Assumed Background

Students are expected to have Java programming expertise and knowledge of computer systems, data structures, and algorithms commensurate with completion of CS211.  

Course Structure and Student Responsibilities

Lectures

I try to make my lecture style as interactive as possible. My goal is to engage students in the lecture process and encourage questions and comments. At times I will spontaneously ask for input, thinking, and opinions from students in lecture. You should come to lecture prepared to think about the materials presented and how they relate to the overall course content and readings, and recognize that your role in lecture is a reflection of your overall scholarly attitude towards the course.

Readings

The subject of the course is a dynamic area. Most of the material in the course is the result of recent research and implementation. Fortunately almost all of this work is available through papers on the open-source Web. Readings are assigned for each week's discussion section are listed in the reading schedule.

At a minimum, students are supposed to read the readings.   To provide the incentive for doing this, I've tried to make the readings sufficiently interesting and informative.  As an extra incentive, students will need to complete a short set of questions about the readings.  The questions will be available every Wednesday evening and will be due before the next section meeting on Friday.  The questions will be short, designed to make sure that the assigned papers have been read. These questions will be graded.

Discussion Section  

Beyond just looking at the readings, students are expected to approach each week's readings critically and understand how they compliment, or perhaps disagree, with lecture content. Are the ideas sound? What are the alternatives and trade-offs? How well do the ideas fit into the larger information context? What are the barriers to success: technical, social, legal, and economic.

Weekly sections are meant to be a forum for discussing these critical reactions, driven by student participation and NOT by instructor or teaching assistant presentations. The amount of section participation and the degree to which it represents critical and content-based thinking is an important criteria of grading.

Reaction Papers

Reaction papers are another vehicle for integrating information from readings and lectures. Each paper is a critical evaluation of two papers, one of which is chosen from assigned readings and another chosen at the discretion of the student. Reaction papers are due every three weeks.  The tentative reaction paper due dates are February 10, March 3, March 31, April 21, and May 12 at 11:59PM.

More details  about reaction papers are given on the readings page.

Programming Projects

Work in the area of web information systems requires the ability to understand and use protocols, markup languages, and integrate tools.  The course projects provide students with the opportunity to gain expertise in these areas. Students will work in groups of 2. Grades will be awarded based on the final product of the group and each student's contribution to the work of the group.  The tentative project due dates are April 3 and May 15 at 11:59PM.

Project details are available on the assignments page.

Books

All required readings are available on the Web.  The project assignments require use of XML and related tools. Sudents don't have to buy any books, because there are considerable sources of information on the Web. However, a real book is sometimes a help and here are some suggestions (all available from Amazon):

Grading

Final course grades will be based on project assignments,  reaction papers, and scholarly attitude.  The last criteria is a combination of participation, attendance, and conscientiousness (taking the time to complete the weekly questionnaires is one demonstration of this) .  The weightings given to these components are roughly as follows:

An excellent student, deserving an "A", is one who excels in all three areas

Course E-mail

Students are responsible for keeping track of all course e-email.  Every message sent will have the prefix "CS/INFO 431:" on the subject line.  Make sure that your spam filter is configured to let course e-mail through.

Similarly, all mail to the instructor and TA should have the prefix "CS/INFO 431:" on the subject line.  Mail not sent with that prefix may be lost in spam, endless lists, etc.

Feedback Responsibility

Like any Cornell course, the goal of CS431 is to provide the context for students to learn about a subject area that the instructor finds relevant and interesting. Students should expect that the course meets their expectations, is stimulating, and worthy of their time. I hope to convince many of you that you might want to engage in future work in this area. It is your responsibility to tell me if the course fails to meet these expectations - your feedback is necessary to making this semester successful.
