What should I do?** + + There are several reasons behind this issue, but for most cases, you can try the following: + + - Set the `headless` parameter to `False` in the graph_config. Some javascript-heavy websites might require it. + + - Check your internet connection. Low speed or unstable connection can cause the HTML to not load properly. + + - Try using a proxy server to mask your IP address. Check out the :ref:`Proxy` section for more information on how to configure proxy settings. + + - Use a different LLM model. Some models might perform better on certain websites than others. + + - Set the `verbose` parameter to `True` in the graph_config to see more detailed logs. + + - Visualize the pipeline graphically using :ref:`Burr`. + + If the issue persists, please report it on the GitHub repository. + +6. **How does ScrapeGraphAI handle the context window limit of LLMs?** + + By splitting big websites/documents into chunks with overlaps and applying compression techniques to reduce the number of tokens. If multiple chunks are present, we will have multiple answers to the user prompt, and therefore, we merge them together in the last step of the scraping pipeline. + +7. **How can I contribute to ScrapeGraphAI?** + + You can contribute to ScrapeGraphAI by submitting bug reports, feature requests, or pull requests on the GitHub repository.

With the growth in movie piracy since the appearance of BitTorrent in 2003, films have become available through illegal piracy immediately after release in the US, while they are not available for legal viewing abroad until their foreign premieres in each country. We make use of this variation in international release lags to ask whether longer lags – which facilitate more local pre-release piracy – depress theatrical box office receipts, particularly after the widespread adoption of BitTorrent. We find that longer release windows are associated with decreased box office returns, even after controlling for film and country fixed effects. This relationship is much stronger in contexts where piracy is more prevalent: after BitTorrent’s adoption and in heavily-pirated genres. Our findings indicate that, as a lower bound, international box office returns in our sample were at least 7% lower than they would have been in the absence of pre-release piracy. By contrast, we do not see evidence of elevated sales displacement in US box office revenue following the adoption of BitTorrent, and we suggest that delayed legal availability of the content abroad may drive the losses to piracy." + # Add more sources here +] + +prompt = """ +You are an expert in reviewing academic manuscripts.
