Semantic Web Technology In Support Of Bioinformatics For Glycan Expression, Amit P. Sheth, William S. York, Christopher Thomas, Meenakshi Nagarajan, John A. Miller, Krzysztof Kochut, Satya S. Sahoo, Xiaochuan Yi

Kno.e.sis Publications

Due to the complexity of biological systems, interpretation of data obtained by a single experimental approach can often be interpreted only if viewed from a broader context, taking into account the information obtained by many diverse techniques. The vast amount of interpreted experimental data that is now available via the internet opens the possibility of collecting the relevant pieces of information that will enable scientists to form hypotheses based on the integration of this diverse information. However, the sheer volume of data that is available makes it very difficult to select the information necessary to make a coherent model of …

Logic Programs, Iterated Function Systems, And Recurrent Radial Basis Function Networks, Sebastian Bader, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Graphs of the single-step operator for first-order logic programs—displayed in the real plane—exhibit self-similar structures known from topological dynamics, i.e., they appear to be fractals, or more precisely, attractors of iterated function systems. We show that this observation can be made mathematically precise. In particular, we give conditions which ensure that those graphs coincide with attractors of suitably chosen iterated function systems, and conditions which allow the approximation of such graphs by iterated function systems or by fractal interpolation. Since iterated function systems can easily be encoded using recurrent radial basis function networks, we eventually obtain connectionist systems which …

Enhancing Web Services Description And Discovery To Facilitate Composition, Preeda Rajasekaran, John A. Miller, Kunal Verma, Amit P. Sheth

Kno.e.sis Publications

Web services are in the midst of making the transition from being a promising technology to being widely used in the industry. However, most efforts to use Web services have been manual, thus slowing down the ever changing and dynamic businesses of today. In this paper, we contend that more expressive descriptions of Web services will lead to greater automation and thus provide more agility to businesses. We present the METEOR-S front-end tools for source code annotation and semantic Web service description generation. We also present WSDL-S, a language created for incorporating semantic descriptions in the industry wide accepted WSDL, …

Learning Mixture Models With The Regularized Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao

Kno.e.sis Publications

This paper presents a new approach to estimating mixture models based on a recent inference principle we have proposed: the latent maximum entropy principle (LME). LME is different from Jaynes' maximum entropy principle, standard maximum likelihood, and maximum a posteriori probability estimation. We demonstrate the LME principle by deriving new algorithms for mixture model estimation, and show how robust new variants of the expectation maximization (EM) algorithm can be developed. We show that a regularized version of LME (RLME), is effective at estimating mixture models. It generally yields better results than plain LME, which in turn is often better than …

Workflow Management Systems And Erp Systems: Differences, Commonalities, And Applications, Jorge Cardoso, Robert P. Bostrom, Amit P. Sheth

Kno.e.sis Publications

Two important classes of information systems, Workflow Management Systems(WfMSs) and Enterprise Resource Planning (ERP) systems, have been used to support e-business process redesign, integration, and management. While both technologies can help with business process automation, data transfer, and information sharing, the technological approach and features of solutions provided by WfMS and ERP are different. Currently, there is a lack of understanding of these two classes of information systems in the industry and academia, thus hindering their effective applications. In this paper, we present a comprehensive comparison between these two classes of systems. We discuss how the two types of systems …

Discovery Of Web Services In A Federated Registry Environment, Kaarthik Sivashanmugam, Kunal Verma, Amit P. Sheth

Kno.e.sis Publications

The potential of a large scale growth of private and semi-private registries is creating the need for an infrastructure which can support discovery and publication over a group of autonomous registries. Recent versions of UDDI have made changes to accommodate interactions between distributed registries. In this paper, we discuss METEOR-S Web service Discovery Infrastructure, which provides an ontology-based infrastructure to access a group of registries that are divided based on business domains and grouped into federations. We also discuss how Web service discovery is carried out within a federation.

Sweto: Large-Scale Semantic Web Test-Bed, Boanerges Aleman-Meza, Chris Halaschek, Amit P. Sheth, I. Budak Arpinar, Gowtham Sannapareddy

Kno.e.sis Publications

The emergent Semantic Web community needs a common infrastructure for testing the scalability and quality of new techniques and software which use machine processable data. Since ontologies are a centerpiece of most approaches, we believe that for an accurate evaluation of tools for quality, scalability and performance, the research community needs a freely available ontology with a large description base. If the use of tools is to be for advanced semantic applications, such as those in business intelligence and national security, then instances in the knowledge base should be highly interconnected. Thus, we propose and describe a Semantic WEb Technology …

