Week Five, 28th March 2008: Using Search Engines

Lecture
this week’s lecture was all about search tools. Search tools fall into two main categories; search engines and directories.

What is a search engine?A search engine is a web-based application on the internet, creating indices of websites, usually from the textural information contained on them. Sites are usually indexed according to keywords.

Some examples of search engines are; google.com, yahoo.com, altavista.com, alltheweb.com etc.
There are also many problems to do with search engines, which we learned in the lecture. They are; that search engines may return too many results, some of the websites many have little relevance or quality.

What is a directory?A directory is human-edited, the web pages that are submitted are reviewed and added by manual submission, and this ensures the quality of the web site. After completing the submission process, web pages will be queued for reviewing by a human editor to listing.

Some examples of directories are; dmoz.org, directory.google.com, dir.yahoo.com, looksmart.com, about.com etc.
Tutorial (Work Shop Five)
this week in the tutorial we were to go into http://www.monash.com/spidap.html, a web site. After looking at the website we were to list four strategies that would help structure a good search.
This is what I came up with

1. Use more than one keyword when searching, make sure it is of relevance to what you are searching
2. When searching a phrase remember to use (“”), if this is not done the phrase you type will bring different results than expected.
3. Give some thought into what you want to search. Are you just beginning to just collect different information about a subject or have you got a particular objective in a broad subject.
4. Use the words “and” or “or” in your search criteria to make it specific.

After this task, we were to try an online quiz on history. I managed to finish it by using the four strategies I mentioned above. These strategies had a good effect and worked very nice. In this module I have learnt a lot about search engines and how one phrase without been search specifically can bring in a wide range of results that has nothing to do with the subject in the first place. When searching something, make sure to make it specific so the results are significant. Remember the World Wide Web is filled with many reliable and unreliable sources. It is always best to search something using thought, rather than guess or you will come upon a website that is completely off the topic.

Readings
Reading One: ‘Robert Harris-Web Search Strategies’
The first reading on web search strategies included such things as, an overview on the internet, categories you can find on the internet, search tool types, and various search tips. Which is all very informative.
Reading Two: ‘The History of the Internet: (Chap 4- Search Engines)’
The second reading include things such as how to find information on the web, types of directories, search engines, databases and library catalogues.
Reading Three: ‘Search Engine Optimization for Companies’
The third reading is very similar and includes topics to help you make a better search. For example the website tells you to 'set you benchmark'. This site is one you have to pay for, which is called a hidden website.
