Search Engines

“A search engine is a tool that enables users to locate information on the World Wide Web. Search engines use key words or phrases entered by users to find Web sites which contain the information sought” (www.getnetwise.org/glossary.php). It can be considered a modernized library card catalogue. Search engines are the primary use for the internet. It's important to understand that search engines do not search the internet itself. They rely on spiders or robots to search databases of information through the internet which the company hosting the search engine has developed (http://www.cln.org/searching_faqs.html). The most popular search engines are Google, Yahoo, Excite, HotBot, AltaVista, Lycos and LookSmart.

There a few essential concepts to understand about search engines. Since they do not search the internet, one might be curious to know how search engines obtain their results for users. When a publisher creates a document that he wants posted on the web, he can register it with different search engines. This is how users find his webpage in their results. The second way that documents are registered to search engines is if the company finds it as part of its research routines. All search engines are intended to accomplish the same duty, although each engine goes about this duty in various ways. “Components that affect the results consist of size of the database, frequency of updating, and the search capabilities. Search engines also digress in their search speed, way in which they arrange their results, and measure of assistance they grant” (http://www.ouc.bc.ca/libr/connect96/search.htm). There is also what we call a “meta” search engine. These search engines allow the user to search multiple databases...

    Launching in 1997, Google has grown as a superpower around the world in only 17 years of business (Bullas). The simple, quick, and instant responses to just about anything are incredible. But what goes on behind the scenes in Google? According to Gabriel Weinberg, the Software Producer, and current CEO of DuckDuckGo search engine, “Google is increasingly tailoring your searches based on your search history”. This is known as Individual profiling. The process of individual data profiling is when Google gathers information about you, whether it is the content of your gmail, your Google Plus, or even your searches,and organizes it into your own user data information, your user data is then used in various different ways. Profiling raises a few red flags in respect to the user. First, you must realize that anything you search can be tracked by any Google worker, or used against you in court (Weinberg). And second, your history gives search engines the information needed to direct you toward higher hotel prices etc. for the convenience of advertising companies (Mattioli).

    Jane Austen's novel Emma (1815) and Amy Heckerling's film Clueless (1995) have, to a large extent, maintained similar values regarding gender and class; although due to contextual differences, their manifestations have been altered to a certain degree. Both texts inform their respective audiences of the dynamic nature of the class system, the importance of social class in relationships, and the patriarchy prominent in society. Austen and Heckerling demonstrate that attitudes and values can remain the same, despite the contextual changes.

  • Elephant Poaching Research Paper

    283 Words  | 1 Pages

    Elephants have been threatened by poachers! Do you know what poachers are? Poachers are people that hunt and kill animals/Elephants for Ivory. Ivory is an elephant’s tusk. Even a walrus tusk. Ivory could also be known as teeth. Even though it was illegal, poachers were still hunting for elephants. Killing the elephants helped the poachers, because they could use ivory to trade for food. The food that they traded would usually help the poacher’s family survive. Most people would poach if they were poor. And that’s what it was like.

    The World Wildlife Fund is an organization that helps to protect and preserve the endangered Sumatran elephants. One way they are helping is by sending ‘rangers’ to Indonesia to set up fences to keep the elephants out of the harm of villages and back into their habitats. In 2004, they established the Elephant Flying Squad, which is “made up of rangers, noise and light-making devices, a truck, and four trained elephants that would drive wild elephants back into the forests if they threatened to enter villages” (Elephant). In addition to physically moving the elephants away from villages and away from human contact, the WWF also did some research on the Sumatran elephants to find a way to make sure humans and elephants can coexist (Elephant).

    The Internet has created a generation of the most efficient multi-taskers ever born. Many people will have at least four tabs open as a time (Google, Facebook, Youtube, Pandora, Wikipedia, Gmail, etc.). People are constantly jumping from one web page to the next, clicking on links and opening new tabs and browsers. The method through which knowledge is gained has transitioned from deep reading to fast skimming. Every time a web page is opened the viewer is bombarded with information, almost every page has advertisements or links to additional information lining its sides. The Internet has made mountains of information available to almost anyone. It is fast and easy to find information and facts. Essentially the Internet has become the fast food of knowledge. It is convenient but it skips the element of effort.

  • Compare And Contrast Science And Religion

    1013 Words  | 3 Pages

    Barbour writes, “Changing cultural presuppositions also affect perception of what is significant in the social world.” (pg.137) It becomes so simple to say that science and religion are completely different, and while they may share differences I think that it is unfair to say that science and religion are separate from one another. If careful consideration is taken you can take notice that may issues that arise in the Bible such as consuming red meat, banning pork, discarding fat within meat are all backup by scientific facts. Issues that arise within science such as Einstein’s seven invisible dimension that are left unexplained, however many religion believe in the seven levels of “the heavens”, “the invisible”, “the afterlife”, and “the everlasting”. Issues such as the ones mentioned above are ones that connect science and religion on such as deeper level than many care to reveal. I think that it is fair to say that both science and religion have become so reluctant in their own stubborn, self-centered ideologies. Both science and religion have become so consumed in their own ideologies, and understandings that neither allows attention from the others research of teachings. I whole heartedly believe that if science and religion were used to approve one another rather than disprove one another there could be more of a mutual balance and connection between the two. There are numerous similarities in the processes that are taken when achieving new understandings, and knowledge. Also if we allowed ourselves to be honest if science and religion worked together rather than against each other there could be so many new discoveries that could be made, and so many debates that could be put to rest. Like I mentioned before but I think it is important, it either side stopped trying to disprove one another and rather

  • The Relationship Between Science and Religion

    1381 Words  | 3 Pages

    First off, it is important to realize that religion and science have to be related in some way, even if it is not the way I mentioned before. If religion and science were completely incompatible, as many people argue, then all combinations between them would be logically excluded. That would mean that no one would be able to take a religious approach to a scientific experiment or vice versa. Not only does that occur, but it occurs rather commonly. Scientists often describe their experiments and writings in religious terms, just as religious believers support combinations of belief and doubt that are “far more reminiscent of what we would generally call a scientific approach to hypotheses and uncertainty.” That just proves that even though they are not the same, religion and science have to be related somehow.
