On Computing Condensed Frequent Pattern Bases, Jian Pei, Guozhu Dong, Wei Zou, Jiawei Han Dec 2002

On Computing Condensed Frequent Pattern Bases, Jian Pei, Guozhu Dong, Wei Zou, Jiawei Han

Kno.e.sis Publications

Frequent pattern mining has been studied extensively. However, the effectiveness and efficiency of this mining is often limited, since the number of frequent patterns generated is often too large. In many applications it is sufficient to generate and examine only frequent patterns with support frequency in close-enough approximation instead of in full precision. Such a compact but close-enough frequent pattern base is called a condensed frequent patterns-base.

In this paper, we propose and examine several alternatives at the design, representation, and implementation of such condensed frequent pattern-bases. A few algorithms for computing such pattern-bases are proposed. Their effectiveness at pattern ...

Many enterprise applications, including those supporting e-commerce take a form of processes, which need to be created from individual Web Services and other software components.


The Internet In India And China, Larry Press, William Foster, Peter Wolcott, William Mchenry Oct 2002

The Internet In India And China, Larry Press, William Foster, Peter Wolcott, William Mchenry

Information Systems and Quantitative Analysis Faculty Publications

This article compares the diffusion of the Internet in China and India. Using a six–dimension framework for characterizing the state of the Internet in a nation, we observe that, while both nations have made significant progress since our last comparison (in 1999), China enjoys a substantial lead over India.

We also examine determinants of Internet diffusion. We find that the Chinese Internet has benefited from economic and trade reform begun in the late 1980s, a strong government commitment to the Internet, complementary human and capital resources, etc. The two nations have very different governments and policies, leading to differing ...

Applying Xml/Xslt Technology: A Case Study, Krishnaprasad Thirunarayan Jul 2002

Applying Xml/Xslt Technology: A Case Study, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Typically, paper-based semi-structured documents are used to communicate technical requirements in the industry. One approach to improving the efficiency and flexibility of searching and manipulating these documents is to obtain them in electronic form, and then make explicit the technical content in a form amenable to pattern matching and symbol manipulation. This paper explores the role of XML Technology for these purposes: the use of XML language to make explicit the content of a document in a standard fashion, and the use of XSLT to manipulate the content and mediate between applications that need this content. In order to recognize ...


Implementing Qos Management For Workflow Systems, Jorge Cardoso, Amit P. Sheth, Krzysztof J. Kochut Jul 2002

Implementing Qos Management For Workflow Systems, Jorge Cardoso, Amit P. Sheth, Krzysztof J. Kochut

Kno.e.sis Publications

Workflow management systems (WfMSs) have been used to support various types of business processes. As organizations adopt new working models, such as e-commerce, new challenges arise for workflow systems. One such challenge is that of quality of service (QoS) management. QoS management includes mechanisms that specify, compute, monitor, and control the quality of service of the products or services to be delivered. A good management of QoS directly impacts the success of organizations participating in e-commerce activities by better fulfilling customer expectations and achieving customer satisfaction. In this paper we present an implementation of a comprehensive QoS model for workflows ...


Semi-Automatic Content Extraction From Specifications, Krishnaprasad Thirunarayan, Aaron Berkovich, Dan Z. Sokol Jun 2002

Semi-Automatic Content Extraction From Specifications, Krishnaprasad Thirunarayan, Aaron Berkovich, Dan Z. Sokol

Kno.e.sis Publications

Specifications are critical to companies involved in complex manufacturing. The constant reading, reviewing, and analysis of materials and process specifications is extremely labor-intensive, quality impacting, and time-consuming. A conceptual design for a tool that provides computer-assistance in the interpretation of specification requirements has been created and a strategy for semantic-markup, which is the overlaying of abstract syntax (“the essence”) on the text, has been developed. The solution is based on the techniques for Information Extraction and the XML technology, and it captures the specification content within a semantic ontology. The working prototype of the tool being built will serve as ...

