I added examples for showRequest() and showResponse(). In my case, I return some xml in upload() containing a status value which is parsed in showResponse(). You are correct that you need to add url patterns in urls.py for upload(), get_upload_progress() and the upload form. I build the upload form using javascript and display it as a dialog box to avoid page navigation so I don't have a form url. Regarding handling multiple files, HttpRequest.FILES in Django contains the list of files posted. upload() should be modified to handle multiple files. The rest can stay the same. @Josh.

I'm trying to implement this (just a test for now), but I am missing some key bits of info. The main problems I'm having: - I know that I will need to supply a function/handler for 'showRequest' and 'showResponse' but I don't know what should go into these. Could you update your examples above with something simple? - I know you said that it is app dependent, but for purposes of filling out this tutorial, could you post more of your 'upload' view routine, specifically the return? - could you discuss more about how to map the 'upload' and 'get_upload_progress' in urls.py, and how that relates to the view containing the upload form? Do I need 3 entries in urls.py? (one for the form, one for 'upload', and one for 'get_upload_progress'? - any idea how this might be modified for handling multiple files in a Django-friendly manner?

Here is another one using emoticons: http://www.stanford.edu/~alecmgo/cs224n/twitterdata.2009.05.25.c.zip I had to manually classified the tweets on my side because they are in French and I didn't find a pre-classified corpus in French. @Elliott Thanks for the link to that pre-classified test corpus.

I am trimming the number of word features in the real application but I keep it simpler for the post. @ Hywel I fixed the call to get_word_features.

The same can apply to other languages. I am actually using that method to classify tweets written in French. I am not satisfied with the results yet because the sample I classified manually is too small. An issue with other languages than English is that it is difficult to find a large corpus of classified tweets. @Hywel You are correct. The same can apply to other languages.

I also stored the tweets in a Redis DB in 2 different lists: positive and negative. For the article, I am using hard coded list to simplify things. @Elliott I built a simple web interface to help me classifying the tweets.
