Unstructured data is essentially everything else. This information is unnecessary to your analysis and will only skew the results so its important you learn how to clean your data. The text analytics process uses various algorithms such as understanding sentence structure to analyze the unstructured text and then extract information and transform that information into structured data.
Unstructured simply means that it is datasets typical large collections of files that arent stored in a structured database format. Nearly 80 of data in the enterprise is unstructured work descriptions résumés emails text documents research and legal reports voice recordings videos images and social media posts.

Structured data is often spoken of as quantitative data meaning its objective and pre-defined nature allows us to easily count measure and express data in numbers.
Other types of unstructured data include images audio and video files. Unstructured data is typically textual like open-ended survey responses and social media conversations but can also be non-textual like images video and audio. There is a lot of unstructured text data available for analysis.
Its so prolific because unstructured data could be anything. Unstructured data is information that has not been structured in a predefined manner. Media imaging audio sensor data text data and much more.
A file can be structured if the text is written in a consistent format even though normally we think of structured text as field-based. The examples of unstructured data vary from imagery and text files like PDF documents to video and audio files to name a few. Structured data has a predefined data model and is formatted to a set data structure before being placed in data storage eg schema-on-write whereas unstructured data is stored in its native format and not processed until it is used.
Unstructured data on the other hand is much less easy to quantify and does not readily fit into the structured format of spreadsheets and databases. It may be textual or non-textual and human- or machine-generated. Unstructured data has an internal structure but is not structured via predefined data models or schema.
It is qualitative data such as text images video and audio files and cannot be easily analysed using conventional data analysis tools. It may also be stored within a non-relational database like NoSQL. Previously a computer had to know the format in order to process the data properly.
Unstructured data typically text are data that does not have a predefined format eg e-mail word processing documents or presentations. You can get data from the below sources.
