Abstract
This dissertation is comprised of three papers. The first two papers investigate how the various informational elements of online reviews, including their textual portion, impact the perceived helpfulness of those reviews. The third paper proposes a methodological refinement to improve the process by which reviews and reviewers are ranked with respect to their helpfulness and has potential applicability in fake review detection. These three papers utilize natural language processing methods, including Latent Semantic Analysis (LSA), which allows for the automatic analysis of large amounts of text with minimal human intervention.
