The Social Life of Personal Information

Dr. Manuel A. Perez-Quinones

Associate Professor of Computer Science

1:00pm Thursday 14 April 2011, ITE 325b

Personal Information Management (PIM) practices are the set of behaviors that we follow to organize our information. This often includes the management of email messages, documents, bookmarks, digital pictures, music, etc. Research in PIM has identified a core set of set of behaviors: encountering information, deciding to keep the information, filing/archiving, and reusing the information. The plethora of digital information and online transactions has us struggling to manage information effectively. In my research group, we are exploring how we can help address this problem.

In this talk, I briefly present previous work on PIM and highlight some new projects that my research group is exploring at the intersection of PIM and Social Networks. The rise of social networks presents an opportunity for the management of personal information. Emails in a person's inbox, for example, are "shared" between the sender and the receiver. What if we could share the PIM practices within our inner personal circle? Could we leverage the power of our social network to be more organized?

Lecture on Distributed Quantum Algorithms, 2:30pm Web 3/30

Classical computers use binary “bits” of ones and zeros. Quantum computers encode such bits in physical systems where we can also harness the quantum mechanical properties and obtain a more powerful system of quantum bits, or qubits. Thanks to the amazing rules of quantum mechanics, qubits can be in a “superposition” of zero and one simultaneously.

Professor Samuel Lomonaco will present a lecture on Distributed Quantum Algorithms from 2:30 to 3:45 on Wednesday March 30 in room ITE 325b. In the talk, Professor Lomonaco will show how quantum entanglement can be used as a mechanism for controlling a network of quantum computers. The talk is open to all.

Dissertation Defense

Enabling Reproducibility of Scientific Data Flows
through Tracking and Representation of Provenance

ITE 325b, UMBC

Reproducibility of results is a key tenet of science. Some modern scientific domains, such as Earth Science, have become computationally complicated and, particularly with the advent of higher resolution space based remote sensing platforms, tremendously data intensive. Over the last few decades, these complexities along with the the rapid advancement of the state of the art confound the goal of scientific transparency.

This thesis explores concepts of data identification, organization, equivalence and reproducibility for such data intensive scientific processing. It presents a conceptual model useful for describing and representing data provenance suitable for very precise data and processing identification. It presents algorithms for creating and maintaining precise dataset membership and provenance equivalence at various degrees of granularity and data aggregation.

Application of this model will allow more specific data citations in scientific literature based on large datasets and data provenance equivalence. Our provenance representations will enable independent reproducibility required by scientific transparency. Increasing transparency will contribute to understanding, and ultimately, credibility of scientific results.

2011 Google Summer of Code open for applications

The 2011 Google Summer of Code pays students $5000 to work on one of a set od approved open source projects

Still looking for a summer internship? Check out the Google Summer of Code (GSoC).

This is a is a global program funded by Google that pays undergraduate or graduate students a $5000 stipend to write code for open source projects. GSoC has worked with the open source community to identify and fund exciting projects for the upcoming summer. The FAQ is a good place to find out more.

A set of open source projects (aka mentoring organizations) has been selected. Students apply to work on one of more of these and each mentoring organization ranks the students interested in working with them. Google facilitates the final selection and pairing. The mentoring organization works closely with the student to define tasks, check progress, help solve problems, etc. Typically the thudent works remotely, interacting with his or her mentor via email, chat, skype, etc.

Students can submit applications via the Google Summer of Code 2011 site from March 28 to April 8. Google says that that the best applications they receive are from students who took the time to interact with one of the participating mentoring organizations and discuss their ideas before submitting an application. Check out the information on the Advice for GSoC Students Page which links to a list of the 2011 mentoring organizations.

I have a plug for a particular project: Elgg. "Elgg is an award-winning social networking engine, delivering the building blocks that enable businesses, schools, universities and associations to create their own fully-featured social networks and applications." One of the people involved with Elgg's GSoC effort works at JHU/APL and may do mentoring locally. They are looking for people who know (or are willing to learn) PHP, JavaScript, and basic web development. Send email to to find out more about the ideas the Elgg project has proposed for GSCO 2011.

