The main function

def main():
 if __name__ == "__main__":

    if len(sys.argv) != 4:
        print(' *', 'usage: <words file> <k, for doc 20>, <threshold, eg 0.9>')
        sys.exit(-1)

    f = sys.argv[1]
    k = int(sys.argv[2])
    t = float(sys.argv[3])

    words = load_tags(f)

    print(' *', 'generating dataset doc...')
    data, labels = make_data_matrix(words, t)

    print(' *', 'clustering doc...')
    word_cluster(data, labels, k=k, show_histogram_plot=True)
