The Tetherless World Mobile Wine Agent is a Semantic Web application for making wine and food recommendations to users. In order to make the interface easier for users, instances are generated through a common interface that uses data from the underlying ontology to drive user interaction. The agent is being integrated with social applications, such as Facebook and Twitter, to allow users to leverage and share gener- ated content with other individuals on the World Wide Web. Anyone can contribute data by constructing an RDF graph and making it available over the web in XML, which the agent will read and incorporate into its internal graph. Thus, users of the wine agent can access menus published in RDF on the web. By bringing together semantics, data sharing, and extensibility, the Mobile Wine Agent demonstrates how semantics and user interactions can work in tandem to grow the Semantic Web. 1 Introduction The primary goal of the Semantic Web is to redefine how we store, access, and think about dat [1]. This new approach to data, juxtaposed with the proprietary APIs of social web applications such as Facebook and Twitter, requires devel- opers and data providers alike to rethink the openness of data. The Tetherless World Mobile Wine Agent is an application which uses Semantic Web tech- nologies to describe food and wine pairings while providing social interaction and recommendation sharing via current social web platforms such as blogging, Facebook, and Twitter. In this paper, we will describe the Mobile Wine Agent’s ontology-sensitive interface for generating instances and classes, the underlying command architec- ture system for the agent, and how the agent integrates with social web applica- tions, specifically Twitter and Facebook. Additionally, we will highlight how to utilize existing web technologies to provide a seamless user experience with the Wine Agent. Wine and food are a rich domain and the history of recommender systems goes back almost twenty years [2] and has evolved with the tools used to repre- sent knowledge [3, 4]. Given the ubiquity of the mobile phone and the projected
