Frequently Asked Questions
What is unstructured data and why is it hard to process?
Unstructured data lacks a predefined schema: videos, images, PDFs, emails, audio recordings, and web pages. It is hard to process because each format has unique parsing requirements, content varies widely in quality and structure, and extracting meaningful information requires AI models rather than simple parsing rules.
How do I convert unstructured data into something AI can use?
The typical pipeline involves: parsing the raw content (extracting text, frames, audio), chunking into manageable segments, generating embeddings for each segment, and storing in a vector database for retrieval. Tools like Mixpeek handle this end-to-end, while others handle specific stages.
What is the difference between ETL and unstructured data processing?
Traditional ETL moves and transforms structured data between databases. Unstructured data processing converts raw content like images, videos, and documents into structured formats that downstream systems can use. The key difference is that unstructured processing requires content understanding, not just data transformation.
