Search engines and meta search engines are machine-compiled, while subject directories are human-compiled. Therefore its more reliable.
Meta search engines find the most appropriate results which makes it more credible. However, search engines displays all results in order of relevance.

Search engines returns large amount of hits, which user can have large variety of websites to choose from. However, it is not as reliable and credible as meta and directory searches because of the large amount of irrelevant hits.
Meta search engines compile the most appropriate results which let users have more relevant and credible websites. However, the results found are very few.
Search directories are human-compiled and therefore the hits are the most reliable compared to the other two. However, the links must be reviewed 1st, therefore there will be a larger lag and loading time.

Search directories would best meet my searching needs. The links found are human-compiled which makes my search much more credible and reliable. Moreover the links are reviewed before posting, therefore it will be most related to my search.

Week_4 of UIR

Practical 3
Here are 4 websites I've researched on.

Resource 1:
Purpose of resource : News
URL: http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html?inline=nyt-classifier#
Reasons :
The article is taken from New York Times, which is a news organization. It mentions more about the current events, such as how greenhouse gases had affected the atmosphere and contributed to global warming, and used diagrams to show retreating ice from the recent years.

Resource 2:
Purpose of resource : Personal
URL: http://ccr.aos.wisc.edu/news/0305046.pdf
Reasons :
Website provides articles with more personal opinions. Though articles mentions on the statistics and impacts of global warming, it does not focus too much on a particular topic but instead, article mentions on many different topics related to global warming. Tries to convey message by giving as many information as possible.

Resource 3:
Purpose of resource : Information
URL: http://en.wikipedia.org/wiki/Global_warming
Reasons :
Website provides many useful information such as statistics and negative impacts of Global Warming. It also contains many personal opinions. However, it doesn’t have a purpose such as to persuade readers to do something.

Resource 4:
Purpose of resource : Entertainment
URL: http://warmalglobing.com/index_files/latenight.htm
Reasons :
Although website does not have much information about Global Warming, it uses humor and jokes to let readers remember the importance and impact of the climatic change much easier and clearer.

Week_3 of UIR

Practical 2

HEY..
Here is some work i've done for week 3.

Personal:
URL - http://ccr.aos.wisc.edu/news/0305046.pdf
It’s a personal article from Ruddiman, William F. which mentions about mainly, ‘How did humans 1st alter the global climate’ and some of the ‘future implications and warnings’ towards global warming.

Organisational:
URL - http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html?inline=nyt-classifier/top/news/science/topics/globalwarming/index.html?inline=nyt-classifier#
Article is taken from New York Times. Article talks about how greenhouse gases affected and contributed to global warming. A diagram on retreating ice from the past years.

Some of the search facilities I used are the Yahoo Search Engine, Google Search Engine and Wikipedia.
Keywords i've used are ‘Global Warming’, ‘News articles’, ‘Journal’, ‘Impacts of global warming’, ‘Greenhouse Gases’, ‘Retreating glaciers’ etc.
The major differences between an organisational and personal website:
The organizational website is developed by traditional companies which provide articles with a higher reliability and credibility. It also provide information on current situations of global warming more than the personal website, which provide more of personal opinions.
