corpusshow 0.1.3

Corpus-Show makes it easier and faster to visualize corpus through sentence embedding of corpus.

Corpus-Show

Corpus-Show helps to understand the corpus data distribution through various values generated from Sentence Transformer.

• Corpus-Show performs sentence embedding via Sentence Transformers, a Python framework for state-of-the-art sentence, text and image embeddings. [Paper] [Document] [Huggingface model]
• You can visualize the embedded sentences of each document generated from SentenceTransformers.
• Corpus-Show can also generate clusters with sentences embedded array through Scikit-Learn KMeans.
• The sentence transformer model is downloaded through the hugging face interface, and the default model is set to paraphrase-xlm-r-multilingual-v1, which supports multiple languages. However, you can easily input your custom model as a sentence transformer model through the hugging face interface. It is also easy to fine-tune via SBERT. For more models, please see this page.

Installation

$ pip install corpusshow

Tutorial

We provide tutorial notebooks for all the features we offer. We plan to provide additional docstrings or documentation from the official distribution version (major version 1 or higher).

Main Feature

It helps to create a simple but useful plot as shown below with a simple dataframe and column names as input, such as the following BBC sample dataset in ./data/bbc_news_dataset.csv.

	news	topic
0	Oil rebounds from weather effect (...)	business
1	Indonesia 'declines debt freeze' (...)	business
...	...	...
601	EU software patent law faces axe (...)	tech

1. CorpusClster

Contains 1 static method. You can create great pictures with:

from corpusshow import CorpusCluster

# Class arguments
csv_file_path = '../data/bbc_news_dataset.csv'
sentence_transformer_model_name = 'paraphrase-xlm-r-multilingual-v1'
target_col = 'news'
num_cluster = 4

# Get class object
cc = CorpusCluster(csv_file_path, sentence_transformer_model_name, target_col, num_cluster)

# 1. quick_corpus_show method: 
# Show figures without k-means clustering
cc.quick_corpus_show('topic', 'tsne2d', False, 'fig1.png')
cc.quick_corpus_show('topic', 'tsne3d', False, 'fig2.png')
cc.quick_corpus_show('topic', 'pca2d', False, 'fig3.png')
cc.quick_corpus_show('topic', 'pca3d', False, 'fig4.png')

# 2. quick_cluster_show method:
# Show figures with k-means clustering
df_returned = cc.quick_cluster_show('tsne2d', False, 'fig5.png')
df_returned = cc.quick_cluster_show('tsne3d', False, 'fig6.png')
df_returned = cc.quick_cluster_show('pcda2d', False, 'fig7.png')
df_returned = cc.quick_cluster_show('pcda2d', False, 'fig8.png')

• If you want to change the design of the plot, use matplotlib's RcParams method or the returned dataframe.
