Back in the modern days, the Internet is a whole collection of a media composed of reproductions. It is a virtual space, which has no original and lacks even a master copy. We, human as the user, offer to put the information inside the space. However web pages do not exist until they are uploaded onto the Internet by the author, and “reproduced” on our computer. Nowadays we can even create our own webpage on the cloud. To look for an original on the Internet is such a hard job since there are somehow no real material base to

The first point to check is authority which mainly looks at the author of the page. When evaluating authority, you must be able to verify the author’s credential as well as veryify if the page has copyright credit (LIBRARY). Authority also consists of being able to contact either the author or editor by email, phone or main (LIBRARY). Next, the website’s facts need to be verifiable which is accuracy (LIBRAY). This process is looking to see if there is an editor of the site who verifies the information to ensure that it is accurate (LIBRAY). According to GCU Library Tutorial (n.d.), researchers should also pay attention to the domain of the website to see if they are an organization, commercial or educational site. The next step is to see if the site has objectivity by trying to define what are the goals of the site (LIBRARY). The Tutorial (n.d.) suggests that the researcher makes observations in regards to the whether o...

The Center for Academic Integrity based at Duke University studies issues of academic integrity including trends in cheating and plagiarism across the United States. Its studies show that Internet plagiarism is a widespread problem among high school and college students. There are several types of Internet plagiarism.

Data mining has many benefits. Stores are able to stock merchandise that better reflects what customers want. When Victoria’s Secret started tracking user purchases they noticed that customers in Miami bought much more white lingerie than customers in other areas. As a result they began stocking more white products instead of uniformly stocking all stores benefiting both the store and the customer[i]. Another benefit is that it allows companies to consolidate data from many different sources so that more time can be spent analyzing data than finding it in the first place. This is useful for companies that have multiple financial systems and spend a lot of time trying to combine data into a more useful format rather than doing the actual analysis of the data. A more dramatic example is that some say that 9/11 could have been prevented if the FBI had better data mining tools to share and combine information from different offices[ii]. In addition to crime prevention and financial analysis the medical research community can use these techniques in medical research to identify trends and causes of disease.
