from topicgpt import config

# For NameFilter
config.azure_key = ""

# For GPT3.5 or GPT4 or Ada-002

Option 1: Easy to use

Step 1: Set parameters for the approach

params = {
    'preprocessing': {'words_range': (2, 500)},
    'name_filter': {},
    'embedding': {'model': 'bge', 'batch_size': 500, 'device': 'mps'},
    'clustering':{
        'model': 'hdbscan',
        'hdbscan': {'reduced_dim': 5, 'n_neighbors': 10, 'min_cluster_percent': 0.01, 'sampler': 'similarity'},
        'kmeans': {'reduced_dim': 5, 'n_neighbors': 10, 'n_clusters_list': [50, 15, 5], 'sampler': 'similarity'},
        'topic': {'model_name': "gpt-35-turbo-16k", 'temperature': 0.5, 'batch_size': 5, 'topk': 10},
    },
    'keywords': {'ngram_range': (1, 2), 'topk': 10},
    'save_file': {'data_file': '../save/data.csv', 'topic_file': '../save/topic.csv', 'plot_file': '../save/tree.txt'},
}

Step 2: Using the pipeline method

from topicgpt.pipeline import topic_modeling

topic_modeling("Your dataset name", "The text column name", params=params)

Option 2: Flexible to use

Step 1: Load your dataset (Only provide dataset name and column name)

Load your data, must be 'pandas.DataFrame' format.

import uuid
import pandas as pd

data_df = pd.read_csv("Your dataset name.csv")
# data transform 
data_df = data_df.rename(columns={'The text column name': 'input'})
data_df = data_df.dropna(subset=["input"])
data_df['input'] = data_df['input'].astype(str)
data_df['uuid'] = [str(uuid.uuid4()) for _ in range(len(data_df))]

Step 2: Set parameters for the approach

params = {
    'preprocessing': {'words_range': (2, 500)},
    'name_filter': {},
    'embedding': {'model': 'bge', 'batch_size': 500, 'device': 'mps'},
    'clustering':{
        'model': 'hdbscan',
        'hdbscan': {'reduced_dim': 5, 'n_neighbors': 10, 'min_cluster_percent': 0.01, 'sampler': 'similarity'},
        'kmeans': {'reduced_dim': 5, 'n_neighbors': 10, 'n_clusters_list': [50, 15, 5], 'sampler': 'similarity'},
        'topic': {'model_name': "gpt-35-turbo-16k", 'temperature': 0.5, 'batch_size': 5, 'topk': 10},
    },
    'keywords': {'ngram_range': (1, 2), 'topk': 10},
    'save_file': {'data_file': '../save/data.csv', 'topic_file': '../save/topic.csv', 'plot_file': '../save/tree.txt'},
}

Step 3: Preprocessing the data

from topicgpt.preprocessing import MinMaxLengthFilter, NameFilter
filter = MinMaxLengthFilter(words_range=params['preprocessing']['words_range'])
data_df = filter.transform(data_df)
# replace names in the text with 
filter = NameFilter()
data_df = filter.transform(data_df)

Step 4: Embedding the text

from topicgpt.walmart_llm import AdaEmbedModel, BGEEmbedModel
if params['embedding']['model'] == 'ada':
    llm = AdaEmbedModel(batch_size=params['embedding']['batch_size'])
elif params['embedding']['model'] == 'bge':
    llm = BGEEmbedModel(batch_size=params['embedding']['batch_size'], device=params['embedding']['device'])
else:
    raise ValueError(f"Don't support {params['embedding']} model")
embeddings = llm.embed_documents(data_df['input'].tolist())
data_df['embeddings'] = embeddings
data_df = data_df.dropna(subset=["embeddings"])

Step 5: Clustering

from topicgpt.clustering import HDBSCANClustering
if params['clustering']['model'] == 'hdbscan':
    model = HDBSCANClustering(reduced_dim=params['clustering']['hdbscan']['reduced_dim'], 
                                n_neighbors=params['clustering']['hdbscan']['n_neighbors'], 
                                min_cluster_percent=params['clustering']['hdbscan']['min_cluster_percent'],
                                sampler_mode=params['clustering']['hdbscan']['sampler'])
    clusters_list = model.transform(data_df)
    
    # generate topic and description
    from topicgpt.generation import TopicGenerator
    generator = TopicGenerator(model_name=params['clustering']['topic']['model_name'], 
                                temperature=params['clustering']['topic']['temperature'],
                                batch_size=params['clustering']['topic']['batch_size'], 
                                topk=params['clustering']['topic']['topk'])
    generator.transform(clusters_list)
    
elif params['clustering']['model'] == 'kmeans':
    from topicgpt.clustering import KmeansClustering
    model = KmeansClustering(n_neighbors=params['clustering']['kmeans']['n_neighbors'],
                                reduced_dim=params['clustering']['kmeans']['reduced_dim'],
                                n_clusters_list=params['clustering']['kmeans']['n_clusters_list'],
                                sampler_mode=params['clustering']['kmeans']['sampler'],
                                model_name=params['clustering']['topic']['model_name'], 
                                temperature=params['clustering']['topic']['temperature'],
                                batch_size=params['clustering']['topic']['batch_size'], 
                                topk=params['clustering']['topic']['topk'])
    clusters_list = model.transform(data_df)

Step 6: Generating Keywords

from topicgpt.generation import KeywordsExtractor
extractor = KeywordsExtractor(ngram_range=params['keywords']['ngram_range'], topk=params['keywords']['topk'])
extractor.transform(clusters_list)

Save 7: Save results

from topicgpt.persistence import transform_data_format, transform_topic_format, plot_topic_taxonomy_tree
saved_data = transform_data_format(clusters_list, dataset_name)
saved_data.to_csv(params['save_file']['data_file'], index=False)
topic_data = transform_topic_format(clusters_list, dataset_name)
topic_data.to_csv(params['save_file']['topic_file'], index=False)
plot_topic_taxonomy_tree(clusters_list, params['save_file']['plot_file'])
