10 Questions On Innovation

by Roberto V. Zicari

August 2007–
In my work as Editor of ODBMS.ORG
I started a Section on Innovation.
I believe this is important. In the IT industry innovation plays a key role.
But how does innovation occur? I thought the best way is to ask who did some mayor innovation..

So I asked:

Ivar Jacobson. creator of OO methodologies
Alan Kay, pioneer of OOP, PC, and GUI
Vinton G. Cerf, father of the Internet
Philippe Kahn, founder of Fullpower, LightSurf, Starfish, and Borland

You can read in this blog their answers to my 10 Questions On Innovation.

Learning from great innovators is one source of inspiration, but not a guarantee of course…

Enjoy.

My Visits at Google and IBM Almaden Research

by Roberto V. Zicari

August 16 2007–
This summer I was in the Bay Area. I took the occasion and visit IBM Almaden Research and Google.
I gave a presentation both at IBM and Google on my research project, Gugubarra.

Here are some details:

Title of the talk:
The Gugubarra Project: Building and Evaluating User Profiles for
Visitors of Web Sites.

Speaker: Roberto V. Zicari
Computer Science Department,
Goethe University of Frankfurt, Germany.

Work done in cooperation with Natascha Hoebel, Sascha Kaufmann,
Karsten Tolle, Naveed Mustaq.

Index Terms: User Profiles, Web Communities, User modeling, Clustering methods

—————————————————-
Abstract

In this talk I will present an overview of the work we are
currently doing in the Gugubarra project. The project aims at
building tools for better managing communities of Web visitors.

The Gugubarra project (Gugubarra is the Aboriginal name for the
Kookaburra bird) began in 2004 within the database group (DBIS)
at the Computer Science Institute of the Johann Wolfgang Goethe
University, with the aim to build tools for better managing
communities of registered Web visitors.

In this talk I will present the results of the project so far
and outline some open research issues.

The starting point of our project is the assumption that a
community of users is registered on a Web site and that for each
user a profile is built. A User profile is based on the actions
and navigations the user performs on the Web site.

In Gugubarra, we offer various settings that can be used to
create and manage user profiles. By using these settings the Web
site owner can focus on those aspects he wants to analyze.

The approach we have in Gugubarra is as follows:

i) For each registered Web visitor we create a profile.
These user profiles reflect the “inferred” interests of the
users related to a set of pre-defined topics defined by the owner of
the Web site. The profiles go beyond collecting the obvious
information the user is willing to give at the time of
registration. In Gugubarra, a user profile contains two parts:
the obvious profile, given directly by the user and a non
obvious profile (NOP), inferred by the user’s behavior during his visits
on the site.

ii) A user profile is (re)-calculated dynamically any time an
explicit feedback is given by the user and/or a set of events
occurred which are related to the user’s behavior and to certain
“locations” of the Web site.

iii) We cluster Web visitors by clustering similar profiles of
interest [5]. Cluster of Web visitors can then be used to
analyze patterns of interests in the Web community and to forecast
further behavior. Clusters might also provide useful information
to support the decision what kind of new E-services to introduce
for the Web community and when to introduce them.

A first research prototype system, called Gugubarra 1.0 has been
implemented in 2004 [1], which allows to build and manipulate
non-obvious user profiles. It was showcased at the CeBIT Trade
Fairs in 2004 and 2005. Gugubarra 1.0 works as a test
application on real data provided by the Web community viewzone.org.

A new prototype system, Gugubarra 2.0, is currently being
designed [3], [2] which includes a more sophisticated approach
to the definition of non-obvious user profiles and allows
clustering users by interests [4]. In this talk I will focus mainly on
the new features introduced in Gugubarra 2.0 and refer to [6] for
the features implemented in Gugubarra 1.0

10 Questions On Innovation to Ivar Jacobson

by Roberto V. Zicari

August 2007–
Dr. Ivar Jacobson is one of the great thought-leaders in the software world where he has made several seminal
contributions. He is one of the fathers of components and component architecture, use cases, modern business engineering, the Unified Modeling Language and the Rational Unified Process. He is the principal author of five influential and best-selling books. He has written more than 50 papers and he is a regular keynote speaker at large conferences around the world.

