The TREC spam filter submission page is now ready: trec.nist.gov/act_part/forms/results.forms.html For "run identification" please enter a string constructed using the following convention: gggtnF ggg is a group identifier t is the task (S = spam filter A = active) n is the priority of the submission (1-4) F means Filter (filter submission) The spam filter submission itself should be a single .tgz or .zip file containing "initialize" "train" "classify" and "finalize" as described in the guidelines. The active filter submission should be a .tgz or .zip file containing "active.cpp" NIST have created a Perl script that you may use to check that your .zip or .tgz file includes these files; see http://trec.nist.gov/act_part/tools.html --- RESULTS SUBMISSION Later, there will be a similar "spam results" submission page. For that page please use a "run identification" following this convention: gggtnddd gggtn is the same as for the filter used to generate the result ddd identifies the public corpus to which the filter was applied; one of: pci (public chinese immediate feedback) pcd (public chinese delayed feedback) pei (public english immediate feedback) ped (public english delayed feedback)
