Some of the terminologies related to Web are as follows: URL: A URL or Uniform Resource Locator is termed as a Web address that represents a Web resource location on the computer network (Internet) and mechanisms for retrieving those resources.URI: A URI or Uniform Resource Identifier is something which is used to identify a resource and differentiate it from other resources by the use of the name of the resource or the location of the resource.Hypertext: Hypertext is those text or word on the webpage that are used to contain a link to a website.Hyperlink: A hyperlink is a reference to the data that the user follow by clicking or tapping on it, it is a word, phrase or image that can be clicked on to jump to a new document.

The Semantic Web (also known as “Linked Data”) is an extension of the Web via many standards by the World Wide Web Consortium (W3C). The standards boost the development of data formats and communication protocols on the Web. Among the various data formats in the Semantic Web, Resource Description Framework (RDF) is the most fundamental format and is commonly used. The rationale behind the RDF data model is that any arbitrary statement about resources within the web can be represented by a simple triple (i.e., subject, predicate, and object). Any levels of complexity in the descriptions of resources are possible using multiple lines of triples. The subject and object here can be considered as two resources. The predicate is the property of the subject and represents the relation between the subject and object. For example, a patient’s survival age, biological sex, and type of carcinoma can be described in the RDF format. Figure 11.4 shows the virtual representation of this ontology.

Creating a well-structured and descriptive information profile that follows a standard schema for each scientific resource is the key for indexing and linking resources over the Web. An information profile defines the metadata associated with a Web resource based on a metadata schema. The quality of information profiles varies and ranges from standard information that is used by large data centers to ad hoc labeling that is used by small research groups. Publishing information profiles for resources over the Web has become one of the focus areas for many research communities (e.g., [5–7]). However, only 5% of the scientific resources are stored using standard information schemas [8]. It is rare to find a scientific resource uploaded to the Web with descriptive information. Incomplete information about resources results in inconsistency in vocabularies pertaining to names of variables, units, spatial characterization, query formats, retrieval methods, and Web transfer protocols [9]. Lack of information makes automating the integration of scientific resources over the Web particularly challenging.
Instantiation of the multi-viewpoints ontology from a resource

The Semantic Web allows adding semantics to web content [1]. The ontology is considered as the cornerstone of the Semantic Web for knowledge sharing, information extraction, information integration, and many more [2]. The ontology allows offering a structural representation of the knowledge in a given domain. The knowledge in the ontology is represented via a hierarchical structure of concepts and a set of axioms. An axiom allows defining properties of concepts and defining relationships between concepts [3,4,5,6]. A web resource is any one of the files and documents that are available on the internet, like text documents, HTML pages, etc. We are interested in the text documents. A web resource, which belongs to a given domain, contains some instances of concepts. These concepts are represented in the ontology of this domain.
