TAILIEUCHUNG - Piggy Bank: Experience the Semantic Web Inside Your Web Browser

Semantic Bank shares a very similar architecture to the Java part of Piggy Bank. They both make use of the same servlet that serves their DHTML-based faceted browsing user interface. They make use of several profiles for segregating data models. Semantic Bank gives each of its subscribed members a different profile for persisting data while it keeps another profile where “published” information from all members gets mixed together. Semantic Bank listens to HTTP POSTs sent by a user’s piggy bank to upload his/her data. All of the uploaded data goes into that user’s profile on the Semantic Bank, and those items. | Piggy Bank Experience the Semantic Web Inside Your Web Browser David Huynh1 Stefano Mazzocchi2 David Karger1 1MIT Computer Science and Artificial Intelligence Laboratory The Stata Center Building 32 32 Vassar Street Cambridge MA 02139 USA dfhuynh karger @ 2MIT Digital Libraries Research Group 77 Massachusetts Ave. Cambridge MA 02139 USA stefanom@ Abstract. The Semantic Web Initiative envisions a Web wherein information is offered free of presentation allowing more effective exchange and mixing across web sites and across web pages. But without substantial Semantic Web content few tools will be written to consume it without many such tools there is little appeal to publish Semantic Web content. 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. Wherever Semantic Web content is not available Piggy Bank can invoke screenscrapers to re-structure information within web pages into Semantic Web format. Through the use of Semantic Web technologies Piggy Bank provides direct immediate benefits to users in their use of the existing Web. Thus the existence of even just a few Semantic Web-enabled sites or a few scrapers already benefits users. Piggy Bank thereby offers an easy incremental upgrade path to users without requiring a wholesale adoption of the Semantic Web s vision. 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. Introduction The World Wide Web has liberated information from its physical containers books journals magazines newspapers etc. No longer physically bound information can flow faster .
