json - Python Dictionary key index issue (possibly scope?) -


i've run strange issue when pulling text json response querying twitter api.

if pull text in manner: 

def retrievetext(raw_tweets):     l in raw_tweets:        format_data = json.loads(l)          k in format_data.keys():            if k == 'text':                text = format_data['text']

i not have issues. however, bit cumbersome iterate on list of keys.

if change version:

def retrievetext(raw_tweets):     l in raw_tweets:         format_data = json.loads(l)         text = format_data['text']

i receive keyerror, not make sense me based on results of previous code snippet.

if has insight on overlooking, please let me know.

this

for k in format_data.keys():     if k == 'text':         text = format_data['text']

could rewritten as:

if 'text' in format_data:     text = format_data['text']

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 ...
