Top 5 Skills Ontology Tools for HR & People Analytics Teams

Table of contents

Text Link

For businesses shifting towards a skills-first workforce, it’s essential to understand the need for robust skills ontologies. An Economic Graph by LinkedIn has found that skills-based recruitment helps expand the talent pool 6.1x globally by matching skills.

Despite this, organizations are still struggling with quality hiring. According to McKinsey, the acceptance rate is 56%, and the overall hiring success rate is 46% in Europe. This highlights the need for sharper skills intelligence. 

In this article, let’s explore the top skills ontology tools for HR and people analytics teams to standardize taxonomies and bring skill adjacencies to the surface. 

What are skills ontology tools?

A skills ontology is a system or a platform that helps businesses structure, map, and comprehend skills data by creating a relationship between varying competencies, roles, and skills. 

Take this as a skills dictionary and skills map that:

  • Standardizes Skills: Eradicates duplication (e.g., Python Programming vs. Python Developer)
  • Defines Relationships: Connects emerging or adjacent skills with core ones (e.g., Python → Machine Learning → Artificial Intelligence)
  • Supports HR & People Analytics: Allows skill gap analysis, reskilling initiatives, talent mobility, and workforce planning
  • Integrates with HR Tech: Several tools plug into performance systems, Applicant Tracking System (ATS), and Learning Management System (LMS) to keep the skills data up-to-date

How Skills Ontology Helps Organizations

As mentioned above, skills ontology helps businesses take inconsistent, scattered skills data and turn it into an actionable and structured framework. Here is how it impacts businesses:

  • Allows Skills-Based Mobility and Hiring: Assists recruiters in going beyond titles and matching people to roles based on transferable skills. 
  • Drives Learning & Development (L&D): Aligns training programs with skill gaps to ensure employees are upskilled in important areas. 
  • Removes Ambiguity: Standardizes skills and languages to provide a transparent view of the workforce capabilities.
  • Reveals Emerging & Adjacent Skills: Discovers trending or related skills to help organizations upskill proactively.
  • Supports Workforce Analytics & Planning: Offers insights on required vs. current skills to help HRs predict talent needs efficiently.
