A Preferential Tableaux Calculus For Circumscriptive Alco, Stephan Grimm, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Nonmonotonic extensions of description logics (DLs) allow for default and local closed-world reasoning and are an acknowledged desired feature for applications, e.g. in the Semantic Web. A recent approach to such an extension is based on McCarthy's circumscription, which rests on the principle of minimising the extension of selected predicates to close off dedicated parts of a domain model. While decidability and complexity results have been established in the literature, no practical algorithmisation for circumscriptive DLs has been proposed so far. In this paper, we present a tableaux calculus that can be used as a decision procedure for concept satisfiability …

A Best Practice Model For Cloud Middleware Systems, Ajith Harshana Ranabahu, E. Michael Maximilien

Kno.e.sis Publications

Cloud computing is the latest trend in computing where the intention is to facilitate cheap, utility type computing resources in a service-oriented manner. However, the cloud landscape is still maturing and there are heterogeneities between the clouds, ranging from the application development paradigms to their service interfaces,and scaling approaches. These differences hinder the adoption of cloud by major enterprises. We believe that a cloud middleware can solve most of these issues to allow cross-cloud inter-operation. Our proposed system is Altocumulus, a cloud middleware that homogenizes the clouds. In order to provide the best use of the cloud resources and make …

Context And Domain Knowledge Enhanced Entity Spotting In Informal Text, Daniel Gruhl, Meena Nagarajan, Jan Pieper, Christine Robson, Amit P. Sheth

Kno.e.sis Publications

This paper explores the application of restricted relationship graphs (RDF) and statistical NLP techniques to improve named entity annotation in challenging Informal English domains. We validate our approach using on-line forums discussing popular music. Named entity annotation is particularly difficult in this domain because it is characterized by a large number of ambiguous entities, such as the Madonna album “Music” or Lilly Allen’s pop hit “Smile”.

We evaluate improvements in annotation accuracy that can be obtained by restricting the set of possible entities using real-world constraints. We find that constrained domain entity extraction raises the annotation accuracy significantly, making an …

Hd Radio: Lost In Transition, Michael Huntsberger, Alan G. Stavitsky

Faculty Presentations

While many nations in the developed world have successfully implemented a variety of digital radio broadcasting technologies, U.S. Broadcasters have opted to implement a technology that is unique to North America: In-Band On-Channel broadcasting, marketed under the trade name HD Radio. While HD Radio offers improved audio quality and substantial convenience, broadcasters continue to struggle with issues of consumer awareness and use. This presentation examines some of the issues that have deferred the successful implementation of digital radio in the U.S.

Communication Rights, Digital Literacy And Ethical Individualism In The New Media Environment, Brian O'Neill

Conference Papers

Recent developments in European media policy have given priority to the notion that all citizens need to be digitally literate to fully participate in the emerging Information Society. Media literacy or digital literacy, it is argued, will be required to able to exercise informed choices, understand the nature of content and services and take advantage of the full range of opportunities offered by new communications technologies. Further, being media literate, citizens will be better able to protect themselves and their families from harmful or offensive material. The inclusion of media literacy within the Audiovisual Media Services Directive (Commission of the …

Ageism In Academic Librarianship, Melanie Chu

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

Background

Nearly one out of every ten librarians is under the age of thirty. The average age of a graduate student in library and information science is 30-35 years old. Between 2010-2020, 45% of librarians will reach the retirement age of 65 years old. The relative age of the profession will continue to decrease as retirements increase. Statistically, the population of young librarians is a growing minority.

Young, new librarians face age discrimination, including disrespectful treatment in the workplace and unrealistic expectations of performance. Ageism in academic libraries results in job dissatisfaction and loss of retention for these new librarians. …

Abstract

This article covers the revamp of a science library’s web area. The library’s web area contained outdated web pages, unused files, and an architecture that made it hard to maintain. All of these issues with the web area resulted in an examination and revamping of several aspects of all the files on the web area. Server statistics were used to determine the usage of the files in the library’s web area. Files containing textual information were categorized according to their topic and the usage of each topic area was examined to determine the distribution of usage amongst the topic …

Embedding An Im [Instant Messaging] Widget In Research Databases: Helping Users At Their Point-Of-Need, Kwabena Sekyere

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

Introduction

The rapid growth of internet users has made libraries eager to introduce online services for this new community, in addition to their traditional reference services. Virtual reference service has become a convenient and easily accessible option for the online community, particularly with increasing amounts of libraries resources now available electronically as well (Lou, 2007).

