Essay On Internet And Search

For this assignment, I was allowed to improvise on a provided base code to develop a functioning web crawler. The web crawler needed to accept a starting URL and then develop a URL frontier queue of “out links” to be further explored. The crawler needed to track the number of URLs and stop adding them once the queue had reached 500 links. The crawler needed to also extract text and remove HTML tags and formatting. The assignment instructions offered using the BeautifulSoup module to achieve those goals, which I chose to do. Finally, the web crawler program needed to report metrics including the number of documents (web pages), the number of tokens extracted and processed, and the number of unique terms added to the term dictionary.

Google’s search engine allows users to input and submit data online. In return, the user would receive relevant search results. Behind the scenes upon the submission, web crawlers scan through billions of pages and link keywords from a user’s data to the publish data on the web. Their PageRank technology ranks these pages by the number and popularity of other sites that link to the page. This provides the user with accurate and popular results. Google search engines generated high revenues between advertising on its websites and selling its technology to other sites.

When many student go on and search on the web, the web can bring up false information which can lead the student to get the wrong ideas. Search engines are so simple, you just type in couple of words and it can bring thousands and millions of answers or information. Google for example has 3+ billion URL’s to search in, common words such as “a, an, in, to, the” are not searched since they are so common. The way that the engines work is once you type in the word or phrase the engines send out a software program known as spider, crawler or robot.

(King-Lup Liu, 2001) Given countless motors on the Internet, it is troublesome for a man to figure out which web search tools could serve his/her data needs. A typical arrangement is to build a metasearch motor on top of the web indexes. After accepting a client question, the metasearch motor sends it to those fundamental web indexes which are liable to give back the craved archives for the inquiry. The determination calculation utilized by a metasearch motor to figure out if a web index ought to be sent the inquiry ordinarily settles on the choice in light of the web search tool agent, which contains trademark data about the database of a web search tool. Be that as it may, a hidden web index may not will to give the required data to the metasearch motor. This paper demonstrates that the required data can be evaluated from an uncooperative web crawler with great exactness. Two bits of data which license precise web crawler determination are the quantity of reports filed by the web index and the greatest weight of every term. In this paper, we display systems for the estimation of these two bits of data.

Founded on September 4, 1998 Google quickly revolutionized the search engine and the Internet alike. Within two years of starting operations Google had become the largest single search engine in the world and began to dominate the market. As the World Wide Web (web) grew in popularity and became more and more a part of everyone’s daily life, Google too grew in popularity “because it could provide simple, fast, and relevant search results” (Deresky, 2011). The differentiating factor was Google’s “PageRank technology which displays results…by looking for keywords inside web pages, but also gauging the importance of a search result based on the number and popularity of other sites that linked to the page” (Deresky,

Welcome to the wonderful world of computer software engineering and web development, or as it more commonly known, coding. In this section, one will learn the programming languages used to develop a search engine.

Nevertheless, it has obtained gigantic awareness best in the up to date years [41-58, 60-64]. Targeted crawlers avoid the crawling method on a certain set of issues that characterize a narrow area of the online. A focused or a topical internet crawler makes an attempt to download websites critical to a suite of pre-outlined subject matters. Hyperlink context varieties and most important part of web headquartered understanding retrieval assignment. Topical crawlers follow the hyperlinked constitution of the online making use of the supply of understanding to direct themselves towards topically relevant pages. For deriving the proper expertise, they mine the contents of pages which are already fetched to prioritize the fetching of unvisited pages. Topical crawlers depend especially on contextual understanding. This is considering that topical crawlers need to predict the advantage of downloading unvisited pages based on the understanding derived from pages that have been downloaded. One of the vital fashioned predictors is the anchor textual content of the hyperlinks [59]. The area targeted search engines like google and yahoo use these targeted crawlers to download selected

Search engines cover the “publicly indexable web”. This is the part of the web easily

The surface web is open to anyone with internet access, and easily navigated due to search engines such as Google. These search engines use spiders, also known as crawlers, to collect the information from web sites and pages. The spiders crawl through the internet reading the text of the sites and pages, searching of hyperlinks, metatags (specially formatted keywords designed to be found and used by spiders) and code. Without these spiders, the search engines wouldn’t know what pages to display, nor the priority for the query. (HowStuffWorks)

Google Inc (Google) is the world leader in internet searches. By 2007 63% of internet searches were through Google, surpassing other search engines such as Yahoo and Microsoft MSN. Goggle has also developed web based tools such maps, toolbars, G-Mail and acquired the popular you Tube. After dominating the web search industry since its search engine was introduction in 1998, however, Google has attracted many competitors who try to provide millions of users worldwide with similar services. Many believe that there is room for competition and as a result, Yahoo!, Amazon.com and Microsoft MSN are fostering partnerships with smaller technology companies and making significant capital investments in order to

The purpose of this paper is to analyze the various ways in which search engines have been able to process

The World Wide Web is a very big topic to cover. It has changed over the years and is only getting bigger by the day as users, all over the world, are creating more and more content. With this ever evolving and expanding web it is paramount for individuals to know how to traverse through these vast amounts of content. In order for users to become better at traversing this ever expanding web they must first understand what tools they have at their disposal, such as search directories and search engines. These tools can be utilized to bring up information more effectively that is relevant to the information that the user is looking for. The most popular and effective search engine is google. Tylor Jones of Clapway stated that “google search is the best search engine because of their directory,

Search engines serve as an answering machine by providing, firstly, the results that are more relevant to the search query. Secondly, the ranking of results in order of popularity of the website that is serving the information. An assumption made by Search engines is that the more prevalent a website or web page is, the more useful the information it contains. A search engine will always use mathematical equations to determine the popularity and relevance of a web page or website. This algorithm will be used to separate the sort and later on rank in the order of its popularity and quality. The mathematical algorithms contain variety of variables often mentioned to as place factors.
