Code for my masters thesis, which contains the work from the following publications:

• Masrani, V., Murray, G., Field, T. S., & Carenini, G. (2017). Domain adaptation for detecting mild cognitive impairment. In Canadian Conference on Artificial Intelligence (pp. 248–259). Springer, Cham.
• Masrani, V., Murray, G., Field, T., & Carenini, G. (2017). Detecting dementia through retrospective analysis of routine blog posts by bloggers with dementia. In BioNLP 2017 (pp. 232–237).
• Field, T. S., Masrani, V., Murray, G., & Carenini, G. (2017). Improving Diagnostic Accuracy Of Alzheimer S Disease From Speech Analysis Using Markers Of Hemispatial Neglect. Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, 13(7), P157–P158.

. To run:

• Request access to the DementiaBank dataset from either Davida Fromm: [email protected] or Brian MacWhinney: [email protected]
• Once you have permission, email me at [email protected] to get a copy of the preprocessed dataset.
  • Place data alongside run.py.
  • Place lib within dementia_classifier/
• Install python requirements (may want to use a virtualenv)
• Note: May need to install the 'stopwords' and 'punkt' package for the NLTK python package.
• Make sure sql is installed on your system and create a database with the appropriate permissions to store the processed data and results. Modify dementia_classifier/db.py with the appropriate user, password, and database name.
• Start the stanford parser with:

  java -Xmx4g -cp "dementia_classifier/lib/stanford/stanford-corenlp-full-2015-12-09/*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 20000

• run with:

  python run.py

Error: "RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends.
