aided Participative Methods In Environmental Assessment: An International Perspective, Ainhoa Gonzalez, Alan Gilmer, Ronan Foley, John Sweeney, John Fry

Articles

Provisions for citizen involvement in the assessment of potential environmental effects of certain plans, programmes and projects are present in current legislation. An international survey revealed that public participation is common practice in European and some other countries worldwide. However, a number of issues are observed to affect public involvement in EIA/SEA processes and expert opinion differs when evaluating the effectiveness of existing participative methods. Results suggest that technology-aided methods can improve traditional participation processes. In particular, GIS has the potential to increase community knowledge and enhance involvement by communicating information more effectively. Variable accessibility to technology and data quality …

A Coherent Well-Founded Model For Hybrid Mknf Knowledge Bases, Matthias Knorr, Jose Julio Alferes, Pascal Hitzler

Computer Science and Engineering Faculty Publications

With the advent of the Semantic Web, the question becomes important how to best combine open-world based ontology languages, like OWL, with closed-world rules paradigms. One of the most mature proposals for this combination is known as Hybrid MKNF knowledge bases [11], which is based on an adaptation of the stable model semantics to knowledge bases consisting of ontology axioms and rules. In this paper, we propose a well-founded semantics for such knowledge bases which promises to provide better efficiency of reasoning, which is compatible both with the OWL-based semantics and the traditional well-founded semantics for logic programs, and which …

Approximate Owl-Reasoning With Screech, Tuvshintur Tserendorj, Sebastian Rudolph, Markus Krotzsch, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Applications of expressive ontology reasoning for the Semantic Web require scalable algorithms for deducing implicit knowledge from explicitly given knowledge bases. Besides the development of more effi- cient such algorithms, awareness is rising that approximate reasoning solutions will be helpful and needed for certain application domains. In this paper, we present a comprehensive overview of the Screech approach to approximate reasoning with OWL ontologies, which is based on the KAON2 algorithms, facilitating a compilation of OWL DL TBoxes into Datalog, which is tractable in terms of data complexity. We present three different instantiations of the Screech approach, and report on …

Global Media, Communication Technology, And The War On Terror, James Castonguay

Communication, Media & The Arts Faculty Publications

From the telegraph, radio, film, and television to the Internet and mobile satellite networks, media and communication technologies have been integral to the waging and representation of war. Always eager to improve communications, surveillance, and weapons systems, military institutions have funded and developed new communication technologies and media since at least the 19th century, and journalism and entertainment have long been central to governments’ propaganda efforts. In the current context of the Iraq War and the “war on terror,” most accounts of international communication equate media with news (ignoring other genres) and often neglect the crucial role that audiences and …

Online Forums As An Arena For Political Discussions: What Politicians And Activists Can Learn From Teachers, Kevin Y. Wang

Scholarship and Professional Work - Communication

This paper discusses the use of online discussion forums in various “e-democratic” practices in light of the lessons learned from the field of education. Informed by a conceptual framework drawn from the role of public sphere in electronic democracy and the ideal learning conditions of a computer-mediated communication environment, the author analyzed two discussion forums maintained by a government and a civil society group. Results suggest that, in both cases, online discussion forums only reflect a few elements of effective online learning and therefore, have yet to reach their full potentials. Implications for future research are discussed.

Media Literacy In The Digital Age: Implications For Scholars And Students, Barbara R. Burke

Communication, Media, and Rhetoric Publications

Advocates of the practice assert becoming media literate may be the way to take control, and to be better able to identify and control the borders between the real world and the world manufactured by the media. This paper embraces this assertion, and suggests advocating expanding our understandings of media literacy, and creating new strategies for analysis and critique of New Media. To make this argument, the paper will describe American attempts at shaping media education to foster media literacy. Then, a comparison between Campbell’s system and Federov’s modules of media literacy will be offered. Finally, two new elements of …

Outside The Frame: Towards A Phenomenology Of Texts And Technology, Anthony Crisafi

Electronic Theses and Dissertations

The subject of my dissertation is how phenomenology can be used as a tool for understanding the intersection between texts and technology. What I am suggesting here is that, specifically in connection with the focus of our program in Texts and Technology, there are very significant questions concerning how digital communications technology extends our humanity, and more importantly what kind of epistemological and ontological questions are raised because of this. There needs to be a coherent theory for Texts and Technology that will help us to understand this shift, and I feel that this should be the main focus for …

New Liaison Librarians: Factors Influencing Confidence Levels And The Type Of Activities Undertaken, Ramirose Attebury, Sara Holder

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

Abstract

Although library literature related to liaison work is not uncommon, most of what has been written takes the form of advice to new liaisons or else describes liaison program implementation and evaluation. This study seeks to identify what types of activities liaison librarians are employing nationwide and what factors influence the decision to undertake these activities. It also investigates what factors affect self-reported confidence levels of new liaison librarians.
