    that is increasingly awash in information Examples include respecting personal privacy in social networks sharing information among government agencies and drawing valid results from online databases We re aiming to create a World Wide Web that is Policy Aware where information is accompanied by rules that govern its use and where automated reasoners detect if the use of the data complies with the rules We use techniques from Linked Data Semantic Web automated reasoning and parsing rules Some particular challenges are 1 Expressing policies in machine readable form 2 Extracting and combining information from independent sources like your Facebook page your Flickr page and your Tweets 3 Building automated reasoners that continue working when rules and facts change and are even contradictory 3 Expressing real policies such as actual laws in ways that the information can be interpreted by machines If you d like to work on these kinds of research problems send email to Marisol and come talk to us We are interested in working with students at all levels UROP MEng or PhD Please see our current UROP opportunities New to DIG For students who ve just joined DIG we recommend that you do the following Get a CSAIL account if you don t already have one Speak to Marisol about your paperwork to find out where you should sit and to get added to relevant mailing lists Ask our senior students about how to access our code repositories Attend weekly DIG Seminar currently scheduled on Tuesdays from 11am 12pm Read the following papers The Semantic Web Tim Berners Lee Jim Hendler and Ora Lassila Scientific American 2001 Information Accountability Daniel Weitzner Hal Abelson Tim Berners Lee Joan Feigenbaum Jim Hendler and Gerald Sussman Communications of the ACM 2008 Access Control is an Inadequate Framework for Privacy Protection

    by building mobile apps In December 2010 Google introduced App Inventor for Android a visual programming environment that makes it easy to create apps for Android phones Prof Abelson who worked on App Inventor during his sabbatical last year is planning to include the system in a new course this fall He s looking for help in developing good examples and creating extensions to the system maybe even teaching summer workshops for kids To work on this project you should have some experience with Python 6 00 or 6 01 and an interest in mobile apps and educational technology For more information see MIT Center for Mobile Learning http mitmobilelearning org Online Data Integration Using Semantic Web technologies The Semantic Web is a powerful distributed model for publishing utilizing and extending information and is sometimes referred to as Web 3 0 The contents of online Semantic Web data sources can be mashed up i e queried and integrated on the fly to provide rich Web applications However the user or application developer still needs to know exactly what data is present in each source and needs to formulate queries carefully in order to get a reply When the content of a source changes mashups users cannot take advantage of it until the application developer becomes aware of this change and modifies the application query accordingly In order to allow users to dynamically explore this space by asking open ended queries we intend to use the federation paradigm from database systems where federated data sources collaboratively attempt to solve a user s query In this project the student will learn about and use Semantic Web technologies extend our existing federation protocol and implement a use case A successfully implemented project could lead to support and or an MEng in the Fall
