What this category's data looks like
Complaint ticket data is primarily sourced from the ticket module of enterprise customer service CRM systems, obtained via API synchronization or manual export. Updates trigger automatically when ticket workflow nodes change, including creation, assignment, processing, and completed statuses. Individual ticket documents contain structured fields and free-form text content. Structured fields include ticket ID, user account, complaint category, and handler ID, with units of string, string, enumerated value, and string respectively. Free-form text consists of user complaint details and customer service communication records, stored as plain text or rich text.
What constraints these characteristics impose on the document parsing and chunking workflow
The mixed structure of structured and free-form text in tickets requires the parsing process to first distinguish field types, to avoid chunking enumerated fields together with user complaint details. The high-frequency updates tied to ticket workflow nodes require parsing tasks to support incremental triggering by ticket ID, to avoid repeated parsing of full ticket datasets. Significant variance exists in free-form text length, ranging from dozens of characters for short complaints to thousands of characters for multi-round communication records. This requires chunking logic to adapt to length fluctuations. Some tickets include attached communication records, so support is needed for parsing text content within attachments and associating it with the main ticket chunks.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Free-form text for complaint tickets includes multi-round communications. This length preserves complete semantics of individual conversation turns while avoiding overly long chunks that harm retrieval performance. |
incremental_parsing_switch | Enabled | Tickets are updated via workflow nodes. Incremental parsing reduces redundant computation overhead. |
field_recognition_threshold | 0.75 | Confidence threshold for distinguishing structured fields from free-form text, to avoid misclassifying communication content as ticket IDs. |
attachment_parsing_switch | Enabled | Some tickets include transcribed communication screenshots or recorded text. This setting extracts content from attachments. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing takes longer when a single ticket includes multi-round communication records. This duration covers parsing requirements for most tickets. |
maxChunkOverlap | 100–150 characters | Preserves semantic connections between adjacent chunks, avoiding context breaks during retrieval. |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific scenarios require targeted analysis, and it is recommended to test against your own samples before finalizing settings.
Three common errors
- Phenomenon: Parsed boolean ticket status fields become null values after processing by conditional judgment components. Cause: The parsing process does not explicitly convert boolean fields to the native boolean format compatible with components, leading to components failing to recognize the original data type.
- Phenomenon: The error "Cannot redefine property: toString at Object.defineProperty" occurs in production environments. Cause: Custom parsing scripts incorrectly rewrite prototype methods of built-in objects, triggering runtime property conflicts.
- Phenomenon: The number of chunks generated after parsing a single ticket exceeds the system's processing limit, causing abnormalities during the indexing phase. Cause: Segment parameters are not adjusted based on the length of free-form text in the ticket, resulting in chunk counts far exceeding the system's per-document chunk threshold.
How to verify correct configuration
- Upload a single standard ticket sample, view the parsed chunk list, and verify that structured fields are correctly identified and separated.
- Trigger an incremental update task, verify that only updated ticket nodes are re-parsed, and that unchanged tickets are not re-parsed repeatedly.
- Review parsing logs to confirm that communication text within attachments is correctly extracted and associated with corresponding ticket chunks.
- Adjust segment parameters, re-parse long-text tickets, and verify that chunk counts match expected thresholds.
