Five criteria for evaluating Web pages

Evaluation of Web documents

• 1. Accuracy of Web Documents
  Who wrote the page and can you contact him or her?
  What is the purpose of the document and why was it produced?
  Is this person qualified to write this document

• 2. Authority of Web Documents
  Who published the document and is it separate from the "Webmaster?"
  Check the domain of the document, what institution publishes this document?
  Does the publisher list his or her qualifications?

• 3. Objectivity of Web Documents
  What goals/objectives does this page meet?
  How detailed is the information?
  What opinions (if any) are expressed by the author?

• 4. Currency of Web Documents
  When was it produced?
  When was it updated'
  How up-to-date are the links (if any)?

• 5. Coverage of the Web Documents
  Are the links (if any) evaluated and do they complement the documents' theme?
  Is it all images or a balance of text and images?
  Is the information presented cited correctly?

search engine

A Web search engine is a search engine designed to search for information on the World Wide Web. Information may consist of web pages, images, information and other types of files. Some search engines also mine data available in newsbooks, databases, or open directories. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically or are a mixture of algorithmic and human input.

The big 6 and information literacy?

What is information literacy?“To be information literate, a person must be able to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information.”

History of internet

A 1946 comic science-fiction story, A Logic Named Joe, by Murray Leinster laid out the Internet and many of its strengths and weaknesses. However, it took more than a decade before reality began to catch up with this vision.

The USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency, known as ARPA, in February 1958 to regain a technological lead.[2][3] ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment (SAGE) program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution.

Licklider moved from the Psycho-Acoustic Laboratory at Harvard University to MIT in 1950, after becoming interested in information technology. At MIT, he served on a committee that established Lincoln Laboratory and worked on the SAGE project. In 1957 he became a Vice President at BBN, where he bought the first production PDP-1 computer and conducted the first public demonstration of time-sharing.
