java - Parsing user data as text - no format in text -


my focus parse plain text, has information users, including browser, version, , operating systems each user used, , extract such information (browser/version, operating system/version....)

is there general frame work/libs (in java[preferred] or c++) has similar problem focus? believe each parsing problem may have different properties , need different approaches, if aware of any, please share or suggest, helpful clarifying steps of problem, , possibly avoiding repeated work or bugs or increasing effectiveness.

i found schema oracle text analysis, seems pretty interesting: (http://www.oracle.com/webfolder/technetwork/data-quality/edqhelp/content/processor_library/text_analysis/parse.htm)

the amount of input data can big, make question simple, can ignore largeness of data now.

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 ...
