Implementing incremental search in emacs -


i improve emacs-eclim , add incremental search through java types in edited project (shift-ctrl-h in eclipse).

i can call eclim-java-find variants results in *eclim: find buffer.

but here comes question:

how 1 implement behaviour lets user type minibuffer (with prompt) , calls other function on each minibuffer change (new/deleted character) current minibuffer content argument or other way of accessing current search string.

you can add function post-command-hook, example. called after every command (typing character command: self-insert-command). function can check minibuffer contents function minibuffer-contents.

just don't forget remove function post-command-hook when search command finished. can use minibuffer-setup-hook , minibuffer-exit-hook control attaching function.

just don't forget remove attaching function minibuffer-setup-hook/minibuffer-exit-hook either when search command finished. :)

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 ...
