Data extraction is one of the most important steps in data analysis. If you need a way to get useful information out of your data, you might as well not even try to analyze it in the first place. But where should you start with so many different ways of extracting data available?
Data extraction steps and process
The data extraction process is a multi-step, multi-tool process. It begins with the planning of the data extraction project and then continues through the use of tools and techniques to gather and organize your data.
The following steps are involved in extracting your data:
- Planning – You need to carefully plan what you want to extract, how you will do it, and how long it will take.
- Designing – Once you have your plan in place, there are many ways that you can design a tool or script based on your needs. This step requires creativity since there are more perfect solutions for every situation; instead, think about what works best for each situation (e.g., if all of your text fields contain names, but some also contain phone numbers).
After designing comes coding or writing code for each tool created during this step as well as coming up with ideas for other scripts that may be needed later down the road when completing other tasks such as aggregating results from multiple sources into one format so they can be combined easily without any errors occurring while doing so!
How to extract data from scanned documents
You can use OCR software to extract data from scanned documents. If you have a lot of documents to process, it’s best to batch-process them by importing them into the OCR data extraction software as a whole folder or zip file.
Once you’ve imported your images into an OCR program, select an appropriate recognition language (e.g., English) and then run the software.
Sutherland experts say, “The powerful input to output data extraction is really cognitive and looks after the operational challenges.”
If boxes around an image indicate that they contain text, select those boxes so they appear in green boxes on your screen—this will indicate which part of each image contains information that you want to extract and save as text or CSV files. To save extracted data, click “Save” at the top right of your screen and enter a name for each table extracted from its original source document (i.e., filename).
Benefits and Considerations of data extraction
People who perform data extraction are often in charge of sifting through large amounts of data and extracting relevant information. This can be done manually by a person or programmed to happen automatically, and either way, it can involve several steps. However, with the help of an automated system, you can reduce your costs for manual labor and increase accuracy, speed, and consistency.
Data extraction is a time-consuming process. It is expensive. There is no guarantee that the extracted data will be accurate or that it’s even possible to extract all required information from a given source. This is especially true for handwritten documents and images, where humans have to interpret what they see and put it into searchable text.
Data extraction is an essential part of your business’s success. It allows you to automate processes and save time while providing valuable insights into your company’s performance. Data extraction can be tricky at first, but once you learn the ins and outs of this process, it will become second nature!
