Ontologies have become a popular research topic in many communities. In fact, ontology is a main component of this research; therefore, the definition, structure and the main operations and applications of ontology are provided. Web content consists mainly of distributed hypertext and hypermedia, and is accessed via a combination of keyword based search and link navigation. Hence, the ontology can provide a common vocabulary, and a grammar for publishing data, and can supply a semantic description of data which can be used to preserve the ontologies and keep them ready for inference. This paper provides basic concepts of semantic web, and defines the structure and the main applications of ontology.

This paper describes two concepts on the Semantic Web and Ontology and points out the core role of Ontology in Semantic Web. Moreover, the writer gives a Double-Channel Helix Methodology and expounds its advantages at the structure and the task-flow.
Web to Semantic Web and Role of Ontology in its Development
This research is mainly about to discuss World Wide Web leading to the need of the proposition of a new concept i.e. Semantic Web. Concerning Semantic Web, the conducted research provides information for the implementation of semantic based web applications by providing the concept of structuring of data over the web to take advantage in extracting semantic based information. Going into the details, this paper presents Ontology as the main building block of Semantic Web of present time, its supporting technologies i.e. XML, RDF and OWL, and some existing limitations with respect to its use in real time web application development. Furthermore, before concluding the discussion some Semantic Web based applications are presented which are developed with the use of Ontology and providing lots of values in the implementation of semantic based applications by providing structured data over the web to take advantage in implementing efficient web based information retrieval search mechanisms.

With the advancement of science and the rise of information throughout the history of human civilization, the need for more effective storage and retrieval of this information has become increasingly significant. Therefore, through the scientific evolution, storage and retrieval tools were also evolved and shifted gradually from the keyword matching system toward meaning. The emergence of these tools, from ancient manual lists to the thematic headings in the nineteenth-century as well as thesauruses in the twentieth-century, illustrates such developments. Finally, with the arrival of computer sciences and digital environment specially web in the late twentieth century, the paradigm changed from the traditional storage and retrieval tools and based on keyword matching towards the tools of semantic relationship explanation, since with the emergence of the semantic web today, the use of ontologies has become crucial for the semantic and conceptual retrieval of information and knowledge on the Web. Among the conducted studies, there are only a few studies that have examined the history and foundations of ontology formation from the beginning and focused on its concept and application in the field of information. Accordingly, the current paper first deals with foundation of ontology formation, concept, and evolution from the beginning until now through a library research method and documentary research method, and then explains the place of ontologies in the field of information and retrieval of information especially semantic web.
An Investigation on Semantic Web
The World Academy of Research in Science and Engineering
The web is meant for human consumption rather than the machine consumption. At present scenario, everything on the web is machine readable, not machine understandable. The method for data handling in the traditional web (The Syntactic web) is tedious, time consuming, and also provides many unrelated information. The Syntactic web (Current Web) provides an interface for users to render HTML documents and retrieve linked documents with simple user interface commands. On the other hand, Semantic Web making the web more understandable by machines and provide accurate results. So Semantic Web is needed to express the information in a precise, machine interpretable form. This Web aims to convert the current web, which is dominated by unstructured and semi-structured documents into 'web of data'. In addition, Semantic web integrates the information in an intelligent way and providing semantic based access to the internet. Semantic is building an appropriate infrastructure for intelligent agents to run around the web performing complex action for their users extracting information from texts. Semantic web also provides automated information access based on Machineprocessable semantics of data and heuristics that use these metadata. This paper presents a comparative study of Syntactic and Semantic web technologies.
Role of Ontology in Semantic Web
2011
The present generation of computers is changing from single isolated devices to entry points into a worldwide network of information exchange. Therefore, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic Web, in which meaning is made explicit, allowing machines to process and integrate Web resources intelligently. The vision of the semantic Web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic Web crucially depends on the easy creation, integration and use of semantic data, which will depend on building an ontology. This paper states the role of ontology in supporting information exchange process, particulary with semantic Web.
Semantic web: golden era of information
International Journal of Engineering & Technology, 2018
Semantic Web is the extension of existing web that allows well defined expressions for the meaning of information which can be understood by computers and people both. In this paper we are doing study on semantic and is our review paper. Semantic web is a recommended development project by W3C (World Wide Web Consortium) which focuses on the enhancing of information search by keeping the facts in structured form using eXtensible Markup Language (XML) and marked in such a way that it can be understand by the system. To make the development of semantic web promising, new international standard is developed for exchanging of ontologies called OWL Web Ontology language. In XML we just provide tag of the model and store data in the hierarchy without its meaning, that's why the computer cannot be able to process the data but in Semantic Web user can provide with a definition so that the computer can better recognize its meaning and provide with the better displaying of information. A crux of semantic web is that it works on the definition of the ontologies. Ontologies are responsible for re-usability and sharing of information. Semantic Web provides with a shared language which has stored data in the non-ending linking of distinct databases which provides data related to the real world objects. RDF is a common language for semantic web and is responsible for the collection of data on web and assembles different database from diverse sources and SPARQL is there for linking of databases for unifying documents. Thus, semantic web is the well-structured data web that relates all the data that present on the web and understands them to provide the exact display requested by the end user.

Semantic web is a concept that enables better machine processing of information on the web, by structuring documents written for the web in such a way that they become understandable by machines. This can be used for creating more complex applications (intelligent browsers, more advanced web agents), etc. Semantic modeling languages like the Resource Description Framework (RDF) and topic maps employ XML syntax to achieve this objective. New tools exploit cross domain vocabularies to automatically extract and relate the meta information in a new context. Web Ontology languages like DAML+OIL extend RDF with richer modeling primitives and a provide a technological basis to enable the Semantic Web. The logic languages for Semantic Web are described (which build on the of RDF and ontology languages). They, together with digital signatures, enable a web of trust, which will have levels of trust for its resources and for the rights of access, and will enable generating proofs, for the actions and resources on the web.
Ontology Creation and Development Model
International Journal of Innovative Research in Computer and Communication Engineering, 2014
The continuing need for effective information retrieval, paved way for the inception of semantic web. It’s, unquestionably, as extension to the existing web which holds distributed information lacking any logical relationships amongst themselves. This information can be integrated and related to each other using ontologies. The paper intends to bridge this gap by providing a brief idea of ontology creation and how can it help in implementation of semantic web. The paper has threefold objective. Firstly the paper provides multiple definitions of ontology and their relation with in semantic web. Secondly the paper briefly provides a comparison of several ontology development tools justifies the use of a particular ontology tool. Lastly the paper proposes an ontology on data structures.
