web parts - SharePoint-specific WebPart-class (instead of System.Web.UI) -


i started using sharepoint 2013. created project using built-in tools (office developer add-ons) sharepoint project.

i porting sharepoint 2010 project few webpart more or less file-by-file. old webparts made use of webpart class found in microsoft.sharepoint.webpartpages.webpart. according msdn, should exist in sharepoint 2013. however, not present (i compiler errors).

my question is: dll / using directive missing?

i tried using using microsoft.sharepoint.webpartpages (and inheriting webpart), still comes error (using works fine though).

i figured out. had set project sandboxed, disables features including specific webpart-type. re-creating project non-sandboxed project made work.

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 ...
