Data Processing In Space, Time, And Semantics Dimensions, Farshad Hakimpour, Boanerges Aleman-Meza, Matthew Perry, Amit P. Sheth

Kno.e.sis Publications

This work presents an experimental system for data processing in space, time and semantics dimensions using current Semantic Web technologies. The paper describes how we obtain geographic and event data from Internet sources and also how we integrate them into an RDF store. We briefly introduce a set of functionalities in space, time and semantics dimensions. These functionalities are implemented based on our existing technology for main-memory based RDF data processing developed in the LSDIS Lab. A number of these functionalities are exposed as REST Web services. We present two sample client side applications that are developed using a combination …

Social Issues In America, Stephen D. Cooper

Communications Faculty Research

One of the more contentious issues in social science at this time is the question of media bias. Both the scholarly and popular literature are thick with writings on this topic, yet for all the interest in it and work devoted to it we are far from a consensus on how media bias can be defined, conceptualized, or researched. Ironically enough, many writings on the subject of media bias do take the position that the news content distributed to the public fails, in one respect or another, to accurately and fairly represent real events, issues, personalities, and situations. Studies differ …

Semi-Supervised Conditional Random Fields For Improved Sequence Segmentation And Labeling, Feng Jiao, Shaojun Wang, Chi-Hoon Lee, Russell Greiner, Dale Schuurmans

Kno.e.sis Publications

We present a new semi-supervised training procedure for conditional random fields (CRFs) that can be used to train sequence segmentors and labelers from a combination of labeled and unlabeled training data. Our approach is based on extending the minimum entropy regularization framework to the structured prediction case, yielding a training objective that combines unlabeled conditional entropy with labeled conditional likelihood. Although the training objective is no longer concave, it can still be used to improve an initial model (e.g. obtained from supervised training) by iterative ascent. We apply our new training algorithm to the problem of identifying gene and protein …

An Investigation Of Codon Usage Bias Including Visualization And Quantification In Organisms Exhibiting Multiple Biases, Douglas W. Raiford, Travis E. Doom, Dan E. Krane, Michael L. Raymer

Kno.e.sis Publications

Prokaryotic genomic sequence data provides a rich resource for bioinformatic analytic algorithms. Information can be extracted in many ways from the sequence data. One often overlooked process involves investigating an organism’s codon usage. Degeneracy in the genetic code leads to multiple codons coding for the same amino acids. Organism’s often preferentially utilize specific codons when coding for an amino acid. This biased codon usage can be a useful trait when predicting a gene’s expressivity or whether the gene originated from horizontal transfer. There can be multiple biases at play in a genome causing errors in the predictive process. For this …

A Semantic Future For Ai, Rudi Studer, Anupriya Ankolekar, Pascal Hitzler

Computer Science and Engineering Faculty Publications

In our modern information society, people need to manage ever-increasing numbers of personal devices and conduct more of their work and activities online, often making use of heterogeneous services. The amount of information to be processed by each individual is constantly growing, making it increasingly difficult to control, channel, share and make constructive use of it. To mitigate this, computing needs to become much more human-centered, e.g. by presenting personalised information to users and by respecting personal preferences in controlling multiple devices or invoking various services. Appropriate representation of the semantics of the information and functionality of devices and services …

Assessing Library Collections Using Brief Test Methodology, Jennifer Benedetto Beals

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

Abstract

The brief test methodology was developed by Howard White as an assessment tool to determine or verify the existing strength of a library collection. The relatively quick and inexpensive procedure utilizes the Research Libraries Group’s Conspectus levels, subject expertise, and cataloging records in WorldCat. In support of the University of Tennessee Libraries’ continuing efforts to encourage resource sharing with Information Alliance partners, I developed a project with art counterparts at the University of Kentucky and Vanderbilt University. Using brief tests, I completed an assessment of each institution’s collection in the subject area of African art. The results enabled us …

Subject Librarians In The Changing Academic Library, Louise Feldman

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

Abstract

This article overviews the literature and key topics surrounding the role of subject librarianship in the evolving environment of academic libraries. Subject librarians are looked at in the context of the broad trends affecting librarianship and in the context of the traditional roles they have held in collection development, instruction, and reference. The author opened a discussion on this topic entitled, “Subject Librarians: Viable or Vanishing?” for the RUSA-CODES Dual Assignments Discussion Group at the American Library Association Midwinter Meeting in San Antonio, Texas in January of 2006.

Tiered Reference: The New Landscape Of The Frontlines, Susan Gardner

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

Introduction

When one walks into a typical academic library today, he or she is hard-pressed to see a reference librarian in plain view working at a public services desk. The well marked “reference desk” of yore, staffed by a smiling librarian and once a staple of every traditional academic library, has evolved into a less visible, more amorphous facility. Most libraries now use a new service strategy called “tiered reference,” whereby the initial reference contact point is with trained students or paraprofessionals at a general service desk. These non-librarians field all manner of questions, including directional, computing, and occasionally reference. …

Exploring The Lsu Libraries’ Virtual Reference Transcripts: An Analysis, Jenna Ryan, Alice L. Daugherty, Emily C. Mauldin

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

Abstract

Virtual reference is an important service provided by the Louisiana State University Libraries. A subcommittee within the Reference Department of Middleton Library decided to quantitatively and qualitatively review virtual reference transcripts for the 2005-2006 school year in order to assess and evaluate strengths and weaknesses of the services provided. The transcript analysis provides information reflecting how our patrons are using virtual reference and how our librarians are performing in the virtual environment.

