Data Characteristics for this Category

SMO (Site Management Organization) regulations and SOP documents originate from clinical trial sponsors, internal SMO quality management systems, and regulatory bodies like the National Medical Products Administration (NMPA). These documents are typically in PDF, Word, or internal knowledge base pages. Content covers clinical trial operations, data management, quality control, personnel responsibilities, and ethical review. Update frequency is relatively low, usually annually or every few years, driven by regulatory changes or internal process optimizations. Document structures are rigorous, often organized into chapters, clauses, and appendices. SOPs frequently include operational steps, responsible parties, timelines (e.g., "complete within 24 hours"), document numbers, and version numbers. The core focus is process standardization and compliance.

Constraints Imposed by these Characteristics on Tool Calling and Plugins

The low update frequency of SMO regulatory documents means real-time knowledge is not a primary requirement for knowledge base construction. However, historical version management is necessary for compliance traceability. The rigorous document structure and standardized fields allow for precise information extraction during tool calls, using regular expressions or SQL. For example, extracting the responsible person or completion deadline for a specific operational step. However, since document content is largely unstructured text, direct numerical calculations or complex logical judgments via tool calls are challenging. This requires the large language model's understanding to convert natural language instructions into executable parameters. Furthermore, regulatory questions often involve relationships between multiple documents, requiring tools to perform cross-document retrieval and information integration. When user questions involve specific time units or quantities, such as "How long until an adverse event report should be submitted?", the plugin must accurately identify and return the specific value defined in the SOP, such as "72 hours".

Three Common Mistakes

  • Symptom: API calls for multimodal conversations return a 400 invalid image error. Reason: Image file format does not meet API requirements or file size exceeds limits, preventing the model from correctly parsing image data.
  • Symptom: The network search node is enabled, but the large language model's response does not cite search results. Reason: Network search trigger conditions are not met, or the relevance score of search results to the user's query is too low, causing the model not to cite them.
  • Symptom: SQL data link tool returns a 422 Unprocessable Entity error. Reason: SQL statement syntax error, field names do not match the database table structure, or necessary query parameters are missing.

How to Confirm Correct Configuration

  • For typical regulatory queries, such as "adverse event reporting process," verify the model accurately cites relevant SOP clauses and triggers tool calls to extract key timelines.
  • Select SOP documents containing charts or flowcharts. Test multimodal question-answering to confirm image content is correctly identified and interpreted.
  • Simulate a user asking, "What are the latest NMPA regulations on clinical trials?" Observe if the network search node is activated and returns relevant external information.
  • For SOPs containing structured data (e.g., tables), build a tool with SQL queries. Verify it can precisely extract specific numerical or textual information from the table.
