12 Deterministic QA Verification Rules

Every segment is inspected by our rigorous multi-check validation pipeline, protecting brand reputation and formatting compliance.

Tag Integrity

Validates inline XML/HTML tags and system variables to ensure identical structure between source and target.

Numerical Consistency

Flags discrepancies in numbers, decimal points, monetary formats, and measurement units across segments.

Glossary Compliance

Enforces approved terminology from bilingual glossaries and flags unauthorized translation variants.

Forbidden Terms

Detects restricted vocabulary, competitor names, or non-compliant terminology based on client guidelines.

Language-Specific Spelling

Multi-language spellcheck engine verifying grammar, accents, and local dialect requirements.

Punctuation Parity

Ensures closing periods, quotation marks, colons, and hyphens match the source structure.

Length & Expansion Check

Monitors character and word growth to prevent target text from breaking UI and subtitle reading speed.

Untranslated Content

Alerts when target text is empty or identical to the source without being marked as Do-Not-Translate.

Whitespace & Formatting

Identifies accidental double spaces, leading/trailing spaces, and broken line breaks.

URL & Hyperlink Syntax

Validates website links, email formats, and parameter strings within localized text.

Source/Target Mismatch

Detects missing sentences or excessive text truncation between source and target segments.

Semantic AI Validation

Employs LLMs to detect tone deviations, subtle hallucinations, and contextual mistranslations.
