python - How to filter Haystack SearchQuerySets by related models -


how filter/join haystack searchqueryset related model fields?

i have query like:

sqs = searchqueryset().models(models.person)

and returns same results equivalent admin page returns.

however, if try , filter model records linked foreign key:

sqs = sqs.filter(workplace__role__name='teacher')

it returns nothing, though page /admin/myapp/person/?workplace__role__name=teacher returns several records.

i don't want full-text searching of these related models. want simple exact-match filter. possible haystack?

you cannot perform joins using search engine ones supported haystack. make queries need add information want filter on in "denormalized" fashion in search index:

class profileindex(indexes.searchindex, indexes.indexable):     # other fields, model attributes     role_name = indexes.charfield()      def get_model(self):         return person      def prepare_role_name(self, person):         return person.workplace.role_name

then can filter on field role_name. make sure update index if eg. name changes, have update according entries in search index.

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 ...
