The World Wide Web was created by Tim Berners-Lee as a way for people to share information across networks. It was created as a decentralized bottom-up system and it is still run that way today. Users have the freedom to publish web pages as they wish and today there are over 60 trillion (and growing)! Web pages are sorted by properties and kept track of in a giant index.

Algorithms and Formulas Edit

One of the key components of the Web is hyperlinks. Hyperlinks enable a search engine to crawl (or search) the web. When a search term is entered into a search box the phrase is run through programs and algorithms to determine their relevance to pages on the Web. Spiders are software programs that begin by choosing a page and following the links on that page to the links that those pages point to, and so-on to build a web of information. The creator of the web can adjust their privacy settings to choose whether to allow a search engine to crawl their sites. Hyperlinks and web crawling can help determine how trustworthy a web page is.

Ways to search Edit

The standard way for a user to search is by typing a phrase into a search box on a search engine. It is also possible to search by voice. A search may even be done by image. This can be done by a web URL or by uploading your own personal pictures to the search bar. All of these raise privacy concerns to varying degrees. A search engine may take into account prior search records plus other factors such as geographic location when performing a search. This may put a user in a Filter Bubble.

Applications Edit

“Google Instant” shows search results without requiring a user to hit an “enter” button. Other search engines offer similar features. Search engines utilize autocomplete, predicting the intended search term by offering search suggestions. As the Semantic Web forms, searches will be customized to uses. There are also programs that understand the meaning of search terms. This is a major concern for tracking and privacy. Google uses PageRank to examine the links between pages to verify authenticity.

The search process Edit

There are over 200 questions that are analyzed when a search is done on the World Wide Web. Programs search for the phrase being contained in the title or URL of a webpage. Algorithms also look for synonyms contained within the same page. The authenticity is also taken into account using PageRank. After the user presses “search” a result page will appear in less than one second that ranks (what the search engine finds) is most relevant. As Web 3.0 begins to emerge, search engines will begin to produce Avatars for users and customize searches based on these assumptions. Users may be put in a Filter Bubble based on their tendencies.
