quicktopic 1.0.2

Quick Topic Mining Toolkit (QTMT)
The quick-topic toolkit allows us to quickly evaluate topic models in various methods.
Features

Topic Prevalence Trends Analysis
Topic Interaction Strength Analysis
Topic Transition Analysis
Topic Trends of Numbers of Document Containing Keywords
Topic Trends Correlation Analysis
Topic Similarity between Trends
Summarize Sentence Numbers By Keywords
Topic visualization

This version supports topic modeling from both English and Chinese text.

Basic Usage
Example: generate topic models for each category in the dataset files
from quick_topic.topic_modeling.lda import build_lda_models
# step 1: data file
meta_csv_file="datasets/list_country.csv"
raw_text_folder="datasets/raw_text"
# term files used for word segementation
list_term_file = [
"../datasets/keywords/countries.csv",
"../datasets/keywords/leaders_unique_names.csv",
"../datasets/keywords/carbon2.csv"
]
# removed words
stop_words_path = "../datasets/stopwords/hit_stopwords.txt"
# run shell
list_category = build_lda_models(
meta_csv_file=meta_csv_file,
raw_text_folder=raw_text_folder,
output_folder="results/topic_modeling",
list_term_file=list_term_file,
stopwords_path=stop_words_path,
prefix_filename="text_",
num_topics=6
)

GUI
After installing the quick-topic package, run qtmt in the Terminal to call the GUI application.
$ qtmt

Advanced Usage
Example 1: Topic Prevalence over Time
from quick_topic.topic_prevalence.main import *
# data file: a csv file; a folder with txt files named the same as the ID field in the csv file
meta_csv_file = "datasets/list_country.csv"
text_root = r"datasets/raw_text"
# word segmentation data files
list_keywords_path = [
"../datasets/keywords/countries.csv",

# run-all
run_topic_prevalence(
meta_csv_file=meta_csv_file,
raw_text_folder=text_root,
save_root_folder="results/topic_prevalence",
list_keywords_path=list_keywords_path,

"../datasets/keywords/countries.csv",
"../datasets/keywords/leaders_unique_names.csv",
"../datasets/keywords/carbon2.csv"
]
# remove files
stopwords_path = "../datasets/stopwords/hit_stopwords.txt"
# set predefined topic labels
label_names = ['经济主题', '能源主题', '公众主题', '政府主题']
# set keywords for each topic
topic_economics = ['投资', '融资', '经济', '租金', '政府', '就业', '岗位', '工作', '职业', '技能']
topic_energy = ['绿色', '排放', '氢能', '生物能', '天然气', '风能', '石油', '煤炭', '电力', '能源', '消耗', '矿产', '燃料', '电网', '发电']

'政府', '规模经济']
# a list of topics above
list_topics = [
topic_economics,
topic_energy,
topic_people,
topic_government
]
# if any keyword is the below one, then the keyword is removed from our consideration
filter_words = ['中国', '国家', '工作', '领域', '社会', '发展', '目标', '全国', '方式', '技术', '产业', '全球', '生活', '行动', '服务', '君联',
'研究', '利用', '意见']
# dictionaries
list_country=[
'巴西','印度','俄罗斯','南非'
]
# run shell
run_topic_interaction(
meta_csv_file=meta_csv_file,
raw_text_folder=text_root,
output_folder="results/topic_interaction/divided",
list_category=list_country, # a dictionary where each record contain a group of keywords
stopwords_path=stopwords_path,
weights_folder='results/topic_interaction/weights',
list_keywords_path=list_keywords_path,
label_names=label_names,
list_topics=list_topics,
filter_words=filter_words,
# set field names
tag_field="area",

Example 3: Divide datasets by year or year-month
By year:
from quick_topic.topic_transition.divide_by_year import *
divide_by_year(

from quick_topic.topic_transition.divide_by_year_month import *
divide_by_year_month(
meta_csv_file="../datasets/list_g20_news_all_clean.csv",
raw_text_folder=r"datasets\g20_news_processed",
output_folder="results/test1/divided_by_year_month",
