            Hi guys , how about creating something useful with code? I am looking to start a project which will use publicly available PDF files, extract the text and summarize them using AI. It could potentially be helpful to everyone. If you are interested in being a part of this effort or have ideas on a better project I'm excited to hear you. I'm a software engineer, I'm mostly using Python.
            

            Hi! As promised I've got a small but useful Python code example for you. This code is going to summarize a PDF text using the transformers pipeline. Here's a basic Python script that reads a PDF, extracts the text, and then summarizes it using the transformers pipeline with the bart-large-cnn model. You'll need to install the following libraries: PyPDF2 and Transformers. You can install them using pip:

            1. pip install PyPDF2
               

            --- Content provided by​ FirstRanker.com ---

            2. pip install transformers
               
            
            **Here's the Python code:**
            python
            

            --- Content provided by​ FirstRanker.com ---

            import PyPDF2
            from transformers import pipeline def read_pdf(file_path): with open(file_path, 'rb') as file: reader = PyPDF2.PdfReader(file) text = '' for page_num in range(len(reader.pages)): page = reader.pages[page_num] text += page.extract_text() return text def summarize_text(text): summarizer = pipeline("summarization", model="facebook/bart-large-cnn") summary = summarizer(text, max_length=130, min_length=30, do_sample=False) return summary[0]['summary_text'] if __name__ == "__main__": pdf_path = "your_pdf_file.pdf" # Replace with your PDF file path text = read_pdf(pdf_path) summary = summarize_text(text) print("Original Text:") print(text) print("\nSummary:") print(summary) **How to Use:** 1. **Install Libraries:** Make sure you have PyPDF2 and Transformers installed. python pip install PyPDF2 transformers 2. **Replace Placeholder:** Replace `"your_pdf_file.pdf"` with the path to your PDF file. 3. **Run the Script:** Execute the Python script. shell python your_script_name.py The script will print the original extracted text and the summarized version. Note:
            * This code may not work perfectly for all PDF files, especially those with complex formatting or images containing text.
            * The transformers pipeline might require a significant amount of memory, especially for large documents. Adjust the max\_length and min\_length parameters as needed.
            * Feel free to modify and improve this code to suit your specific requirements. I hope this helps!
