opam - Difference between module and package Ocaml -


i'm trying follow stackoverflow answer located in post:

what best module httprequest in ocaml

and i'm running in problems. when trying run single file 

open lwt ;;

i getting , error saying unbound module. have run following opam instruction:

opam install lwt

and did install correct package.

so think problem difference between module , package, don't understand. looking @ question possible answer, wasn't sure if needed.

unbound modules in ocaml

thanks input guys, i'm new ocaml , i'm trying learn ins , outs of building something.

to use "package", must tell compiler explicitly. unbound module in ocaml means 1 of 2 things: made typo of module name, or failed set proper module search path. compiler options use?

if use ocamlfind, compilation should like:

ocamlfind ocamlc -package lwt -c mymodule.ml

this instructs compiler try find modules in lwt package installation directory, in addition default ones.

if not use ocamlfind.... well, use ocamlfind.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
