Definite scoring only considers the unexpected events in v2 and does not compare . These events may or may not be present in the baseline. Definite scoring is simple and easy to interpret. Definite scoring works based on the following factors:
* For every unexpected cluster that is in v2 and not in v1, the overall score is reduced.
* For all unexpected clusters present in both v1 and v2, overall score is reduced only when the number of logs of that cluster are higher in v2.
* There is no normalization, hence definite scoring may not work if the log file is too large.
* Score Reduction is higher at higher sensitivity levels.
* By default, definite scoring will give a score of 0 (fail) whenever there is a critical error.
Score Reduction is higher for clusters with higher criticality.
To set the Definite Scoring algorithm follow the steps below:
1. Click System Setup in the navigation menu as shown below:
**2.** The following screen appears:
**3.** Add/Edit an application. Click[ Add Application](https://docs.opsmx.com/application-management/add-application) and[ Edit Application](https://docs.opsmx.com/application-management/edit-application) to know more.
a. After entering the application details you need to add a service.
b. Enter the Service Name in the text box and click Save. Refer to the image below:
****
4\. Next, you get the option to select the type of service you want to add. The options are:
* Deployment Verification
* Visibility
* Release Management
Select Deployment Verification. The following options appear:
Click the + icon to add a log template.
5\. The create Template screen appears as shown below:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.opsmx.com/opsmx-1/opsmx-context-engine/additional-resources/previous-releases/isd-3.10/data-and-intelligence-module-autopilot/continuous-verification/scoring-algorithms/definite-scoring.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
