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.

Extending Bpel For Interoperable Pervasive Computing, Gregory Hackmann, Christopher Gill, Christopher Gill, Gruia-Catalin Roman

All Computer Science and Engineering Research

The widespread deployment of mobile devices like PDAs and mobile phones has created a vast computation and communication platform for pervasive computing applications. However, these devices feature an array of incompatible hardware and software architectures, discouraging ad-hoc interactions among devices. The Business Process Execution Language (BPEL) allows users in wired computing settings to model applications of significant complexity, leveraging Web standards to guarantee interoperability. However, BPEL's inflexible communication model effectively prohibits its deployment on the kinds of dynamic wireless networks used by most pervasive computing devices. This paper presents extensions to BPEL that address these restrictions, transforming BPEL into a …

Link Layer Support For Unified Radio Power Management In Wireless Sensor Networks, Master's Thesis, May 2007, Kevin Klues

All Computer Science and Engineering Research

Radio power management is of paramount concern in wireless sensor networks that must achieve long lifetimes on scarce amounts of energy. While a multitude of power management protocols have been proposed in the past, the lack of system support for flexibly integrating them with a diverse set of applications and network platforms has made them difficult to use. Instead of proposing yet another power management protocol, this thesis focuses on providing link layer support towards realizing a Unified Power Management Architecture (UPMA) for flexible radio power management in wireless sensor networks. In contrast to the monolithic approaches adopted by existing …

An Analysis Of It/Is Offshore Outsourcing: Educator Perspectives, Martin H. Bagaya

CCAC Theses and Dissertations

IT/IS Offshore outsourcing is defined as a commercial arrangement of transferring local ITIIS functions, assets, activities, products and services to a foreign contractor therefore removing new employment positions, replacing or displacing U.S. domestic IT/IS workers with those from other countries for financial or competitive advantage of the outsourcing client. This process of offshore outsourcing to overseas locations was perceived to have consequences on IT/IS student enrolment at U.S. universities.

The objective of this study was to identify administrators' responses to reduced IT/IS student enrolments. The majority of ITIIS college administrators have concerns about offshore outsourcing, and is perceived to reduce …

Electronic Performance Support For E-Learning Analysis And Design, Thomas W. Jury

CCAC Theses and Dissertations

Corporate instructional designers often follow an instructional systems design (ISD) process to plan, create, and implement training programs. Increased demand for elearning as a replacement or addition to classroom training means that, in the current corporate environment, instructional designers are called upon to produce a wide variety of instructional formats and have to make more decisions during the ISD process.

E-learning is evolving into a total performance improvement solution rather than simply as a means to delivering distance training and consequently, in an effort to achieve business goals, many corporations are turning to it as a cost effective way to …

Measuring The Effect Of E-Learning On Job Performance, Heidi Kramer

CCAC Theses and Dissertations

E-learning is becoming a leading delivery method in workplace-learning settings across organizations of various sectors and of varying sizes. The ultimate goal is to drive business results. Managers need to provide evidence of a positive impact on corporate strategy and investment objectives. If the business goal cannot be identified, there should be a query on why it is there in the first place. Transfer of the knowledge learned in the training session to the work situation is not built into most skills training delivery, especially those provided through e-learning. The outcomes and the effects of training on job performance are …

Painting The Voice: Weblogs And Writing Instruction In The High School Classroom, Marilyn V. Olander

CCAC Theses and Dissertations

Writing is a complex cognitive skill, a technology for capturing speech whose forms and conventions began in the dawn of civilization and were in place and stable by the Middle Ages. Writing and reading are the foundation of literacy, fundamental to success in school and in the adult world. No comprehensive theory of composition guides the teaching of writing, although historically two approaches have been favored: writing as a skill acquired through the memorization and recognition of principles of grammar and usage, and more recently, writing as a process of recursive strategies of pi arming, drafting, revising, editing, and publishing. …

Measuring Factors That Influence The Success Of E-Government Initiatives, Ronnie Park

CCAC Theses and Dissertations

The success of e-government initiatives is contingent upon its citizens ' willingness to use the services. Citizens are more likely to use e-government services if they believe that they get better value than from the conventional government services. Understanding how citizens value e-government services is critical to the success of these initiatives. This study utilizes two concepts from the field of decision analysis. These are mean-ends chains and value-focused thinking. The research that follows describes the development of a model to identify factors that influence value judgments of citizens.

