Biography:
Bob Losee has a doctorate from the University of Chicago. His primary interests are in the study of information itself, the study of organizing and retrieving information, and library operations.  In all of these areas, he is interested in all domains.  Research in the area of information has included a recent book, Information From Processes: Information Creation, Use, and Representation, defining information.  Along with this book is a programming language that can be used to study information applications.   In the area of Information Organization, his primary research emphases are in organizing information in an optimal manner for physical and electronic ordering of documents,  along with determining how and when metadata and subject headings help improve retrieval performance.  Most of Bob’s Information Retrieval research focuses on the relationships between document and query characteristics and their effect on retrieval performance.  Unlike much experimental work, this research produces broad principles that can be applied to any situation where the assumptions of the model are met, and can be used to compute the exact performance that will be obtained.
