Module 2: Monday September 8 to Sunday September 14

This module takes us through the process of getting from a collection of text documents to the inverted index that we will use in the next module as a basis for ranked retrieval. The module is designed to be completed in 12 hours over 7 days. As with every module, you must complete all components of this module by midnight on the evening of the indicated end date for the module (in this case, Sunday, September 14).

This week we have three reading assignments.

Summaries of Additional Readings

Additional readings are assigned to five students. All students should read the five summaries once they are posted to ELMS, and all students other than those who wrote a summary this week should make a comment on the discussion board about at least one of the summaries (or about someone else's comment on one of them).


Here are the videos for this module:

Exercise E2

Finally, complete Exercise E2. Like all assignments that you are asked to turn in, this is due at midnight on the last day of the module (which is always a Sunday night). Note that you are allowed to work with other students on exercises, but you must type in the results yourself (no cut and paste -- see the course description for details).