1. Who are your favorite innovators?
[ivar] I am very impressed by some innovators that have made the world a better world, but I really don’t have any favorites. My favorites are found in other spaces such as sport, music and art.

2. What do you consider are the most promising innovations of the last 3 years?
[ivar] I have not given this question any thoughts.

3. What helped you to become a successful innovator?
[ivar] I have never seen me as an innovator. I have tried to solve problems we have with software, but I guess that could be seen as innovations. I introduced components in 1967 as a means to build software architectures that could change gracefully over many years and that could be reused for many different applications. I introduced use cases to get more understandable requirements at the same time as they worked as test cases.

4. Did you pay a price to be an innovator? Which one?
[ivar] Being a manager for a large project and at the same time fighting for a better way of building software is professional suicide. After having introduced components at Ericsson it took ten years before the company knew it had created history in the telecom space. In the mean time I was demoted and recommended to leave the company. The recommendation was given by my boss who later became the president of Ericsson.

5. What are the rewards to be an innovator?
[ivar] I never came up with an idea to be rewarded. Components made it possible to develop a product that could be adapted to every customer with small costs and made it possible for me to do what I had been asked to do. Use cases streamlined the life cycle since use cases were test cases. However, later I have been rewarded because people adopted these ideas. I have been able to work with fantastic people around the world and make a living out of it.

6. What are in your opinion the top 3 criteria for successful innovation?
[ivar] This is a new question to me, but I will give it a try. An innovation should 1) be practical, 2) stand on a good theoretical foundation, and 3) be simple to understand. I usually quote Kurt Lewin: There is nothing as practical as a good theory. Even a rather complex idea must be presentable in a simple way.

7. What would you recommend to young people who wish to pursue innovation?
[ivar] First of all, don’t make it your goal to become an innovator. If you have good ideas, you will have to fight for them. Many people have good ideas, but most give up due to the resistance that comes from the establishment. Success requires perseverance. On the other hand don’t become greedy. Don’t focus on making money, but be generous with your ideas. You have more ideas that you can harvest from later on. And have fun.

8. In your opinion how can we create a culture that supports and sustains innovation?
[ivar] There are many obvious answers to this question so I will try something different: First, in Sweden there was a time when we had no world class tennis players. Then we got Bjorn Borg. After Bjorn Borg we got many world class tennis players. We have similar effects in other areas. If someone has great ideas, let her or him work with promising people and they will all soon be more interested in coming up with new ideas. In my companies I have had great people around me that now are very alert for new ideas. For example Gunnar Overgaard, Per Kroll, Agneta Jacobson, Maria Ericsson, Dave West, Patrik Jonsson, Pan Wei Ng, Ian Spence, Kurt Bittner, Magnus Christerson, Stefan Bylund. Nothing is as effective in growing an innovative culture as working with innovative people.

In big companies actively supporting alternative careers has been very effective in growing an innovative culture.

9. What do you think stops/slows down innovation?
[ivar] I can’t think of anything more than the obvious answers.

10.Do you think becoming an innovator can be taught?
[ivar] Absolutely

10 Questions On Innovation to Alan Kay

by Roberto V. Zicari

April 2006 – Alan Kay is one of the earliest pioneers of object-oriented programming, personal computing, and graphical user interfaces. He invented or co-invented object-oriented programming; Smalltalk; the 1968 FLEX Machine, a desktop computer with graphical user interface and object-oriented operating system; the Dynabook, a laptop computer for children; Alto, the first networked PC; and participated in the design of the ARPAnet.

