NLPower

NLPower is a FastAPI-based service designed to provide real-time text analysis. It leverages some Natural Language Processing (NLP) libraries to offer functionalities such as sentiment analysis, keyword extraction, and text summarization.

This API can be used as a standalone service or integrated into front-end applications, data analytics tools, or any system that requires automated text understanding.

• Sentiment Analysis: Determine if the sentiment of the input text is positive or negative.
• Keyword Extraction: Extract significant keywords from the provided text.
• Text Summarization: Generate a concise summary of the given text.

• FastAPI
• spacy
• nltk

Make sure you have Python 3.8+ installed on your machine. It is also recommended to use a virtual environment for Python projects.

1. Clone the repository

   git clone https://github.com/yourusername/nlpower.git
   cd nlpower

2. Install required Python packages

   pip3 install -r requirements.txt

3. Download necessary NLP models

   python3 -m spacy download en_core_web_sm
   python3 -m nltk.downloader popular

1. Start the FastAPI server

   uvicorn app.main:app --reload

The API should now be running on http://localhost:8000. You can access the documentation at http://localhost:8000/docs.

Here's an example of how to use the API via curl:

  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{"text": "FastAPI is a modern, fast (high-performance), web framework for building APIs."}'

Response

{
  "result": "FastAPI, modern, fast, web, framework, APIs"
}

• Text Summarization