The Use Of Scholarly Monographs In The Journal Literature Of Latin American History, Meiyolet Mendez, Karen Chapman

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

Abstract

This study explores the use of the monograph in the journal literature of Latin American history through a reference study of Hispanic American Historical Review for the years 1985, 1995 and 2005. The authors found that the use of monographs as secondary sources increased over time. Monographs in Spanish and Portuguese were heavily used, although English was the predominant language. Distribution of publication dates varied somewhat over the period, with less use of works from the previous five years in 2005. The most frequently-cited publishers were university presses. The authors concluded that the monograph continues to play a vital …

New Strategies For An Old Medium: The Weekly Radio Addresses Of Reagan And Clinton, Lori Cox Han

Political Science Faculty Articles and Research

"While a rich literature exists on presidential communications (including the public/rhetorical presidency and the presidential/press relationship), only recently have presidential scholars begun to analyze weekly radio addresses as an important primary unit of analysis (Rowland and Jones 2002; Sigelman and Whissell 2002a, 2002b). This article analyzes how the use of radio has fit into the overall development of White House communication strategies during the television age, and takes an in-depth look at how Reagan and Clinton used weekly radio addresses to communicate with both the American public and the news media. Specifically, the issues considered here include the strategy development …

Predicting Domain Specific Entities With Limited Background Knowledge, Christopher Thomas, Amit P. Sheth

Kno.e.sis Publications

This paper proposes a framework for automatic recognition of domain-specific entities from text, given limited background knowledge, e.g. in form of an ontology. The algorithm exploits several lightweight natural language processing techniques, such as tokenization and stemming, as well as statistical techniques, such as singular value decomposition (SVD) to suggest domain relatedness of unknown entities.

Using Query-Specific Variance Estimates To Combine Bayesian Classifiers, Chi-Hoon Lee, Russell Greiner, Shaojun Wang

Kno.e.sis Publications

Many of today's best classification results are obtained by combining the responses of a set of base classifiers to produce an answer for the query. This paper explores a novel "query specific" combination rule: After learning a set of simple belief network classifiers, we produce an answer to each query by combining their individual responses, using weights based inversely on their respective variances around their responses. These variances are based on the uncertainty of the network parameters, which in turn depend on the training datasample. In essence, this variance quantifies the base classifier's confidence of its response to this query. …

Clustering Similarity Comparison Using Density Profiles, Eric Bae, James Bailey, Guozhu Dong

Kno.e.sis Publications

The unsupervised nature of cluster analysis means that objects can be clustered in many ways, allowing different clustering algorithms to generate vastly different results. To address this, clustering comparison methods have traditionally been used to quantify the degree of similarity between alternative clusterings. However, existing techniques utilize only the point memberships to calculate the similarity, which can lead to unintuitive results. They also cannot be applied to analyze clusterings which only partially share points, which can be the case in stream clustering. In this paper we introduce a new measure named ADCO, which takes into account density profiles for each …

An Online Discriminative Approach To Background Subtraction, Li Cheng, Shaojun Wang, Terry Caelli

Kno.e.sis Publications

We present a simple, principled approach to detecting foreground objects in video sequences in real-time. Our method is based on an on-line discriminative learning technique that is able to cope with illumination changes due to discontinuous switching, or illumination drifts caused by slower processes such as varying time of the day. Starting from a discriminative learning principle, we derive a training algorithm that, for each pixel, computes a weighted linear combination of selected past observations with time-decay. We present experimental results that show the proposed approach outperforms existing methods on both synthetic sequences and real video data.

Importing Extended Producer Responsibility For Electronic Equipment Into The United States, Chad Raphael, Ted Smith

Communication

Extended Producer Responsibility (EPR) is a policy approach that holds manufacturers accountable for the full costs of their products at every stage in their life cycle. EPR typically involves requiring that producers take back their products at the end of their useful lives, or pay a recycling contractor to do so, thereby internalizing the costs of recycling or disposal in a manufacturer’s bottom line. When companies know that they will bear the costs of product return and recycling, they are more likely to redesign their products for easier and safer handling at each step in the life cycle. This approach …

Information Warfare: The Legal Aspects Of Using Satellites And Jamming Technologies In Propaganda Battles, Mark J. Sundahl

Law Faculty Contributions to Books

This paper examines the right of states to broadcast propaganda by satellite in times of war. In exploring this issue, the author addresses the hypothetical question of whether a state may use DBS technology to broadcast a commercial news program, such as CNN, into an enemy state in wartime as part of a larger campaign to win the support of the civilian population. The author begins by establishing that that the consent of a receiving state is required prior to such broadcasts, whether in peacetime or in times of war. This requirement of "prior consent" is the only restriction of …

