History of the Search Engine - What Came Before Google?
Although we credit Google, Yahoo, and other major search engines for
giving us the system we use to find the information we seek, the concept
of hypertext came to life in 1945 when Vannaver Bush urged scientist to
work together to help build a body of knowledge for all man kind. He
then proposed the idea of a virtually limitless, fast, reliable,
extensible, associative memory storage and retrieval system. He named
this device a memex.
But there is a long list of great minds that have given us the
information system we now use today. This article illustrates some of
them. Here is the History of the Search Engine:
Ted Nelson
Ted Nelson created Project Xanadu in 1960 and coined the term hypertext
in 1963. His goal with Project Xanadu was to create a computer network
with a simple user interface that solved many social problems like
attribution. While Ted's project Xanadu, for reasons unknown, never
really took off, much of the inspiration to create the WWW came from
Ted's work.
George Salton
George Salton was the father of modern search technology. He died in
August of 1995. His teams at Harvard and Cornell developed the Saltons
Magic Automatic Retriever of Text, otherwise known as the SMART
informational retrieval system. It included important concepts like the
vector space model, Inverse Document Frequency (IDF), Term Frequency (TF),
term discrimination values, and relevancy feedback mechanisms. His book
A theory of indexing explains many of his tests. Search today is still
based on much of his theories. History of the search engine uses some of
the same techniques even today.
Alan Emtage
In 1990 a student at McGill University in Montreal, by the name of Alan
Emtage created Archie; the first search engine. It was invented to index
FTP archives, allowing people to quickly access specific files. Archie
users could utilize Archie's services through a variety of methods
including e-mail queries, telneting directly to a server, and eventually
through the World Wide Web interfaces. Archie only indexed computer
files. With Archie, Alan Emtage helped to solve the data scatter
problem. Originally, it was to be named archives but was changed to
Archie for short.
Paul Lindner and Mark P. McCahill
Archie gained such popularity that in 1991 Paul Linder and Mark P.
McCahill created a text based information browsing system that uses a
menu-driven interface to pull information from across the globe to the
user's computer. Named for the Golden Gophers mascot at the University
of Minnesota, the name is fitting, because Gopher tunnels through other
Gophers located in computers around the world, arranging data in a
hierarchical series of menus, which users can search for specific
topics.
Tim Berners-Lee
Up until 1991 until there was no World Wide Web. The main method of
sharing information was via FTP. Tim Berners-Lee wanted to join
hypertext with the internet. He used similar ideas to those underlying
the Enquire (a prototype created with help from Robert Cailliau) to
create the World Wide Web, for which he designed and built the first web
browser and editor, called WorldWideWeb, and developed on NeXTSTEP. He
then created the first Web server called httpd, short for HyperText
Transfer Protocol daemon.
The first Web site built was at: http://info.cern.ch/ and was first put
online on August 6, 1991. Tim Berners-Lee created the World Wide Web
Consortium in 1994. Tim also created the Virtual Web library which is
the oldest catalogue of the web. The history of the search engine is a
fascinating story.
