data extraction in 2022

By using a data extraction process in your organization, you can speed up a lot of manual work, increase your productivity and automate workflows as well.

In this article, we will go through the data extraction process, the types of data extraction, and how they can benefit your business.

What is data extraction?

Data extraction refers to the process of retrieving information from unstructured data sources. With data extraction, the data can be refined so that it can be stored and further analyzed.

Data extraction is used throughout industries such as healthcare, financial services and the tech industry among others. With data extraction, businesses can automate their manual processes and thus, increase efficiency.

Data extraction and ETL

Data extraction is the first step in the ETL process. ETL stands for Extract, Transform and Load and includes the 3 processes. The main goal of ETL is to prepare the data to be loaded into a data warehouse, database or directly into a business application. ETL can be used in any type of industry such as healthcare, SaaS, and even retailers.

Difference between structured and unstructured data

Unstructured data include data which does not have a defined structure whereas structured data is data which has already been transformed into a well-defined data model.

Examples of unstructured data are e-commerce emails, confirmation orders, PDF invoices and flight booking emails. CSV file, XML file and JSON documents are structured data.

Types of data extraction methods

Data extraction can be done using several different methods. We have outlined some of them below:

Text extraction

Text extraction refers to scanning and retrieving specific words, phrases, keywords from different types of documents such as surveys, purchase orders, leads' emails. You just have to specify which data you want to extract and the text extraction tool will do the work automatically.

Optical character recognition (OCR)

OCR extracts and read data from images or scanned documents by identifying text inside the images, character by character, using Computer Vision. OCR is a complex process that requires a lot of computations to correctly identify text. Today, best OCR algorithms can even identify manually written text fairly reliably.

Automatic image annotation

Also known as automatic image tagging, this data labelling method is a process through which metadata are assigned to various entities in an image using Computer Vision, like for OCR. An example of image annotation would be to identify the name of an animal or a flower in a picture.

The data extraction process

Data extraction process

The extraction process depends on the type of data: unstructured and structured data.

1. Identify type of document

During this step we identify the kind of document we received: is it an email, an image or a PDF for example.

2. Choose the data extraction method

Once the type of document has been identified, it's time to choose which data extraction technique (as described above) you will use. For example, text-based documents such as emails will use the Text extraction methods, whereas scanned invoices (images) will use the OCR method.

In some cases, you can use several methods for the same document. For example, many PDFs both contain text encoded in the file on top of the image. You can then decide to directly access the text and figure out its position in the document, or apply OCR and identify the text with computer vision in the image.

3. Extract the data

The raw data is then extracted and structured according to a specific schema.

Benefits of data extraction for businesses

At some point, any business would need to extract data automatically if they want to streamline their processes. Some data extraction tools are even powered by machine learning and artificial intelligence to better understand document processes.

Here are the 3 top reasons why any organization should use include automatic data extraction in their workflows:

  • Less manual and human errors

It’s inevitable that errors will occur especially if your staff is going through hundreds of documents on a daily basis. Those errors can include missing, incomplete, or duplicate information.

Did you know that A&T had a lot of invoicing errors that cost the company millions of dollars?

Having an automated data extraction system in place will help diminish those mistakes and improve the accuracy and precision of your data.

45% of work activities can be automated using demonstrated technologies.

  • Cost and time savings

According to an article by Harvard Business Review published in 2019, professionals have to check their mailbox 15 times a day and waste time reading irrelevant emails.

SaneBox claimed that this was around 650 hours spent in unproductive work.

A data extraction tool will not only automate this process and save you time, but it also allows your employees to focus their creativity elsewhere.

Imagine having a million documents to go through on a monthly basis? Hiring additional staff for this type of work will cost you more than investing in an automated system.

Organizations are losing $140 billion each year in wasted time and resources, duplication of effort, and missed opportunities as a result of disconnected data.

  • Increase in business efficiency

Data come in different formats and layouts and as your business grows, it can become difficult to sort and collect data quickly, if done manually. Data extraction can help you to access those data faster and process them leading to better decision making as well.

An example is PDF data extraction which can be quite tedious to extract data from. A PDF data extractor software will automate this process and increase business efficiency.
