google app engine - POS tagging on GAE -

-

i trying part of string tagging pull out nouns of sentence in python on google app engine. far have tried use nltk library. unable nltk working in gae. error message complains missing numpy module.

this person has had same problem: https://groups.google.com/forum/?fromgroups#!topic/nltk-users/2nwztlgfyvi

i cannot find clear instructions on how nltk running on gae or alternative pos tagger runs on gae

edit:

my steps trying nltk working (i'm on osx 10.7):

  1. install nltk via terminal "easy_install nltk"
  2. copy nltk root of appengine project /library/python/2.7/site-packages/nltk-2.0.1-py2.7.egg/nltk/

  3. add following settings app.yaml:

    runtime: python27 threadsafe: false  libraries:   name: numpy   version: "latest"

  4. write test.py import nltk in it

  5. deploy, run , following error (the numpy error solved, new one):

the following nltk/data.py (around line 75):

###################################################################### # search path ######################################################################  path = [] """a list of directories nltk data package might reside. these directories checked in order when looking resource in data package.  note allows users substitute in own versions of resources, if have them (e.g., in home directory under ~/nltk_data)."""  # user-specified locations: path += [d d in os.environ.get('nltk_data', '').split(os.pathsep) if d] if os.path.expanduser('~/') != '~/': path += [ os.path.expanduser('~/nltk_data')]  # common locations on windows: if sys.platform.startswith('win'): path += [ r'c:\nltk_data', r'd:\nltk_data', r'e:\nltk_data', os.path.join(sys.prefix, 'nltk_data'), os.path.join(sys.prefix, 'lib', 'nltk_data'), os.path.join(os.environ.get('appdata', 'c:\\'), 'nltk_data')]  # common locations on unix & os x: else: path += [ '/usr/share/nltk_data', '/usr/local/share/nltk_data', '/usr/lib/nltk_data', '/usr/local/lib/nltk_data']

gae python27 supports numpy 1.6.1. specifying

runtime: python27

in app.yaml? link gave pre-dates python 2.7 support, i'm guessing not.

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
