Day 7: Invisible Web

this blog gonna be about Invisible Web(Database)

It's a web that contains text pages, files, or other often high-quality authoritative information available via the World Wide Web that general-purpose search engines cannot (due to technical limitations), or will not (due to deliberate choice) add to their indices of Web pages. It's normally also referred to as "Deep Web" or "Dark Matter".

It's also a collection of information stored in the form of data where their search engines do not index information stored in a database. It contains actual data or information. Many of the information are maintained by the government agencies and non-profit organization. It also contains contain articles, abstracts and citations, census data, patents, etc. Normally, the resul given are reliable, up-to-date information. But data in invisible web database often cannot be accessed via a general-purpose search engine. However, it is not the only solution to all of a researcher’s needs. Must be used in conjunction with other information resources. It has similar features compared to search engine. It also supports Boolean operators, phrase and proximity searches and also allow truncation.

A good example of invisible web for us is TP's Digital Library Portal Site.

As usual, i never knew what's invisble web till i attended this lesson. Even though all this while i'm using it, but i still thought it's a search engine but it's a TP's library Search Engine. So, fo now, i knew that it's known as invisble web(database) and not search engine.
