HTTP Interface and External Systems for Automated WeChat

Data Characteristics for This Category

Data for biomedical data distribution typically includes research reports, clinical trial results, drug specifications, and academic papers. These documents are often in formats like PDF, DOCX, and Markdown. They have complex internal structures, frequently containing numerous tables, images, and specialized terminology. Data sources are diverse, including internal R&D platforms, public databases, and partner organizations. Update frequencies vary; new drug development progress or regulatory changes can lead to high-frequency updates, while basic theoretical data remains relatively stable. Fields and units have strong industry-specific characteristics, such as dosage units mg/kg, time units h, and biological activity indicators IC50, EC50. Complex medical or chemical nomenclature often accompanies these.

Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"

The complex structure and multi-format nature of the data require the HTTP interface to have robust file parsing capabilities. It must accurately extract text, table data, and image descriptions. High-frequency data updates necessitate interface support for incremental synchronization or event-driven update mechanisms to avoid resource consumption from full synchronization. The specialized terminology and measurement units demand data validation and standardization from the interface to ensure accurate information transfer. When integrating external systems, consider the authentication and authorization mechanisms of different data sources to ensure data security. Because data may contain sensitive information, the interface layer needs strict access control and support for encrypted data transmission to meet compliance requirements. Uploading and parsing unstructured data like voice and images also require the interface to have corresponding processing capabilities, such as extracting image content into searchable text or transcribing voice into text.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale for Recommendation
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Accommodates potentially large research reports or clinical trial documents, ensuring smooth large file uploads.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Allows sufficient time for parsing complex PDF or DOCX files, preventing parsing timeouts.
`maxContext`	`8000 tokens`	Biomedical data often has strong contextual relevance, requiring accommodation of longer text segments.
`chunkSize`	`500 characters`	Balances semantic completeness and retrieval efficiency, preventing information loss from overly short chunks.
`similarityThreshold`	`0.75`	Ensures highly relevant retrieved documents for user queries, filtering out vague matches.
`reRankCount`	`Top 10 entries`	Reranks initial retrieval results to improve the accuracy of the final output.

Three Common Pitfalls

Uploaded PDF documents fail to parse table data correctly, leading to missing information. This occurs because the interface's file parsing module has insufficient compatibility with specific table structures.
Images uploaded via API appear corrupted or inaccessible during preview. This happens when the returned URL path does not match the actual storage path or lacks necessary authentication parameters.
When calling the api/v1/chat/completions interface for streaming data, the frontend cannot render content in real-time. This might be due to improper handling of Content-Type: text/event-stream responses.

How to Verify Configuration

Upload a PDF document containing complex tables and multiple pages. Check if the knowledge base correctly extracts all table data and text content, and verify field values.
Upload at least 5 different formats of materials (e.g., DOCX, Markdown, PNG images) via the HTTP interface. Individually verify that they are accessible in the system, their content is complete, and they are retrievable.
Simulate a user query in a WeChat Work group involving recently updated materials. Check if the system responds promptly and provides the latest version of relevant documents, verifying the material's update time.
Test the system's response to queries containing biological professional terminology. Confirm that the results include key fields like IC50 and gene sequence, and verify their accuracy and relevance.
