" + "To break this chicken-and-egg problem, thus enabling more flexible information " + "access, we have created a web browser extension called Piggy Bank that lets " + "users make use of Semantic Web content within Web content as users browse the " + "Web.

" + "To further improve this Semantic Web experience, we have created Semantic " + "Bank, a web server application that lets Piggy Bank users share the Semantic " + "Web information they have collected, enabling collaborative efforts to build sophisticated " + "Semantic Web information repositories through simple, everyday's " + "use of Piggy Bank.
