regex for resume parsing

Question

I am using regex to extract specific sections from resumes, such as key skills, summary, and work experience. The approach involves:

First, I extract the text from the resume based on predefined sections (e.g., "Skills," "Summary," "Work Experience") which is done through api and gives result in json. This involves identifying the boundaries of each section. There is no problem till here.

I used regex only on for extracting sections and after extracting those sections i am just passing the name of the section to extract relevant details. For instance, if the section is "Skills," the regex will capture all the text under the "Skills" section until the next section begins.

However, this approach has limitations, especially with templates that vary significantly. The regex patterns used to identify and extract sections may not work consistently across different templates, which poses a challenge.

for section:

    def get_section(text, section_name):
    """
    Extract a specific section from the text based on the section name.
    Returns the text belonging to that section until the next section is found.
    """
    pattern = re.compile(
        rf'\b{section_name}\b\s*([\s\S]*?)(?=\b(EDUCATION|WORK EXPERIENCE|EXPERIENCE|SKILLS|SUMMARY)\b|$)',
        re.IGNORECASE
    )
    match = pattern.search(text)
    if match:
        return match.group(1).strip()
    return None

for skills:

def extract_skills(text):
    """Extract the skills section from the text."""
    return get_section(text, 'SKILLS') or "Skills not found"

for summary:

def extract_summary(text):
    """Extract the summary section from the text."""
    return get_section(text, 'SUMMARY') or "Summary not found"

The reason the text found for the summary section is cut off and the text for the skills section is that the summary section contains the word 'skills' which is also part of your regular expression. There is likely no way to always correctly parse all resumes (probably not even using other more advanced methods), so if you can only use regular expressions you need to decide how much time you want to invest in crafting a regular expression for decreasing marginal gains when trying to look into the edge cases.
