Challenges of Working with Messy Data
Dealing with unstructured data in formats like PDFs, Word documents, and HTML poses significant challenges for AI systems, as they cannot always effectively process or interpret such data. Creating efficient workflows often leads to the need for handcrafted pipelines to extract and clean data into usable formats. However, these processes are inherently limited as they cannot accommodate all possible variations in data representation. This limitation is being addressed with new approaches, such as AI systems designed to analyze documents similarly to human beings, potentially making traditional data-cleaning steps obsolete.
