⏳ Installation

Simply install via pip:

pip install textprepro

or:

pip install "git+https://github.com/umapornp/textprepro"

🚀 Quickstart

• 🧹 Simply preprocess with the pipeline

  You can preprocess your textual data by using the function preprocess_text() with the default pipeline as follows:

  >>> import textprepro as pre
  
  # Proprocess text.
  >>> text = "ChatGPT is AI chatbot developed by OpenAI It is built on top of OpenAI GPT foundational large language models and has been fine-tuned an approach to transfer learning using both supervised and reinforcement learning techniques"
  
  >>> text = pre.preprocess_text(text)
  >>> text
  "chatgpt ai chatbot developed openai built top openai gpt foundational large language model finetuned approach transfer learning using supervised reinforcement learning technique"
  

• 📂 Work with document or dataFrame

  You can preprocess your document or dataframe as follows:

  • If you work with a list of strings, you can use the function preprocess_document() to preprocess each of them.

    import textprepro as pre
    
    >>> document = ["Hello123", "World!@&"]
    >>> document = pre.preprocess_document(document)
    >>> document
    ["hello", "world"]
    

  • If you work with a dataframe, you can use the function apply() with the function preprocess_text() to apply the function to each row.

    import textprepro as pre
    import pandas as pd
    
    >>> document = {"text": ["Hello123", "World!@&"]}
    >>> df = pd.DataFrame(document)
    >>> df["clean_text"] = df["text"].apply(pre.preprocess_text)
    >>> df
    

    text	clean_text
    Hello123	hello
    World!@&	world

• 🪐 Customize your own pipeline

  You can customize your own preprocessing pipeline as follows:

  >>> import textprepro as pre
  
  # Customize pipeline.
  >>> pipeline = [
          pre.lower,
          pre.remove_punctuations,
          pre.expand_contractions,
          pre.lemmatize
      ]
  
  >>> text = "ChatGPT is AI chatbot developed by OpenAI It is built on top of OpenAI GPT foundational large language models and has been fine-tuned an approach to transfer learning using both supervised and reinforcement learning techniques"
  
  >>> text = pre.preprocess_text(text=text, pipeline=pipeline)
  >>> text
  "chatgpt is ai chatbot developed by openai it is built on top of openai gpt foundational large language model and ha been finetuned an approach to transfer learning using both supervised and reinforcement learning technique"