Virtual reference began in many libraries as email reference service (Janes, 2002) with a move to live chat reference as technology advanced. These live reference services were offered through chat software developed in-house or by vendors. Due to the high cost of purchasing and maintaining …

Open House In The Ivory Tower: Public Programming At An Academic Library, Rochelle Smith, Ben Hunter

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

Abstract

Public programming, a frequently used outreach tool for public libraries, is far less common in academic libraries. This article examines the University of Idaho Library’s efforts to attract both university and community members with public programming, delving into detail for three specific grant-funded discussion series: one on Jewish literature, one on graphic novels, and one on jazz. Strategies for location selection, advertising, scheduling and funding are all discussed with commentary on what worked well, what didn’t, and how public programming fits into the mission of an academic library.

Using A Permanent Usability Team To Advance User-Centered Design In Libraries, Jane Nichols, Alison M. Bobal, Susan Mcevoy

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

Abstract

Usability, user studies, and evaluating user experiences have been a part of academic libraries for many years. In the last 20 years libraries have created ad hoc usability teams to do user studies. Oregon State University (OSU) Libraries started its ongoing team in 2006, resulting in an increased focus on user experience throughout the libraries. This article explores the team’s history from formation to work it took on. The merits and challenges usability teams bring to an organization are also discussed. To date the literature describes usability methods and shares findings from libraries’ usability studies but none discusses benefits …

If You Build It, They May Not Come: The Case Of Questionpoint, Lynette Ralph

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

Abstract

The Knowledge Base (KB) of QuestionPoint (QP) is a Knowledge Management (KM) tool capable of capturing the collective knowledge of reference librarians for future use. The goal of the study was to determine if this KB is an effective KM tool. Descriptive research was the methodology used and included an unobtrusive study, a survey instrument, and interviews. This study revealed that despite the technological capabilities of this KB, librarians who had access to the system failed to utilize it.

Permanent Electronic Access To Government Information: A Study Of Federal, State, And Local Documents, Claudene Sproles, Angel Clemons

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

[First two paragraphs]

Even before the conception of electronic-only documents, providing permanent public access to government information was challenging. Since 1813, federal depository libraries have acquired and maintained tangible items to ensure continued access for the public. Fugitive documents, or government-produced information which escapes distribution through the Federal Depository Library System (FDLP), have always been a major concern. In our current environment, where the vast majority of government information is distributed electronic-only, this problem has only worsened. That, coupled with the ability to completely destroy electronic documents with the click of a mouse, has made the task of finding and …

“Best K”: Critical Clustering Structures In Categorical Datasets, Keke Chen, Ling Liu

Kno.e.sis Publications

The demand on cluster analysis for categorical data continues to grow over the last decade. A well-known problem in categorical clustering is to determine the best K number of clusters. Although several categorical clustering algorithms have been developed, surprisingly, none has satisfactorily addressed the problem of best K for categorical clustering. Since categorical data does not have an inherent distance function as the similarity measure, traditional cluster validation techniques based on geometric shapes and density distributions are not appropriate for categorical data. In this paper, we study the entropy property between the clustering results of categorical data with different K …

Tableau Algorithm For Concept Satisfiability In Description Logic Alch, Satya S. Sahoo, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The provenir ontology is an upper-level ontology to facilitate interoperability of provenance information in scientific applications. The description logic (DL) expressivity of provenir ontology is ALCH, that is, it models role hierarchies (H) (without transitive roles and inverse roles). Even though the complexity results for concept satisfiability for numerous variants of DL such as ALC with transitively closed roles (ALC_R+ also called S), inverse roles SI, and role hierarchy SHI have been well-established, similar results for ALCH has been surprisingly missing from the literature. Here, we show that the complexity of the concept satisfiability problem for the ALCH variant …

Virtually There: Social Structure Over Time And Space, Wayne Erik Rysavy

Boise State University Theses and Dissertations

Communication is both process and art. It is the vehicle through which we share our thoughts and feelings as much as it is a creative activity resulting in the production of new meanings and ways of knowing. While we commonly understand communication as a continual process of reception and interpretation, new electronic media continue to extend our knowledge of what constitutes communication and how we characterize communication. Challenging the longstanding assumptions of fixed and positioned ways of knowing, studies with new electronic media accentuate the burgeoning contrast between the authority and stability of the written word and the mutability of …
