Week Five Summary

Week fives lecture was about using search engines. The class was introduced to the three different categories of search engines.
1. The free, visible Web
2. The free, invisible Web
3. Paid databases over the Web

Search tools are divided into two main categories.
1. Search engines: A program on the Internet that works as a portal to help a person find a website by using keywords to search for them. The problem with search engines is that the return number of websites is usually too big and most of the websites' content is irrelevant.
2. Directories: Human-edited sites so users only get quality results. these are used more for finding answers to a query rather then finding a website.

The lecture also contain information about search engine interfaces, search engine interaction, common search engines and statistics on search engines.


Tutorial Activities


Four strategies that will help you structure are good search:

1. Create a phrase by putting key words in quotation marks " " to narrow down the results and achieve more relevant websites.
2. Start your search at the right place e.g. for a specific search go to a search engine, for a broader search go to a web directory.
3. If unsure where to start then your best bet is to start at a web directory
4. Try not to use stop words i.e. unimportant words too short or too common to be considered relevant strings on which to search

To finish this quiz took the main words from the questions and put them into quotation marks. this made my search more effective and even though I still had to go through some dud websites, the answer i was looking for wasn't too hard to find.

Reading One: Robert Harris "Web search strategies"

Most of the text was an extension of what was in the lecture. This still helped me further my knowledge on how to search effectively. Something that was not is the lecture was the FOREST LOG scheme: FO- Forms or variants of different words RE- Related terms ST-Synonymous Terms LOG- Ladder of generalisation.


Reading Two: History of the Internet (Chapter 4 - search engines)


The reading was about the history of search engines and web directories. It gave information on the first search engines and how they worked. This gave me insight to how far technology has come in just a few years. The reading also gave statistics to help the reader have some understanding just how big these search engines are and just how many files they hold.


Reading Three: Search engine optimisation for companies


This site is basically a company that analyses other companies websites and distributes them. This reading was a brief overview of what they actually do in order to give another company the most effective website possible.
