  5. Course Rules • Unless special permission is obtained from the instructor, each student will work individually • Copying material from other sources will not be permitted unless the source is properly referenced • Any student who plagiarizes from other sources will be reported to the Computer Science department and any other committees as advices by the department • No copying of anything from a paper except for about 10 words in quotes. No copying of figure even if its attributed. You have to draw all figures.

  6. Course Plan • 4 assignments 8 points each # 1 Given Feb 1, Due Feb 15 – Due Feb 17 – Returned #2 Given Feb 15, Due March 1 – Due March 8 - Returned #3 Given March1, Due March 29 – Given March 10 – due March 31 #4 March 29 Due April 12 – Given March 31, Due April 14 • Two exams – 16 points each Exam #1: March 3 or March 10 – March 10 – will return March 31 - returned Exam #2: May 3 or May 10 – May 10 • 2 term papers – 10 points each • #1: Due March 3 or March 10 (depending on exam) - Returned • #2: April 19 • Programming project: 16 points April 26 • Total 100 points

  7. Contact • For more information please contact • Dr. Bhavani Thuraisingham • Professor of Computer Science and • Director of Cyber Security Research Center Erik Jonsson School of Engineering and Computer Science EC31, The University of Texas at Dallas Richardson, TX 75080 • Phone: 972-883-4738 • Fax: 972-883-2399 • Email: bhavani.thuraisingham@utdallas.edu • URL: • http://www.cs.utdallas.edu/people/thuraisingham.html

  8. Project • CD-ROM - your software • Hard copy – design document • Project description • Architecture (prefer with a picture) and description (software – e.g., Oracle, Jena etc.) • Results • Analysis • Potential improvements • References

  9. Paper: Original – you can use material from sources, reword (redraw) and give reference • Abstract • Introduction • Body of the paper • Comparing different approaches and analyzing • Discuss your approach, • Survey • Conclusions • References • ([1]. [2], - - -[THUR99]. • Embed the reference also within the text. • E.g., Tim Berners Lee has defined the semantic web to be -- -- [2].

  10. Review for the Exam #1 – March 10, 2010 • NVD database – use of semantic technologies • Confidentiality, privacy and trust and applied to semantic web • Secure third party publishing of XML documents • Inference problem and semantic web • RDF and Security • OWL and Security • Ontology alignment and security • ROWLBAC – question on paper • Platform for privacy preferences • Assured information sharing • Web Services and Security • SAML, XACML • Extra credit question

  11. Policy for Second Half of the Semester • Because this is a PhD level class, during the second half, the students will be reading papers and presenting in class. • Students will read all the papers assigned; the paper will be posted in the Introduction section on the Monday prior to the following week (e.g., March 22 for lectures on March 29 and March 31) • One or more students will be selected at random and requested to present the paper and the entire class will participate • While it is unlikely that a student will be selected twice, it is not improbable • If a student is absent without a valid excuse prior to the class (e.g., a student is sick) 5 points will be deducted from the final score if a student is not present to present the paper.

  12. Papers for March 29 and March 31 • http://www.mindswap.org/papers/Trust.pdf • Trust Networks on the Semantic Web. Jennifer Golbeck, James Hendler, Bijan Parsia, WWW 2003. - Describes a web-of-trust/reputation system based on FOAF profiles and explicite ratings and proposes the use of network analysis to make trust recommendations based on implicite ratings. • http://groups.csail.mit.edu/dig/Rein/rein-paper.pdf • Rein Policy Framework for the Semantic Web. Decentralized framework for representing and reasoning over distributed policies in the Semantic Web using Rei and CWM. Lalana Kagal and Tim Berners-Lee.
