    What is Your Software Worth? © Gio Wiederhold Stanford University April 2007 A shorter version of this paper was published in the Comm. of the ACM, Vol. 49 No.9, Sep. 2006 [Wiederhold:06]. Abstract This article presents a method for valuing software, based on the income that use of that software is expected to generate in the future. It applies well known principles of intellectual property (IP) valuation, sales expectations, software maintenance, product growth, discounting to present value, and the like, always focusing on the specific issues that arise when the benefits of software are to be analyzed. An issue, not dealt with in the literature of valuing intangibles, is that software is continually upgraded. Applying depreciation schedules is the simple solution, but depreciation is taken by purchasers, and does not represent the actual diminution of the inherent IP of software at the supplier. A novel approach, which considers ongoing maintenance and its effects, is presented here. All steps of the process are presented and then integrated via a simple quantitative example. Having a quantitative model on a spreadsheet allows exploration of alternatives. As an example we evaluate a service business model alternative. Some conclusions are drawn that reflect on academic and business practice. 1. Introduction. There exists a voluminous literature on estimation of the cost of producing software, but that literature largely ignores the benefits of using that software [Boehm:81, 00]. Even software engineering management approaches termed `Earned Value Management' only deal with expenses within a development schedule [Abba:97]. While we, as software creators, believe that what we produce is valuable, we are rarely called upon to quantify its benefits [GarmusH:01].

  • Simplicity: Semantics-Sensitive Integrated Matching for Picture Libraries
    IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE, VOL. 23, NO. 9, SEPTEMBER 2001 1 SIMPLIcity: Semantics-Sensitive Integrated Matching for Picture LIbraries James Z. Wang, Member, IEEE,JiaLi,Member, IEEE, and Gio Wiederhold, Fellow, IEEE AbstractÐThe need for efficient content-based image retrieval has increased tremendously in many application areas such as biomedicine, military, commerce, education, and Web image classification and searching. We present here SIMPLIcity (Semantics- sensitive Integrated Matching for Picture LIbraries), an image retrieval system, which uses semantics classification methods, a wavelet-based approach for feature extraction, and integrated region matching based upon image segmentation. As in other region- based retrieval systems, an image is represented by a set of regions, roughly corresponding to objects, which are characterized by color, texture, shape, and location. The system classifies images into semantic categories, such as textured-nontextured, graph- photograph. Potentially, the categorization enhances retrieval by permitting semantically-adaptive searching methods and narrowing down the searching range in a database. A measure for the overall similarity between images is developed using a region-matching scheme that integrates properties of all the regions in the images. Compared with retrieval based on individual regions, the overall similarity approach 1) reduces the adverse effect of inaccurate segmentation, 2) helps to clarify the semantics of a particular region, and 3) enables a simple querying interface for region-based image retrieval systems. The application of SIMPLIcity to several databases, including a database of about 200,000 general-purpose images, has demonstrated that our system performs significantly better and faster than existing ones. The system is fairly robust to image alterations.

  • Intellectual Capital: Software Innovation and Its Role in National Economies
    Intellectual Capital: Software innovation and its role in national economies Gio Wiederhold Stanford University, Stanford CA http://i.stanford.edu/~gio 5/29/2016 Gio Wiederhold Germany 2016 1 Abstract Software has invaded all aspects of our world. It can no longer just be viewed as a fascinating technology. Software, and the products that depend on it, from watches to aircraft, social interactions, and sharing services, comprise a large fraction of modern commerce. The creators and the intellectual property they generate, exploit, and maintain comprise the intellectual capital of our hidh-technology industry, an asset that competes with the financial capital that traditional manufacturing industries rely on. I will present the flow of innovation into our national economics. Rights to profit from intellectual property are poorly documented and are easily transferred among countries. The importance of our intellectual capital is underestimated by economists and planners because the `Big Data’ they access is primarily from financial-oriented sources. As result, governmental policies to improve economic activity and the welfare of its people are often naïve and sometimes wrong. In this world computing experts have roles beyond the base technology. 5/29/2016 Gio Wiederhold Germany 2016 2 Gio’s Bio Gio Wiederhold was born in Italy, educated in Germany and The Netherlands, moving to the US in 1958.

    COPA Testimony, Gio Wiederhold, August 2000 Testimony Prepared for the COPA (Child Online Protection Act ) Commission Gio Wiederhold Professor Computer Science Dept. and Dept.of Medicine, Stanford University www-db.stanford.edu/people/gio.html Technology demo by James Wang (PhD summer 2000) As of fall 2000 at Pennsylvania State University http://jxw.stanford.edu/cgi-bin/zwang/wipe2_show.cgi August 2000 Thank you for the privilege of presenting some statements concerning the technology relevant to the protection of minors before this commission. I will not attempt to present the full range of technological choices, threats, and candidate solutions. Instead I will focus on two points, one being specific technology in image recognition (WIPE) that we have developed at Stanford, and, second, some systematic setting of the issues in a producer-transmitter-consumer framework, which will illustrate requirements and barriers to technological solutions. I will actually start with the second aspect, but close with some suggestions for managing the system issues. Dealing with the system chain To deal effectively with any problem we have to consider complete systems and the feedback loops that enable their functioning. Applying corrections or constraints at isolated points will just cause systems that are in some sense stable, to adapt. We have to consider here the entire chain of flow from Producers via Transmitters to Consumers. In each of these categories exist a variety of groups, with different means and objectives. We often hear complaints that some technology will not solve the whole problem, but such an observation, even though nearly always true, does not mean that it cannot be applied to affect the system in some focused and desirable way.

