Multi-source Employee Data

March 2, 2026

Adding a new field

profile_score is a model-derived quality score for our multi-source employee dataset, calculated from Professional network profiles. Using our profile dataset collection and integrated change-tracking data, we trained a model that performs score analysis across various profile features to produce a single numeric quality indicator per profile.

Data field	Description	Data type
profile_score	Model-derived employee profile quality score based on profile completeness and activity signals. Score range: 0 – 1	Double

---

How does it work?

The model evaluates profile features and assigns each an importance weight across three tiers:

1. Key drivers – carry the most weight; reflect core professional completeness.

• Connections, experience, and education – count and dates are the strongest signals of profile engagement, capturing depth of professional history and academic background.

• Activity count – posting, liking, and commenting activity serves as a key indicator of genuine platform engagement vs. automated or inactive accounts.

• Image authenticity – whether the profile photo is identified as real or not.

2. Profile completeness – add meaningful but smaller increments; capture profile richness and behavioral signals.

• Profile richness: headline length, summary presence, skills, websites, languages, and groups.

• Change signals: photo updates, activity changes, experience edits, and follower count changes.

• Naming patterns: casing, formatting, and dash usage in titles.

• Related data: similar profiles count, school/company URLs, job title and description presence.

3. Minor / negligible factors – minimal individual impact but contribute to the final score.

• Certifications, awards, volunteering, recommendations, publications, patents, courses, projects, and various other metadata fields.

Key takeaways

Use the score ranges below as a practical guide for evaluating profile reliability:

Score range	Interpretation
0.0 – 0.20	Low quality. Profiles to approach with caution or exclude.
0.21 – 0.40	Moderate quality. More likely to be real users than bots or inactive accounts.
0.40 – 1.0	Good to high quality. Growing signal of a genuine, active user.

Base Employee Data

March 4, 2026

Added a new field

The inferred_skills contains skills derived from structured and contextual profile information.

Data field	Description	Data type
inferred_skills	Lists employees' skills based on the descriptions from the profile	Array of strings

April 1, 2026

Scheduled removal: hidden_details

The hidden_details category will be removed from the Base Employee schema starting with the April 2026 dump.

Updates to the data aggregation pipeline now ensure that all necessary information is properly populated in the standard schema fields. As a result, the separate hidden_details identifier has become redundant.

Removed fields

Data field	Data type
hidden_details	Array of objects
hidden_details.hidden_collection	String

Employee Posts Data

created_at	The date and time when the employee post record was scraped and recorded in ISO 8601 format	String (date)
reshared_post.company_id	The company_id of the reshared post in case the post belongs to a company	Integer

[Reminder] Adding and fixing fields

Added fields

We are adding new company HQ location fields.

Job title classification updates

Changes

We are improving our job title classification system with refined department and management level categories.

Impacted fields

Dataset	Data fields
Clean Employee data	department management_level

C-Level migration: department → management_level

• The "C-Suite" department has been eliminated (previously 2.3M records).

• C-Level executives are now classified by their functional department (e.g., CFO → Finance & Accounting, CTO → Engineering and Technical), with "C-Level" assigned as their management level.

Reduced "Other" classifications

• The "Other" department has dropped from 8.9M to 2.1M records (76% reduction) as significantly more job titles are now accurately categorized into specific departments.

New category: "General Management"

• A new "General Management" department has been added to capture leadership roles that span multiple functions (4.5M records).
