The Web is revolutionizing the way citizens interact with businesses and government agencies. Almost all key functions of modern society are being reshaped to exploit opportunities the Web opens. As part of an effort to improve government-citizen interactions, government agencies are providing a wide spectrum of online services. Virginia Tech is collaborating with the Virginia Department for the Aging (VDA) on a project called WebSenior. A middleware infrastructure, WebSenior automatically delivers e-government services customized for seniors. It uses ontologies to automatically generate Web services customized to senior citizens' needs and government program laws and regulations.
