Artificial Intelligence Techniques A22589The potential applications of the semantic web as a possible direction to solve the problem ofinformation extraction from web pagesThe Semantic Web is an extension of the Web through standards by the World Wide WebConsortium (W3C). The standards advance basic information arrangements and trade protocolson the Web, most on a very basic level the Resource Description Framework (RDF).Accordingto the W3C, "The Semantic Web provides a typical structure that permits information to beshared and reused crosswise over application, enterprise, and community boundaries". The termwas coined by Tim Berners-Lee for a web of information that can be prepared by machines.While its critics have questioned its feasibility, advocates contend that applications in industry,biology and human sciences research have effectively demonstrated the validity of the originalidea. A term used to describe Web-based applications that incorporates principles ortechnologies of the W3C Semantic Web, for example, RDF, OWL and other metadata standards.The vast majority of today's web substance is designed for human consumption, which makes itdifficult for software tools to get to them readily. Evenweb content that is automaticallyproduced from back-end databases is normally exhibited without the original auxiliaryinformation. In this paper, we introduce an automated information extraction algorithm that canremove the significant attribute-esteem pairs from item descriptions crosswise over differentsites. A notion, called basic semantic entropy, is used to find the information of interest on webpages, which measures the density of event of important information on the DOM treerepresentation of web pages. Our methodology is less work intensive and insensitive to changesin web-page position. Experimental results on a substantial number of genuine web pagecollections are encouraging and confirm the feasibility of the methodology, which has beeneffectively applied to identify false medication advertisements on the web because of its capacityin associating the attributes of records with their respective qualities.In addition to the classic "Web of archives" W3C is helping to build an innovation stack tobolster a "Web of information," the kind of information you find in databases. The ultimateobjective of the Web of information is to empower PCs to accomplish more useful work and tocreate systems that can bolster trusted interactions over the system. The expression "SemanticWeb" alludes to W3C's vision of the Web of linked information. Semantic Web technologiesempower individuals to make information stores on the Web, build vocabularies, and write rulesfor handling information. Linked information are empowered by technologies, for example,RDF, SPARQL, OWL, and SKOS.The Semantic Web is a Web of information — of dates and titles and part numbers and chemicalproperties and whatever other information one might conceive of. RDF provides the foundation
for publishing and linking your information. Various technologies permit you to embedinformation in records (RDFa, GRDDL) or uncover what you have in SQL databases, or make itavailable as RDF files.The word semantic itself implies meaning or understanding. In that capacity, the essentialdifference between Semantic Web technologies and other technologies identified withinformation, (for example, relational databases or the World Wide Web itself) is that theSemantic Web is worried with the meaning and not the structure of information.The Semantic Web is an idea of World Wide Web inventor Tim Berners-Lee that the Web all inall can be made more intelligent and maybe even intuitive about how to serve a user's needs.Berners-Lee watches that in spite of the fact that internet searchers index a significant part of theWeb's substance, they have little ability to choose the pages that a user truly needs or needs. Heanticipates various courses in which engineers and creators, singly or in collaborations, can useself-descriptions and other techniques so that setting understanding projects can selectively findwhat users need.This crucial difference causes a totally different attitude toward how storing, querying, anddisplaying information might be drawn nearer. A few applications, for example, those that alludeto a lot of information from a wide range of sources, benefit colossally from this component.Others, for example, the storage of high volumes of highly organized transactional information,don't.Semantic web permitted the user to find, share and combine the information to exchange itstarting with one place then onto the next easily. It permits the working of current web andmakes it more secure and usable by showing the information. The users are permitted to use theWeb for carrying out the undertakings of finding the folder or categories and it just makes itsimple. Semantic web provides the instructions for the machine to execute the assignments byproviding the interpreter that can interpret it. machines can perform the undertaking provided bythe Semantic Web and it involves finding, combining and acting on the information that isavailable on the web.Semantic Web provides system on which the applications can be made and created using thetools. It permits the information to be shared and reused between numerous applications and
other enterprise level applications. W3C also known as World Web Consortium uses theimprovement libraries for the Semantic web standards. The semantic web describes the web ofinformation that can be directly or indirectly gets executed on the client machine. This usesdisambiguates principle that doesn't permit the ambiguous solution to be provided with thesystem.Semantic HTML provides the traditional methodologies to work and markup the code accordingto the guidelines. It doesn't specify the format details in which the HTML should be exhibited orwritten.Semantic HTML uses the old tags like <em> that denotes emphasis rather than <i> tag that usedto denote italics. Format details are web browser dependent and it is placed according to thecombination of Cascading style sheets. The semantic of the objects are also not described by theuse of items and by using their sales and price detailHTML is a tool that permits the rendering of the web pages and creation of it using the editor.The web page can be made with simple to use tags, browser compatible code and list of items.Simple documentation can be made using the tools that is being provided by HTML. Images canbe displayed in variety of ways and content can be made drifted using the special tags defined inHTML version. The pieces of information can be combined together to describe the items andother items on different web pages.Metadata tags provide the keywords that are used for the search engine to make the website orthe web page search engine friendly. It is a method to categorize the content of the web pages onthe search engine so that it can be easily found by the browsers.Metadata tags are represented as:<meta name="keywords" content="computing, computer, comp" /><meta name="description" content="Hello world" /><meta name="author" content="Rohit Kumar" />Metadata tags provide great description in the tags and permit the substance to be displayed forbetter execution of the web pages.
