April Kontostathis currently holds an Associate Professor position at Ursinus College in Collegeville, PA. She obtained her Ph.D. in Computer Science from Lehigh University. Her doctoral dissertation, A Term Co-occurrence Based Framework for Understanding LSI: Theory and Practice, developed a theoretical model for understanding Latent Semantic Indexing (LSI), a retrieval system that is based on the values produced by taking a Partial Singular Value Decomposition (PSVD) of the term-by-document matrix. Dr. Kontostathis has written numerous articles that describe methods for determining the most critical values in the reduced dimensionality matrix, and improving the efficiency and effectiveness of LSI. While Dr. Kontostathis’ primary research interest is in the theory and practice of information retrieval and textual data mining, she also has an investment in undergraduate research, and has co-authored several articles with her students at Ursinus College.
