3. Usage

This MATLAB code can be used to reproduce the results from the works [1,2] from above. Before running the code, you need to install the following dependencies:

• VLFeat: http://www.vlfeat.org (place the library in the "code/vlfeat" subfolder)
• PQ Kernel: http://pq-kernel.herokuapp.com (place files directly in the "code" subfolder)
• LibSVM: https://www.csie.ntu.edu.tw/~cjlin/libsvm/ (after installation, add the corresponding path so that the functions svmtrain and svmpredict become available from everywhere in MATLAB)
• GloVe: https://nlp.stanford.edu/projects/glove/ (can be installed and used independently)

After installing the above frameworks, proceed as following:

1. Extract the GloVe word vectors from each text document and save the results in the "code/data" subfolder. The output for each text document should be written in a different .txt file. The output file should contain comma separated values with one word vector per line.
2. Run the following script in MATLAB:

>> runAll