1. Who are your favorite innovators?
Hundreds if not thousands of important innovators have flourished over the 400 years that we’ve had real science, and antiquity shows that even though it was much harder to innovate in the deep past, there have been deep seminal thinkers operating in most generations. My interest in reading all sorts of things makes it difficult to set down a short list here. (Who doesn’t love Archimedes, Eratosthenes, Aristarchus, etc.?)
In our own time and my own field, I was particularly struck by the ideas of Licklider (man-computer symbiosis), Ivan Sutherland (invention of interactive computer graphics and object oriented modeling), Dave Evans (the father of continuous tone 3D graphics), Nygaard and Dahl (Simula), Bob Barton (the B5000 computer), John McCarthy (Lisp), Seymour Papert (Logo and constructivist education), Marvin Minsky, Doug Engelbart, Bob Taylor, etc.
In my own generation I’ve been tremendously impressed by the work of Butler Lampson, Chuck Thacker, Dan Ingalls, Adele Goldberg, Vint Cerf, Bob Kahn, Nicholas Negroponte, Carl Hewitt, Paul MacCready, and many more from the 60s and 70s communities funded by ARPA and Xerox PARC.
In the generation(s) after me, I have been very impressed with Dave Reed’s distributed object system, Bill Atkinson’s Hypercard, Mitchel Resnick’s starLOGO, Brewster Kahle’s file systems, Doug Lenat’s CYC research, Takeo Igarashi’s UI work, etc.
The Draper Prize of the NAE is aimed not just at engineering feats but at those that really got out there and benefited humanity:
integrated circuit, jet engine, GPS, Internet, Personal Computing, etc.
One of my favorites from the early 19th century is the guy who invented the hydraulic ram pump, a truly elegant simple outstanding machine.

2. What do you consider are the most promising innovations of the last 3 years?
I can’t think of any in computing (we are in a very incremental and almost moribund period in our field) but this could simply be “old-fogeyism” on my part. If the content of the $100 Laptop is done well and we can figure out how to help the helpers of the children who will get them, then this should qualify as a grand innovation (perhaps in 2008?).
But if we widen the scope, there are some very promising ideas that grapple with some of the largest human problems.
a. For example, about 70% of the world does not have drinking water of high enough quality. The conversion of low quality water to high quality water requires both new technologies (e.g. membranes for reverse osmosis) and energy (for forcing water backwards through the osmotic membranes, or distillation, etc.). Some very good things are now being done here, including a very inexpensive and efficient tidal-powered high quality water producer, etc.
b. I forget when the modifications to bacteria to produce fuel from garbage were done. The insulin modification was done longer ago, but I think I recall seeing that some good fuel production recombinant modifications were done more recently. I think we could claim that the progress in this general area are such to be a promising innovation.
c. Another innovation that has gotten particularly important over the last 3 years is the joining of a number of fields into a real brain science, that has led to a much better understanding of brain chemistry, process, psychology, and pharmacology.

3. What helped you to become a successful innovator?
No one has benefited more from their community than I have (see: “The Power of the Context” – PDF). Beyond that, my interest in helping children learn how to think (catalyzed by Papert and my dismay with adult behavior) and wide reading got me hooked into the deep implications of computing as the next 500 year “big deal” since the printing press. This made it much easier to not get sucked into the whirlpool of current technical problems and to focus on “what should the technology be doing regardless of what it is doing now?”. Also, “artists” are people who have to do art regardless of all else, and fundamental research and engineering is an art form whose best practitioners are kind of compulsive about making things happen. Xerox PARC was a concentration of technological artists with enlightened funding and organization provided by Bob Taylor. It was the perfect atmosphere for people with artistic visions.

4. Did you pay a price to be an innovator? Which one?
Interesting question. Beyond some of the compulsive behaviors (which can get a little too total), I would say “no” with regard to the 60s and most of the 70s. In the last 25 years there have been far fewer funding sources that have the enlightened model of ARPA and Xerox PARC. I don’t have any interest in “computing as a job” but only in trying to round off the first phase of the invention of personal computing, especially forchildren. This hasn’t really happened yet, and it is disturbing to see the poor subset of personal computing that is vended and generally accepted today.
So the price today is much higher than when mainframe people were calling us crazy for trying to do personal computing. That was nothing. What’s harder today is that people think they’ve got personal computing and they don’t really. The analogy here is between the jump from non-literacy to the printing press (which might be fought but the chasm that is to be crossed is clear) vs. the much trickier one of trying to explain to a culture that has the printing press and universities that it is not very well educated and thinks pretty poorly (for example, the US is in this general state — it has the trappings but not the perspective to see how poorly educated most “educated people” actually are).

