What Is Resume Parsing?

Resume parsing is a technology that automates the extraction of information from resumes. It scans and categorizes details like work experience, skills, and education into structured formats, usually for storage in databases or applicant tracking systems.
This automation streamlines the recruitment process, allowing recruiters to quickly search, filter, and evaluate candidates based on specific criteria, saving time and improving efficiency.

Resume parsing techniques use various methods to extract and categorize information from resumes efficiently.
These methods may include keyword identification, syntactical analysis, pattern recognition, and machine learning algorithms. The goal is to automate the extraction process, making it easier for recruiters and hiring managers to review candidate qualifications and make informed decisions.

let's explore 4 techniques of resume parsing:

1. Keyword-Based Parsers

The most rudimentary of all resume parsing techniques, keyword-based parsers, function by identifying specific words, phrases, and patterns within the resume text.
For instance, they may look for a sequence of four numbers to denote a year, but this approach has its limitations. It often fails to contextualize the data, mistaking a year of birth for a year of employment, or interpreting a term like ‘marketing’ in multiple, sometimes incorrect ways.
Despite its simplicity, keyword-based parsing is prone to errors, with an accuracy rate of around 70%.

2. Grammar-Based Parsers

A step up from keyword-based parsers, grammar-based parsers utilize a set of grammatical rules to interpret the information on resumes.

These parsers are more adept at understanding the various contexts of a word and can combine phrases and words to discern the meaning of each sentence. Though they require significant manual input during the setup, a well-coded grammar-based parser can analyze a resume effectively, boasting an accuracy rate of around 90%.

3. Statistical-Based Parsers

One of the resume parsing techniques is Statistical-Based Parsers. They apply numerical models to text to determine the context in which a word or phrase is used. They can differentiate whether a term like ‘coordination’ is a skill or part of a job description.

For these parsers to achieve accuracy, they must process a large volume of resumes to understand the information that needs to be extracted. Statistical parsers offer a balance between the low accuracy of keyword parsers and the higher accuracy of grammatical parsers.

4. AI-Based Parsers

At the forefront of resume parsing techniques are AI-based parsers. Leveraging advancements in artificial intelligence and machine learning, these parsers continuously improve as they process more data.

AI-based parsers excel in understanding the nuances of language, often surpassing human capabilities. They can interpret complex information layers in resumes, recognize spatial cues, and provide highly accurate parsing.

Modern AI parsers can understand language nuances and context better than previous methods, marking a significant breakthrough in resume parsing technology.

Why You Only Need AI Parsing

AI parsing technologies have revolutionized resume parsing by offering human-level understanding and versatility.

For instance, one of the best resume parsers uses AI to surpass traditional keyword, grammar, and statistical methods.
The AI models are tested against benchmarks to ensure superior language comprehension, outperforming human understanding in some aspects.
This capability allows AI parsers to understand multiple layers of information in a resume, picking up on spatial cues and context that traditional methods might miss.

The Benefits of Resume Parsing

Resume parsing offers several advantages to organizations. It saves time by efficiently sorting through resumes, keeps accurate records of applicants, saves resources, and importantly, helps eliminate biases in the recruitment process. By focusing on keywords and qualifications, resume parsing ensures that all candidates reaching the recruiter meet the basic job requirements, thereby streamlining the hiring process.

How Does Resume Parsing Work?

Understanding the mechanics behind resume parsing is crucial. The process typically involves three steps:

Conversion:

The parser identifies keywords and converts unstructured data into a structured format.
Separation: It then segregates the information into relevant fields, such as work experience, skills, and education.

Structuring Data:

Finally, the parser organizes the data into an easy-to-review format, providing a comprehensive overview of each candidate's profile.

Who Should Use Resume Parsing?

Resume parsing is beneficial for various roles within an organization:

Recruiters benefit from quicker screening of applications.
Hiring managers can further narrow down candidate selections based on specific criteria.
HR departments, regardless of size, can ensure a consistent and efficient hiring process.

Tips for Effective Resume Parsing

To maximize the benefits of resume parsing, consider the following tips:

Evaluate different resume parsing software options, considering their parsing capabilities.
Don't rely solely on the software; periodically review its performance to ensure it meets your organization's needs.
Make job postings specific to improve the accuracy of parsed data.
Be cautious of keyword-heavy resumes that might not reflect the candidate's actual experience or qualifications.
