Maintaining Transitive Closure Of Graphs In Sql, Guozhu Dong, Leonid Libkin, Jianwen Su, Limsoon Wong

Kno.e.sis Publications

It is common knowledge that relational calculus and even SQL are not expressive enough to express recursive queries such as the transitive closure. In a real database system, one can overcome this problem by storing a graph together with its transitive closure and maintaining the latter whenever updates to the former occur. This leads to the concept of an incremental evaluation system, or IES.

Much is already known about the theory of IES but very little has been translated into practice. The purpose of this paper is to fill in this gap by providing a gentle introduction to and …

Infoharness: Managing Distributed, Heterogeneous Information, Kshitij Shah, Amit P. Sheth

Kno.e.sis Publications

Today, important information is scattered in so many places, formats, and media, that getting the right information at the right time and place is an extremely difficult task. Developing a single software product, for example, includes the creation of documents ranging from the requirements specification and project schedules to marketing presentations, multimedia tutorials, and more. Each document may be created by a different person using a different tool, and each may be stored in a different place. InfoHarness is an information integration system, platform, and tool set that addresses these problems, managing huge amounts of heterogeneous information in a distributed …

Integrating Web-Based Training Into Communication Scholarship Of Computer-Mediated Communication, Brian P. Johanpeter

Masters Theses

As interest and use of the Internet through the World Wide Web increases, it becomes necessary for the Communication Discipline to reexamine its approach to studying computer-mediated communication. A meta-analysis of the discipline's research in this area provides insight into the scholarly history of this subject. Included in this analysis is an examination of the discipline's research in computer-based instruction, placed as a subcategory under computer-mediated communication. This study reveals a gaping hole in the communication scholarship of computer-mediated communication and offers suggestions as to how research of Web-based training might fill this gap. Additional discussion also reveals how research …

The Threat Of Long-Arm Jurisdiction To Electronic Commerce, Robert J. Aalberts, Anthony M. Townsend, Michael E. Whitman

Faculty Articles

Unfortunately for those whose businesses rely on the Internet, an increasing amount of legal conflict is also arising in reaction to this new business medium. As attorneys and the courts attempt to sort out the Internet’s legal status quo, both are considering such pressing substantive issues as electronic contracts, privacy, trademark, copyright, defamation, computer crimes, censorship, and taxation. It is imperative that information system professionals become aware of how evolving Internet law will affect the medium they are charged with administrating. An informed IS community is also much more capable of mounting legal and political challenges to law that might …

Business Faculty Articles and Research

Interest in the role of video supers-superimposed video presentations of verbal information-has grouwn among consumers, advertisers, the television networks, and public policymakers, as supers have become prevalent in television commercials. The authors empirically address the communications efficacy of video supers in a sample of 200 different commercials that contain video supers Drawing on a theory of modality effects, the authors examine the comprehensive of video supers relative to commercial content. The authors develop hypotheses and analyze structural determinants of video super comprehension, such as presence of a voice-over, rate of presentation, and presentation size. The findings are supportive of the …

Logical Information Modeling Of Web-Accessible Heterogeneous Digital Assets, Kshitij Shah, Amit P. Sheth

Kno.e.sis Publications

This paper introduces the MREF framework for representing and correlating information at a higher semantic level than is possible with Web-based information systems today. The role that metadata plays in this framework is described, together with a metadata based infrastructure to support our media independent information correlation paradigm. To keep it consistent with evolving standards, broader acceptance and ease of implementation, MREF abstraction is structured on top of RDF and XML. Its central role in the context of the InfoQuilt system, for exploiting heterogeneous digital media using a federated and scalable architecture, is briefly described.

Zebra Image Access System, Srilekha Mudumbai, Kshitij Shah, Amit P. Sheth, Krishnan Parasuraman, Clemens Bertram

Kno.e.sis Publications

The ZEBRA system, which is part of the VisualHarness platform for managing heterogeneous data, supports three types of access to distributed image repositories: keyword based, attribute based, and image content based. A user can assign different weights (relative importance) to each of the three types, and within the last type of access, to each of the image properties. The image based access component (IBAC) supports access based on computable image properties such as those based on spatial domain, frequency domain or statistical and structural analysis. However, it uses a novel black box approach of utilizing a Visual Information Retrieval (VIR) …

