The system processes various types of content, such as documents uploaded to your Knowledge Base or questionnaires you want to auto-answer. While the system is designed to handle a wide range of content, sometimes issues can occur during processing, leading to "content problems." These problems can manifest as documents failing to process or questions not being answered automatically.
Understanding how to identify and address these issues ensures your content is effectively utilized by the system.
## Identifying Content Problems
### Knowledge Base Document Processing Failures
When you upload documents to your Knowledge Base, they go through a processing phase to extract information and make it available for answering questions. Sometimes, this process can fail.
### Check Document Status
Navigate to your Knowledge Base section. You will see a list of all uploaded documents. Each document will display its **Processing Status**.
### Understand Statuses
Observe the status of your documents:
- **Pending**: The document is waiting to be processed.
- **Processing**: The system is actively working on the document.
- **Completed**: The document has been successfully processed, and its content is available for use.
- **Failed**: The system encountered an error and could not process the document.
If a document's status is **Failed**, its content will not be used by the system to generate answers. You will need to investigate the cause or re-upload the document.
### Questionnaire Auto-Answering Errors
When you use the auto-answer feature for a questionnaire, the system attempts to generate answers based on your Knowledge Base. Individual questions or the entire auto-answering process can encounter issues.
### Review Auto-Answered Questionnaires
After initiating an auto-answer process, carefully review the generated answers within the questionnaire.
### Look for Missing or Error Messages
If a question could not be answered, you might observe:
- A blank answer field where an answer was expected.
- An explicit error message indicating why the answer generation failed for that specific question.
### Automation Failure Notifications
The system can send email notifications if an automation related to content processing (e.g., a task that involves content processing) encounters failures.
### Check Your Email for Automation Failure Alerts
You might receive an email with a subject like "Automation Failures" if a task involving content processing has issues.
### Review the Email Details
The email will provide key information, including:
- The number of automations that failed.
- The specific task title associated with the failure.
- The organization where the failure occurred.
- A direct link to view the task for more details.
## Common Causes and Solutions
### Knowledge Base Document Failures
Document processing can fail due to several reasons:
- **Unsupported file formats**: Ensure your document is in a supported format (e.g., PDF, common image formats, XLSX, CSV, TXT).
- **Corrupted files**: The file might be damaged or unreadable.
- **Content issues**: The document might contain content that the system cannot parse or understand effectively (e.g., extremely complex layouts, scanned images without OCR).
- **System errors**: Less commonly, an internal system issue might temporarily prevent processing.
**What to do:**
### Re-upload the Document
Try uploading the document again. Sometimes, transient issues can cause a failure that resolves on a second attempt.
### Check File Integrity and Format
Verify that the file is not corrupted and is in a common, supported format. If it's a less common format, try converting it to PDF or plain text.
### Simplify Content (if applicable)
If the document has complex layouts, many images, or unusual fonts, try creating a simpler version (e.g., a plain text version or a PDF with selectable text).
### Contact Support
If problems persist after trying the above steps, gather details about the document and any error messages you observed, then contact support for assistance.
### Questionnaire Auto-Answering Failures
Questions might not be auto-answered due to:
- **Lack of relevant information**: Your Knowledge Base might not contain sufficient or relevant information to answer the specific question.
- **Ambiguous questions**: The question might be phrased in a way that the AI cannot confidently match to your Knowledge Base content.
- **System limitations**: The AI model might not be able to generate a coherent answer even with seemingly relevant content.
**What to do:**
### Review Your Knowledge Base
Ensure your Knowledge Base contains documents that thoroughly cover the topics related to the unanswered questions. Upload more relevant content if needed.
### Manually Answer the Question
If the system cannot auto-answer, you can always provide a manual answer directly within the questionnaire.
### Refine Questions (if possible)
If you have control over the questionnaire, try rephrasing ambiguous questions to be more direct and specific.
## Managing Problematic Content
### Deleting Knowledge Base Documents
If a document consistently fails to process or is no longer relevant, you can remove it from your Knowledge Base.
### Locate the Document
Go to your Knowledge Base section where your documents are listed.
### Delete the Document
Find the document you want to remove and use the delete option provided (e.g., a trash can icon or a "Delete" button). Confirm the deletion when prompted.
### Deleting Questionnaire Answers
If an auto-generated answer is incorrect, or you want to remove a manual answer, you can delete it from the questionnaire.
### Navigate to the Questionnaire
Open the specific questionnaire you are working on.
### Find the Answer
Locate the question whose answer you wish to delete.
### Remove the Answer
Use the delete option associated with that answer. This might be a button next to the answer field or within an edit menu.
The system also provides an advanced option to delete *all* manual answers for your organization. Use this feature with extreme caution as it is irreversible and will remove all manually provided answers across your entire organization's knowledge base. This is typically not needed for individual content problems.
