Practical 4 and 5
Well, for this practical, we are still based on our research topic to do our research.. So let me tell you more about what I have done in this practical.
Well basically, I am supposed to choose the relevant keywords from my own research topic and then list the variations (synonyms) to the keywords that I have chosen.
So my topic is 'Discuss the impact of drugs abuse on youths'.
Keywords: Impact, Drugs Abuse, Youths
Variations (in respective order): Effect/Influence, NIL, Teenagers/Adolescence
After listing down the variations to the keywords, we had to now write out the search phrase with the keywords and variations. The search phrase made use of boolean operators like AND, OR and N/2 to narrow down the search results.
Search phrase for my topic will be:
(impact OR effect* OR influence) AND drugs abuse AND (youth* OR teen* OR adolescence)
Next, I had to use the search facilities to search for 3 resources using the search phrase. The search facilities are:
(1) Search Engines - Google
(2) Meta Search Engines - MetaCrawler
(3) Subject Directories - Yahoo Directory
While looking at the different search facilities and searching for my resources, I had to take note of the size of hits(total number of results), time taken and also evaluate and make a comparison on the effectiveness of each of them.
My Reflection
In today's practical, I learnt how to write search phrases using boolean operators like AND, N/2 and OR which i never knew before. I have also realised that using the '( )' will actually force the order of the operation as it will actually search the words that is inside the '( )' first. By using the search phrases to search for information, it will actually narrow the search results and looking for the relevant results would be much easier.
Next, I have also learnt what are the various types of Search facilities. They are Search Engine, Meta Search Engine and Subject Directory. After comparing each of the search engines, I realised that each of the search facilities has its own strengths and weaknesses. One of the Strengths of Meta Search Engine would be that users can get their information from the various search engines at one go.
Well, this lab really made my realise that there are not only the usual search engines like Google and Yahoo for us to search but lots more different search facilities avaliable for us. I have also learnt how to make use of the search phrases more effectively to narrow down our search results.