Strictly Level-Decreasing Logic Programs, Pascal Hitzler, Anthony K. Seda

Computer Science and Engineering Faculty Publications

We study strictly level-decreasing logic programs (sld-programs) as defined earlier by the present authors. It will be seen that sld-programs, unlike most other classes of logic programs, have both a highly intuitive declarative semantics, given as a unique supported model, and are computationally adequate in the sense that every partial recursive function can be represented by some sld-program P. Allowing for a safe use of cuts, an interpreter based on SLDNF-resolution, as implemented for example in standard Prolog systems, is shown to be sound and complete with respect to this class of programs. Furthermore, we study connections between topological …

Interestingness Of Discovered Association Rules In Terms Of Neighborhood-Based Unexpectedness, Guozhu Dong, Jinyan Li

Kno.e.sis Publications

One of the central problems in knowledge discovery is the development of good measures of interestingness of discovered patterns. With such measures, a user needs to manually examine only the more interesting rules, instead of each of a large number of mined rules. Previous proposals of such measures include rule templates, minimal rule cover, actionability, and unexpectedness in the statistical sense or against user beliefs.

In this paper we will introduce neighborhood-based interestingness by considering unexpectedness in terms of neighborhood-based parameters. We first present some novel notions of distance between rules and of neighborhood of rules. The neighborhood-based interestingness of …

Health Care Marketing And The Internet, C. David Shepherd, Daniel Fell

Faculty Articles

This article presents research on the growing number of health care providers using the Internet as a health care marketing tool in the U.S. The author notes that the Internet is changing the way consumers seek healthcare related information as well as the way it can be provided to them. The results of the study suggest that consumers will increasingly rely on sources like the Internet for information, that health information will be a commodity on the Internet, that the Internet will help build relationships between providers and consumers and that marketers will be expected to develop and manage Internet-related …

From Contemporary Workflow Process Automation To Adaptive And Dynamic Work Activity Coordination And Collaboration, Amit P. Sheth

Kno.e.sis Publications

The article outlines a research agenda for researchers in the area of workflow. We believe that today's workflow systems should evolve to what is termed as work coordination and collaboration systems (WCCSs). A WCCS will: (a) adapt to various changes in the organization (including its interactions with external organizations) and the organizational processes by being able to change the process definitions as well as change the processes and component activities while they are being enacted or executed; and (b) support a unified framework for managing coordination, collaboration, and information based decision making activities that naturally occur as part of organizational …

A Vhdl-93 Hardware Description Browser, Laura C. Debrock, Krishnaprasad Thirunarayan

Kno.e.sis Publications

This paper describes the design and implementation of the VHDL-93 Hardware Description Browser, which is a tool for the intelligent retrieval of information from VHDL designs. The Browser consists of two UNIX processes: a TCL/TK Graphical User Interface and a Prolog search engine. The GUI elicits queries from the user and submits them to the Prolog search engine via a two-way communication pipe. The search engine satisfies queries by traversing a forest of parse trees corresponding to the associated VHDL designs. The results are then sent to the GUI for posting.

Two public-domain tools were used to implement the Browser: …

These applications concern(a) accessing a legacy scientific database, (b) automating a workflow involving legacy systems, (c) cleaning data, and (d) retrieving semantically appropriate information from structured databases in response to text queries. These applications support scientific decision support, business process management, data integrity enhancement, and analytical decision support, respectively. They demonstrate Carnot‘s capabilities for (a) heterogeneous query processing, …

Characterizing A Portable Subset Of Behavioral Vhdl-93, Krishnaprasad Thirunarayan, Robert Ewing

Kno.e.sis Publications

Goossens defined a structural operational semantics for a subset of VHDL-87 and proved that the parallelism present in VHDL is benign. We extend this work to include VHDL-93 features such as shared variables and postponed processes that change the underlying semantic model. In the presence of shared variables, nondeterministic execution of VHDL-93 processes destroys the unique meaning property. We identify and characterize a class of portable VHDL-93 descriptions for which unique meaning property can be salvaged. Our specification can serve as a correctness criteria for a VHDL-93 simulator.

Editors Notes: Issue 6, Loretta L. Lange

SWITCH

The editor states that The Web is having an explosive growth with artists seeking to explore this new territory. Through various discussions it has been determined that there are many sides to this subject that warrants investigation in two separate issues. For this issue, there is more of an explorative focus, and for the next there is analysis and critique. There is web art that promotes, as Susan Gablik states, “intensification of the aesthetic process in a void.” Others seek to include viewers as participants. Web-specific art brings up many questions for art, recontextualizing what we know in regards to …
