Automated Classification Of The Narrative Of Medical Reports Using Natural Language Processing, Ira J. Goldstein
Automated Classification Of The Narrative Of Medical Reports Using Natural Language Processing, Ira J. Goldstein
Legacy Theses & Dissertations (2009 - 2024)
In this dissertation we present three topics critical to the document level classification of the narrative in medical reports: the use of preferred terminology in light of the presence of synonymous terms, the less than optimal performance of classification systems when presented with a non-uniform distribution of classes, and the problems associated with scarcity of labeled data when presented with an imbalance of classes in the data sets.
Toward A Policy Framework For The Design Of Economic Information Packages, Andrew Whitmore
Toward A Policy Framework For The Design Of Economic Information Packages, Andrew Whitmore
Legacy Theses & Dissertations (2009 - 2024)
The emergence of product certifications such as "organic," "fair trade" and "shade grown" has gone far to introduce non-price related product information back into the consumer decision making process thereby reducing information asymmetries and improving market outcomes. Recently, these certifications have been supplemented by the emergence of several web-based consumer decision support systems that are designed to disseminate non-price product information to consumers. Like printed product labels, these new web-based systems present the same informational cues to each consumer regardless of his or her preference for the information and they rate products with fixed weights that are not customized to …
The Schenectady Virtual Community : Exploring The Ecology Of Political Discourse In A Local Context, Andrea B. Baker
The Schenectady Virtual Community : Exploring The Ecology Of Political Discourse In A Local Context, Andrea B. Baker
Legacy Theses & Dissertations (2009 - 2024)
From Facebook to Twitter, ordinary citizens' use of social media to discuss, organize, and participate in the political process continues to grow in popularity (Davis, 2005; Rainie, 2005; Kohut, 2008). Researchers interested in this area have explored the demographics, patterns of behavior and motives of participants in online communities (Stromer-Galley, 2002, 2003), the dynamics of the online discussions (Dahlberg, 2001; Davis, 2005; Wilhelm, 2000), the effect of online participation on other forms of political activity (Brunsting, 2002; Kavanaugh & Patterson, 2001), and more recently the relationship between social media and the conventional press (Hiler, 2002; Park, 2004; Cornfield, 2006; Lenhart …
Toward A Theory-Based Natural Language Capability In Robots And Other Embodied Agents : Evaluating Hausser's Slim Theory And Database Semantics, Robin Kowalchuk Burk
Toward A Theory-Based Natural Language Capability In Robots And Other Embodied Agents : Evaluating Hausser's Slim Theory And Database Semantics, Robin Kowalchuk Burk
Legacy Theses & Dissertations (2009 - 2024)
Computational natural language understanding and generation have been a goal of artificial intelligence since McCarthy, Minsky, Rochester and Shannon first proposed to spend the summer of 1956 studying this and related problems. Although statistical approaches dominate current natural language applications, two current research trends bring renewed focus on this goal. The nascent field of artificial general intelligence (AGI) seeks to evolve intelligent agents whose multi-subagent architectures are motivated by neuroscience insights into the modular functional structure of the brain and by cognitive science insights into human learning processes. Rapid advances in cognitive robotics also entail multi-agent software architectures that attempt …
Mobile Technologies & Socio-Economic Opportunities For Disadvantaged Women : A Study Of Information Behavior In A Developing Nation Context, Devendra Dilip Potnis
Mobile Technologies & Socio-Economic Opportunities For Disadvantaged Women : A Study Of Information Behavior In A Developing Nation Context, Devendra Dilip Potnis
Legacy Theses & Dissertations (2009 - 2024)
Information and communication technologies (ICTs) have been championed by the United Nations and others as one of the key media to open up socio-economic opportunities for disadvantaged populations. Studies lead us to believe that after being introduced to ICTs, users' information behavior changes, enabling them to benefit from socio-economic opportunities. Using Wilson's (1997) Revised General Model of Information Behavior (Model), the dissertation explored the role of cell phones - the fastest spreading information and communication technology (ICT) - in shaping the information behavior of disadvantaged population, with its implications on socio-economic opportunities.
