Every industry has its own jargon, acronyms, and shorthand. The Terminology Hub lets you define semantic domains — collections of terms, definitions, and synonyms that teach RelayHub’s AI how your organization talks. When the AI understands that “ARR” means Annual Recurring Revenue in your context (not an expression of frustration), its responses become significantly more accurate.

​
What Are Semantic Domains

A semantic domain is a named collection of terms grouped by topic or department. For example:
  • Sales Terminology — ARR, MRR, churn rate, pipeline, closed-won, ACV
  • Manufacturing Terms — BOM, lead time, WIP, yield rate, changeover
  • Healthcare Abbreviations — EMR, PHI, HIPAA, ICD-10, prior auth
Each domain contains individual terms with their definitions, synonyms, and any abbreviations or alternate spellings your team uses.

​
Creating a Domain

1
Open Terminology Hub
2
Click Terminology Hub in the left sidebar. You will see a list of any existing domains and a button to create a new one.
3
Name and describe the domain
4
Give the domain a clear name (like “Sales Terminology” or “Engineering Acronyms”) and a brief description of what it covers. The description helps the AI understand when to apply these terms.
5
Add terms manually
6
Click Add Term to define individual entries. For each term, provide:
7
  • Term — The word or phrase (e.g., “ARR”)
  • Definition — What it means in your organization’s context (e.g., “Annual Recurring Revenue — the total value of recurring subscription contracts normalized to a one-year period”)
  • Synonyms — Alternate forms the AI should recognize (e.g., “annual recurring revenue”, “annual run rate”)
    • 8
    Save the domain
    9
    Once you have added your terms, save the domain. It becomes active immediately — the AI will reference these definitions in all future conversations.

    ​
    AI Auto-Generation

    You do not have to enter every term manually. The Terminology Hub includes an AI-powered generation feature that can build an entire domain from a brief description.
    1
    Click “Auto-Generate”
    2
    On the domain creation screen, click the Auto-Generate button.
    3
    Describe your domain
    4
    Enter a natural language description of the terminology area you want to cover. For example:
    5
    “Commercial real estate terminology including terms related to leasing, property valuation, tenant management, and investment metrics.”
    6
    Review and edit
    7
    The AI generates a list of terms with definitions and synonyms. Review the output, remove any terms that are not relevant, edit definitions to match your organization’s specific usage, and add any terms the AI missed.
    Auto-generation works best when you provide a specific description. “Finance terms” is too broad. “SaaS financial metrics used in board reporting” gives the AI enough context to generate highly relevant terms.

    ​
    How Terminology Improves AI Responses

    When a semantic domain is active, the AI incorporates those definitions in several ways:
    • Disambiguation — The AI knows that “pipeline” in your sales context means deal pipeline, not a data pipeline or oil pipeline
    • Acronym expansion — When you type “What’s our current ARR?”, the AI understands you are asking about revenue, not making a typo
    • Synonym recognition — Whether a document says “churn rate”, “attrition rate”, or “customer turnover”, the AI maps them to the same concept
    • Response language — The AI mirrors your organization’s preferred terminology in its answers rather than using generic alternatives
    Terminology domains apply across all conversations for users in your organization. You do not need to remind the AI of your terminology in each chat.

    ​
    Managing Existing Domains

    From the Terminology Hub list view, you can:
    • Edit a domain to add, remove, or modify terms
    • Disable a domain temporarily without deleting it
    • Delete a domain if it is no longer needed

    ​
    Best Practices

    Be specific with definitions

    Do not just define “ARR” as “Annual Recurring Revenue.” Add context: how your company calculates it, what it includes and excludes, and any nuances specific to your business.

    Include common misspellings

    If your team frequently types “gaurantee” instead of “guarantee” or uses inconsistent abbreviations, add those as synonyms so the AI can still match correctly.

    Group logically

    Create separate domains for different departments or topics rather than one massive domain. This keeps things organized and makes it easy to enable or disable sets of terms.

    Update regularly

    As your business introduces new products, metrics, or processes, add the associated terminology. Stale domains reduce AI accuracy over time.
