Blog Reflection~!

Let me share what i have learned when I am using different search facilities to search for resources related to my topic: The three search facilities, Google, Metacrawler and Yahoo Directory are equally useful as a search engine. The similarities of the three search engines are that they use a short period to search the results. It is fast. The users can search with the keyword. All of them have a sponsored listing for each result and give the number of results to users. These three search engines have advanced search, it helps the users to search with more convenience and accuracy.


However, they also have some differences. For my topic (impact of online gaming on youth), Google can find 2,010,000 results in 0.23 seconds; Yahoo directory use 0.36 second find about 494 results for the topic; Metacrawler only find 52 results for the topic and do not show the period of searching time. From these data, we can find that Google has a wider range of search results and short searching period with regard to my topic, it gives me more choices; Yahoo and Metacrawler have minimized search results. I only choose Google and Metacrawler for my search engine, because I can only find useful results for my topic in these search engines.

There are other differences of the three-search engine. Yahoo directory has related directory categories, but Google and Meta search engine does not. Users can select the categories to know more information about the topic. However, Google and Meta search engine give different types of searches, such as web, video, but yahoo directory only can search in the directory type. Meta search engine gives the users preferences for searching, and gives the results from all the other search engines. Google and Meta search engine give the users similar results of topic, it can help the user search more information about the topic.

I am very like to collaborating on wiki with my classmates who share similar research topic as me. Because I find when we sharing with each other, we can find more information about my topic and I can learn different opinions from different views about my topic.It is a very good way to learn more and make my presentation better.
