# Job Title Normalization
> Turn messy, real-world job titles into a clean, structured, and actionable taxonomy — available directly through the Crustdata Person API.
Job Title Normalization (JTN) is currently in **beta**. Field names,
taxonomy values, and confidence scoring may evolve based on feedback. To
share input or request access, write to
[support@crustdata.co](mailto:support@crustdata.co).
**Use this when** you need to clean up raw, free-text job titles for
targeting, market sizing, segmentation, or downstream analytics — without
building your own ML pipeline.
JTN transforms each raw title into a rich, structured record using
Crustdata's own ML models and a proprietary, data-derived taxonomy. Every
title is mapped to a high-level **Department**, a specific **Category
(Sub-Department)**, and a standardized **Matched Title**, and is returned
inline as `basic_profile.normalized_title`.
### Where JTN is available
JTN ships as a field on every person record returned by the Person APIs —
no extra endpoint or `fields` flag is required.
| API | Field path | Notes |
| ------------------------------------------------------------ | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
| [Person Enrich](/person-docs/enrichment/introduction) | `basic_profile.normalized_title` | Included whenever `basic_profile` is in `fields`. |
| [Person Search (PersonDB)](/person-docs/search/introduction) | `basic_profile.normalized_title` | Returned on every match. Also usable as a filter and sort field — see the [Person Search reference](/person-docs/search/reference#basic-profile). |
## The problem: messy title data
Raw job titles are wildly inconsistent, which makes accurate targeting,
market sizing, and segmentation nearly impossible. Real-world data is full
of:
* **Generic titles** — ambiguous roles like "Manager," "Director," or
"Consultant" that lack any functional context.
* **Acronyms & typos** — shorthand such as "MTS" or "SDE," plus
misspellings that general-purpose models struggle to interpret.
* **Non-English titles** — roles written in many different languages.
Without normalization, sales and marketing teams burn time manually
cleaning data — which leads directly to poor campaign performance and
inaccurate reporting.
## The solution: structured taxonomy mapping
Every raw title is mapped to three fields:
| Taxonomy field | Description | Example input | Example output |
| ----------------------------- | ------------------------------- | ----------------------------- | ------------------------------------- |
| **Department** | High-level function of the role | `Analyst II, Commercial Bank` | `Finance & Accounting` |
| **Category / Sub-Department** | Specific functional grouping | `Analyst II, Commercial Bank` | `Credit & Debt Management` |
| **Matched Title** | Standardized, canonical title | `Analyst II, Commercial Bank` | `Credit Analyst - Commercial Banking` |
### Why JTN
Unlike systems built on rigid public standards (such as ESCO), our
taxonomy is data-derived and powered by our own ML models. The model
focuses on a role's *functional intent* rather than its seniority or
rank — so `Senior Data Engineer` is correctly grouped with
`Data Engineer`.
JTN returns clean, structured fields (Department, Category, Matched
Title) that map cleanly into your CRM, campaign segmentation, and BI
tools — making your targeting immediately more granular and
effective.
## Example: Person Enrich response
JTN is exposed inline on the person record at
`basic_profile.normalized_title`. No extra `fields` flag is required — if
`basic_profile` is requested, `normalized_title` is included. The same
field is also returned on every [Person Search](/person-docs/search/introduction)
match.
### Example request
```json theme={"theme":"vitesse-black"}
{
"professional_network_profile_urls": ["https://www.linkedin.com/in/sharroh"],
"fields": ["basic_profile", "experience"]
}
```
### Example response (truncated)
```json theme={"theme":"vitesse-black"}
[
{
"matched_on": "https://www.linkedin.com/in/sharroh",
"match_type": "professional_network_profile_url",
"matches": [
{
"confidence_score": 1.0,
"person_data": {
"basic_profile": {
"current_title": "Software Engineer",
"name": "Rohit S",
"normalized_title": {
"confident": true,
"department": "Engineering & Technology",
"sub_department": "Software Engineering",
"matched_title": "Software Engineer - 2",
"similarity": 0.9047
}
}
}
}
]
}
]
```
### `normalized_title` field reference
| Field | Type | Description |
| ---------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------- |
| `department` | string | High-level function of the role. One of the 20 departments in the taxonomy. |
| `sub_department` | string | Specific functional grouping (Category). One of the 226 sub-departments in the taxonomy. |
| `matched_title` | string | Standardized canonical title that the raw input was mapped to. |
| `similarity` | float | Cosine similarity (0–1) between the raw input title and the matched canonical title. Higher = closer match. |
| `confident` | boolean | `true` when JTN's internal heuristics consider the mapping high-confidence. Use this as a filter for stricter downstream use. |
For strict segmentation use cases, filter on `normalized_title.confident == true`.
For broader coverage (e.g. enrichment top-ups), use all results and
inspect `similarity`.
