visualizing topics #3
Description
Dear GSukr,
I use your very good code to visualize time varying topics. I can see the changes in the top 10 words of each topic without any problems in figures. But this is not the case with the topics. Would you please kindly help me in this regard? The relevant code is as below:
import pandas
result = pandas.read_csv('../sample-data/sample1.csv', encoding='utf_8')
news_abstract = result['newsAbstract']
news_text_normal = result['textField_normal']
news_time = result['time_jalali']
import dtmvisual
time_seq = [100,150,150,100]
dtm_path = 'C:/Downloads/dtm-win64.exe'
from dtmvisual.gensim_corpus import docs_to_list, corpus_dtm
sentences = docs_to_list(news_abstract)
corpus = corpus_dtm(sentences)
from dtmvisual.DTMmodel import dtm_model
model = dtm_model(dtm_path, corpus, time_seq, num_topics=8,
id2word=corpus.dictionary, alpha=0.01)
number_of_timespans = 4
number_of_topics = 8
from dtmvisual import visualize_words
df = visualize_words.DF(number_of_timespans, number_of_topics, model)
d = visualize_words.partitioning(df)
visualize_words.visualize_words(df, d)
#--------Topics evolution------
from dtmvisual import VisualizeTopics
df = VisualizeTopics.topic_distribution(number_of_topics, model, time_seq)
VisualizeTopics.visualize_topics(df)
'''
#Moreover, you save and then download your DTM model using:
dtmvisual.save_model(model, output_path, output_name)
model = dtmvisual.load_saved_model(output_path, output_name)
#To print the words for a timeslice for a topic use:
'''
from dtmvisual import DTMmodel
DTMmodel.print_all_topics(model, topicid = 7, time = 4, num_words=10)
