Tutorial summary
This tute session involved reviewing website such as http://www.monash.com/spidap.html, to generate a list of four strategies that will help structure a good search. We then completed an internet quiz which can be found by clicking on the following links: http://www.siteseen.co.uk/questions/historytrivia/. Moreover, we were required to use the four search strategies to help us find the answers on various search engine. After visiting http://www.monash.com/spidap.html, some of the four search strategies are as follow:
- Know where to look first
- Fine-tune your keywords
- Be refined
- Query by example
During the course of the online quiz, i experienced some difficulties answering some question. To help me find the answer to those questions, i visted google. Furthermore, i used three out of the four search strategies to ensure my search was as effective as i can possibly make it. First of all, i knew where to look first. i started off by going to google as it's a widely used search engine. Second, i fine-tuned my keywords and used some search tips which i learned earlier in this course. I used double quotation marks and the plus and minus sign to ensure it's suched as it is, and to also force the inclusion and exclusion of various words. Thirdly, i refined my search. These, three strategies combined, were very effective as it didn't take me long to find the answer to the quiz. So far in this module, i have learned a number of things. First of all, i have learned that alot of information on the web can be from a non credible source. Furthermore, the information can be out of date. Secondly, there are human edited source known as directories. This ensure that information presented are current and valid. Thirdly, i haved learned that there are alot of problems associated with search engines. There are often too many result with irrelevant content or the contents are usually out of date or erroneous. On the other hand, there are strategies which can be applied to reduce such problems. These include, fine-tuning your keyword, query by example, knowing where to look first and be refined. To add to this, i have learned some very important information in this tutorial session. Since i now know the four search strategies, i will be able to take on the upcooo2 research assignment.
Reading 1: Robert Harris-Web Search Strategies
On the web, informations are placed into 3 categories. These categories are, Free, Visible Web, Free, Invisible Web and finally, Paid Databases over the Web. When searching on a particular topic, be sure to include variants of the word used or try to find alternative words instead of the original word in the phrase. Moreover, puting your phrase in a quotation mark ensure it's searched actly as it is. Using more than one search engine will give you more hits. Typing only one keyword will have too many hits of which many are irrelevant. On the other hand, using several keywords will minimise the hits to the most relevant. You will also need to decide whether you are looking for anyone's opinon on the topic or an expert's view. moreover, you can guess the website by puting the name in the middle. e.g. for information on harvey fresh, you can try look it up at http://www.harveyfresh.com/. Finally, if you forgot to write down the url of the page in which you retrieved certain document, simply look for the most unusual phrase in the document and type it into a search engine.
