= How do you see the future?
The Internet is, as I see it, a fantastic gift to humanity. It is, as one of my graduate students recently said, the next step in the evolution of information access. A long time ago, information was transmitted orally only; you had to be face-to-face with the speaker. With the invention of writing, the time barrier broke down — you can still read Seneca and Moses. With the invention of the printing press, the access barrier was overcome — now anyone with money to buy a book can read Seneca and Moses. And today, information access becomes almost instantaneous, globally; you can read Seneca and Moses from your computer, without even knowing who they are or how to find out what they wrote; simply open AltaVista and search for "Seneca". This is a phenomenal leap in the development of connections between people and cultures. Look how today's Internet kids are incorporating the Web in their lives.
The next step? — I imagine it will be a combination of computer and cellular phone, allowing you as an individual to be connected to the Web wherever you are. All your diary, phone lists, grocery lists, homework, current reading, bills, communications, etc., plus AltaVista and the others, all accessible (by voice and small screen) via a small thing carried in your purse or on your belt. That means that the barrier between personal information (your phone lists and diary) and non-personal information (Seneca and Moses) will be overcome, so that you can get to both types anytime. I would love to have something that tells me, when next I am at a conference and someone steps up, smiling to say hello, who this person is, where last I met him/her, and what we said then!
But that is the future. Today, the Web has made big changes in the way I shop (I spent 20 minutes looking for plane routes for my next trip with a difficult transition on the Web, instead of waiting for my secretary to ask the travel agent, which takes a day). I look for information on anything I want to know about, instead of having to make a trip to the library and look through complicated indexes. I send e-mail to you about this question, at a time that is convenient for me, rather than your having to make a phone appointment and then us talking for 15 minutes. And so on.
*Interview of August 8, 1999
= What has happened since our first interview?
Over the past 12 months I have been contacted by a surprising number of new information technology (IT) companies and startups. Most of them plan to offer some variant of electronic commerce (online shopping, bartering, information gathering, etc.). Given the rather poor performance of current non-research level natural language processing technology (when is the last time you actually easily and accurately found a correct answer to a question to the Web, without having to spend too much time sifting through irrelevant information?), this is a bit surprising. But I think everyone feels that the new developments in automated text summarization, question analysis, and so on, are going to make a significant difference. I hope so!—but the level of performance is not available yet.
It seems to me that we will not get a big breakthrough, but we will get a somewhat acceptable level of performance, and then see slow but sure incremental improvement. The reason is that it is very hard to make your computer really "understand" what you mean—this requires us to build into the computer a network of "concepts" and their interrelationships that (at some level) mirror those in your own mind, at least in the subjects areas of interest. The surface (word) level is not adequate — when you type in "capital of Switzerland", current systems have no way of knowing whether you mean "capital city" or "financial capital". Yet the vast majority of people would choose the former reading, based on phrasing and on knowledge about what kinds of things one is likely to ask the Web, and in what way.
Several projects are now building, or proposing to build, such large "concept" networks. This is not something one can do in two years, and not something that has a correct result. We have to develop both the network and the techniques for building it semi-automatically and self-adaptively. This is a big challenge.