Polymorphic Attacks And Network Topology : Application Of Concepts From Natural Systems, Prahalad Rangan
Polymorphic Attacks And Network Topology : Application Of Concepts From Natural Systems, Prahalad Rangan
Legacy Theses & Dissertations (2009 - 2024)
The growing complexity of interactions between computers and networks makes the subject of network security a very interesting one. As our dependence on the services provided by computing networks grows, so does our investment in such technology. In this situation, there is a greater risk of occurrence of targeted malicious attacks on computers and networks, which could result in system failure. At the user level, the goal of network security is to prevent any malicious attack by a virus or a worm. However, at the network level, total prevention of such malicious attacks is an impossible and impractical objective to …
The Myth Of Fragmentation : Assessing Political Information Online, Alexis Marie Wichowski
The Myth Of Fragmentation : Assessing Political Information Online, Alexis Marie Wichowski
Legacy Theses & Dissertations (2009 - 2024)
Internet technology has provided people with unprecedented abilities to filter the information they encounter, leading many scholars to fear that people will be exposed to less diversity of perspectives and fragment into homogeneous interest groups. Exposure to a wide range of topics and perspectives about political information in particular is considered necessary by many scholars in order for citizens to be informed participants in democratic life. However, fears that the Internet leads to fragmentation rest on three assumptions: 1. online, opportunities for unintended encounters with a diversity of information are limited, 2. people primarily pursue narrow interests when consuming online …
Consumer Responses In Sales To Multiple Media Advertising Exposures : The Impact Of Synergy Based On A Study Of Project Apollo Single Source Data, Leslie Wood
Legacy Theses & Dissertations (2009 - 2024)
The primary focus of this dissertation is to answer the question: how does exposure to advertising affect purchasing behavior, and in particular, how does synergy resulting from exposure to advertising in multiple media influence purchasing behavior? This is a critical piece of information in the business decision process of media planning. It determines which media to include in a media plan and how to allocate a limited budget across media in order to optimize the return on investment from advertising. This question has been studied in many ways since it has been a central question for the advertising industry for …
Socio-Technical Processes In Interorganizational Emergency Response And Recovery Process At The World Trade Center, Bahadir Akcam
Socio-Technical Processes In Interorganizational Emergency Response And Recovery Process At The World Trade Center, Bahadir Akcam
Legacy Theses & Dissertations (2009 - 2024)
This research explores the socio-technical processes in interorganizational collaboration by extending and elaborating a generic dynamic theory. The existing generic dynamic theory offers dynamic hypotheses about causal relationships between social processes and social accumulations based on a study of interagency information integration initiatives. The current study expands this theory and elaborates upon it using interview dataset from interagency collaboration during the response and recovery process following the World Trade Center (WTC) attack on September 11, 2001. Researchers at the Center for Technology in Government interviewed 29 responders in 2002 and 2003 to explore interagency collaboration in the context of information, …
Qualitative Information In Annual Reports & The Detection Of Corporate Fraud : A Natural Language Processing Perspective, Sunita Goel
Legacy Theses & Dissertations (2009 - 2024)
High profile cases of fraudulent financial reporting such as those that occurred at Enron and WorldCom have shaken public confidence in the U.S. financial reporting process and have raised serious concerns about the roles of auditors, regulators, and analysts in financial reporting. In order to address these concerns and restore public confidence, the Sarbanes-Oxley Act (SOX) of 2002 was enacted. However, SOX has not lived up to its promise. Numerous cases of fraudulent financial reporting have surfaced in the post-SOX era. So far, the major thrust of research has been on examining fraud that has already been discovered. This dissertation …
The Effects Of Leadership And Authority On Cross-Boundary Information Sharing In Response To Public Health Crises : A Comparative Study Between The United States And Jordan, Fawzi H. Mulki
Legacy Theses & Dissertations (2009 - 2024)
Regardless of national context, cross-boundary information sharing is inevitably entangled with issues of jurisdiction, leadership, and authority. This study answers the question: "to what extent do officials in the United States and Jordan share key leadership characteristics and how are officials' uses of authority similar or different?"