Towards Peer-To-Peer Semantic Web: A Distributed Environment For Sharing Semantic Knowledge On The Web, Madhan Arumugam, Amit P. Sheth, I. Budak Arpinar

Kno.e.sis Publications

The real value of Semantic Web vision can be demonstrated if people and applications can create and discover new and interesting knowledge and share this knowledge in a transparent manner similar to the way data is exchanged today. Therefore, we believe that Semantic Web will consist of a distributed environment of shared and interoperable ontologies, which have emerged as common formalisms for knowledge representation. The users will need to discover new ontologies, which are not known to them before and use them to either annotate the content or to formulate their information requests. This requires an environment that supports creating ...


Modeling Quality Of Service For Workflows And Web Service Processes, Jorge Cardoso, John A. Miller, Amit P. Sheth, Jonathan Arnold May 2002

Modeling Quality Of Service For Workflows And Web Service Processes, Jorge Cardoso, John A. Miller, Amit P. Sheth, Jonathan Arnold

Kno.e.sis Publications

Workflow management systems (WfMSs) have been used to support various types of business processes for more than a decade now. In workflows for e-commerce and Web-services applications, suppliers and customers define a binding agreement or contract between the two parties, specifying Quality of Service (QoS) items such as products or services to be delivered, deadlines, quality of products, and cost of services. The management of QoS metrics directly impacts the success of organizations participating in e-commerce. Therefore, when services or products are created or managed using workflows, the underlying workflow system must accept the specifications and be able to estimate ...

The sample book described herein displays the wound glass beads produced during the third quarter of the 19th century by an acclaimed Venetian firm, that of the Giacomuzzi brothers. The book vividly shows what sorts of beads were being marketed by a single firm at this time, and provides much useful information concerning bead sizing systems. Although not marked with the producers name, the folders that accompany the book are of like date and at least one is likely a product of the Giacomuzzis.


Late Neolithic Amber Beads And Pendants From The Lake Lubāns Wetlands, Latvia, Ilze Biruta Loze Jan 2002

Late Neolithic Amber Beads And Pendants From The Lake Lubāns Wetlands, Latvia, Ilze Biruta Loze

BEADS: Journal of the Society of Bead Researchers

In Late Neolithic Europe, amber beads and pendants were initially mainly made in the coastal zone of the Baltic Sea, due to the presence of amber washed up by the Litorina Sea. There were four principal localized zones of Neolithic amber artifacts in this region: the eastern Baltic, the mouth of the Vistula River, Jutland and Skone, and Fennoscandinavia. The British Isles are regarded as a fifth zone. As the popular-scientific literature has so far provided scant information on the amber-working zone of the eastern Baltic, this article summarizes the findings revealed by extensive archaeological research, particularly during the past ...

In Memoriam: Peter Francis, Jr., 1945-2002, Karlis Karklins Jan 2002

In Memoriam: Peter Francis, Jr., 1945-2002, Karlis Karklins

BEADS: Journal of the Society of Bead Researchers

The bead research community lost a principal member when Peter Francis, Jr., director of the Center for Bead Research in Lake Placid, New York, died December 8, 2002, while on a research trip to Ghana, West Africa. Pete was widely known and respected, and was responsible for significantly increasing people's awareness—on a worldwide scale—of beads and their place in human culture through his many publications, lectures, workshops, symposia, and internet website. He leaves a void that will be very hard, if not impossible, to fill.


Beadwork Of Hungary And Transylvania, Robin Atkins Jan 2002

Beadwork Of Hungary And Transylvania, Robin Atkins

BEADS: Journal of the Society of Bead Researchers

Beading is a cultural necessity in some rural villages of Hungary and Transylvania, where peasants have used embroidery and beads to lavishly embellish their costumes for hundreds of years. Remaining little changed over several centuries and almost oblivious to beads and beadwork in the rest of the world, the peasants of these villages have slowly evolved their own style of beadwork from thread embroidery and other embellishing methods. Based on field research, this article explores the cultural traditions, rich designs, and techniques of beadwork in four Hungarian villages—three in Transylvania (Romania) and one in southern Hungary.
