  • Essay / Components of the Semantic Web

    The Semantic Web is a term coined by Sir Timothy Berners-Lee that refers to a set of standards for easily sharing and reusing data between applications (Wikipedia nd). It is an extension of the World Wide Web that gives information a well-defined meaning and allows people and computers to work cooperatively (Berners Lee et al., 2001). The Semantic Web promotes the use of standardized formats and protocols to create and exchange data between multiple programs. (Antoniou et al 2008) considered the Semantic Web as an approach that would allow web content to be represented in a form that is easily machine-processable. Representing content in this format allows computers to process, store, manage and retrieve information based on its meaning, importance and logical relationships (Ontotext nd). This allows content stored and accessed on the web to be presented in a format that is easy for humans to read. process and understand. The vision of the semantic web is to enable the efficient sharing of data that can be processed and consumed by tools manually or automatically (Saraf, 2008). The Semantic Web consists of key components which constitute the building blocks for effective functioning of the system namely SPARQL, RDF, URI, UNICODE, XML which will be explained in detail.

The latest version of UNICODE includes more than 136,000 characters from 139 contemporary and historical scripts. Uniform Resource Identifier (URI): This is a character string used to identify and locate resources. They form the basis for searching web pages on the Internet.Resource Description Framework (RDF): RDF is a general model for exchanging data on the Web. While Extensible Markup Language (XML) allows users to add subjective structure to their documents but does not define what the structure means, RDF aims to define what those structures mean. This makes web data more versatile and can be compared to what catalog cards do for library books, making data retrieval faster and more accurate (Bosak et al, 1999). The standard determines how information is described or modeled on the Web (Hayes, 2004). RDF consists of three key concepts which are considered the triple RDF. Resources: This can refer to a specific item or resource being discussed. This could be something like a specific laptopProperties: This describes the relationship between resources. This could be that the laptop "is" Windows. Statements: This provides the value of the resources. An example is that the laptop has a screen size of 14 inches. RDF Schema (RDFS): This is a type of basic modeling language that describes different classes of properties that can apply to different types of resources in the basic RDF model. It gives a simple structure to derive different types of resources. Simple Protocol and RDF Query Language (SPARQL): Pronounced like "sparkle", is a query language for RDF. It is designed to specifically query data across multiple platforms and to retrieve and process data stored in RDF (Ontotext sd) format. Extensible Markup Language (XML): This term can’
