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..

What it does


  • 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


  • 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

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).

Use it in your code

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.

Input file format


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

Text of the second interview with Jane.
More text.


Multiple files are suported, each having only one break tag at the bottom with the topic. (The tag may be renamed in the future)


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
