A GraphXML description of query maps

Website maps are becoming one of the most important applications of graph drawing and information visualization techniques. However, the user has often struggled with web graphs returned from web search agents. To efficiently manage the visualization of these graphs it also occurs to take advantage from the flexibility of XML language. GraphXML format is a standard proposed for the information visualization of generic graphs. In this work, we focus on query graphs in. the sense of web graphs that are the semantics of WebSQL query language. In particular, we give a GraphXML description of query graphs in a way that visual properties like colouring scheme for node relevance visualization ("hot pages") can be included. As application we show some example of query maps returned by our web search tool VSEARCH that are obtained in an easy way via a Javascript view program.
