Abstract

Multi-dimensional Visualization (hereafter, "MDV") is to explore ways of graphically conveying useful information about digital library content to a user without confusing or overwhelming them. It seeks to present a user with an interactive graph of numeric and textual information gleaned from a semantic clustering system. Ultimately, the graphs will provide users with a system for efficient navigation through a document corpus. By graphically moving through a hierarchy of clusters, casual users and collection developers will browse through large collections of documents, understanding the arrangement of records at multiple levels of specificity. It is important that the browse interface be simple and intuitive for researchers with potentially no technical background. Through user feedback and focus groups, the system will continue to be tuned to researchers' needs and expectations.
