Using Ontology-Based Approaches To Representing Speech Transcripts For Automated Speech Scoring, Miao Chen

School of Information Studies - Dissertations

Text representation is a process of transforming text into some formats that computer systems can use for subsequent information-related tasks such as text classification. Representing text faces two main challenges: meaningfulness of representation and unknown terms. Research has shown evidence that these challenges can be resolved by using the rich semantics in ontologies. This study aims to address these challenges by using ontology-based representation and unknown term reasoning approaches in the context of content scoring of speech, which is a less explored area compared to some common ones such as categorizing text corpus (e.g. 20 newsgroups and Reuters).

The Public Library As Health Information Resource?, Mary Grace Flaherty

School of Information Studies - Dissertations

Public libraries have adapted a variety of services into their institutional missions, including: promoting early literacy, publicly available Internet access, children's summer reading programs, and the dissemination of tax forms. Libraries are disproportionately rural institutions, often serving people with limited health care access. Thus, by public demand they have evolved to become important resources for rural health consumers to acquire information. Some public libraries have approached this role by subscribing to health databases, or by providing a link on their homepage to a health resource such as MedlinePlus, but most have undertaken little organizational change to meet growing patron demand. …

Social Technologies And Informal Knowledge Sharing Within And Across Organizations, Jarrahi Mohammad Hosein

School of Information Studies - Dissertations

This doctoral dissertation is focused on both empirical and conceptual contributions relative to the roles social technologies play in informal knowledge sharing practices, both within and across organizations. Social technologies include (a) traditional social technologies (e.g., email, phone and instant messengers), (b) emerging social networking technologies commonly known as social media, such as blogs, wikis, major public social networking sites (e.g., Facebook, Twitter and LinkedIn), and (c) enterprise social networking technologies controlled by a host organization ( e.g., SocialText). The rapid uptake of social technologies, combined with growing interest in their broader social implications, raises pertinent questions about uses for …

A Theory Of Ict User Types: Exploring Domestication And Meaning Of Icts Through Comparative Case Studies, Johanna L. H. Birkland

School of Information Studies - Dissertations

The population in the United States is aging, with a predicted 147% increase in the number of older adults (those over age 65) from 2000- 2050 (U.S. Census Bureau, 2008). At the same time, Information and Communication Technologies (ICTs) are increasingly being used in work, leisure, and government. Despite these two trends towards an aging population and greater ICT use, very little is known about if and how older adults are using ICTs in their everyday lives (Birkland & Kaarst-Brown, 2011). Despite many calls for researchers to take a wider perspective (Bouwhuis, 2006; van Bronswijk, et al., 2009), most studies …

An Investigation Of Digital Reference Interviews: A Dialogue Act Approach, Keisuke Inoue

School of Information Studies - Dissertations

The rapid increase of computer-mediated communications (CMCs) in various forms such as micro-blogging (e.g. Twitter), online chatting (e.g. digital reference) and community- based question-answering services (e.g. Yahoo! Answers) characterizes a recent trend in web technologies, often referred to as the social web. This trend highlights the importance of supporting linguistic interactions in people's online information-seeking activities in daily life - something that the web search engines still lack because of the complexity of this hu- man behavior. The presented research consists of an investigation of the information-seeking behavior of digital reference services through analysis of discourse semantics, called dialogue acts, …

Design Science In Human-Computer Interaction: A Model And Three Examples, Nathan Prestopnik

School of Information Studies - Dissertations

Humanity has entered an era where computing technology is virtually ubiquitous. From websites and mobile devices to computers embedded in appliances on our kitchen counters and automobiles parked in our driveways, information and communication technologies (ICTs) and IT artifacts are fundamentally changing the ways we interact with our world. Indeed, the world itself changing, becoming ever more artificial. It is a designed world that we have created for ourselves.

Human-computer interaction (HCI) scholars are concerned with the interactions that occur between people and technology in this new world: how do IT artifacts impact the human experience, and how can knowledge …

Towards A Service-Oriented Enterprise: The Design Of A Cloud Business Integration Platform In A Medium-Sized Manufacturing Enterprise, Paul John Stamas

School of Information Studies - Dissertations

This case study research followed the two-year transition of a medium-sized manufacturing firm towards a service-oriented enterprise. A service-oriented enterprise is an emerging architecture of the firm that leverages the paradigm of services computing to integrate the capabilities of the firm with the complementary competencies of business partners to offer customers with value-added products and services. Design science research in information systems was employed to pursue the primary design of a cloud business integration platform to enable the secondary design of multi-enterprise business processes to enable the dynamic and effective integration of business partner capabilities with those of the enterprise. …

The Impact Of Cultural Assumptions About Technology On Choctaw Heritage Preservation And Sharing, Jake A. Dolezal

School of Information Studies - Dissertations

Neither the effects of information and communication technology (ICT) on culture nor the cultural roles of ICT are widely understood, particularly among marginalized ethno-cultures and indigenous people. One theoretical lens that has received attention outside of Native American studies is the theory of Information Technology Cultures, or "IT Culture," developed by Kaarst-Brown. This theory was a groundbreaking and foundational way to understand underlying assumptions about IT and the conflicts surrounding IT use. Kaarst-Brown identified five archetypal cultural patterns or sets of "underlying cultural assumptions" about IT that impacted strategic use, conflict, and technology innovation. These dimensions included assumptions about the …

Institutional And Individual Influences On Scientists' Data Sharing Behaviors, Youngseek Kim

School of Information Studies - Dissertations

In modern research activities, scientific data sharing is essential, especially in terms of data-intensive science and scholarly communication. Scientific communities are making ongoing endeavors to promote scientific data sharing. Currently, however, data sharing is not always well-deployed throughout diverse science and engineering disciplines. Disciplinary traditions, organizational barriers, lack of technological infrastructure, and individual perceptions often contribute to limit scientists from sharing their data. Since scientists' data sharing practices are embedded in their respective disciplinary contexts, it is necessary to examine institutional influences as well as individual motivations on scientists' data sharing behaviors. The objective of this research is to investigate …

Utilization And Value Of Public Sector Information For Knowledge Development: The Case Of South Africa, Raed M. Sharif

School of Information Studies - Dissertations

Although there appears to be a broad recognition of the key role that Public Sector Information (PSI) can play in the development of societies, there are still significant gaps in our understanding of how PSI is actually being utilized and of its wider societal value, especially in developing countries. The overarching goal of this dissertation was to analyze the PSI utilization process within the knowledge creation context and the factors and conditions that affect its value and usability from the user perspective. More specifically, the thesis investigates the PSI-related factors and conditions that facilitate or hinder the utilization process, as …
