WebThemeTM is an interactive new computer tool that provides a visual display of the common themes in collections of web-based documents, helping the user explore and understand large amounts of data with minimal reading. A web search for the phrase "information visualization" found hundreds of pages, which are plotted in this Galaxies visualization. Green dots represent individual web pages (with proximity indicating thematic similarity and greater distance signifying less similarity), orange circles represent a concentration of documents with a share theme (such as "time based design"), turquoise "theme clouds" contain documents similar in general content (such as "internet computing") and purple lines diagram the hyperlinks between documents. Associated analysis tools enable users to determine the "gist" of documents by displaying key words or access an entire document (as shown at left), or query the document collection and group results.
