There are industries that generate thousands of documents every day which have important information to be captured and can be used for analysis and other purposes. With the advent of Optical Character Recognition(OCR) software in the 1990s, it became quite easy to extract and store information from multiple files and sources that reduced the manual efforts of the industries. As technology has advanced over the years, the focus has shifted to Intelligent Data Extraction which involves not just capturing the data from the sources but carefully analyzing it and creating meaning out of it.

With the help of Intelligent Data Extraction, text can be extracted from digital assets like documents, emails, text files, scanned images, structured and unstructured data, and made available in usable formats with the help of defined rules and data extraction templates.

What is Intelligent Data Extraction?

Intelligent Data Extraction refers to the process of automatically extracting structured data from unstructured or semi-structured data sources such as text, images, or audio files, using machine learning algorithms, natural language processing (NLP), and other AI techniques. It involves analyzing large volumes of data to identify patterns and extract meaningful insights that can be used to inform business decisions.

Intelligent data extraction can be used in various industries, including finance, healthcare, and retail, to extract data from sources such as invoices, contracts, and customer feedback, among others. By automating the data extraction process, intelligent data extraction can help organizations save time, reduce errors, and improve accuracy in data analysis.

Traditional OCR Vs Intelligent Data Extraction

Intelligent data extraction differs from traditional data extraction methods in that it utilizes machine learning algorithms and NLP to extract structured data from unstructured or semi-structured sources. Other data extraction methods may rely on rule-based approaches or manual data entry, which can be time-consuming, error-prone, and less accurate.

For example, traditional data extraction methods might involve manual data entry of information from paper documents or manual entry of data into a database. This process can be tedious, time-consuming, and error-prone, especially when dealing with large volumes of data.

In contrast, intelligent data extraction uses advanced algorithms to automatically identify and extract data from unstructured or semi-structured sources, such as invoices or contracts. These algorithms can learn from past examples, improving accuracy over time, and can handle a wide variety of document formats and languages.

Overall, intelligent data extraction is faster, more accurate, and more efficient than traditional data extraction methods, making it a powerful tool for organizations looking to extract insights from large volumes of data.

How Does Intelligent Data Extraction Work?

Intelligent data extraction works by using advanced algorithms and machine learning techniques to identify and extract data from unstructured or semi-structured sources, such as invoices, contracts, or emails. Here are the steps involved in the intelligent data extraction process:

Data Ingestion:

The first step in the intelligent data extraction process is to ingest the unstructured or semi-structured data into the system. This data can come from a variety of sources, such as email attachments, scanned documents, or uploaded files.


The data is then pre-processed to prepare it for extraction. This may involve cleaning up the data, converting it into a standard format, or segmenting the data into different fields.

Training the Algorithm:

The next step is to train the algorithm to recognize specific data fields. This involves providing the system with examples of the data fields that need to be extracted and the locations where they can be found in the document.


Once the algorithm has been trained, it can be used to extract data from the unstructured or semi-structured sources. The algorithm analyzes the data and identifies patterns and features that match the trained examples. The extracted data is then outputted in a structured format, such as a CSV file or a database.


After extraction, the system checks the accuracy of the extracted data. If the data does not meet the required accuracy level, it is sent back for reprocessing.

Continuous Improvement:

Over time, the algorithm can learn from its mistakes and improve its accuracy. This is done by feeding back the extracted data into the system and using it to retrain the algorithm.

Benefits of Intelligent Data Extraction for Industries

Intelligent data extraction provides several benefits to organizations, including:

Increased Efficiency:

By automating the data extraction process, organizations can save time and increase efficiency. This is because intelligent data extraction can quickly and accurately extract data from unstructured or semi-structured sources, such as invoices or contracts, reducing the need for manual data entry.
