Unstructured data refers to information that doesn't have a predefined data model or organization. It typically includes:
Text documents (emails, reports, social media posts):
- Audio files
- Video files
- Images
- Web pages
Unlike structured data (e.g., spreadsheets or databases), unstructured data lacks a specific format or structure, making it challenging to process and analyze using traditional data analysis methods. It often contains rich, qualitative information but requires specialized techniques like natural language processing or machine learning to extract meaningful insights.
