Document Classification Beginner Guide

Document Classification Beginner Guide

Welcome to the Document Classification Beginner Guide! Building upon the existing OCR Beginner Guide, this guide aims to provide you with a comprehensive understanding of classification techniques in the field of Intelligent Document Processing (IDP).

What is Document Classification?

In an IDP process, classification typically follows document capture. Classification involves the categorization or grouping of documents based on their content, structure, or other characteristics. It helps organize and streamline the processing of documents by assigning them to specific categories or classes.

Document Capture as a Prerequisite for Document Classification

Document capture is an essential prerequisite for classification, specifically in the context of OCR (optical character recognition) and ICR (intelligent character recognition) techniques. To initiate the classification process, it is imperative to capture the documents accurately. This involves acquiring the physical or digital copies of the documents and converting them into a suitable format for subsequent processing. Once the documents have been captured, machine learning classification algorithms can be implemented to analyze and efficiently classify them.

Rule-Based vs. Rule-Free Document Classification

Rule-Based vs. Rule-Free Document Classification

There are two main approaches to document classification: rule-based and rule-free (also known as machine learning-based) classification. Rule-based classification relies on human-defined rules and criteria sets. In contrast, rule-free classification utilizes machine learning algorithms to automatically learn patterns and features from the data.

One advantage of rule-free classification is its flexibility in handling large and diverse datasets. Rule-free classifiers can easily adapt to new document types and accommodate an expanding number of classes, making them highly scalable. Moreover, rule-free classification can be much faster to implement compared to rule-based approaches, which may require months to develop and fine-tune the rules, while rule-free classifiers can be trained in a matter of days.

Applications of Document Classification

Document classification finds applications in various industries and domains. Some common use cases include:


Document classification in banking streamlines processes like loan approvals and financial analysis by automatically categorizing documents such as loan applications, account statements, and legal agreements.


In the insurance industry, document classification helps manage policies, claims, contracts, and customer information, leading to faster claims processing, accurate risk assessment, and improved customer service.
