What is Document Parsing? A Comprehensive Guide to Understanding and Utilizing This Crucial Process

Many companies are overflowing with documents and find it challenging to sort through them all. Document parsing helps companies automate data extraction, enhance accuracy, and streamline operations. 

Document parsing uses clever technology to analyze different formats, like contracts, emails, or even PDFs, and then extracts the key details you need. Think of names, dates, numbers, or specific phrases. It's like having a map to navigate the document and find the treasure you seek, saving you time and effort.

In this comprehensive guide, we will explore the fundamental aspects of document parsing, its benefits, extended use cases, and the relevant programming languages and tools. We will also provide detailed step-by-step instructions for implementation.

What is document parsing?

Document parsing is a sophisticated process that involves extracting structured data from unstructured documents. Unstructured documents, such as invoices, contracts, and forms, often contain valuable information but need a standardized format. 

Document parsing is the key to unlocking this data by analyzing the document’s content, identifying relevant information, and structuring it into a usable format.

What are the steps involved in the mechanism of document parsing?

Once you identify the type of information you want to extract and define the data structure, you must gather all the documents you wish to extract in one place. And then the following steps need to be taken:

• Text Extraction: You may have documents in different formats, such as PDF, Word, HTML, etc. The first step is to convert all these types of files into machine-readable text files. This is usually done using Optical Character Recognition (OCR), but there are other text extraction methods, too.
• Tokenization: For the machine to scan the documents, the text is broken into ‘tokens,’ which are nothing but words or sub-words.
• Named Entity Recognition (NER): This is also sometimes called natural language processing (NLP), wherein entities, such as names, dates, amounts, and addresses within the document, are identified and classified, and a syntactic analysis is done on them to understand the grammatical structure of the text.
• Structuring: This removes irrelevant or redundant information and handles noise in video files, errors, or inconsistencies in the text. Once the clean-up is done, the identified information is organized into a structured format, such as tables or key-value pairs.

Benefits of document parsing

Though many don’t look at it this way, document parsing goes a long way in increasing the creativity and productivity of an organization. All departments and teams can benefit from document parsing as it helps streamline mindlessly repetitive tasks and quickly increases the utility value of collected data. Here are some of the benefits:

• Cost saving and improved efficiency: Automating the data extraction process significantly reduces time spent on manual data entry, especially when mundane tasks become time-consuming. For instance, automating invoice processing, which requires large volumes of data to be extracted quickly and accurately, can reduce operational costs as you won’t need underwriting teams anymore.
• Data digitization and accuracy: Individuals and businesses can benefit by using parsers for data entry automation and digitalization. This also reduces manual data entry errors, enhancing accuracy and overall data quality. This is paramount for operations teams dealing with sensitive information and regulatory requirements.
• Enhanced team productivity: Automating mundane repetitive tasks can free you and your team to spend more time on strategizing and other creative tasks, increasing productivity, job satisfaction, and performance. Remember, a winning team ultimately leads to better ROI.
• Scalability: Workflow automation is the key to scaling up operations because as your organization grows, so will the volume of documents to be processed. Parsing is a scalable solution that enables your organization to handle large datasets without hiring more people.

Use Cases of document parsing

Every industry struggling to accumulate documents, user information, and voluminous data sets can use parsing to optimize operations and increase efficiency. Some use cases of document parsing are:

• Invoice Processing: Using document parsing to capture valuable information from documents means error-free data extraction of multiple fields such as dates, amounts, and other line items. Automation can accelerate the billing cycle and improve the accuracy of financial transactions.
• Contract Analysis is of utmost importance for procurement and legal teams. Quickly extracting terms, conditions, and important clauses can improve work efficiency and enable quick reviews of contractual obligations and compliance.
• Form Processing: For companies and departments dealing with voluminous form submissions – like human resources, customer service, surveys, feedback centers, etc. - streamlining the extraction of data from various types of documents can be done pronto. 
• Legal Document Analysis: Parsing is especially important in legal documents where accurate compliance means risk mitigation. For law firms and company legal departments, document parsing reduces the risk of oversight.
• Underwriting Optimization: Take the insurance industry, where a massive pile of documents about policyholders daily. Coverage details, risk assessments, and other vital information can be accurately extracted, optimizing the underwriting teams' operations.
• Healthcare Data Extraction: In the healthcare sector, the accuracy of stored patient information and other critical data can be increased manifold with document parsing. Medical records, insurance claims, and other health-related information of the patients can be accurately classified with automated parsers.

Using programming languages for document parsing

Parsers are used in all high-level programming languages. The coding language becomes all-important because parsers must be correctly integrated into existing systems for smooth workflow automation. 

Especially if you plan to develop your parser (hint: it’s time-consuming and costly, so go for AI-enhanced software), the programming language you choose may be critical. Some of the languages used by most software out there are:

• Python is the most popular language for parsing solutions. It’s versatile and suitable for a wide range of applications, and its extensive libraries and frameworks make it the chosen one across industries.
• Java: If you deal with enormous amounts of data, Java is for you. Enterprises with diverse tech stacks prefer it because of its platform independence, which enables speedy parsing.
• JavaScript: Use it with frameworks like Node.js for web-based document parsing applications, and you’ll have an efficient automated system in place. For any parsing in the online space, JavaScript is the go-to programming language.

Using document parsing tools and software

The bottom line is that the software you choose should provide easy-to-use APIs that are compatible with multiple programming languages

• Docsumo: A powerful document parsing tool that automates data extraction from invoices, receipts, and other documents. Its advanced features, such as machine learning-based recognition, make it a go-to solution for various industries.
• NLTK (Natural Language Toolkit): This toolkit works with human language data. It is a Python library known for efficient tokenization and named entity recognition, especially when parsing documents with specific linguistic requirements.
• Amazon Textract: An AWS service that automatically extracts text, forms, and tables from scanned documents – famous for leveraging cloud infrastructure for document parsing at scale.

Again, compatibility is the key. Check the performance based on the language of the text and region-based specificities.

• Docsumo API: Allows developers to integrate document parsing capabilities directly into their applications, enhancing data extraction at scale. With RESTful API endpoints, it facilitates seamless integration into existing workflows.
• Google Cloud Natural Language API: This API has pre-trained models for entity recognition and other natural language processing tasks. It can be used to leverage cloud-based document parsing solutions.
• Microsoft Azure Form Recognizer: is an Azure service with text, table, and key-value pair extraction capacities. It is mainly beneficial for use within the MS ecosystem.
