Handbook of Semantic Web Technologies - Semantic Web search engines
2011Co-Authors: Mathieu D'aquin, Enrico MottaAbstract:The last couple of years have seen an increasing growth in the amount of Semantic Web data made available, and exploitable, on the Web. Compared to the Web, one unique feature of the Semantic Web is its friendly interface with software programs. In order to better serve human users with software programs, supporting infrastructures for finding and selecting the distributed online Semantic Web data are needed. A number of Semantic Web search engines have emerged recently. These systems are based on different design principles and provide different levels of support for users and/or applications. In this chapter, a survey of these Semantic Web search engines is presented, together with the detailed description of the design of two prominent systems: Swoogle and Watson. The way these systems are used to enable domain applications and support cutting-edge research on Semantic Web technologies is also discussed. In particular, this chapter includes examples of a new generation of Semantic applications that, thanks to Semantic Web search engines, exploit online knowledge at runtime, without the need for laborious acquisition in specific domains. In addition, through collecting large amounts of Semantic content online, Semantic Web search engines such as Watson and Swoogle allow researchers to better understand how knowledge is formally published online and how Semantic Web technologies are used. In other terms, by mining the collected Semantic documents, it becomes possible to get an overview and explore the Semantic Web landscape today. The first section below (Sect. 16.1) presents a general overview of the area, including the main challenges, related systems, as well as an abstract specification of what is called Semantic Web search engines. It also includes a detailed overview of the two systems more specifically considered as case studies, Swoogle (Sect. 16.1.4) and Watson (Sect. 16.1.5). Section 16.2 shows how these systems are currently being used and applied, both as development platforms to make possible the realization of applications exploiting Semantic Web content (Sect. 16.2.1), and as research platforms, allowing one to better understand the content of the Semantic Web, how knowledge is published online and how it is structured. Finally, Sect. 16.3 briefly introduces other resources to be considered in the area of Semantic Web search engines, and Sect. 16.4 concludes the chapter.

Next generation Semantic Web applications
1st Asian Semantic Web Conference, 2006Co-Authors: Enrico Motta, Marta SabouAbstract:In this short paper, we examine current Semantic Web application and we highlight what we see as a shift away from first generation Semantic Web applications, towards a new generation of applications, designed to exploit the large amounts of heterogeneous Semantic markup, which are increasingly becoming available. Our analysis aims both to highlight the main features that can be used to compare and contrast current Semantic Web applications, as well as providing an initial blueprint for characterizing the nature of Semantic Web applications. Indeed, our ultimate goal is to specify a number of criteria, which Semantic Web applications ought to satisfy, if we want to move away from conventional Semantic systems and develop a new generation of Semantic Web applications, which can succeed in applying Semantic technology to the challenging context provided by the World-Wide-Web.

The Semantic Web – ISWC 2005 - The Semantic Web – ISWC 2005
Lecture Notes in Computer Science, 2005Co-Authors: Yolanda Gil, Enrico Motta, V. Richard Benjamins, Mark A. MusenAbstract: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 Bankthat 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 restructure 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.The original publication is available at www.springerlink.com http://dx.doi.org/10.1007/11574620_3
