How is unstructured data processed?
Processing unstructured data means extracting structure from it. Let’s look at the example of sentiment analysis, which is also known as opinion mining. Biometrics works by processing fingerprints and facial images to extract structured attributes. For example, ink smears turn into lines and polygons.

What are examples and characteristics of unstructured data?
Examples of unstructured data include text, video files, audio files, mobile activity, social media posts, satellite imagery, surveillance imagery – the list goes on and on. Unstructured data is difficult to deconstruct because it has no predefined data model, meaning it cannot be organized in relational databases.
What are the sources of unstructured data?

Which is an example of semi structured data?
Both documents and databases can be semi-structured. This type of data only represents about 5-10% of the data pie, but has critical business usage cases when used in combination with structured and unstructured data. Email is a very common example of a semi-structured data type.
