Design and Development of a Metadata-Driven Search Tool for use with Digital Recordings
It is becoming more common for researchers to use existing recordings as a source for data rather than to generate new media for research. Prior to the examination of recordings, data must be extracted from the recordings and the recordings must be described with metadata to allow users to search …

Investigation on Applying Modular Ontology to Statistical Language Model for Information Retrieval
The objective of this research is to provide a novel approach to improving retrieval performance by exploiting Ontology with the statistical language model (SLM). The proposed methods consist of two major processes, namely ontology-based query expansion (OQE) and ontology-based document …

By any other name: a study of library user comprehension of subject headings
<p>The current research examined library users and their use of subject headings in library catalog searches. It also examined how effective library catalog searches were for users. A survey was designed to give the researcher an idea of what search terms the public used to search library catalogs. …

Multi-language code search
Searching for specified code patterns is a common component in many types of programming tools for any language. Unfortunately, there is no code search approach that produces application-friendly search results and supports multiple languages under the same system. This work presents a program …

Can housing policy address spatial inequality? : innovations in policy and politics to expand access to opportunity neighborhoods
While research has demonstrated that low-poverty neighborhoods can improve economic outcomes for low-income children, policymakers have few scalable solutions to help families access those areas. In this dissertation, I present three innovations in policy and politics aimed at improving access to …

DIVIDE TO CONQUER: PRIORITIZATION AND SEGMENTATION IN US&R SEARCH OPERATIONS
Urban Search and Rescue (US&R) teams regularly deploy to areas affected by large-scale disasters. The intention is for US&R teams to search the affected areas, rescue people in danger, and render aid. Determining where to conduct searches is a problem with unique variables for every incident. There …