UMBC defends title in Final Four of College Chess

UMBC will field the same team that won the 2010 Final Four of College Chess seen in this photo from their 2010 win.

Next weekend UMBC will defend its title of best college chess team in the United States at the Final Four of College Chess. The match will be held on 1-3 April at Booz Allen Hamilton's corporate site in Herndon, VA.

Each year, the top four USA schools from the Pan American Intercollegiate Team Chess Championship are invited to compete for the President's Cup in a match that has come to be known as the "Final Four of College Chess". The winner is considered to be the top US college chess team.

This year, the UMBC team will face three teams from Texas universities: Texas Tech University, the University of Texas at Dallas, and the University of Texas at Brownsville.

Director of the UMBC Chess Program, Professor Alan Sherman, believes that UMBC has the strongest team but says "We are fielding the same team that won the Final Four last year and that placed second in the 2010 Pan-Am in Milwaukee. It will be a close fight in which any of the four teams could possibly win."

UMBC's team consists of International Grandmasters Leonid “Chief” Kritz, Sergey “The Stealth” Erenburg, Giorgi Margvelashvili, International Master Sasha “Plaplan” Kaplan and International Woman Grandmaster Sabina "Sunshine" Foisor (alternate). Supporting the team are UMBC Chess Coach Igor Epshteyn and Associate Chess Director Sam Palatnik.

Update 4/1:  The Final Four program is now available. See the UMBC news item.

SELinux Talk and Tutorial

David Quigley
Advanced Engineering & Development, Keyw Corporation

4:00pm Friday, 1 April 2011
Room 229 ITE, UMBC

Over a decade ago researchers at the National Information Assurance Research Lab at the NSA identified a need for flexible mandatory access controls to help provide a solid foundation for secure systems. This resulted in the development of the FLASK architecture, which has seen implementation in a number of operating systems. The most prominent implementation of FLASK is in the form of SELinux. Since the early days of SELinux adoption much work as been done to improve the utility and usability of SELinux. These enhancement have turned SELinux from a prototype research implementation into a robust access control mechanism that is used by a variety of customers world wide.

This talk is a from the ground up journey through SELinux. It starts with why do we need this technology and then moves through where to obtain it, how it works, and how to identify and solve problems associated with SELinux. In addition to these basics the talk also covers slightly more advanced topics such as hot to construct policy for new applications and hot to address customizations particular to your deployments.

David Quigley started his career as a Computer Systems Researcher for the National Information Assurance Research Lab at the NSA where he worked as a member of the SELinux team but has since left that position. David leads the design and implementation efforts to provide Labeled-NFS support for SELinux. David has previously contributed to the open source community through maintaining the Unionfs 1.0 code base and through code contributions to various other projects. David has presented at conferences such as the Ottawa Linux Symposium, the StorageSS workshop, LinuxCon and several local Linux User Group meetings where presentation topics have included storage, file systems, and security. David currently works as a Computer Science Professional for the Advanced Engineering and Development division at Keyw Corporation.

This talk is sponsored by the UMBC Linux Users' Group.

Making smartphones more intelligent

Mobile devices will provide better services if then can model, recognize and adapt to their users' context.

Our smartphones are quite capable, but not really very intelligent. They have more computational power than the supercomputers NASA used to reach the moon and are loaded with sensors, but lack "situational awareness" — an ability to understand their context and use that knowledge to provide better services for their users.

CSEE professor Tim Finin is one of the organizers of a workshop on Activity Context Representation: Techniques and Languages that is focused on the problems underlying making mobile devices more intelligent. The workshop will address techniques and systems to allow mobile devices model, reason about, and recognize the activities and context of their users and exploit those models to provide better services. The workshop is sponsored by the sponsored by the Association for the Advancement of Artificial Intelligence and will be held on August 7th and 8th in San Francisco as part of AAAI-11, the Twenty-Fifth Conference on Artificial Intelligence.

Finin is working with colleagues Anupam Joshi and Laura Zavala and students from the ebiquity lab on the NSF-sponsored Platys project that is working on this problem. The project is developing software for Android phones that uses machine learning algorithms to recognize their users' activities and their roles in them and selectively share this information with other devices based on user-defined privacy policies.
