Miles Efron is a recent graduate of the doctoral program in Information Science at the University of North Carolina-Chapel Hill. His research focuses on information retrieval, specifically empirical methods for concept extraction in automatic text indexing. With the OSRT he has helped develop the Open Source Metadata Framework, a metadata standard that will improve classification and resource discovery within the archives of the Linux Documentation Project and in other open source projects.

Unpublished doctoral dissertation, University of North Carolina, Chapel Hill. Latent Semantic Indexing (LSI) extends Salton's vector space model (VSM) of information retrieval, using dimensionality reduction to construct a statistical model of the relationships among the terms in a document collection. This dissertation pusues the viability of five statistical methods for estimating the optimal dimensionality of LSI systems. |
