QRMine is a suite of qualitative research (QR) data mining tools in Python using Natural Language Processing (NLP) and Machine Learning (ML). QRMine is work in progress. [Read More..](https://nuchange.ca/2017/09/grounded-theory-qualitative-research-python.html)
## What it does
### NLP
* Lists common categories for open coding.
* Create a coding dictionary with categories, properties and dimensions.
* Topic modelling.
* Arrange docs according to topics.
* Compare two documents/interviews.
* Select documents/interviews by sentiment, category or title for further analysis.
* Sentiment analysis
### ML
* Accuracy of a neural network model trained using the data
* Confusion matrix from an support vector machine classifier
* K nearest neighbours of a given record
* K-Means clustering
* Principal Component Analysis (PCA)
* Association rules
## How to install
```text
pip install qrmine
python -m spacy download en_core_web_sm
```
### Mac users
* Mac users, please install *libomp* for XGBoost
```
brew install libomp
```
## How to Use
* input files are transcripts as txt files and a single csv file with numeric data. The output txt file can be specified.
* The coding dictionary, topics and topic assignments can be created from the entire corpus (all documents) using the respective command line options.
* Categories (concepts), summary and sentiment can be viewed for entire corpus or specific titles (documents) specified using the --titles switch. Sentence level sentiment output is possible with the --sentence flag.
* You can filter documents based on sentiment, titles or categories and do further analysis, using --filters or -f
* Many of the ML functions like neural network takes a second argument (-n) . In nnet -n signifies the number of epochs, number of clusters in kmeans, number of factors in pca, and number of neighbours in KNN. KNN also takes the --rec or -r argument to specify the record.
* Variables from csv can be selected using --titles (defaults to all). The first variable will be ignored (index) and the last will be the DV (dependant variable).
### Command-line options
```text

## Use it in your code
```python
from qrmine import Content
from qrmine import Network
from qrmine import Qrmine
from qrmine import ReadData
from qrmine import Sentiment
from qrmine import MLQRMine
```
* *More instructions and a jupyter notebook available [here.](https://nuchange.ca/2017/09/grounded-theory-qualitative-research-python.html)*
## Input file format
### NLP
Individual documents or interview transcripts in a single text file separated by Topic. Example below
```
Transcript of the first interview with John.
Any number of lines
First_Interview_John
Text of the second interview with Jane.
More text.
Second_Interview_Jane
....
```
Multiple files are suported, each having only one break tag at the bottom with the topic.
(The tag may be renamed in the future)
### ML
A single csv file with the following generic structure.
* Column 1 with identifier. If it is related to a text document as above, include the title.
* Last column has the dependent variable (DV). (NLP algorithms like the topic asignments may provide the DV)
* All independent variables (numerical) in between.
```
index, obesity, bmi, exercise, income, bp, fbs, has_diabetes
1, 0, 29, 1, 12, 120, 89, 1
2, 1, 32, 0, 9, 140, 92, 0
......
```