Knowledge Modeling And Its Application In Life Sciences: A Tale Of Two Ontologies, Satya S. Sahoo, Christopher Thomas, Amit P. Sheth, William S. York, Samir Tartir

Kno.e.sis Publications

High throughput glycoproteomics, similar to genomics and proteomics, involves extremely large volumes of distributed, heterogeneous data as a basis for identification and quantification of a structurally diverse collection of biomolecules. The ability to share, compare, query for and most critically correlate datasets using the native biological relationships are some of the challenges being faced by glycobiology researchers. As a solution for these challenges, we are building a semantic structure, using a suite of ontologies, which supports management of data and information at each step of the experimental lifecycle. This framework will enable researchers to leverage the large scale of glycoproteomics …

Show Me What You Mean! Exploiting Domain Semantics In Ontology Visualization, Ravi Pavagada, Christopher Thomas, Amit P. Sheth, William S. York

Kno.e.sis Publications

Ontologies build the backbone for many life-sciences applications. These ontologies, however, are represented in XML based languages that are meant for machine-consumption and hence are difficult for humans to comprehend. For a meaningful visualization of these ontologies, it is important that the display of entities and relationships captures the cognitive representation of the domain as perceived by the domain experts. In this paper we present OntoVista, an ontology visualization tool that is adaptable to the needs of different domains, especially in the life sciences. While keeping the graph structures as the predominant model, we provide a semantically enhanced graph display …

Screenplay: Cinema/Videogames/Interfaces [Book Review], Marc Ouellette

English Faculty Publications

Recognizing the growing importance (at least for consumers) of video games as a popular form of narrative fiction, Geoff King and Tanya Krzywinska situate their collection, ScreenPlay: cinema/videogames/interfaces as a text which is corrective, informative and explorative. In the first case, the editors sought essays which would move the critical discourse on video games away from the more familiar but reductive debates surrounding the "effects" of video games (especially on children) and their modes of representation (especially of the female form and violence). Indeed, these have become the sine qua non of video game criticism and one feeds the other …

The Horror Is Alive: Immersion, Spectatorship, And The Cinematics Of Fear In The Survival Horror Genre, Jay Mcroy

Reconstruction: Studies in Contemporary Culture

The video game genre known as survival horror resembles contemporary horror cinema in that both increasingly popular forms of entertainment allow audiences to experience fear resulting from the development of suspense coupled with the dread and shock of encountering monstrosity. One need only note the remarkable success of next generation video game franchises like Resident Evil (1996) and Silent Hill (1999) to realize that, more than ever before, game players in their late teens and beyond long to immerse themselves within interactive nightmares that offer the kind of thrills and chills once available exclusively through horror literature and films. However, …

Cyberactivism : Public Relations In A Wired World, Shane Newton

Theses : Honours

Computer-mediated communication has revolutionised the way activist groups influence the opinion of corporations, governments and the community. It has never been so cheap or convenient to publish high-quality material to push a specific issue or cause. Activists are no longer restricted to satisfy the news values of media corporations to reach wide publics. Nor do these businesses (or governments) have any apparent advantage, despite their more economically sustainable and highly-resourced positions. Current literature is able to examine and explore how the Internet is used and the problems involved, yet much research fails to examine how these constraints and opportunities are …

The Kiosk Culture: Reconciling The Performance Support Paradox In The Postmodern Age Of Machines, Thomas Cavanagh

Electronic Theses and Dissertations

Do you remember the first time you used an Automatic Teller Machine (ATM)? Or a pay-at-the-pump gas station? Or an airline e-ticket kiosk? How did you know what to do? Although you never received any formal instruction in how to interact with the self-service technology, you were likely able to accomplish your task (e.g., withdrawing or depositing money) as successfully as an experienced user. However, not so long ago, to accomplish that same task, you needed the direct mediation of a service professional who had been trained how to use the required complex technology. What has changed? In short, the …

Enhancing Science Education Through Engaging Visual Content, David Kavanagh

Theses

In recent years a decline in the number of Irish students choosing to study science, at second level and on into third level, has become potentially harmful to the desired creation of a science-based knowledge economy. A primary contributing factor towards this decline is a lack of interest in the subject within the classroom, as was established by The Task Force on the Physical Sciences in 2002.

The primary aim of this Masters research is to investigate the role of visualisation in making the study of science more accessible and engaging to students to counter this decline. To this end …

An Investigation Into A Community Information Database System In The Northeast Of Thailand: Community Empowerment Through Community Learning Centres, Chumnong Wongchachom

Theses: Doctorates and Masters

Following the economic downturn in the late 1990s the Government of Thailand restructured the economy resulting in rapid economic recovery. The society now needs developments to project it into the Information Age. This study is but one creative response to this need. To initiate the study, an extensively validated Questionnaire was implemented with a snowball sample comprising 500 representative, non-randomised respondents from the four provinces of the Inpeng Community Network (ICN). The purpose of the Questionnaire was to ascertain levels of information needs and local knowledge, and to identify ten local experts from ICN for subsequent In-depth Interviews. Data obtained …
