Module 4

Boolean searching task:

The biggest number of hits relating to these key words:

Using OR:

Semantic OR Web: would initiate a search for the individual words or both words combined.

Semantic

Web

http://www.google.com.au/search?hl=en&as_qdr=all&q=web&btnG=Search&meta

Semantic OR Web

Search Items	Results
Semantic	23,600,000
Web	4,210,000,000
Semantic OR Web	4,230,000,000

Information most relevant to what I actually wanted to look for:

Using Semantic AND Web AND Concepts: would initiate a search of sites that only contained these words and as I was searching for information on the concept of the Semantic Web, I could exclude reference to “applications”by using NOT and ().

(Semantic AND Web AND Concepts) NOT applications: http://www.google.com.au/search?hl=en&as_q=&as_epq=Semantic+Web+concepts&as_oq=&as_eq=applications&num=10&lr=&as_filetype=&ft=i&as_sitesearch=&as_qdr=all&as_rights=&as_occt=title&cr=&as_nlo=&as_nhi=&safe=images

Using Google, the number of results using a Boolean search with these parameters, came to 49.

Google doesn’t seem to recognize the Boolean Operators and substitutes its own “Implied Boolean Logic” instead with the use of + & - symbols. The following site address provides a list of corresponding Boolean Operators used by Google: http://www.googleguide.com/advanced_operators_reference.html

Information coming only from Universities:

1. http://www.google.com.au/search?hl=en&as_q=Semantic+Web+concepts+universities&as_epq=&as_oq=&as_eq=&num=10&lr=&as_filetype=&ft=i&as_sitesearch=&as_qdr=all&as_rights=&as_occt=any&cr=&as_nlo=&as_nhi=&safe=images – This search included the AND Universities – Results 849,000. The term “Universities” doesn’t limit the results to University sites.

2. Specialised search engines or nominated types of sites such as *.edu will focus on data from unique areas: http://www.google.com.au/search?hl=en&as_q=&as_epq=Semantic+Web&as_oq=&as_eq=&num=10&lr=&as_filetype=&ft=i&as_sitesearch=.edu&as_qdr=all&as_rights=&as_occt=title&cr=&as_nlo=&as_nhi=&safe=images This site is powered by Google but only brought up results from educational institutions. Results 15,400

Searches using different search engines would reveal different search results and each search would require several modifications to narrow down the search to get the best quality information.
