Workflow Orchestration for CRO Regulations

Data Characteristics

CRO (Contract Research Organization) regulatory and SOP (Standard Operating Procedure) data primarily originates from internal R&D, quality management, and operations departments. This data typically consists of documents in formats such as Word, PDF, and Excel. Update frequency for these documents is relatively low, usually occurring quarterly or annually in response to regulatory changes, project adjustments, or internal process optimizations. Some core SOPs might be updated only every few years.

Document structure commonly includes standard components like titles, chapter directories, main text, appendices, and revision histories. Common fields and units include version numbers, effective dates, revisers, approvers, clause numbers, definitions, responsibilities, operating procedures, and record-keeping requirements. When information involves time or quantity, units like "days," "times," or "milliliters" are explicitly stated.

Constraints Imposed by Data Characteristics on Workflow Orchestration

The low update frequency of CRO regulatory documents means that knowledge base index rebuilding does not need to be frequent, thus reducing resource consumption. Standardized document structures facilitate the extraction of key information through preprocessing steps, such as automatically identifying chapter titles and revision histories. This provides more precise context for subsequent question answering.

The presence of fields like version numbers and effective dates requires the workflow to support filtering based on time or version during retrieval. This ensures users receive currently valid or specific versions of regulations. Additionally, content like operating procedures and record-keeping requirements often appears in lists or flowcharts. The workflow needs to process such structured information to provide clear, actionable guidance in responses. For scenarios involving multi-parameter calls, the workflow requires a flexible parameter supplementation mechanism to handle differing inputs that various regulations or SOPs might require.

Configuration Guidelines

Configuration ItemRecommended ValueRationale
Chunk size500–800 charactersCRO regulatory documents often have long paragraphs with detailed descriptions; this length helps maintain semantic completeness.
Recall countTop 8–12 entriesRegulatory question answering demands high accuracy; increasing the number of recalled items improves the probability of relevant recall.
Similarity threshold0.78–0.85This avoids retrieving similar but not entirely relevant regulatory clauses, ensuring precision in question answering.
Rerank result countTop 5 entriesAfter re-ranking, selecting the few most relevant items for the user reduces information overload.
PARSE_FILE_TIMEOUT_SECONDS600 secondsCRO regulatory files can be large, requiring longer parsing times; this ensures large files are fully processed.
maxContext4096 tokensComplex regulatory questions may require a long context for reasoning, ensuring the model has sufficient information.

Common Pitfalls

  • Symptom: User-set parameter values are lost in subsequent conversations. Cause: The workflow does not persist session variables or global variable storage scope is incorrectly configured.
  • Symptom: Workflow debugging results do not match actual front-end test results. Cause: Configuration parameters (e.g., model version, plugin version) or data source versions differ between the debugging and production environments.
  • Symptom: Knowledge base query results cannot precisely extract specific content from a file, sometimes returning entire paragraphs. Cause: The knowledge base segmentation strategy is too coarse, failing to perform fine-grained splitting, leading to overly broad retrieval granularity.

Verification Steps

  • Select multiple typical regulatory and SOP question-answering scenarios. Verify that the workflow accurately identifies and cites relevant regulatory clauses. Check if responses include key fields like version numbers and effective dates.
  • Test multi-parameter call scenarios of varying complexity. Confirm that the workflow can supplement all necessary parameters through interactive questioning and correctly execute subsequent operations.
  • In a simulated production environment, conduct permission tests for different user roles. Ensure that question-answering results align with access permission settings and do not disclose sensitive information.