5. What are the rewards to be an innovator?
I think this differs with the personalities of the innovators. I felt most rewarded when an idea really worked out as imagined (this is a biggie if you have to leave present realities to do the imagining), and also it is a big deal to me that I was funded by ARPA and Xerox PARC (in fact I got better funding as a post-doc in constant dollars and environments than I do today). That is quite a statement to make, but it’s quite true.
A terrific byproduct is that I’ve been able to meet with many of my heros, and work with quite a few of them. That has been very exciting.
My main feeling about the much later awards and medals is that (in our case at least) they miss the actual community-synergistic process. I think this is generally true about work that has a lot of engineering and building of stuff as part of it. As many important things come out of the building as in the original visions, yet the awards tend to celebrate the visions more than the larger process.
So actually getting to do the work with others of like mind has been the big thrill and reward.

6. What are in your opinion the top 3 criteria for successful innovation?
A lot depends on the time scale of requisite change. I’ve been more of an inventor than an innovator, in that I think innovation also has something with getting stuff into the larger world. Most of my ideas that have gone out into the world have been taken there by others.
Example of short time scal
e: the Google folks did not invent the Internet or search engines. They had a particular idea about what was important and concentrated on that, hung in there, and have been successful. I think most innovation is like that: limited invention and ability to couple to existing structures. The ideas that require a general learning curve are more difficult to innovate.
For example, if you look at the grand dreams of the ARPA community, most required large changes both with technology and society. At PARC we decided (rightly) that we would have to build all of our HW and all of our SW to avoid artificial blocks from current practice. The first order theory is: this is crazy! But the second order theory says: if you can do it, then you must do it! A few years before, when we were all in ARPA research (and one of the joint projects was to do the ARPAnet), the IMP “routers” were made to order in one of the projects because no vendor equipment would do.
One way to answer the question is to note that the personality types and motivations of the inventors and innovators I’ve known have been rather different. A lot of different types can be successful. However, the ability to compulsively focus on a goal (short or long term) seems to be quite common across types. The more artistic and grand the goals, the more deep self criticism (without degenerating into the immobilization of depression) is required. This is not easy, because it has to be combined with an almost boundless confidence (but one that is not stupid about current goodness of idea). Since most ideas (even by talented people who have lots of ideas)are mediocre down to bad, the combination of criticism and optimism is a tricky important dance.
You’ve got to have lots of ideas, you’ve got to get rid of most of them, you’ve got to think that the visions are doable.

7. What would you recommend to young people who wish to pursue innovation?
Again, the best strategies depend on personality and motivational types. My type is “lone wolf” but I realized in grad school that what I wanted to do could not be done by myself. This led to quite a bit of conflict before I was able to start to adjust to the idea that I would have to set up a research group of folks whose talents were complementary to mine and somehow try to guide it. I wasn’t terribly good at this, but we managed to get some things done.
So the simple advice here is to
(a) try to understand both one’s strengths and weaknesses. The best plans require strategies for both.
(b) It’s pretty hard to get by without gaining a fair amount of knowledge. Some innovators concentrate in their field (or a sub-field), and others draw on many fields for inspirations and analogies. Many technologists today are quite ignorant of history (even in their own field), and this leads to some really horrible blind attempts to reinvent. Awareness of history and anthropology in the large can relate technologists to the larger human condition and the actual end-users of their ideas. The needs that can be gleaned from history, etc., can also be a great source for ideas.
(c) Avoid taking your identity from your “product” or “process” or “possessions” or “peers” — instead try to identify with your “potential”. I.e. don’t become a “brand”. This has always been a bit of a problem in computing, but seems to be much bigger today (and getting still bigger) for individuals, groups, companies, and countries. Potential allows looking ahead and changing in a way that the other “p’s” don’t.
(d) As Jim Watson likes to say: if you are the smartest person in the room then you are in the wrong room. The genius of Bob Taylor at PARC was to get very good people in a designed environment so that no one was the smartest person in the room. This was very powerful.
(e) Learn how to hang in there.

