i working on document recommendation program , kinda stuck here. each document, have score assigned according user's actions. then, when new document comes in, need predict how user , rerank whole documents again according scores. solution use threshold divide scores "recommend" , "not recommend". naivebayes or other classification models can either give me label or return possibility of label (i using nltk package text analytics). on right way? question when possibility, how can convert score use ranking? or should use logistic regression in scikit instead? thanks! i suggest trying out svm-rank algorithm. takes input set of "recommended" , "not recommended" vectors , learns how rank them recommended ones come first. there simple python tool in dlib can use it. see here example: http://dlib.net/svm_rank.py.html

the target application can used in "pipe" mode, means accepts input stdin, , can output stdout. however, there risk of user making mistake, directing output stdout, without directing stdout towards "something" (a file, or consumer program). consequence, console screen gets garbaged displaying binary data (since default, stdout outputs screen). bottom line : want avoid binary output displayed console, automatically. must done in portable c , , not depend on external script. a few potential ways of doing : 1) possible detect stdout going console, in order redirect somewhere else instead ? (including /dev/nul). note code must portable, , work windows , linux (and bsd, opensolaris, etc.) 2) alternative : possible redirect stdout "somewhere else" (such /dev/nul) default without harming correct usage of program, redirecting stdout valid consumer process ? on posix (e.g. linux , osx) system can use isatty function check if stdout goes co...
