Tutorial
Task 1
For this task to have been completed, I had to visit http://www.monash.com/spidap.html website in order to work on search engines and directories. I had to find out four strategies that will help me present a good search engine in my learning log. Below are the four strategies:-
1) It’s essential to purify your search; this means you have to break down your search topic into something more detailed. This can be done by using Boolean operators. These operators are reasonable terms such as “and”, “or”, “not”.
2) Generally when we search something on the website, we get heaps load of page results. However the results are positioned according to how closely they relate to the topic. In my opinion, I have come across that most search engines do not provide relevant information on the topic I work on. Therefore in order to get the best results, I might have to change the keywords I use for my investigation.
3) Search engines intended to choose keywords, when you are searching for a particular topic. Examples of common keywords include: “or”, “and”, “is”, “a” etc.There is also the concept-based searching, this occurs when the system attempts to decide what you exactly mean.
4) There is also the concept-based searching, this occurs when the system attempts to decide what you exactly mean.Task 2For the second task, I had to complete this online Internet quiz on the website http://www.siteseen.co.uk/questions/historytrivia/. I knew some of the answers, though I had to research the other ones in order to get the correct answer.
WEEK FIVE READINGS
Reading OneRobert Harris: "Web Search Strategies" http://www.virtualsalt.com/howlook.htmThe content on this website is quite similar to the other website I have visited in my earlier workshop, "Bare Bones Lesson 7: Basic Search Tips". In this web page it also contains information such as:· Using Boolean operators· keyword/phrase search
However this has few more extra tips compare to the ""Bare Bones Lesson 7: Basic Search tips"website .
This includes:
1) Using several search tools
2) Guessing a location
3) Read the search tips of help information at each search engine
Reading Two
" The History of the Internet (Chapter 4 - Search Engines)" http://www.let.leidenuniv.nl/history/ivh/chap4.htm
The website is based on the history of the Internet. Its set up very well, as it's divided into sub topics, so its easy for the viewer to view a topic quicker. The site states the writer, Richard T. Griffiths who is known to be from the Leiden University. It establishes that the writer, Richard T. Griffiths has a very good knowledge, because the information seems to be very true. The page has been last renewed on the 11th of October, in the year 2002. This is not that old, therefore the information can still be used. I would personally like to use this web site, as it provides great information on the history of Internet and about different types of search engines, databases and library catalogues.
Reading Three
The site contains no author/writer. This website is quite different compare to other ones. I think you can start up your own website if you desire to. You can send them several keyword phrases that you might want to search on a search engine. However there are other things that are available on this website.
These include:-
* Link popularity
* Measuring your Progress
* Link popularity
* Measuring your Progress
* Setting your benchmark
From my point of view, I would not recommend this website to anyone, this is because i do not feel as it provides any great help.
