The Invisible Web or Deep Web, Part 3 -- Two search challenges

---

A.
Go to the Boolean search form for the Canadian Patents database. At most online databases, like this one, you do not have to write your entire Boolean query; the Boolean operators can be chosen from menus.

Try the following four sample searches (answers to be given later in class).

1. -- Find, by list of fifty, the patents that were issued between October 1, 1989, and December 31, 1999, and contain "controller" in the Title field and "Smith" in the Owner field.


2. -- Find the number of patent documents that contain in the Title field the word "tooth" and also "brush" or the word "toothbrush".

3. -- Find the number of Canadian patent documents under the IPC subclass "A63B" or "A63C" which has been laid open in 1999.

PowerReporting is an online resource for journalists operated by the prestigious Columbia School of Journalism. It offers a challenging "Web Treasure Hunt" to for its students. The ten-question test goes beyond the kind of searching we cover in our course, but trying the test will open your eyes to new possibilities.

Be sure to spend some time looking for the information before you
(1) look at the Hint, and finally
(2) look at the answer.

The Invisible Web, or the Deep Web, Part 1 -- Introductory exercise

Your grandparents are planning to go on a Caribbean cruise. Their travel agent has found them a very attractive package with a cruise ship leaving Miami, Florida called the Grand Caribe. The package is at the right price, for the right length of time, stopping in all the ports they want. But you remember seeing in the news some time ago reports about mass illnesses on some cruise ship and there was the suggestion that proper health measures were not taken on board the ship.

Has the Grande Caribe ever had serious health problems with passengers? If so, how long ago? How safe is it now? Find some useful information about the health condition of the cruise ship Grand Caribe. Inspection reports by government health inspectors would be most useful.

Hacker gets 20 years and will have to pay millions

Normally I don't post news about hackers - I don't expect any of you to become that sort of criminal - but this case is a special one. The news should be spread to everyone so that the bad guys can never say they were just hacking for fun and didn't know it was so serious. This article is from Wired magazine -

Advanced Search Techniques -- Boolean Operators & Venn Diagrams

Use the Websites below to learn about the following topics. Make your own notes.

BOOLEAN OPERATORS (AND, OR, NOT)
COMBINING MULTIPLE OPERATORS
PARENTHESES
NESTING
TRUNCATION
VENN DIAGRAMS

Serious research often requires you to search professional databases. While they allow simple keyword searches such as the kind you use with search engines like Google, they also offer much richer resources for finding information, including field searches and Boolean operators.

A. BOOLEAN OPERATORS

---

The first thing to learn about is the Boolean operators AND, OR, NOT (and sometimes NEAR).

We will introduce Boolean operators briefly in class. Then you should learn more by visiting a number of websites.

1. Begin at the following site and work through the 3-5 minute tutorial on Boolean operators:
   http://lib.colostate.edu/tutorials/boolean_info.html
   
   
2. Continue the same tutorial to the section entitled Advanced Boolean Tutorial (3-5 minutes) at
   http://lib.colostate.edu/tutorials/booleanadv_info.html
   
   
3. Carefully read the summary page at
   http://lib.colostate.edu/howto/others/boolean.html
   
   
4. Work through the four interactive demonstration searches at
   http://writing.colostate.edu/demos/boolean/index.cfm
   Note: There may be a temporary problem with these demos. If so, move to the next exercise below.
   
   
5. Learn about parentheses, truncation and wild cards at
   http://www.gv.psu.edu/foweb/lib/boolean_search/parenth.html
   or truncation at http://www.montgomerycollege.edu/library/libtp/instructions/Nursing/truncation.htm and wild cards at http://www.montgomerycollege.edu/library/libtp/instructions/Nursing/wildcard.htm
   
   
6. Learn how to combine Boolean operators, parentheses and truncation to solve difficult search problems at
   http://www.askscott.com/examples.html

B. VENN DIAGRAMS

---

Venn diagrams go hand-in-hand with Boolean operators. In fact, they are just a visual representation of AND, OR & NOT.

1. See the connection between Boolean operators and Venn diagrams by going through the tutorial at
   http://www.lib.lsu.edu/instruction/searching/searching09.html
   A similar presentation is given at
   http://www.gv.psu.edu/foweb/lib/boolean_search/and.html
   
   
2. View the very helpful videos and images for Venn diagrams at
   http://www.lib.washington.edu/uwill/research101/Search07.htm#1
   Similar illustrations are make Venn diagrams clear at
   
   
3. Learn how to use more complex Venn diagrams at
   http://lib.colostate.edu/howto/others/venn.html
   
   
4. Check how well you're doing with this review, which includes test questions at
   http://newterra.chemeketa.edu/library/instruction/tutorials/boolean/boolean.htm
   
   
5. Test your knowledge of Venn diagrams at
   http://www.engr.iupui.edu/%7Eorr/webpages/cpt120/venn/venn/toc.htm
   NOTE: This site uses operators from mathematical set theory, but we can interpret them as follows: the symbol ∩ means AND, the symbol ∪ means OR, the symbol – means NOT.
   Ignore Question #5 with the symbol Δ (if you're curious, it means the symmetric difference of two sets, that is, the set of elements which are in one of either set, but not in both).
   

Some sample test questions are online at http://tinyurl.com/2gkjxm Our test on search techniques will have some questions like these. WHEN YOU HAVE WRITTEN DOWN YOUR ANSWERS, check them with the correct answers at http://tinyurl.com/36bscj Finished your work early?

another poor kid gets nailed for sharing illegal files

Appeals Court Raises Fine in Filesharing Case (February 26, 2010)

A US federal appeals court has ordered Whitney Harper, now 22 and a
senior at Texas Tech University, to pay US $27,750 for 37 music files
she shared when she was in high school. The ruling overturns a lower
court decision that imposed a fine of US $200 for each song, or US
$7,400. Harper and her attorney maintain she did not know that she was
breaking the law when she shared the music over Limewire. The lower
penalty was decided when the lower court agreed that she was an
"innocent infringer" under US copyright law. The appeals court noted
that the "innocent offender" defense is invalid because the CDs from
which the music was shared contained copyright notices. Harper's
attorney is considering appealing to the US Supreme Court.
