Graph Summaries For Subgraph Frequency Estimation, Angela Maduko, Kemafor Anyanwu, Amit P. Sheth, Paul Schliekelman

Kno.e.sis Publications

A fundamental problem related to graph structured databases is searching for substructures. One issue with respect to optimizing such searches is the ability to estimate the frequency of substructures within a query graph. In this work, we present and evaluate two techniques for estimating the frequency of subgraphs from a summary of the data graph. In the first technique, we assume that edge occurrences on edge sequences are position independent and summarize only the most informative dependencies. In the second technique, we prune small subgraphs using a valuation scheme that blends information about their importance and estimation power. In both …

Defeasible Inference With Circumscriptive Owl Ontologies, Stephan Grimm, Pascal Hitzler

Computer Science and Engineering Faculty Publications

The Web Ontology Language (OWL) adheres to the openworld assumption and can thus not be used for forms of nonmonotonic reasoning or defeasible inference, an acknowledged desirable feature in open Semantic Web environments. We investigate the use of the formalism of circumscriptive description logics (DLs) to realise defeasible inference within the OWL framework. By example, we demonstrate how reasoning with (restricted) circumscribed OWL ontologies facilitates various forms of defeasible inference, also in comparison to alternative approaches. Moreover, we sketch an extension to DL tableaux for handling the circumscriptive case and report on a preliminary implementation.

Information Technology Acceptance In South Africa: An Investigation Of Perceived Usefulness, Perceived Ease Of Use, And Actual System Use Constructs, Udo Richard Averweg

The African Journal of Information Systems

Information technology (IT) acceptance studies pay much attention to issues of significance in assessing the contributions of variables explaining IT usage for decision-making in organizations. Davis’ Technology Acceptance Model (TAM) states that Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) are the two factors that govern the adoption and use of information technology. Actual System Use (behavior) consists of the number of times of systems use. The author conducted a survey of 31 organizations in KwaZulu/Natal, a region in South Africa, which implemented an Executive Information System (EIS). A validated survey instrument was administered to an EIS stakeholder in …

A Framework To Support Spatial, Temporal And Thematic Analytics Over Semantic Web Data, Matthew Perry, Amit P. Sheth

Kno.e.sis Publications

Spatial and temporal data are critical components in many applications. This is especially true in analytical applications ranging from scientific discovery to national security and criminal investigation. The analytical process often requires uncovering and analyzing complex thematic relationships between disparate people, places and events. Fundamentally new query operators based on the graph structure of Semantic Web data models, such as semantic associations, are proving useful for this purpose. However, these analysis mechanisms are primarily intended for thematic relationships. In this paper, we describe a framework built around the RDF data model for analysis of thematic, spatial and temporal relationships between …

A Study Of The Effects Technology Has On Social Capital, Kyle Douglas Lanoue

All-Inclusive List of Electronic Theses and Dissertations

Although the concept of social capital in many respects remains shrouded in confusion and misunderstanding, it does present a foundation for describing and understanding the powerful nature of trust and relationships in the education environment. This study was primarily about adding an angle to the study of human relationships that investigates the mechanisms that technology provides for social investments. Specifically, the purpose of this study was to understand the effects technology has on social capital in public K-12 schools. lll The researcher has provided evidence from both the literature review and the responses from 42 practicing principals regarding the habits …

Reminiscences: Impact Of Textiles And Apparel Technology On Our Lives, Ann Beth Presley, Martha C. Jenkins

Applied Human Sciences

Women's perceptions of technological changes in textiles and apparel and how the changes have affected daily life were examined using the transmissive reminiscence technique. Technological advances do contribute to use of less time and effort and offer a greater variety of products, but the products often have a shorter life expectancy or are kept in inventory for a shorter time because it is more expedient to replace rather than repair or recycle textile and clothing items. Care must be taken to cultivate cohesive relationships within the family and teach values that were once inherent in textiles/ apparel tasks. Otherwise advances …

The Making Of A Social Librarian: How Blogs, Wikis And Facebook Have Changed One Librarian And Her Job, Jennifer Kelley

Library Scholarship

This paper explores the evolution of the author’s identity as a librarian, from a tech-ignorant/tech-phobic library school graduate to a librarian teaching faculty, staff, students, community members and administrators the value of collaborative software.

According to Technorati, the blog search engine, there are 244 blogs that primarily concern themselves with libraries and so-called 2.0 technologies. The blogs range from the well known Tame the Web and Shifted Librarian to library students attempting to sort out the deluge of information on blogs, wikis, RSS feeds, social networking services and how these applications and services help, hinder, harm or haunt libraries and …

Artist Ranking Through Analysis Of On-Line Community Comments, Julia Grace, Daniel Gruhl, Kevin Haas, Meenakshi Nagarajan, Christine Robson, Nachiketa Sahoo

Kno.e.sis Publications

We describe an approach to measure the popularity of music tracks, albums and artists by analyzing the comments of music listeners in social networking online communities such as MySpace. This measure of popularity appears to be more accurate than the traditional measure based on album sales figures, as demonstrated by our focus group study. We faced many challenges in our attempt to generate a popularity ranking from the user comments on social networking sites, e.g., broken English sentences, comment spam, etc. We discuss the steps we took to overcome these challenges and describe an end to end system for generating …

Oai/Pmh Metadata Conformance To Dlf/Aquifer Mods Guidelines, Colin J. Koteles

Library Scholarship

The DLF/Aquifer Implementation Guidelines for Shareable MODS Records were created to facilitate the creation of rich, sharable metadata for use in aggregated digital humanities collections. While guideline creators recognize most data providers do not meet criteria set forth in this document, this study attempts to quantify current levels of conformance to the base requirements set forth by DLF/Aquifer MODS guidelines. By analyzing collections for which MODS records are currently available to OAI-PMH service providers, predictions can be made as to both the nature and extent of future normalization processes required by service providers and the nature and extent of training …

Beating The Odds With The Insider’S Scoop: Tips And Tricks From The Library Secrets! Librarian, Jennifer Kelley

Library Scholarship

Is the research process an “unbeatable” game, where the odds are always against the student? We see our students sitting blankly in front of computer screens, dropping search terms into databases like coins into one-armed bandits, hoping for the jackpot—full-text articles on their subject seemingly elusive as three cherries in a row.

Games generally have a learning curve—the more you play, the better you become. Increasingly, however, gamers turn to tips and tricks resources for shortcuts, strategies and cheat codes that can give them the edge and propel them to the next level. When it comes to research, the stakes …

Chapter One: Beneath The Spanish Moss: The World Of The Root Doctor, Jack G. Montgomery Jr.

DLTS Faculty Publications

The spiritual practice of the Shaman is most likely the oldest spiritual tradition on Earth. Shamanism is a way in which humanity has sought a psychic connection to the world of healing, life and death, as well as a sense of social and individual balance. It is a complex psychological grammar that allows the Shaman to function in both the conventional and an alternative "spirit" view of reality. Shamanisn has been a part of American culture since the colonial settlement and continues today despite technology and modern scientific rationalism. This chapter is a brief social history of the African-American shamanic …

Traveling The Semantic Web Through Space, Time, And Theme, Amit P. Sheth, Matthew Perry

Kno.e.sis Publications

In this installment of Semantics and Services, we further develop the idea of spatial, temporal, and thematic (STT) processing of semantic Web data and describe the Web infrastructure needed to support it. Starting from Ramesh Jain's vision of the EventWeb as a view of what's possible with a Web that better accommodates all three dimensions of event-related information (thematic, spatial, and temporal), we outline the architecture needed to support it and current research that aims to realize it.
