Semantic (Web) Technology In Action: Ontology Driven Information Systems For Search, Integration, And Analysis, Amit P. Sheth, Cartic Ramakrishnan Dec 2003

Semantic (Web) Technology In Action: Ontology Driven Information Systems For Search, Integration, And Analysis, Amit P. Sheth, Cartic Ramakrishnan

Kno.e.sis Publications

Semantics is seen as the key ingredient in the next phase of the Web infrastructure as well as the next generation of information systems applications. In this context, we review some of the reservations expressed about the viability of the Semantic Web. We respond to these by identifying a Semantic Technology that supports the key capabilities also needed to realize the Semantic Web vision, namely representing, acquiring and utilizing knowledge. Given that scalability is a key challenge, we briefly review our observations from developing three classes of real world applications and corresponding technology components: search/browsing, integration, and analytics. We distinguish …

Validating And Refining Clusters Via Visual Rendering, Keke Chen, Ling Liu Nov 2003

Validating And Refining Clusters Via Visual Rendering, Keke Chen, Ling Liu

Kno.e.sis Publications

The automatic clustering algorithms are known to work well in dealing with clusters of regular shapes, e.g. compact spherical/elongated shapes, but may incur higher error rates when dealing with arbitrarily shaped clusters. Although some efforts have been devoted to addressing the problem of skewed datasets, the problem of handling clusters with irregular shapes is still in its infancy, especially in terms of dimensionality of the datasets and the precision of the clustering results considered. Not surprisingly, the statistical indices works ineffective in validating clusters of irregular shapes, too. We address the problem of clustering and validating arbitrarily shaped clusters with …


Towards (Semi-) Automatic Generation Of Bio-Medical Ontologies, Vipul Kashyap, Cartic Ramakrishnan, Thomas Rindflesch Nov 2003

Towards (Semi-) Automatic Generation Of Bio-Medical Ontologies, Vipul Kashyap, Cartic Ramakrishnan, Thomas Rindflesch

Kno.e.sis Publications

The design and construction of domain specific ontologies and taxonomies requires allocation of huge resources in terms of cost and time. These efforts are human intensive and we need to explore ways of minimizing human involvement and other resources. In the biomedical domain, we seek to leverage resources such as the UMLS1 Metathesaurus and NLP-based applications such as MetaMap2 in conjunction with statistical clustering techniques, to (partially) automate the process. This is expected to be useful to the team involved in developing MeSH and other biomedical taxonomies to identify gaps in the existing taxonomies, and to be able to quickly …


Semantic E-Workflow Composition, Jorge Cardoso, Amit P. Sheth Nov 2003

Semantic E-Workflow Composition, Jorge Cardoso, Amit P. Sheth

Kno.e.sis Publications

Systems and infrastructures are currently being developed to support Web services. The main idea is to encapsulate an organization's functionality within an appropriate interface and advertise it as Web services. While in some cases Web services may be utilized in an isolated form, it is normal to expect Web services to be integrated as part of workflow processes. The composition of workflow processes that model e-service applications differs from the design of traditional workflows, in terms of the number of tasks (Web services) available to the composition process, in their heterogeneity, and in their autonomy. Therefore, two problems need to …

Paper Use And Recycling In Academic Libraries, Michele Calloway, Darren Callahan Oct 2003

Paper Use And Recycling In Academic Libraries, Michele Calloway, Darren Callahan

E-JASL 1999-2009 (Volumes 1-10)

Conclusions

While it is difficult to predict what the future may hold in regard to paper use and recycling, without a doubt, academic libraries are sites of enormous consumption and they should be proactive in institutional improvements in waste management. A paperless society is unlikely to become a reality for a very long time, if ever, but what can libraries do now to discourage paper waste and encourage recycling? According to the results of this survey, libraries are taking steps to divert recyclables from the garbage. In the future, as people become even more accustomed to working in the electronic …


Digital Reference Evaluation: Assessing The Past To Plan For The Future, J. B. Hill, Cherie Madarash-Hill, Ngoc Pham Thi Bich Oct 2003

Digital Reference Evaluation: Assessing The Past To Plan For The Future, J. B. Hill, Cherie Madarash-Hill, Ngoc Pham Thi Bich

E-JASL 1999-2009 (Volumes 1-10)

Historically, libraries have routinely evaluated their reference services both quantitatively and qualitatively. With the increasing volume of digital reference transactions, there is a need to modify and apply to digital reference, the same evaluation techniques that have been used successfully in the evaluation of traditional reference service. At Southeastern Louisiana University, a recent evaluation of the library's Ask a Librarian digital reference service included an unobtrusive observation of current practice through a detailed examination of archived reference transactions, as well as an assessment of future needs through a survey of users. Through this evaluation, it was possible to assess the …

The process of document delivery will be explained and the amount of work at one institution will be displayed. An examination of Association of Research Libraries (ARL) members will also take place to see who is providing document delivery and if the patron is charged. Lastly, a commentary on the value and service provided and things to consider will be touched on.


