Parent Child Weightage Relation & Matching

In RChilli’s Search & Match Engine, the concept of Parent-Child Weightage is part of a customizable scoring mechanism used to evaluate how well a resume or job description (JD) matches another document (e.g., a job post or a candidate profile).

1. Parent-Child Hierarchy

• Parent attributes refer to broad matching categories such as:

  • Skills

  • Education

  • Experience

  • Location

  • Job Title

• Child attributes are sub-level components within these categories:

  • For Skills: Operational, Soft skills.

  • For Education: Degree, University, Graduation Year.

  • For Experience: Employer, Duration, Projects, Designation.

This hierarchical design ensures a layered comparison between documents, where both parent and child entities are assessed for relevance.

How Weightage Works in Matching

RChilli supports two types of scoring logic for matching:

A. Default (Baseline) Logic

• Assigns predefined weights to parent attributes.

• Used when no customization is needed.

• Works out-of-the-box.

B. Custom (Configurable) Logic

• You can manually assign weightage to each parent and child node.

• Example: You can allocate:

  • 50% to Skills (parent)

    • 30% to Operational Skills (child)

    • 20% to Soft Skills (child)

  • 20% to Education

  • 10% to Job Title

• These weights are applied during the match scoring process, influencing the final ranking of resumes or job descriptions.

This allows clients to fine-tune how much emphasis is placed on different data points during candidate/job matching operations.

Matching Use Cases Using Parent-Child Weightage

1. Resume to Job Matching

   • Skills, experience, and job titles are matched with varying emphasis, based on the custom weight setup.

2. Job to Job Matching

   • Compares similar roles across domains using taxonomies and weight distributions.

3. Resume to Resume Matching

   • Identifies similar candidates by evaluating layered data fields.

Matching is not just textual but semantic and contextual, thanks to the use of RChilli’s Taxonomy 3.0, which brings in synonyms, aliases, and domain-specific variations for enhanced relevance.

How to Customize Parent-Child Weightage

You can configure the matching logic either via:

• My Account Portal UI (for manual configuration).

• Search & Match API settings, where weights are passed as parameters in the JSON payload.

Refer to the Scoring Weightage Guide for more technical details.

Why This Matters

Customizing parent-child weightage allows you to:

• Tailor search results to your business priorities.

• Improve match quality by emphasizing the most critical attributes.

• Ensure consistent, bias-free candidate-job alignment.

For example:

A hiring team focused on skill sets can assign 60% weight to skills, while another prioritizing education can assign 40% to degrees/universities.
