11/11/2019 Boolean Retrieval: FAQ 1/2 Search Engines: 11-442 / 11-642 HW1 Frequently Asked Questions Index Test Cases and Grading Miscellaneous Index Question: What is an md5 checksum and how do I create one? Answer: md5 checksums are used to verify that a file has been downloaded correctly without corruption. To generate them, on a linux machine use the md5sum command. On Windows, try this utility . On Mac, use the md5 command from the terminal. Question: Is there a way to know more about what is in the index? It might help us debug our software. Answer: The QryEval zip and tgz files contain a simple InspectIndex utility that we use to examine index contents when we are developing our code. Use the same -classpath settings that you use for the example QryEval software. If you run it with no commandline arguments, it will print a usage messsage that tells you what parameters it takes. Test Cases and Grading Question: Is there a script to help me download the development ("Training") test cases for HW1? Answer: The TA's provided an example script for Linux people. Note that it isn't necessary for you to download all of the development test cases. You can uses the HW Testing Service if you prefer. However, it may be faster to compare your results to local copies of the gold standard results, especially when the web servers are busy. Question: I'm having trouble getting trec_eval to accept my result file. Answer: See a small working example . Download it and try it. If it works, the problem is your file, not the trec_eval program.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
