Alan Emtage, who had developed Archie, considered the first pre-web search engine in 1989, which later became a template for future search engines such as Google and AltaVista, said that web search has gone through a lot of phases and the next step will be a mix of human and artificial intelligence. He also spoke about privacy issues on internet.
Emtage, a Barbadian, the chief technical officer at New York-based Mediapolis, was in the city on Saturday to deliver a lecture 'Journey Of The Search Engine' at Amalthea, the annual technical summit of the Indian Institute of Technology, Gandhinagar (IIT-Gn).
On the future of internet search, he said the current fad is personalized search. "Starting from simple indexing in 1990s, today algorithms identify your previous searches and try to provide what is relevant to you. While it looks fantastic in the short term, in the longer term it can create a bubble outside which a person cannot see or think. The next step will be the use of artificial intelligence to sieve through terabytes of data. Creations like Watson by IBM can actually perform synthesis of information, by which many professional like lawyers, financial analysts and doctors work," he said.
On the outrage over 'internet snooping' by private and government agencies, Emtage said that the concept of online privacy is a double-edged sword. "Thinkers have long said that individual privacy is dead. As more and more information gets digitized and gets into the public domain, the situation is likely to worsen. There is no guarantee that a photograph clicked on a smartphone will not make it to certain websites. If we wanted privacy, we could have developed the web differently. Now we're two decades too late," said Emtage.
Emtage took the audience through the development of Archie, "Earlier it was a simple index search like you search a book by its title in a library but can't see its contents. Then came Page Rank by Google that introduced 'comparative' search on the basis of the pages searched by others. Today the web has become a giant network of information islands," he said.
