PDF Liberation Hackathon 2014 Tackles Data Extraction Challenge
The PDF Liberation Hackathon 2014, held in New York City and Berlin, aimed to tackle a persistent challenge in data analysis: extracting structured data from Adobe PDFs, especially older ones. Participants focused on developing open-source tools to work with Adobe PDFs and their databases, as government agencies struggle to gain insights from data locked in this format.
The Adobe Portable Document Format (PDF), introduced in 1993, is widely used across organizations due to its consistency across devices and software, and its ability to be encrypted or digitally signed. However, data scientists often face hurdles extracting structured data from Adobe PDFs, particularly older ones that are scanned images.
At the hackathon, participants employed various techniques to prepare Adobe PDFs for computer-aided analysis. These included optical character recognition and specialized software for data tables. One dataset worked on was USAID's Development Experience Clearinghouse, containing around 170,000 documents. A USAID representative emphasized the potential of analyzing this data for deeper insights into foreign aid effectiveness.
The PDF Liberation Hackathon 2014 focused on Adobe tool development and did not produce any analysis. However, the future applications of these Adobe PDF data liberation tools could be widespread. With consistent and accessible data, government agencies can better track trends and gain insights, potentially improving the effectiveness of foreign aid and other areas relying heavily on Adobe PDF-stored data.