Usability Of E-Journals And Preference For The Virtual Periodicals Room: A Survey Of Mathematics Faculty And Graduate Students, Lutishoor Salisbury, Emilio Noguera Oct 2003

Usability Of E-Journals And Preference For The Virtual Periodicals Room: A Survey Of Mathematics Faculty And Graduate Students, Lutishoor Salisbury, Emilio Noguera

E-JASL 1999-2009 (Volumes 1-10)

Introduction

Using several variables, the University of Arkansas Libraries conducted a survey in 2002 to measure the nature and extent of journal use in the Mathematics Reading Room, the Virtual Periodicals Room and Mullins Library.

The aims of this survey were two-fold: firstly, to collect information on the current level of support for electronic-only journals to aid in collection development, and secondly, to ascertain whether a Virtual Periodicals Room is a viable alternative to the physical Reading Room for the Mathematics faculty.

Conclusion

It is obvious from the results of the survey that greater use is being made of the …


Bibliographic Instruction: Two Models Converging In A Common Goal, Stephen J. Shaw Oct 2003

Bibliographic Instruction: Two Models Converging In A Common Goal, Stephen J. Shaw

E-JASL 1999-2009 (Volumes 1-10)

Introduction

This essay will explore research in the undergraduate curriculum by examining the divergent ways research is understood. The debate centers around the ways that the typical student perceives the role of the library in her education at the university. To limit the discussion to the relation between the student and the librarian misses the larger issue at stake. What needs does the average undergraduate have after completion of the B.A., if they have no plans to continue education further? Are research skills necessary only for the graduate student, or is there some truth to the humanistic notion of 'knowledge …

The Local Nature Of Digital Reference, Teresa U. Berry, Margaret M. Casado, Lana Dixon Oct 2003

The Local Nature Of Digital Reference, Teresa U. Berry, Margaret M. Casado, Lana Dixon

The Southeastern Librarian

In response to the extensive availability of digital library resources and the rising number of remote users, many libraries now offer digital reference services through e-mail and chat. The growing use of interactive chat software with its real time interactive capability has prompted librarians to consider collaborative ways in which to offer this service. A concern expressed frequently in informal discussions of such collaborations is how difficult it would be for the staff at one library to answer questions for another, considering that many questions tend to be “local”. Intrigued by the perception of “local,” librarians at the University of …

Continuity Of Semantic Operators In Logic Programming And Their Approximation By Artificial Neural Networks, Pascal Hitzler, Anthony K. Seda Sep 2003

Continuity Of Semantic Operators In Logic Programming And Their Approximation By Artificial Neural Networks, Pascal Hitzler, Anthony K. Seda

Computer Science and Engineering Faculty Publications

One approach to integrating first-order logic programming and neural network systems employs the approximation of semantic operators by feedforward networks. For this purpose, it is necessary to view these semantic operators as continuous functions on the reals. This can be accomplished by endowing the space of all interpretations of a logic program with topologies obtained from suitable embeddings. We will present such topologies which arise naturally out of the theory of logic programming, discuss continuity issues of several well-known semantic operators, and derive some results concerning the approximation of these operators by feedforward neural networks.


Context-Aware Semantic Association Ranking, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Amit P. Sheth Sep 2003

Context-Aware Semantic Association Ranking, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Amit P. Sheth

Kno.e.sis Publications

Discovering complex and meaningful relationships, which we call Semantic Associations, is an important challenge. Just as ranking of documents is a critical component of today's search engines, ranking of relationships will be essential in tomorrow's semantic search engines that would support discovery and mining of the Semantic Web. Building upon our recent work on specifying types of Semantic Associations in RDF graphs, which are possible to create through semantic metadata extraction and annotation, we discuss a framework where ranking techniques can be used to identify more interesting and more relevant Semantic Associations. Our techniques utilize alternative ways of specifying the …


