The Deep Web

Page 8: The Visible  Web

The Deep Web• (aka The Invisible Web, The hidden Web)

Page 9: The Visible  Web

The Deep Web• (aka The Invisible Web, The hidden Web)

• The deep Web is the part of the Internet that is inaccessible to conventional search engine’s, and to most users.

Page 10: The Visible  Web

The Deep Web• (aka The Invisible Web, The hidden Web)

• The deep Web is the part of the Internet that is inaccessible to conventional search engine’s, and to most users.

• search engines have found ways to integrate deep Web content into their central search function.

The Deep Web• (aka The Invisible Web, The hidden Web)

• The deep Web is the part of the Internet that is inaccessible to conventional search engine’s, and to most users.

• search engines have found ways to integrate deep Web content into their central search function.

• Even a search engine as far-reaching as Google provides access to only a very small part of the deep Web.

Beyond Google: Searching the Invisible Web

Google is a great search engine,

Page 14: The Visible  Web

Beyond Google: Searching the Invisible Web

Google is a great search engine,

• But it misses a vast amount of information that is generally "invisible" to its Internet spiders and crawlers

Page 15: The Visible  Web

Beyond Google: Searching the Invisible Web

Google is a great search engine,• But it misses a vast amount of information that is generally

"invisible" to its Internet spiders and crawlers• Most are tucked away in databases and dynamically-generated

pages.

• Most are tucked away in databases and dynamically-generated pages.

• These hidden gems are often referred to by search analysts as the "invisible Web" or "deep Web."

Google is a great search engine,• But it misses a vast amount of information that is generally

"invisible" to its Internet spiders and crawlers• Most are tucked away in databases and dynamically-generated

pages.• These hidden gems are often referred to by search analysts as

the "invisible Web" or "deep Web."• One way to mine the invisible Web is to use a specialized deep

Web search engine or directory.

• These hidden gems are often referred to by search analysts as the "invisible Web" or "deep Web."

• One way to mine the invisible Web is to use a specialized deep Web search engine or directory.

• These allow you to directly search thousands of searchable databases and specialty search engines in one step.

• The slower but more useful method for mining the deep Web

Page 20: The Visible  Web

• The slower but more useful method for mining the deep Web • is something you probably already do as part of your research.

Page 21: The Visible  Web

• The slower but more useful method for mining the deep Web • is something you probably already do as part of your research.

• The deep Web includes databases and collections searchable

• Many major free databases such as the IGI and Ellis Island Records• are part of this so called "invisible web“• and their data won't come up in most standard search engine

searches.

• The trick to using this "invisible" data

Page 28: The Visible  Web

• The trick to using this "invisible" data• Is to learn what resources might have information pertinent to

your area of research.
