Dissertations and Theses

Recent research has focused on the cooperation of web server and database server software in the deployment of data-intensive web sites. That work has focused either on storing data in a database that can be used to generate the contents of a web site, or on providing interfaces and gateways to enable queries to be invoked from web pages and executed at external database servers.

This thesis describes the implementation of a prototype of the Data Web system that is being implemented at Portland State University. With Data Web, a user can embed in a web page virtual tables that …

Local Properties Of Query Languages, Guozhu Dong, Leonid Libkin, Limsoon Wong

Kno.e.sis Publications

In this paper we study the expressiveness of local queries. By locality we mean — informally — that in order to check if a tuple belongs to the result of a query, one only has to look at a certain predetermined portion of the input. Examples include all relational calculus queries. We start by proving a general result describing outputs of local queries. This result leads to many easy inexpressibility proofs for local queries. We then consider a closely related property, namely, the bounded degree property. It describes the outputs of local queries on structures that locally look “simple.” Every …

Predictive Adaptive Resonance Theory And Knowledge Discovery In Databases, Ah-Hwee Tan, Hui-Shin Vivien Soon

Research Collection School Of Computing and Information Systems

This paper investigates the scalability of predictive Adaptive Resonance Theory (ART) networks for knowledge discovery in very large databases. Although predictive ART performs fast and incremental learning, the number of recognition categories or rules that it creates during learning may become substantially large and cause the learning speed to slow down. To tackle this problem, we introduce an on-line algorithm for evaluating and pruning categories during learning. Benchmark experiments on a large scale data set show that on-line pruning has been effective in reducing the number of the recognition categories and the time for convergence. Interestingly, the pruned networks also …

Load Sharing In Distributed Multimedia-On-Demand Systems, Y. C. Tay, Hwee Hwa Pang

Research Collection School Of Computing and Information Systems

Service providers have begun to offer multimedia-on-demand services to residential estates by installing isolated, small-scale multimedia servers at individual estates. Such an arrangement allows the service providers to operate without relying on a highspeed, large-capacity metropolitan area network, which is still not available in many countries. Unfortunately, installing isolated servers can incur very high server costs, as each server requires spare bandwidth to cope with fluctuations in user demand. The authors explore the feasibility of linking up several small multimedia servers to a (limited-capacity) network, and allowing servers with idle retrieval bandwidth to help out servers that are temporarily overloaded; …

Enhancing A Virtual Distributed Library User Interface Via Server-Side User Profile Caching, Jason T. Ward

Theses and Dissertations

Various Department of Defense (DoD) agencies archive terabytes of intelligence imagery and electrooptical signature data. The Air Force Research Laboratory, Sensors Directorate (AFRL/SN), is tasked with creating and managing a virtual distributed library that facilitates secure, detailed queries across these distributed holdings using the internally developed Advanced Query Tool (AQT). In this research, a methodology is proposed to utilize user profiling techniques to augment a digital library. As part of this methodology, product-oriented usability analysis metrics are introduced that quantitatively verify the usability of an interface. The methodology is applied to the AFRL/SN's Virtual Distributed Laboratory AQT and subsequently analyzed …

A Framework For Acquiring Domain Semantics And Knowledge For Database Integration, Roger Hsiang-Li Chiang, Ee Peng Lim, Veda C. Storey

Research Collection School Of Computing and Information Systems

Database integration research has traditionally focused on understanding integration issues from the schema and instance perspectives. As a result, database integration approaches tend to rely on a direct comparison of schema and instance elements. However, when the integration of heterogeneous databases is performed without considering the domain semantics and knowledge of local databases such as context information and requirement specifications, an incorrect integrated database may be produced. In this research, a framework for carrying out database integration tasks using the above knowledge is proposed. The framework provides a thorough foundation to: 1. analyze database integration issues from a broad scope, …

Cataloging Expert Systems: Optimism And Frustrated Reality, William Olmstadt

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

There is little question that computers have profoundly changed how information professionals work. The process of cataloging and classifying library materials was one of the first activities transformed by information technology. The introduction of the MARC format in the 1960s and the creation of national bibliographic utilities in the 1970s had a lasting impact on cataloging. In the 1980s, the affordability of microcomputers made the computer accessible for cataloging, even to small libraries. This trend toward automating library processes with computers parallels a broader societal interest in the use of computers to organize and store information. Following World War II, …

Collaborative Software Agents Support For The Texpros Document Management System, Jrtian Lin

Dissertations

This dissertation investigates the use of active rules that are embedded in markup documents. Active rules are used in a markup representation by integrating Collaborative Software Agents with TEXPROS (abbreviation for TEXt PROcessing System) [Liu and Ng 1996] to create a powerful distributed document management system. Such markup documents with embedded active rules are called Active Documents. For fast retrieval purposes, when we need to generate a customized Internet folder organization, we first define the Folder Organization Query Language (FO-QL) to solve data categorization problems. FO-QL defines the folder organization query process that automatically retrieves links of documents deposited into …

