Using Predictive Coding

When you set up a predictive coding project, Nebula automatically creates score fields. The new scoring fields display the project name, coding option, and choice can be viewed on the Document List using Customize Fields.

Documents are added into a predictive coding project through the Reviewer Document List.

To create a new predictive coding project

1. In the Nebula menu bar, click Review > Admin > Predictive Coding.
2. In the Predictive Coding heading, click the Select Project Action icon and select New Project.
3. In the New Project dialog box, enter the Project Name.
4. In the Security Level drop list, select the level of access to the object from the following:
• Public: Provides users with global permission to the object (Admin > User Groups > Default Permissions)
• Owner: Only available to the Owner of the object (and those with admin level permissions).
• Custom: Enables you manage the security on the group level (if you can see the groups) or the firm level (if you cannot see the groups).
5. Enter the Training Field Name.
6. In the New Project dialog box, click Create.
7. View the new project on the Predictive Coding page.



8. In the Index Fields section, view the default metadata from the documents the predictive coding service will take into account.
9. To edit the Index Fields, in the Index Fields heading, click Edit, then use the Edit Index Fields dialog box to choose the Selected index fields you want included and click Save.

Note: Index Fields cannot be edited after a training session has been run.

10. In the Classifiers section, click the Add icon .
11. In the Classifiers dialog box, select the language tags you want included in the predictive coding profile and click Select.

Note: Entries and edits on the Predictive Coding page are automatically saved.

To add documents to a coding profile

1. In Review, choose the Saved Search or document set from Review Explore menu (Review > Explore) with emails and attachments you want to include in the predictive coding profile. (This is the document collection predictive coding will learn from and provide a score or ranking to.)
2. On the Document List, click the Action icon and select Add to Predictive Coding.
3. On the Add Document Set dialog box, in the Add to Predictive Coding drop list, select the predictive coding project you created.
4. Click Add.
5. On the Predictive Coding page (Review > Admin > Predictive Coding), choose the predictive coding set from the menu bar drop list.



6. View the Indexing Status in beneath the Index Fields section.



7. View the document set selected in step 1 in the Index Documents section. When indexing completes, Train & Classify is available to run a training session.

To add classifiers

1. On the Predictive Coding page, in the Classifiers section, click the Add icon .
2. In the Classifiers dialog box, select the coding fields you want included in the predictive coding profile and click Select.

To delete classifiers

1. On the Predictive Coding page, in the Classifiers section, locate the classifier you want to delete and click its Delete icon .
2. On the Delete Confirmation dialog box, click Delete.

To edit index fields

Note: Index fields can only be edited if there are no training sessions for the current project.

1. On the Predictive Coding page, in the Index Fields header, click Edit.
2. On the Edit Index Fields dialog box, select the from the Available list the index fields you want included.
3. Click Save.

To run a training session

1. Before running a training session, create a seed set of documents (a collection of reviewed documents in the document set in which the training fields have been selected when coding the documents).
2. On your Review matter, click Review > Admin > Predictive Coding.
3. In the Predictive Coding menu, choose the project you want to work with using the project drop list.



4. Click Train & Classify.



Note: Should a training session fail, click Failed in the Last Training Session to view the details of the problem on the Tasks (Review) page.

To rebuild an index

Note: If new documents have not been added to an existing predictive coding project, the project's index must be built prior to the next training session.

1. On your Review matter, click Manage > Review > Predictive Coding.
2. In the Predictive Coding menu, choose the project you want to work with using the project drop list.
3. In the Indexed Documents header, click the Action icon and select Rebuild Index.

To view project's predictive coding training history

1. In the Nebula menu bar, click Review > Admin > Predictive Coding.
2. In the Predictive Coding menu, choose the project you want to work with using the project drop list.
3. Click its Action icon and select Training Histroy.
4. On the Training History dialog box, view the list of all training sessions that have been conducted for the project.



5. Click a training session's Status to view its task details on the Tasks (Review) page.
6. If a training session resulted in a Failed status with a single document error, click the Download Report icon in the session's Exceptions column to download an Exceptions Report.

To view predictive coding scores

1. In Review, choose the Saved Search (Review > Searches) or document set from Review Explore menu (Review > Explore) with predictive coding scores you want to view.
2. On the Document List, click the Action icon and select Customize Fields.
3. On the Doc List Views dialog box, click the Action icon to the right of Name and choose Add.
4. Enter a Name of the predictive coding listing view.
5. Select the Scope for the predictive coding listing view.

Note: The scope must be at the matter or user level.

6. In the left table, select the fields to include in your view, making sure to include the predictive coding scoring fields (those with a format of [profile name]/[coding option]/[choice].



7. Click Save.
8. Click Set Profile.
9. View the profile scores on the Document List.

Note: To avoid biased coding, avoid allowing reviewers to see the predictive coding scores on their listing view profiles (document list views).

To set the object level security for predictive coding

1. In the Predictive Coding menu, choose the project you want to work with using the project drop list.
2. Click its Action icon and select Object Security.
3. Complete the Object Security dialog box.