8. In your opinion how can we create a culture that supports and sustains innovation?
Well, we had one until a few decades ago (and if you put more weight on incrementalism, we still have one). Awareness, scope, and multiple perspectives are all things that real education is supposed to magnify. The lack of real education (and really educated people) especially in the US is a disaster on many fronts. Once a culture gets to the point where it can’t tell whether it is educated or not, it is in real trouble. One of the main goals of education early on is to give a sense of what there is to be known, and the thresholds required. One way to look at the US is that a little over 1% of US adults are scientists, engineers, mathematicians and physicians. That plus the industrial revolution to magnify the results of this small group gives the US the illusion of being a modern civilization. But if you take the industrial revolution away, it starts to look more like a 3rd world country.
A simpler way of looking at this is that any culture that requires war and threat of war to spend on research is missing the self-awareness to climb into the next stage of civilization.

9. What do you think stops/slows down innovation?
People who would rather be in control of mediocre to moribund processes rather than feel out of control with possibly great processes. This has been the big change in funding over the last 30 years.

10.Do you think becoming an innovator can be taught?
Well, with reference to my debts to my own community, I would say “yes, up to a certain extent”. To return to my soapbox on education, real education requires the following to happen to a mind: to create “a new field/idea/technology/path (either radically or incrementally) which had a profound (positive) impact on a particular subject area/field” (which is pretty much your definition of innovation). In other words, we have to do invention/innovation in our own heads to get educated and to learn how to think, and this is not easy for anyone, and it is quite difficult for many, but doable.
Another way to look at these questions from a wider point of view is that the ultimate aim of education is really to learn how minds work, especially human minds, and most especially our mind.

10 Questions On Innovation to Vinton G. Cerf

by Roberto V. Zicari

February 2006 – Vinton G. Cerf is vice president and chief Internet evangelist for Google. Widely known as one of the “Fathers of the Internet,” Cerf is the co-designer of the TCP/IP protocols and the architecture of the Internet. In December 1997, President Clinton presented the U.S. National Medal of Technology to Cerf and his partner, Robert E. Kahn, for founding and developing the Internet.

1. Who are your favorite innovators?
There are inventions whose inventors I don’t know so the latter question has some relevance. Dean Kamen is one of my favorite innovators because he’s a fearless engineer. Similarly Burt Rutan and Paul McReady are equally able to think of solutions out of the ordinary. Tim Berners-Lee for the WWW. Fred Smith for inventing FEDEX. Steve Jobs for his stunning ability to gauge the market for new devices/services. There are many more.

2. What do you consider are the most promising innovations of the last 3 years?
Carbon Nanotubes that have such a variety of potential applications.
Broadband communication over power lines (experiencing a renewal of interest with new economics;
Netflix – re-inventing DVD rental business.

3. What helped you to become a successful innovator?
Long term support for research by the Defense Advanced Research Projects Agency; widespread participation in the design, implementation, deployment and operation of the Internet by thousands of companies and individuals; a philosophy of openness; and not constraining the Internet’s evolution by patenting its technology.

4. Did you pay a price to be an innovator? Which one?
My famiy paid a price – I wasn’t around much and still travel a great deal.

5. What are the rewards to be an innovator?
When your ideas take root and benefit from the support of many people, when businesses are built around them and when the world’s population appears to get benefit from them, how can you not feel very amply rewarded for your part it the creation?

6. What are in your opinion the top 3 criteria for successful innovation?
A) don’t be afraid to re-visit old ideas – times, technology, tastes, economics change and may make an unworkable idea into a winner.
B) Listen to experts but don’t be constrained by them
C) Perseverence counts.

