Workflow Orchestration for Complaint Ticket Smart Customer

Data Characteristics in This Category

Complaint ticket data in the biomedical field typically originates from patient feedback, medical institution reports, and adverse drug reaction event records. Data update frequencies vary, ranging from daily batch processing to real-time entry. Ticket document structures usually include structured fields and unstructured text. Structured fields include ticket number, complaint type, e.g., drug quality, service attitude, patient ID, reporting time, and processing status. Unstructured text covers patient descriptions and medical staff notes. This content may involve medical terminology, colloquial expressions, detailed descriptions of symptoms, medication, and treatment processes, often accompanied by emotional language. Time units are often "days" or "hours," and dosage units may include "mg" or "ml."

Constraints Imposed by These Characteristics on "Workflow Orchestration"

Complaint ticket data characteristics impose specific requirements on workflow orchestration. First, diverse data sources and varying update frequencies mean the workflow must support multiple data access methods and trigger flexibly based on data source update cycles. For example, real-time reported tickets require immediate workflow triggering for initial classification and response; batch-imported historical data can trigger periodically. Second, the mix of structured and unstructured data in tickets requires the workflow to effectively extract and understand information. Medical terminology and emotional expressions in unstructured text demand stronger natural language processing capabilities to accurately identify key information. Finally, the sensitivity and urgency of complaints dictate that workflows must have clear fallback and manual intervention mechanisms in case of processing failure, ensuring no omissions. For instance, complaints containing specific keywords should be escalated immediately.

Configuration Settings

Configuration Item	Recommended Value	Rationale for Recommendation
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Processing complex medical report attachments can be time-consuming for text parsing; this prevents timeout interruptions.
`maxContext`	`3000 characters`	Complaint descriptions can be long; sufficient context is needed to understand patient intent and details.
`Chunk size` (Segment Length)	`500 characters`	Balances semantic completeness with retrieval efficiency, avoiding information loss in long paragraphs or overly short segmentation.
`Recall count` (Recall Count)	`Top 8 entries` (top 8)	In complaint scenarios, increasing the recall count for similar historical cases and knowledge points improves coverage.
`Similarity threshold` (Similarity Threshold)	`0.75`	Ensures recalled tickets or knowledge points are highly relevant to the current complaint, reducing misjudgments.
`HTTP Request Timeout`	`30000 milliseconds`	External systems (e.g., CRM or HIS) may have slow API responses; this provides adequate time.

Three Common Mistakes

Symptom: The workflow frequently fails when processing uploaded PDF complaint reports, with logs showing "file parsing timeout." Reason: The PARSE_FILE_TIMEOUT_SECONDS parameter is set too low, failing to accommodate the parsing time for large or complex PDF documents.
Symptom: When calling an external API via an HTTP request in the workflow, the patient_id field from the current ticket details is not correctly passed. Reason: Incorrect variable assignment or reference path leads to the external API receiving a null value or incorrectly formatted parameter.
Symptom: The smart customer service response fails to accurately identify adverse drug reaction keywords in the patient's description, resulting in an irrelevant reply. Reason: The knowledge base segmentation strategy or recall parameters are configured incorrectly, failing to effectively extract and match key medical information from unstructured text.

How to Confirm Correct Configuration

Select typical complaint ticket data (including texts and attachments of varying lengths and complexities). Perform end-to-end tests within the workflow, observing if each node executes as expected and checking the accuracy of output results.
Simulate extreme conditions, such as uploading oversized attachments, texts containing extensive medical terminology, or delayed external API responses. Check if the workflow's error handling and fallback logic trigger correctly.
Compare the smart customer service's replies to test tickets with manual processing results. Analyze discrepancies, especially focusing on key information extraction, classification accuracy, and the reasonableness of proposed solutions. Adjust parameters like Similarity threshold (similarity threshold) and Recall count (recall count) based on these differences.
Check logs for all external HTTP requests within the workflow. Confirm that request parameters, response status codes (e.g., 200 or 4xx), and returned data structures meet expectations, particularly regarding variables assignment.
