- What is the difference between a web directory(aka search index) and a
search engine? What are the advantages and disadvantages of each?
- AskJeeves (www.ask.com) uses something your book calls "natural
language query interface"...what do they mean by that? Go to ask jeeves
and see if they talk about how their site works (look for ExpertRank). They also used to do something
trapping", why is that considered bad by many folks?
- What does a web "robot" or "spider" do? How is that helpful?
- There are specialized search engines that do not search the entire
web, but just parts of it. Find and copy the URL for a search engine that
searches for the following:
- Legal Information
- Discussion groups/mailing lists
- Boolean operators allow you to do some very complex searches.
How would you use them to search for chinese and thai food, where you
really like dishes with chicken or pork, but no peanuts, as you are
allergic? Type the phrase you would type into the search engine here:
- Compare these search engines. Find out what they offer in the way of
advanced search options, and what they don't offer.
- There are also specialized sites that offer different types of
information on the internet. One of them is wikipedia.org, what is it
about? Do you use it? And do you see any problems with it?
- Search for the homepage of "talk like a pirate day". How many sites
show up in google? In yahoo or one of the other search engines?
