Peter Norvig on Applying Machine Learning to Programs at OpenSym 2015

Peter Norvig of Google Research, will be presenting the following keynote at OpenSym 2015:

Title: Applying Machine Learning to Programs

Abstract: Certain tasks, such as recognizing speech, or correcting spelling errors, are now routinely handled with machine learning algorithms. But most tasks are handled the old fashioned way, with programmers writing code line by line. Machine learning algorithms work by amassing large numbers of examples and extracting patterns from them. We certainly have amassed a large number of examples of code; what can algorithms, and we, learn from them?

Biography: Peter Norvig is a Director of Research at Google Inc. Previously he was head of Google’s core search algorithms group, and of NASA Ames’s Computational Sciences Division, making him NASA’s senior computer scientist. He received the NASA Exceptional Achievement Award in 2001. He has taught at the University of Southern California and the University of California at Berkeley, from which he received a Ph.D. in 1986 and the distinguished alumni award in 2006. He was co-teacher of an Artifical Intelligence class that signed up 160,000 students, helping to kick off the current round of massive open online classes. His publications include the books Artificial Intelligence: A Modern Approach (the leading textbook in the field), Paradigms of AI Programming: Case Studies in Common Lisp, Verbmobil: A Translation System for Face-to-Face Dialog, and Intelligent Help Systems for UNIX. He is also the author of the Gettysburg Powerpoint Presentation and the world’s longest palindromic sentence. He is a fellow of the AAAI, ACM, California Academy of Science and American Academy of Arts & Sciences.

Robert J. Glushko on Collaborative Authoring, Evolution, and Personalization for a “Transdisciplinary” Textbook at OpenSym 2015

Robert J. Glushko of University of California, Berkeley, will be presenting the following keynote at OpenSym 2015:

Title: Collaborative Authoring, Evolution, and Personalization for a “Transdisciplinary” Textbook

Abstract: This presentation is a case study about a book titled The Discipline of Organizing, which proposes a transdisciplinary synthesis of ideas from library and information science, computer science, informatics, cognitive science, business, and other disciplines that “intentionally arrange collections of resources to enable interactions with them.” This case study discusses the interrelationships between the transdisciplinary goal for the book, the process of collaborative authoring required to write it, the novel architecture of the book’s content, and the innovative reading experiences in print and ebook formats that are enabled. The idea that abstract concepts and methods of organizing define a new discipline that is contextualized by more specific concepts and methods inevitably led to a collaboratively-authored book whose design embodies this intellectual architecture. The book’s content is organized as a transdisciplinary core with supplemental content identified by discipline. This content model creates a “family of books” with thousands of siblings, any of which can be published in print or as an ebook by filtering on the disciplinary attributes. This “design-time” customization was enhanced to enable “reading-time” personalization for ebook formats. In addition, the rich semantic markup that enables customization and personalization is fodder for further experimentation about “smart textbooks” that can be continuously made smarter by dynamic discovery and inclusion of content.

Biography: Robert J. Glushko is an Adjunct Full Professor in the School of Information at the University of California, Berkeley. After receiving his PhD in Cognitive Psychology at UC San Diego in 1979, he spent about ten years working in corporate R&D, about ten years as a Silicon Valley entrepreneur, and now has worked over ten years as an academic. His interests and expertise include information systems and service design, content management, and ebook design and publishing. He founded or co-founded four companies, including Veo Systems in 1997, which pioneered the use of XML for electronic business before its acquisition by Commerce One in 1999. He is a co-author of Document Engineering: Analyzing and Designing Documents for Business Informatics and Web Services, published in 2005. More recently, he is the principal author and editor of The Discipline of Organizing, named an “information science book of the year” in 2014 by the Association of Information Science and Technology.

Richard P. Gabriel on Artificial Sentiment: Using Machines to Manage Public Sentiment on Social Media at OpenSym 2015

Richard P. Gabriel, renowned research scientist at IBM’s Watson Group, will be presenting the following keynote at OpenSym 2015:

Title: Artificial Sentiment: using machines to manage public sentiment on social media

Abstract: Social media is where public opinion is happening: where it’s born, where it grows / matures, and where it dies. In this talk I review techniques and approaches for machine processing of public sentiment on social media: how to analyze and understand it, how to react to it, and how to influence it. The age of artificial intelligence is upon us.

OpenSym seeks to accommodate the needs of the different research disciplines it draws on. Authors whose submissions have been accepted for presentation at the conference have a choice of having

  • their paper become part of the official proceedings, archived in the ACM Digital Library, or having
  • only a short abstract included in the proceedings (rather than the full submitted paper) in order to preserve future publication possibilities.

Doctoral Symposium Call for Submissions

OpenSym seeks to explore the synergies between all strands of open collaboration research. Thus, we will have a doctoral symposium, in which Ph.D. students from different disciplines can present their work and receive feedback from senior faculty and their peers.

Submission deadline for doctoral symposium position papers is May 3rd, 2015.

Authors submit through EasyChair at Submissions and final contributions must follow the ACM SIG Proceedings template found at

The Doctoral Symposium is chaired by Andreea Gorbatai of University of California at Berkeley. More information is available at

Industry and Community Track Call for Submissions

OpenSym is also seeking submissions for experience reports (full and short), tutorials, workshops, panels, non-research posters, and demos. Such work accepted for presentation or performance at the conference is considered part of the industry and community track. It will be put into the proceedings in an industry and community track section; authors can opt-out of the publication, as with research papers, but will still have to provide an abstract (less than one page) for the proceedings.

Submission deadline for industry and community track papers is April 19, 2015.

Authors submit through EasyChair at Submissions and final contributions must follow the ACM SIG Proceedings template found at
