Case Study: Categorizing and Sorting Job Descriptions with Taylor Classification


How Taylor helps US-based job aggregators structure their most important asset - job postings data - with robust categorizations.


The most problematic data often comes from external sources: sources you don’t own, control, or manage. This is particularly problematic when it’s unstructured text (like job descriptions, which are challenging to clean and sort).

Today, many HR Tech companies and job aggregation platforms are using job postings in their products for:

  • Content Aggregation: Collecting and listing content (e.g., a job board that aggregates job postings from multiple sites).
  • Product Development: Building products and services on jobs (e.g., a recommendation system for recommending similar jobs to applicants).
  • Analytics & Research: Analyzing trends and market research (e.g., tracking and analyzing the distribution of jobs and user preferences).

The biggest challenge to the above is making jobs data clean and usable. The below is a brief summary of how Taylor improves your jobs data with classifiers.

O*NET Classification

There are many jobs in the US. We classify jobs by ONET classifications so you have the most structured and comprehensive taxonomy to sort your jobs data.


For example, the above railway structural engineer job posting is tagged as 17-2051.00 which represents:

  • 17 - Major occupational group: Architecture & Eng Occupations
  • 20 - Minor occupational group: Engineers
  • 51 - Broad occupation: Civil Engineers
  • .00 - Detailed occupation: No further specialization for this occupation

Relevance Scoring

Not all jobs fit neatly in a single bucket. We provide relevance scores so you can set what level of relevance is necessary for an ONET classification to be deemed accurate and returned in the API response.

Multiple Labels

You may also want multiple classifications. We allow you to get multiple classifications. For example, an Account Manager job posting may be a combination of Customer Success and Sales.

Preprocessing

When you hit our API, we remove HTML tags and incorrect concatenations (e.g. “About UsAcme Company is a solar panel provider”) that are typical in jobs data. We also apply relevance filters so you can pass in the whole JD with irrelevant content (e.g. COVID-19 office policies). Your job descriptions may also have encoding errors (e.g. apostrophe as &#x or ellipsis as &hellip).

We take care of the data issues so your classifications are reliable.

Mapping ONET to Internal Taxonomy

In addition, we map ONET to your internal taxonomy so you get jobs labeled with both ONET and your internal (hopefully simpler!) taxonomy. When a job gets labeled with ONET, the associated secondary mapped label is also returned (if there are multiple labels mapped to an ONET code, the most relevant one is returned).


Get Started

To get started, you can use our API to classify your jobs. Sign in, grab your API key, and start classifying your jobs. The free tier allows you to classify 1,000 jobs as a trial.
