# Use Knowledge Graph in ServiceNow Otto for HRSD

Create a personalized knowledge model as a Knowledge Graph schema.

The Virtual Agent uses the assigned Knowledge Graph schema to resolve the query and create an Employee Travel Visa Request. Here’s an example of how a Knowledge Graph schema assists a ServiceNow Otto in Virtual Agent user. Here’s an example of how a Knowledge Graph schema assists a ServiceNow Otto in Virtual Agent user.

Role required: none

## Procedure

1.  Navigate to **All** > **Employee Center**.

2.  Select **Open chat window**.

3.  Query the following: `Need to raise a travel visa request`.

4.  Select **Start** below **Employee Self Travel Visa Request**.

5.  The query is processed by Knowledge Graph and generates the following fields:

    -   Employee name
    -   Country of birth
    -   Country traveling to
    -   Travel start date
    -   Trip duration
    -   Business justification
6.  Fill in the required fields.

    Based on the Knowledge Graph schema selected, the Knowledge Graph searches all edges and nodes to provide available outputs such as **Employee name** and **Country of birth.**

7.  Edit the provided information before confirmation if needed.

    When confirmed, the request is processed with minimal effort from the user.


## Result

Knowledge Graph leverages the existing information that is available in the internal databases and auto-populates it to reduce efforts while making the entire experience seamless.
