It involves teaching machines to understand, interpret, and generate human language in a way that is both meaningful and useful. NLP combines computational linguistics with statistical, machine learning, and deep learning models to process and analyze large amounts of natural language data. + +## Workflow Diagram + +```mermaid + +graph TD; + A[Start] --> B[Check NLTK Resources Availability]; + B --> C[Load or Download SentenceTransformer Model]; + C --> D[Read Input Text File]; + D --> E[Extract Keywords from Text]; + E --> F[Generate Text Summary]; + F --> G[Display Results]; + G --> H[End]; +``` + +## Steps and Processes + +### 1. Ensure NLTK Resources are Available +- The script ensures that necessary NLTK resources are downloaded and available for use. + +### 2. Load or Download SentenceTransformer Model +- The script loads the SentenceTransformer model from a local directory or downloads it if not available. + +### 3. Read Input Text File +- The script reads the input text file named `input.txt` from the current directory. + +### 4. Extract Keywords from Text +- The script extracts the top N keywords from the given text using word frequency and importance scores. + +### 5. Generate Text Summary +- The script summarizes the given text by selecting the top N most important sentences based on cosine similarity. + +### 6. Print Results +- The script prints the extracted keywords and the generated summary. + +## Functions + +- **load_or_download_model()**: Loads the SentenceTransformer model from a local directory or downloads it if not available. +- **download_nltk_resources()**: Ensures that necessary NLTK resources are downloaded and available. +- **extract_keywords(text, model, top_n=10)**: Extracts the top N keywords from the given text using word frequency and importance scores. +- **summarize_text(text, model, num_sentences=3)**: Summarizes the given text by selecting the top N most important sentences based on cosine similarity. +- **main()**: Main function that ensures NLTK resources are available, loads the model, reads the input text file, extracts keywords, generates a summary, and prints the results. + +## Usage + +- Ensure that the input text file `input.txt` is present in the current directory. +- Run the script to extract keywords and generate a summary of the text in `input.txt`. + +### Online Resources +- **NLTK Documentation**: [NLTK Documentation](https://www.nltk.org/documentation.html) provides comprehensive information on how to use the NLTK library for various NLP tasks. +- **SentenceTransformers Documentation**: [SentenceTransformers Documentation](https://www.sbert.net/docs/) offers detailed guides and examples on how to use the SentenceTransformers library for sentence embeddings and other NLP applications. +- **Kaggle**: [Kaggle](https://www.kaggle.com/) is a platform for data science competitions and datasets, where you can find numerous NLP datasets and projects. +- **Towards Data Science**: [Towards Data Science](https://towardsdatascience.com/) is a Medium publication with articles and tutorials on NLP and other data science topics. +- **Hugging Face**: [Hugging Face](https://huggingface.co/) provides a wide range of NLP models and datasets, along with an active community and resources for learning and collaboration. + +### Libraries +- **spaCy**: [spaCy](https://spacy.io/) is an open-source library for advanced NLP in Python, designed for production use. +- **Gensim**: [Gensim](https://radimrehurek.com/gensim/) is a library for topic modeling and document similarity analysis. +- **Transformers**: [Transformers](https://huggingface.co/transformers/) by Hugging Face is a library for state-of-the-art NLP models, including BERT, GPT-3, and more. +- **TextBlob**: [TextBlob](https://textblob.readthedocs.io/en/dev/) is a simple library for processing textual data, providing a consistent API for diving into common NLP tasks. +- **CoreNLP**: [CoreNLP](https://stanfordnlp.github.io/CoreNLP/) by Stanford NLP Group is a suite of NLP tools that provide various linguistic analysis tools. +- **Flair**: [Flair](https://github.com/flairNLP/flair) is a simple framework for state-of-the-art NLP, developed by Zalando Research. + +These resources and libraries can help you further enhance your NLP projects and stay updated with the latest advancements in the field. \ No newline at end of file
