[...]... FROM THE SEMANTIC WEB TO SEMANTIC WEB SERVICES Once we have understood the core building blocks of the Semantic Web, and after we have experienced the value added by the Semantic Web vision, the next logical question to ask would be what the Semantic Web can do for Web services Currently, this is one of the most active research areas, and it is true that adding semantics to Web services will change the. .. more on the Web The answer to this question intuitively introduces the need for adding semantics to the Web, which leads to the concept of the Semantic Web Given the relationship between metadata and the Semantic Web, a comprehensive introduction to metadata is also included in this chapter Chapter 2: Search Engine in Both Traditional and Semantic Web Environments The goal of this chapter is to further... is the potential value that can be added by the vision of the Semantic Web Chapter 1: From Traditional Web to Semantic Web This chapter presents a careful introduction to the concept of the Semantic Web We start the discussion by summarizing the structure of the current Web and the main activities conducted on it; we then move on to the key question about what is it in the traditional Web that stops... experiencing with the Web, and more importantly, the reasons for these difficulties At this point, we will introduce the concept of the Semantic Web and, hopefully, this concept will be less confusing to you Furthermore, based on this basic understanding of the Semantic Web, we will “add” some semantics to the Web, and reexamine the topic of search engine: How does the added semantics change the way a search... one step further by pointing out one of the most fundamental aspects of the Semantic Web: the connection between two worlds — the semantic world and the Web world — has to be built in order to turn the vision of the Semantic Web into reality More specifically, this connection is built by semantically marking up Web pages This is where the idea of “adding semantics to Web is translated into action Examples... this chapter, you should be able to gain more insights into the benefits offered by the Semantic Web vision PART 2: THE NUTS AND BOLTS OF SEMANTIC WEB TECHNOLOGY After establishing a good understanding of the Semantic Web concept, we use four chapters to present the technical details of the Semantic Web and its core components Chapter 3: The Building Block of the Semantic Web: RDF This chapter presents... discussed first to make you understand the importance of RDFS and how it fits into the vision of the Semantic Web The language features and constructs of RDFS are then presented in great detail As RDFS is mainly used to construct ontology, the concepts of taxonomy and ontology are formally introduced in this chapter To understand what ontology is and to make RDFS language features and constructs easier to follow,... ontologies, and how they are used to make the Web a more interesting and useful information resource Many examples are included in this chapter, such as creating your own FOAF document and publishing it on the Web to get into the “circle of friends.” The goal of discussing FOAF is to let you see a real-world example of the Semantic Web and to give you the flavor of using Semantic Web technologies to. .. information for the computers to present them, not to understand them If the documents on the Web also contained information that could be used to guide the computers to understand them, all three main activities could be conducted in a much more elegant and efficient way The question now is whether it is still possible to reconstruct the Web by adding some information into the documents stored on the Internet... you understand the points in the foregoing long definition After establishing the initial concept of the Semantic Web, most books and articles immediately move on to the presentation of the different technical components that underlie the Semantic Web For a mind that is new to the concept, however, getting into these nuts and bolts without first seeing how these components fit together to make the vision . in the traditional Web that stops us from doing more on the Web. The answer to this question intuitively introduces the need for adding semantics to the Web, which leads to the concept of the Semantic. on automatic service discovery. Chapter 11: From Web Services to Semantic Web Services. The goal of this chapter is to introduce the concept of Semantic Web services: what they are and why they. publishing it on the Web to get into the “circle of friends.” The goal of discussing FOAF is to let you see a real-world example of the Semantic Web and to give you the flavor of using Semantic Web technologies
