Firstly, my first assignment topic is
'Discuss the impact of terrorism on world economy.' In this particular practical, i need to search through three different search facilities to compare and evaluate on the search effectiveness of the search engines.
The three search facilities that I have used are
GOOGLE (search engine),
Ixquick(Meta search engine) and
Yahoo! Directory (Subject Directory). I have typed in the same keywords for all searcj facilities;
'terrorism impact on world economy.'For the search engine, the hit size was very large and google displayed a wide range of impacts that terrorism has caused. In other words, i could say that this search engine was very efficient in displaying large sume of results in a short perioid of time. Most of the results are relevant to what I am finding and the format and arrangements are all very clear.
Moving on to the meta search engine, its search results are very accurate and easily comprehend. One special feature about this meta search engine is that it will display a star near the results if any search engine chooses it as one of the ten best results. Similar to search engine, this meta search engine also return large size of results that are relevant to my keywords.
Last but not least, the subject directory. For this subject directory, I think that the hit size is not as big as the other search facilities and some of the results are irrelevant.
The similiarities between these three search facilities are that they search through results from the keywords I have entered. The differences are the seach capabilities as in the relevancy of the results and also the hit size.
I think that Google is the most excellent among all the three search facilities. This is because, unlike yahoo! directory that return quite irrelevant results, Google return very relevant results. In addition, google also rank their results according to relevancy. The hit size is also very big compared to the rest.
All in all, this activity has helped me have a better view of the different search facilities available. With thie activity also, I found out the most efficient search facility that can be used for all my researches.