Indexing Genomic Databases, Gina Cooper, Michael L. Raymer, Travis E. Doom, Dan E. Krane, Natsuhiko Futamura

Kno.e.sis Publications

Current biological sequence comparison tools utilize full database searches to find approximate matches between a database and a query. A new approach to sequence comparisons can be performed by indexing the database using a novel indexing scheme. An indexed scheme can immediately eliminate highly mismatched sequences thereby improving performance and accuracy. iBlast is proposed as an indexed version of BLAST. In its initial implementation, iBlast uses a sequence-based index to catalog genomic databases in an NCR Teradata RDBMS. Several types of indexes and querying methods are explored to determine the most efficient solution utilizing the parallel nature of the Teradata …

Sempl: A Semantic Portal, Matthew Perry, Eric Stiles

Kno.e.sis Publications

Semantic Web technology is intended for the retrieval, collection, and analysis of meaningful data with significant automation afforded by machine understandability of data [1]. As one illustration of semantic web technology in action, we present SEMPL, a semantic web portal for the Large Scale Distributed Information Systems lab (LSDIS) at the University of Georgia. SEMPL, which is powered by a state of the art commercial system, Semagix Freedom [7], uses an ontology-driven approach to provide semantic browsing, linking, and contextual querying of content within the portal. By using the ontology based information integration technique, SEMPL can specify the context of …

Meteor-S Web Service Annotation Framework, Abhijit A. Patil, Swapna A. Oundhakar, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

The World Wide Web is emerging not only as an infrastructure for data, but also for a broader variety of resources that are increasingly being made available as Web services. Relevant current standards like UDDI, WSDL, and SOAP are in their fledgling years and form the basis of making Web services a workable and broadly adopted technology. However, realizing the fuller scope of the promise of Web services and associated service oriented architecture will requite further technological advances in the areas of service interoperation, service discovery, service composition, and process orchestration. Semantics, especially as supported by the use of ontologies, …

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

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 or Web processes for e-commerce and Web service 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 or Web processes, the underlying workflow engine must accept …

Cost Effectiveness Of Treating The Metabolic Syndrome In The Uninsured In Montgomery County, Deepa Bangalore

Masters Culminating Experiences (1993-2011)

Treating the uninsured in cases of cardiovascular emergencies has demonstrated to be a large expense to the health care system, primarily borne by the society as they contribute to taxes/levies that support local hospitals for indigent care. Interventions to reduce the cardiovascular risk factors among the uninsured are expensive but have proven to be an effective alternative to the present situation, which is to treat them only in cases of emergencies. The metabolic syndrome (MS) poses a threat particularly to the uninsured population because of its asymptomatic nature. Detection and treatment of MS at its onset provides substantial clinical benefit …

A Comparative Evaluation Of The Cost Effectiveness Of Treating The Metabolic Syndrome In African Americans And The General Population, Joseph T. Tasosa

Masters Culminating Experiences (1993-2011)

The Metabolic Syndrome poses an important public health threat to the U.S. health care delivery system. Disparate access to quality health care makes African Americans (blacks) especially susceptible to the adverse effects of MS. Although direct evidence suggests that early treatment of MS risk factors saves lives, no study to date has compared the cost effectiveness of such measures in blacks and the general population. Interventions that promote early treatment of MS risk factors may improve public health but could also lead to excess costs that are ultimately borne by society. The objective of this study was to assess the …

Cost Benefit Analysis Of An Automated Labeling System For Green Tokai Co., Ltd., Glenn Charles Wintrich

Masters Culminating Experiences (1993-2011)

This project was conducted in order to analyze the causes of domestic trouble tickets (DTRs) at Green Tokai Co., Ltd., as well as provide recommendations on how to reduce them. DTRs cost Green Tokai $518,000 annually.

At the onset of this project it became clear that one of the major contributors to DTRs was the labeling process that was in place. Green Tokai was shipping incorrectly labeled parts to customers. This problem became the primary focus of the project, and several recommendations were made in order to reduce the DTRs due to labeling issues.

Many of the labeling issues could …

Momentum Strategies Versus Directional Momentum Strategies: A Comparative Study With Stocks, Zi Ning

Masters Culminating Experiences (1993-2011)

In replicating the study by Akhbari and Gressis (2002) in mutual funds, this paper compares the profitability of traditional momentum strategy with the directional momentum strategies in stock markets. Not only the past quarterly return but also the patterns of monthly returns within a quarter are considered. The evidence shows that the raw return findings are similar to the findings in mutual fund study. However, the risk- adjusted returns are not consistent with the raw returns and statistically insignificant, very probably, due to the extremely small sample size.