The Fcc Under Attack, Kerri Smith Aug 2003

The Fcc Under Attack, Kerri Smith

Duke Law & Technology Review

The Federal Communications Commission voted in a contentious three-two split to relax rules limiting ownership of TV stations, radio stations, and newspapers. Among its critics are members of Congress who may pass legislation reinstating the old rules. Others will likely file suit against the FCC in the hopes of overturning the decision. This article will discuss the current debate over media deregulation in light of the recent FCC order. Specifically, this ibrief focuses on concerns over media consolidation in the wake of the 'Clear Channelization' of American radio, and addresses the contrasting depictions of the current media landscape by advocates …

The Fcc And Congress Should Consider Consumer Rights When Making The Transition To Dtv, Frank Ing-Jye Chao Aug 2003

The Fcc And Congress Should Consider Consumer Rights When Making The Transition To Dtv, Frank Ing-Jye Chao

Duke Law & Technology Review

This ibrief discusses the copyright issue surrounding the transition into Digital Television. It proposes that the Federal Communications Commission should balance the copyright interests of all parties involved in the DTV transition. Creators of informative and entertaining works must be rewarded with incentives to create further works. Such incentives necessarily involve copyright protection for these content holders. Just as the rights of content holders should be protected, the public's right to access information and to freely express ideas needs to remain protected. Copyright laws, specifically the fair use doctrine, must be allowed to stand firm while maintaining flexibility in order …


Learning Mixture Models With The Latent Maximum Entropy Principle, Shaojun Wang, Dale Schuurmans, Fuchun Peng, Yunxin Zhao Aug 2003

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

Kno.e.sis Publications

We present a new approach to estimating mixture models based on a new inference principle we have proposed: the latent maximum entropy principle (LME). LME is different both from Jaynes’ maximum entropy principle and from standard maximum likelihood estimation. We demonstrate the LME principle by deriving new algorithms for mixture model estimation, and show how robust new variants of the EM algorithm can be developed. Our experiments show that estimation based on LME generally yields better results than maximum likelihood estimation, particularly when inferring latent variable models from small amounts of data.

Kno.e.sis Publications

We present a new statistical learning paradigm for Boltzmann machines based on a new inference principle we have proposed: the latent maximum entropy principle (LME). LME is different both from Jaynes maximum entropy principle and from standard maximum likelihood estimation. We demonstrate the LME principle BY deriving new algorithms for Boltzmann machine parameter estimation, and show how robust and fast new variant of the EM algorithm can be developed. Our experiments show that estimation based on LME generally yields better results than maximum likelihood estimation, particularly when inferring hidden units from small amounts of data.

A Visual Framework Invites Human Into The Clustering Process, Keke Chen, Ling Liu Jul 2003

A Visual Framework Invites Human Into The Clustering Process, Keke Chen, Ling Liu

Kno.e.sis Publications

Clustering is a technique commonly used in scientific research. The task of clustering inevitably involves human participation - the clustering is not finished when the computer/algorithm finishes but the user has evaluated, understood and accepted the patterns. This defines a human involved "clustering-analysis/evaluation" iteration. Instead of neglecting this human involvement, we provide a visual framework (VISTA) with all power of algorithmic approaches (since their result can be visualized), and in addition we allow the user to steer/monitor/refine the clustering process with domain knowledge. The visual-rendering result also provides a precise pattern for fast post-processing.


Press Controls In Wartime: The Legal, Historical, And Institutional Context, Stephen D. Cooper Jul 2003

Press Controls In Wartime: The Legal, Historical, And Institutional Context, Stephen D. Cooper

Communications Faculty Research

News coverage of warfare poses a dilemma for social systems with a free press, such as the United States. In an era of high-tech weaponry and nearly instantaneous global communications, conflict is inevitable between the obligation of the press to inform the general public and the obligation of the military to successfully conduct war. The importance of secrecy to the conduct of warfare heightens the issue in the current counterterrorism operations. The competitive advantage of live coverage raises the stakes in a crowded media market. The military’s control over newsgathering during the 1990-91 Persian Gulf War set off a controversy …

Adding Semantics To Web Services Standards, Kaarthik Sivashanmugam, Kunal Verma, Amit P. Sheth, John Miller Jun 2003

Adding Semantics To Web Services Standards, Kaarthik Sivashanmugam, Kunal Verma, Amit P. Sheth, John Miller

Kno.e.sis Publications

With the increasing growth in popularity of Web services, discovery of relevant Web services becomes a significant challenge. One approach is to develop semantic Web services where by the Web services are annotated based on shared ontologies, and use these annotations for semantics-based discovery of relevant Web services. We discuss one such approach that involves adding semantics to WSDL using DAML+OIL ontologies. Our approach also uses UDDI to store these semantic annotations and search for Web services based on them. We compare our approach with another initiative to add semantics to support Web service discovery, and show how our approach …
