Classification of web pages greatly helps in making the search engines more efficient by providing the relevant results to the user’s queries. In most of the prevailing algorithms available in literature, the classification/ categorization solely depends on the features extracted from the text content of the web pages. But as the most of the web pages nowadays are predominately filled with imag...

The importance of a Web page is an inherently subjective matter which depends on the readers interests knowledge and attitudes But there is still much that can be said objectively about the relative importance of Web pages This paper describes PageRank a method for rating Web pages objectively and mechanically e ectively measuring the human interest and attention devoted to them We compare Page...

Web pages are highly dynamic and it’s difficult to retrieve the relevant web pages in top 10 search results. This is based on some ranking mechanism incorporated retrieval system. The Retrieval system is designed for ranking the relevant web pages for user query. Usually, the retrieval system considers many techniques for ranking such as link based, connectivity based and keyword based techniqu...

A focused crawler may be described as a crawler which returns relevant web pages on a given topic in traversing the web. Web Crawlers are one of the most crucial part of the Search Engines to collect pages from the Web. The requirement of a web crawler that downloads most relevant web pages from such a large web is still a major challenge in the field of Information Retrieval Systems. Most Web ...

Deep Web contents are accessed by queries submitted to Web databases and the returned data records are enwrapped in dynamically generated Web pages (they will be called deep Web pages in this paper). Extracting structured data from deep Web pages is a challenging problem due to the underlying intricate structures of such pages. Until now, a large number of techniques have been proposed to addre...

The cyber attacks using web sites for a personal information sale or break down the infrastructures are increasing. To prevent cyber attacks, virtual computer systems are hired and dynamic malicious web site analysis systems are used. However the dynamic analysis systems have to setting up a targeted environment and have a threat of real attack. Unlikely the dynamic analysis system, a static ma...

Web crawling is used to collect the web pages which will be indexed by a search engine. The search engine uses these crawled and indexed pages to answer users’ queries. Since the volume of web pages is very high and it increases continuously, search engines can index a limited number of web pages. Therefore, in recent years, the focused crawler algorithms have been introduced which act selectiv...

One of the characteristic features of the World Wide Web is that it allows anyone to publish web pages, and to link their pages to any other web pages. The emergent result of this process is that communities arise that are focused around subjects of common interest. Identifying these communities can be challenging, due to the large size of the web graph and the unstructured nature of publishing...

Web is a system of interlinked hypertext documents accessed via Internet. Internet is a global system of interconnected computer networks that serve billions of users worldwide. The huge amount of documents on the web is challenging for web search engines. Web contains multiple copies of the same content or same web page. Many of these pages on the Web are duplicates and near duplicates of othe...
