SemanticXO: connecting the XO with the World’s largest information network Christophe Gu´ eret and Stefan Schlobach Vrije Universiteit Amsterdam, Amsterdam (Nederlands) {c.d.m.gueret,k.s.schlobach}@vu.nl Abstract. The XO, powered by a dedicated graphical environment Sugar, is a low cost, robust and connected laptop suitable for usage in devel- oping countries. The Web of Linked Data is the largest decentralized information network ever crafted so far, containing factual information about millions of “things”. The community project SemanticXO is about connecting the two, providing Sugar with dedicated tools to harness the power of the Web of Linked Data. In this paper, we introduce the project, its current status and the goals. Key words: Semantic Web, Linked Data, Sugar, SemanticXO, Seri- ous Games 1 Introduction Over the last decades, the invention of network protocols enabled data sharing among groups of locally connected computers. The birth of the Internet con- nected all these local networks into one giant network upon which the World Wide Web (WWW) was built as a global, decentralized, publication system. As proven by its success, the publication of documents on the Web suits many information needs. However, the coarse level of document-level information ag- gregation does not fit the need of publishing atomic fact such as a date of birth, or a city of residence, so that it can be interpreted (or ”understood”) by some other computer program. On a typical biographical web page, such information will have to be manually harvested from the document. Although this is an easy task for human Web user, this becomes a daunting problem for a computer pro- gram. As a result, a Web browser can process a request phrased as “show me the personal Web page of Mr X” but can not give any definitive answer to “what is the date of birth of Mr X?”. It can even less merge the content of several web pages to find information scattered among them, or combine such information. It is based on this observation that the Word Wide Web Consortium (W3C) initiated the research on the Semantic Web in 2001 with the goal of establishing standards for the publication of structured information on the Web [1]. Using such standards, one can indicate that a particular date on a page is a birth-date, thereby providing any program parsing that page with the information it needs to give definitive answers. In the past few years more and more data-sources have
