What is Taxonomy API?

What is the RChilli Taxonomy API?

The Taxonomy API from RChilli is part of the Standardization/Taxonomy 3.0 suite, designed to provide intelligent, structured classification of skills and job profiles for resumes and job descriptions. It plays a critical role in enhancing search, matching, and data enrichment capabilities across HR systems.

Purpose and Capabilities

The Taxonomy API delivers:

• Standardized data using a global taxonomy of over 3 million skills and 2.4 million job profiles.

• Alternate names, synonyms, abbreviations, and comparable job titles or skills.

• Ontology-based tagging, allowing better classification for Solr/Elasticsearch or internal search engines.

• Smart suggestions for skills and job roles, improving candidate-job alignment.

For example:

• If a resume lists “Java Developer,” the API can return related roles like “Software Engineer,” and skills like “Spring Boot,” “REST API,” etc., along with aliases and domain context.

Use Cases

1. Resume Parsing Enrichment
   After parsing a resume, use the Taxonomy API to enhance the parsed output with:

   • Related skill terms and roles.

   • Expanded synonyms and domain tags.

2. Search & Match Optimization
   Improve search engine results by:

   • Feeding expanded taxonomy-based keywords into Solr/Elasticsearch.

   • Mapping job-seeker or recruiter queries to relevant profiles.

3. Job Description Analysis
   Automatically tag job descriptions with standard job titles and required skills, aligned to industry taxonomy.

4. Government Database Compliance
   Ensures alignment with standardized taxonomies from government databases in regions like the USA, EU, Canada, and Australia.

Maintenance & Updates

• The taxonomy data is refreshed monthly to include:

  • New job roles and skills.

  • Updates based on global industry changes.

  • Multilingual expansions.

  • Alignment with international standards.

API Integration Notes

• You must explicitly call the Taxonomy API to get real-time results such as:

  • Alternate names.

  • Intelligent recommendations.

  • Standardized terms.

It is not automatically invoked by the Resume or JD Parser unless specified.
