Reflection on lessons learnt from Practical 6.


I was given a task to conduct an evaluation on the effectiveness of using the Invisible Web which is also known as the databases. I was to make a fair comparison between the search engine and the database to research for my research topic, Causes and Effects of Internet and Computer Addiction". After comparing, I am to state on whether which search tools serves me best by stating the reason why and to produce it clearly on my reflection. 
------------------------------------------------------------------------------------------
Conduct a search using Invisible Web (Databases):
Firstly, I have to select on two from a list of different categories of databases that are suitable for my research topic. The following categories are: 


  • Newspapers (eg Factiva, Newslink, Business Times, Straits Times)
  • Journals & Magazine Articles (eg EBSCOhost, PsycARTICLES, ScienceDirect)
  • Reports & Statistics (eg Global Issues in Context, Worth Global Style Netwrk)
  • Specialist Resources (eg Air Transport Intelligence, LawNet, Naxos Music Lib)
After selecting on the two relevant databases which I felt that is suitable for my research topic, I would have to then conduct a search using the keywords related to my research topic and briefly describe the search results. 

To make the search results on the database fair, I chose "(Causes OR root of problem) AND (effects OR results OR consequences OR outcome) AND (addiction OR obsession) AND (youth OR adolescent OR teenagers) AND Internet AND computer" as my keywords in the search query. 

Database 1. Describe the search results:
The first database that I have chosen is LexisNexis. LexisNexis is able to provide me with a few articles that are of relevance to my research topic. Although the articles provided has not much information, but I was still able to obtain sufficient information as reference for my research topic.

Database 2. Describe the search results:
The second database that I have chosen is ScienceDirect. ScienceDirect was able to provide me with articles that are of relevance to my research topic but however the information provided in each articles were quite limited. To be able to accessed into the articles fully I was to make an account first which I felt that was unnecessary. 
------------------------------------------------------------------------------------------
Searching the Invisible Web, TP's Databases:
After conducting a search and completing the brief description on the search results on the two relevant databases that I have chosen, I am required now to search results using the "eBook" database from Temasek Polytechnic's (TP's) databases. After searching results using the "eBooks" database, I am to briefly describe the search results obtained from it. 

Describe your search results using "eBooks" database:
TP's "eBooks" database does not provide me with much information that I need for my research topic. The results were narrowed down and were limited as I specify my requirements in the search query, thus I felt it difficult in searching information among the thousands over articles when using simplified keywords in the search query. 
Here is a snap shot of the options that I have to choose when I specify my keywords: 


I was only allow to choose simplified words for my search in results for my search topic which caused a large amount of time consumed in sourcing for the information that I need. 

------------------------------------------------------------------------------------------

After conducting a search and completed the evaluation on the search results I've obtained from the databases, I am now to do a comparison and analysis to state which search tools have serve me best and the reason why I have make this decision. 

Comparison and Analysis:
  1. Do you think it is more effective to search the invisible web (databases) than using search engines? Why?
    I, myself, don't think it is more effective to search using the invisible web (databases) than using search engine. In comparison with the amount of information that I was able to obtain through the databases and search engine by using the same keywords in the search query, I felt that search engine had provided me with more information of relevance to my research topic. More than I need for reference.  In comparison with the amount of time used in searching for relevant results, search engine had save me more time than to databases in terms of issues met about the keywords used in the search query.
  2. Name one database which you will use for your research topic. Why? 
    LexisNexis. LexisNexis is the only database that has provided me with relevant information that I need for my research topic. Although LexisNexis only provided me a few relevant articles when compared to articles that I had obtained from the search engine, however, LexisNexis serves me better compared to the other databases in terms of amount of time that I used to retrieve the information that I need for reference on my research topic.