7. What would you recommend to young people who wish to pursue innovation?
Find something you are good at and stick with it. Successful innovators are not afraid of hard work and long hours and perseverance in the face of adversity and even ridicule.

8. In your opinion how can we create a culture that supports and sustains innovation?
Celebrate innovation; show our young children that innovators are not just those that make a lot of money – they are also the ones who bring fresh, new ideas to the table. Encourage exploration.

9. What do you think stops/slows down innovation?
Rigid training methods that stifle innovation; failure to recognize alternative paths to creativity; positive feedback for out of the box thinking.

10.Do you think becoming an innovator can be taught?
I think conditions can be created to allow innovators to flourish but I am not sure this is something that can be taught.

Welcome to ODBMS.ORG

by Roberto V. Zicari

Dott. Roberto Zicari is editor of ODBMS.ORG, the most up-to-date collection of free materials on object database technology on the Internet. ODBMS.ORG was created to serve faculty and students at educational and research institutions as well as OO software developers in the open source community or at commercial companies. It is designed to meet the fast-growing need for resources focusing on object database technology and the integration of object-oriented programming and databases.

Roberto is Full Professor of Database and Information Systems at Frankfurt University and representative of the OMG in Europe. Previously, Roberto served as associate professor at Politecnico di Milano, Italy; Visiting scientist at IBM Almaden Research Center, USA, and the University of California at Berkeley, USA; Visiting professor at EPFL in Lausanne, Switzerland, and at the National University of Mexico City, Mexico.

Dear Visitor!

The idea of this Web portal originated during a meeting I had with Christof Wittig of db4objects in June 2005. Christof asked me if I was interested to create an Educational Program to help promoting and further use of object databases for the researchers and developers communities.

I was intrigued by this idea. My interest in Object Technology in general and Object Databases in particular is rooted back in the mid 80s. First at IBM Research Center in Almaden , San Jose in 1985 and 1986 , where I worked with colleagues at the definition of an extension of the relational data model to accommodate complex data structures , and then starting in 1989 for a few years where I had the privilege to join in the design team of the Gip Altair project in Paris later to become O2, producer of one of the first object database product in the world, and to the best of my knowledge the first commercial object database product made in Europe.

For me as a young researcher at that time, it was an incredible challenge. I had the possibilities to see my research ideas turned into reality and incorporated into a product that was supposed to replace the existing relational database systems on the market…

This did not happen.

Years later, relational database systems are still very well established, and only a few commercial companies offer object database systems.

So why embarking into this project? At first glance it looks like a challenge, not obvious, and perhaps this is one of the reasons why I like this project, but there are important factors that made me think and convince to accept to conduct this project.

First, Object Technology is main stream since years now. Both for modeling, UML, and for programming environments, Java, C#. Code generation, MDA, patterns, platforms, objects are all over. This is very different than in the mid 80s early 90s when object modelers and developers were early adopters.

Second, the Open Source community clearly demonstrated the feasibility of their ideas that Open Source is more than simply a number of talented developers around the world cooperating together, but it is also a viable business model. Examples of these are in the operating systems obviously Linux, and more recently in the database market, MySQL.

Third, interesting new markets are shaping up, such as the Embedded market. This could prove to be an ideal place for technologies such as object databases to bridge that gap between all these objects around and databases..

Funny enough, the gap between objects on one side and databases on the other side is still a problem, as it was several years ago. The important difference is that now million of objects have been deployed in a variety of production solutions and products around the world, not any more by a number of early adopters.

With this program I want to create a resource on the Web where researchers and developers can freely download technical information, teaching material and when possible software to help them in their work. Teaching at graduate or undergraduate level, conducting research, developing software for a commercial product, developing software for an open source project are all good examples of this.

This place is not exclusive, it is a shareable resource. I am honored that a number of friends and colleagues around the world have agreed to contribute to this project. They are all listed under the Expert Corners. A big thank you to all of them!

I also would like to thank our corporate sponsors for their support that made this project possible.

I wish you an enjoyable visit to ODBMS.ORG and I hope this will be useful for your work.

Best Regards

Roberto V. Zicari
