catd

A Chinese co-word analysis with topic discovery package.

Overview

The catd co-word analysis with topic discovery package is intend for Chinese corpus analysis.

Use case

For better experience, you can run this script (with your corpus which have list of documents separated by '\n'.)

Corpus('$ProjectRoot/data/original_data/tianya_posts_test_set_10.txt):

documents1
documents2
...

Program:

import catd
import os

corpus = []
with open(os.path.join('data', 'original_data', 'tianya_posts_test_set_10.txt'), encoding='utf-8') as f:
    for line in f:
        corpus.append(line)

stop_words_set = catd.util.collect_all_words_to_set_from_dir(os.path.join('data', 'stop_words'))

cut_corpus = catd.util.word_cut(corpus, stop_words_set)

word_net = catd.WordNet()
coded_corpus = word_net.generate_nodes_hash_and_edge(cut_corpus)
word_net.add_cut_corpus(coded_corpus)

Note

Now I am working on the efficient visualization for big graph (hundreds of millions of edges).

If you have any question or suggestion, feel free to contact the Author in English or Chinese. But for the benefit of all users, please make communicate in English when it is public.
