Beyond Sawsdl - A Game Plan For Broader Adoption Of Semantic Web Services, Amit P. Sheth Jan 2007

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 Jan 2007

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.

Visual Search Performance In A Dynamic Environment With 3d Auditory Cues, John Paul Mcintire Jan 2007

Visual Search Performance In A Dynamic Environment With 3d Auditory Cues, John Paul Mcintire

Browse all Theses and Dissertations

Previous research on aurally-aided visual search has repeatedly shown a significant reduction in response times when displaying 3D auditory cues. However, the vast majority of this research has only examined searches for static (non-moving) targets in static visual environments. In the present study, visual search performance in both static and dynamic (moving) visual environments is examined with and without virtual 3D auditory cues. In both static and dynamic environments, and for all observers, visual search times were significantly reduced when auditory spatial cues were displayed. Auditory cues provided the largest benefits when the target initially appeared at farther eccentricities and …

Sa-Rest: Semantically Interoperable And Easier-To-Use Services And Mashups, Amit P. Sheth, Karthik Gomadam, Jonathan Lathem Jan 2007

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 Jan 2007

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.

A Study On How Completion Of High School, Bachelor’S, And Master’S Degrees Affects Earnings - February 2005, Divya Ashok Jan 2007

A Study On How Completion Of High School, Bachelor’S, And Master’S Degrees Affects Earnings - February 2005, Divya Ashok

Masters Culminating Experiences (1993-2011)

This project indicates that individuals who completed a high school degree, a bachelor’s degree or a master’s degree have substantial differences in earnings. Drawing data from the Current Population Survey for February 2005 and employing an Ordinary Least Square regression technique, this paper examines the determinants that significantly influence the logarithmic hourly earnings of an individual who completed a high school degree, a bachelor’s degree or a master’s degree. Overall, this project suggests that level of education, sex, age, gender, union membership, geographical region and race are the relevant factors that play an important role in determination of hourly earnings …

Semantic Matchmaking Of Web Resources With Local Closed-World Reasoning, Stephan Grimm, Pascal Hitzler Jan 2007

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 Jan 2007

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 Jan 2007

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 Jan 2007

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.

Ions-Vip: A Cognitive Model For Navigating The Web Via Screen Readers, Ion Juvina Jan 2007

Ions-Vip: A Cognitive Model For Navigating The Web Via Screen Readers, Ion Juvina

Psychology Faculty Publications

This paper presents a cognitive perspective on the problem of using the Internet via screen readers. An empirical study shows similarities and dissimilarities between using the Internet via screen readers and via the standard graphical screen. In particular, spatial cognition is an important determinant of web task performance even in the absence of any visual cues. Backtracking behavior has a higher cost and impacts performance in a more negative way when using the Internet via screen readers as compared to the standard use. Selective reading can be used as an addition to the existing functionality of screen readers but more …

Discrimination Across The Sectors: A Comparison Of Discrimination Trends In Private And Public Organizations, Megan K. Leasher

Browse all Theses and Dissertations

Differences and similarities between public and private sector organizations have been hypothesized and researched for several decades (Murray, 1975). This study investigated the differences in claims of employment discrimination reported for employees within the private and public sectors. A longitudinal database of statewide discrimination claims was analyzed to determine if differences in employment discrimination patterns or levels exist between the sectors. Theoretical and practical implications are presented in addition to propositions for future research.

Parameters Affecting Mental Workload And The Number Of Simulated Ucavs That Can Be Effectively Supervised, Bryan A. Calkin Jan 2007

Parameters Affecting Mental Workload And The Number Of Simulated Ucavs That Can Be Effectively Supervised, Bryan A. Calkin

Browse all Theses and Dissertations

The present study investigated performance and mental workload when an operator supervises multiple UCAVs. This study focused on the parameters that affect the operator's performance during a simulated UCAV suppression of enemy air defenses (SEAD) mission, which is expected to be the primary function of the UCAV. All three manipulated factors, including the number of vehicles to be supervised, vehicle airspeed, and difficulty level of attacks (targets engaged by either a single vehicle or multiple vehicles), affected both performance and subjective mental workload measures. A performance mental workload redline was defined as the point at which accomplishment scores no longer …

Non-State Actors And Asymmetric Warfare: A New Paradigm For International Relations, Matthew H. Wahlert Jan 2007

Non-State Actors And Asymmetric Warfare: A New Paradigm For International Relations, Matthew H. Wahlert

Browse all Theses and Dissertations

A billiard table metaphorically explains the conduct of states within the international system- sometimes clashing and other times tenuously co-existing. Yet, the international system ultimately remains a construct and pattern for the state actors. Spatially, the dimensions and context of the system fit the needs, requirements, and structure of the states. However, the system is one dimensional and does not account for the realities of the complexities inherent to the post Cold War Era. Currently, the state actor does not maintain an exclusive monopoly in the formation of the playing field. However, non-state actors usurp space and dimensions not defined …

Effect Of Variable Feedback Delay On Visual Target-Acquisition Performance, Julio Christian Mateo Jan 2007

Effect Of Variable Feedback Delay On Visual Target-Acquisition Performance, Julio Christian Mateo

Browse all Theses and Dissertations

Traditionally, private communication channels with stable characteristics have been used in teleoperation situations. However, recently there have been a few attempts at using public communication channels such as the Internet. In spite of their convenience, very little is known about the effect of the variable delays inherent in this type of channel on motor performance. In this thesis, we provide empirical data on the impact of variable feedback delays on a 3D visual target-acquisition task performed in a virtual environment. Target size, distance between targets, mean feedback delay, and feedback-delay variability were manipulated and the number of errors and movement …

The False Promise Of International Financial Institutions In Building Stable Democracies In Third World Countries, Foday Sulimani Jan 2007

The False Promise Of International Financial Institutions In Building Stable Democracies In Third World Countries, Foday Sulimani

Browse all Theses and Dissertations

The available literature on the democratic process in third world countries shows that there is a strong correlation between the strength of a country's economic and social infrastructure and the successful promotion of democratic principles. It is my assumption that democracy can not be established without strong economic and social infrastructures. Furthermore, the current aid programs as operated by international financial institutions (IFIs) like the International Monetary Fund (IMF), the World Bank and the United States Agency for International Development (USAID) give false hope to third world countries that fail to develop sound socioeconomic policies and yet want to establish …

The causal relationship between measures of deliberative democratic practices and quality of citizen participation were examined using selected variables from the International Association for the Evaluation of Education Achievement's (IEA) 1999 Civic Education Study (CivEd). Logit regression for survey data was used to analyze whether a causal relationship existed between two indicators of deliberative democratic practices and a total of four measures of both current and expected student participation using data from three countries, the United States, England, and Australia. One independent variable, the degree to which students believed their teachers encouraged discussion of controversial political or social issues, had …

The Relationship Between Burnout And Engagement: A Confirmatory Factor Analysis, Gene Michael Alarcon Jan 2007

The Relationship Between Burnout And Engagement: A Confirmatory Factor Analysis, Gene Michael Alarcon

Browse all Theses and Dissertations

Researchers have purported that burnout and engagement measure the same three latent constructs, energy, identification, and efficacy at work, but few have actually researched the theory (Maslach & Leiter, 1997; Schaufeli & Bakker, 2004). Burnout has been consistently related to workplace demands such as emotional labor (Brotheridge & Grandey, 2002; Brotheridge & Lee, 2002). The current study investigated whether burnout and engagement are comprised of energy, identification, and efficacy in a sample with high demands for emotional labor. A confirmatory factor analysis suggested that burnout and engagement might in fact be separate second order latent constructs comprised of only two …