The Space Of Jumping Emerging Patterns And Its Incremental Maintenance, Jinyan Li, Kotagiri Ramamohanarao, Guozhu Dong

Kno.e.sis Publications

The concept of jumping emerging patterns (JEPs) has been proposed to describe those discriminating features which only occur in the positive training instances but do not occur in the negative class at all; JEPs have been used to construct classifiers which generally provide better accuracy than the state-of-the-art classifiers such as C4.5. The algorithms for maintaining the space of jumping emerging patterns (JEP space) are presented in this paper. We prove that JEP spaces satisfy the property of convexity. Therefore JEP spaces can be concisely represented by two bounds: consisting respectively of the most general elements and the most specific …

Assurance Services For Business-To- Business Electronic Commerce: A Framework And Implications, Deepak Khazanchi, Steve G. Sutton

Information Systems and Quantitative Analysis Faculty Publications

The electronic commerce assurance market has been estimated to be potentially worth $11 billion. To date the focus of assurance services has largely been on web commerce (and therefore business to consumer) related services, leaving the business-to-business (B2B or B-to-B) electronic commerce market relatively untapped. Yet, with Electronic Data Interchange (EDI) being mandated by large companies and government agencies, small- to medium-sized firms have struggled to acquire and implement this technology with little understanding of this new age of electronic commerce. As the ubiquitous Internet allows more firms to become EDI-capable, there is an imminent need for having some independent …

Inclusive Production Of Π0, Η, Η′ (958), Kg0s And Λ In Two- And Three-Jet Events From Hadronic Z Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The production rates and the inclusive cross sections of the isovector meson π0π0, the isoscalar mesons ηη and η′(958)η′(958), the strange meson K0SKS0 and the ΛΛ baryon have been measured as functions of scaled energy in hadronic events, two-jet events and each jet of three-jet events from hadronic Z decays and compared to Monte Carlo models. The analysis is based on 3.7 million hadronic events collected with the ALEPH detector at LEP at a centre-of-mass energy of s√=91.2s=91.2 GeV. The JETSET modelling of the gluon fragmentation into isoscalar mesons is found to be in agreement with the experimental results. HERWIG …

Study Of Charm Production In Z Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The production rates of D∗±D∗±, D∗±sDs∗±, D±D±, D0/D¯0D0/D¯0, D±sDs±, and Λ+c/Λ¯−cΛc+/Λ¯c− in Z→cc¯Z→cc¯ decays are measured using the LEP I data sample recorded by the ALEPH detector. The fractional energy spectrum of the D∗±D∗± is well described as the sum of three contributions: charm hadronisation, b hadron decays and gluon splitting into a pair of heavy quarks. The probability for a c quark to hadronise into a D∗+D∗+ is found to be f(c→D∗+)=0.233±0.010(stat.)±0.011(syst.)f(c→D∗+)=0.233±0.010(stat.)±0.011(syst.). The average fraction of the beam energy carried by D∗±D∗± mesons in Z→cc¯Z→cc¯ events is measured to be ⟨XE(D∗±)⟩cc¯=0.4878±0.0046(stat.)±0.0061(syst.).⟨XE(D∗±)⟩cc¯=0.4878±0.0046(stat.)±0.0061(syst.).

Systems Integration: A Tool For Project Monitoring In The Public Sector, Baharum Noriati

Student Works (2000-2009)

Many computerized systems today operate within organizational boundaries. In the Malaysian public sector, early systems were developed to solve organizational business functions. In the course of developing application systems to resolve specific needs, these organizations hardly look beyond the boundaries of their business domain. This phenomenon led to the existence of islands of information systems within the government sector. In this study, the researcher proposed to look into the issues of systems integration (SI) within the public sector, in general and subsequently proceed to an area where SI is deemed to be appropriate. Project monitoring for the government in Malaysia …

Imprecise Answers In Distributed Environments: Estimation Of Information Loss For Multi-Ontology Based Query Processing, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a higher level of abstraction. It is not practical to have a single domain ontology to describe the vast amounts of data on the Web. In fact, we expect multiple ontologies to be used as different world views and present an approach to "browse" ontologies as a paradigm for information access. …

Optimization Techniques For Data Intensive Decision Flows, Richard Hull, Francois Llirbat, Bharat Kumar, Gang Zhou, Guozhu Dong, Jianwen Su

Kno.e.sis Publications

For an enterprise to take advantage of the opportunities afforded by electronic commerce it must be able to make decisions about business transactions in near-real-time. In the coming era of segment-of-one marketing, these decisions will be quite intricate, so that customer treatments can be highly personalized, reflecting customer preferences, the customer's history with the enterprise, and targeted business objectives. This paper describes a paradigm called “decision flows” for specifying a form of incremental decision-making that can combine diverse business factors in near-real-time.

This paper introduces and empirically analyzes a variety of optimization strategies for decision flows that are “data-intensive”, i.e. …