Based on the data of 21 0 responses from e-government service …

Free online multimedia hosting services are popularly cherished, such as “youtube.com” and “yahoo video”, and with the increasing affordability of digital camera, hundreds, or maybe thousands, of home-made videos and music audio are created daily and published online. Low-cost digital recorders such as webcams also help promote the use …

Value-At-Risk In It Services Contracts, Robert J. Kauffman, Ryan Sougstad

Research Collection School Of Computing and Information Systems

As information systems (IS) and technology solutions become increasingly service-driven, managers are faced with the task of choosing parameters such as service-levels, pricing, and contract duration. Information technology (IT) services vendors manage portfolios of contracts in which parameters, decided at inception, are often subject to future risks. The contract profit maximization decision may adversely affect the risk position of the firm's portfolio of services contracts. We propose a model to inform vendors on setting optimal parameters for IS contracts subject to acceptable levels of risk. The analytic model presented draws from IS economics research and the principles of value-at-risk (VaR) …

Containing Denial-Of-Service Attacks In Broadcast Authentication In Sensor Networks, Ronghua Wang, Wenliang Du, Peng Ning

Electrical Engineering and Computer Science - All Scholarship

Broadcast authentication is an important application in sensor networks. Public Key Cryptography (PKC) is desirable for this application, but due to the resource constraints on sensor nodes, these operations are expensive, which means sensor networks using PKC are susceptible to Denial of Service (DoS) attacks: attackers keep broadcasting bogus messages, which will incur extra costs, thus exhaust the energy of the honest nodes. In addition, the long time to verify each message using PKC increases the response time of the nodes; it is impractical for the nodes to validate each incoming message before forwarding it. In this paper we discuss …

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.

Augmentation In Visual Reality (Avr), Yunjun Zhang

Electronic Theses and Dissertations

Human eyes, as the organs for sensing light and processing visual information, enable us to see the real world. Though invaluable, they give us no way to "edit" the received visual stream or to "switch" to a different channel. The invention of motion pictures and computer technologies in the last century enables us to add an extra layer of modifications between the real world and our eyes. There are two major approaches to modifications that we consider here, offline augmentation and online augmentation. The movie industry has pushed offline augmentation to an extreme level; audiences can experience visual surprises that …

A Grounded Theory Approach To Identifying And Measuring Forensic Data Acquisition Tasks, Gregory H. Carlton

Journal of Digital Forensics, Security and Law

As a relatively new field of study, little empirical research has been conducted pertaining to computer forensics. This lack of empirical research contributes to problems for practitioners and academics alike.

For the community of practitioners, problems arise from the dilemma of applying scientific methods to legal matters based on anecdotal training methods, and the academic community is hampered by a lack of theory in this evolving field. A research study utilizing a multi-method approach to identify and measure tasks practitioners perform during forensic data acquisitions and lay a foundation for academic theory development was conducted in 2006 in conjunction with …

An Exploratory Analysis Of Computer Mediated Communications On Cyberstalking Severity, Stephen D. Barnes, David P. Biros

Journal of Digital Forensics, Security and Law

The interaction between disjunctive interpersonal relationships, those where the parties to the relationship disagree on the goals of the relationship, and the use of computer mediated communications channels is a relatively unexplored domain. Bargh (2002) suggests that CMC channels can amplify the development of interpersonal relationships, and notes that the effect is not constant across communications activities. This proposal suggests a line of research that explores the interaction between computer mediated communications (CMC) and stalking, which is a common form of disjunctive relationships. Field data from cyberstalking cases will be used to look at the effects of CMC channels on …