Nobel Laureate Economist Herbert A. Simon. Acknowledgement The main results of this thesis were obtained during my time at the Institute AIFB at the University of Karlsruhe, Germany. I would like to express my gratitude to my advisor, Prof. Dr. Rudi Studer, for his support, patience, and encouragement throughout my graduate studies. It is not often that one finds an advisor and colleague who always finds the time for listening to the little problems and roadblocks that unavoidably crop up in the course of performing research. I am also grateful to Prof. Dr. Peter Knauth and Prof. Gio Wiederhold who were willing to serve on my dissertation committee on a very short notice, and to Prof. Dr. Wolfried Stucky and Prof. Dr. Andreas Geyer-Schulz, who served on the examination committee. My thanks also go to all the colleagues at the Institute AIFB - in particular to Dr. Michael Erdmann - together we worked on the nitty-gritty details of the Ontobroker architecture, and Michael helped me to shape my ideas about the future of the Web.

  • Surajit Chaudhuri Speaks
    Surajit Chaudhuri Speaks Out on How Data Mining Led Him to Self-tuning Databases, How He Does Tech Transfer, Life as a Research Manager, the Fragmentation of Database Research, and More by Marianne Winslett http://research.microsoft.com/~surajitc/ Welcome to this installment of ACM SIGMOD Record’s series of interviews with distinguished members of the database community. I’m Marianne Winslett, and today we are in Istanbul, site of the ICDE 2007 conference. I have here with me Surajit Chaudhuri, who is a research area manager at Microsoft Research. Surajit’s current research interests lie in self-tuning databases, data cleaning, and text. Surajit is an ACM Fellow, and he received the SIGMOD Contributions Award in 2004. His PhD is from Stanford. So, Surajit, welcome! Surajit, your PhD work was in database theory, then you switched to query optimization, then to self-tuning database systems. What has led you to become more practical over the years? When I started at Stanford in database theory, I really liked everything I learned as a student of initially Gio Wiederhold, and then Jeff Ullman. It was a very educational experience, but I realized that I was not going to be as good as Jeff Ullman or Moshe Vardi as a database theoretician. So I started looking at more practical problems, and when I joined HP my job also demanded that. Slowly I migrated more towards systems work. I think that was good, because I don’t think I am as smart as the database theoreticians! That’s very flattering to the database theoreticians.

  • Interview with Jeff Ullman
    Gio Wiederhold Speaks Out on Moving into Academia in Mid-Career, How to Be an Effective Consultant, Why You Should Be a Program Manager at a Funding Agency, the Need for Ontology Algebra and Simulations, and More by Marianne Winslett Gio Wiederhold http://www-db.stanford.edu/people/gio.html Welcome to the second installment in the SIGMOD Record’s series of interviews with pillars of the database community. In the last issue we heard from Jeff Ullman, and upcoming issues will include conversations with David DeWitt, Avi Silberschatz, and Hector Garcia-Molina. This issue’s interview with Gio Wiederhold took place in June 2001, a few days before the festivities associated with Gio’s retirement from Stanford University. Gio has been a member of the Stanford faculty for many years, active both in computer science and in medical informatics. In the late 1980s, Gio also spent several years as a program manager at DARPA, focusing on middleware and mediators. Gio is an ACM Fellow, an IEEE Fellow and Golden Core Member, a Fellow of the American College of Medical Informatics, a recipient of the SIGMOD Contributions Award, and a past editor-in-chief of ACM Transactions on Database Systems, among many other distinguished positions. Gio has had a varied and fascinating career, and it is tempting to slip into a series of anecdotes about adventures Gio has had on the job in nations around the world. But instead, I suggest that you ask him about his adventures yourself the next time you see him on the road. Gio loves a lively story and a fun time.

  • Mediators, Concepts and Practice Gio Wiederhold
    Mediators, Concepts and Practice To appear in Studies Information Reuse and Integration In Academia And Industry Springer Verlag, Wien, 2012 Editors: Tansel Özyer, Keivan Kianmehr, Mehmet Tan, Jia Zeng Gio Wiederhold Prof. Emeritus, CS, EE, & Medicine, Stanford University [email protected] 0 Abstract Mediators are intermediary modules in large-scale information systems that link multiple sources of information to applications. They provide a means for integrating the application of encoded knowledge into information systems. Mediated systems compose autonomous data and information services, permitting growth and enable their survival in a semantically diverse and rapidly changing world. Constraints of scope are placed on mediators to assure effective and maintainable composed systems. Modularity in mediated architectures is not only a goal, but also enables the goal to be reached. Mediators focus on semantic matching, while middleware provides the essential syntactic and formatting interfaces. 1 Overview We first present the role of mediators and the architecture of mediated systems, as well as some definition for terms used throughout this exposition. Section 3 deals with mediators at a conceptual level. Section 4 presents the basic functionalities, and Section 5 presents the primary objective of mediators, information integration, including the problems of heterogeneous semantics, and the modeling of knowledge to drive integration. Section 6 points to related topics, not covered as such in earlier chapters. A final summary reviews the state of the technology, indicating where research is needed so that the concepts will support composed information systems of ever greater scale. 1.1 Architecture Mediators interpose integration and abstraction services in large-scale information systems to support applications used by decision-makers, where the scale, diversity, and complexity, of relevant data and information resources are such that the applications would be overwhelmed.
