CDMO Data Characteristics
CDMO (Contract Development and Manufacturing Organization) product data focuses on chemical molecular structures, synthesis routes, process parameters, quality control metrics, and regulatory compliance documents. Data sources include R&D experimental records, batch production records, analytical test reports, Material Safety Data Sheets (MSDS), and registration dossiers. Update frequency typically aligns with project progress and batch production cycles. For example, new process development might update weekly, while routine production batch data generates per batch. Document structures are often structured or semi-structured, such as PDF or Word documents for experimental protocols and analysis reports, and structured data stored in LIMS or MES systems. Fields and units are highly specialized, including reaction temperature (°C), pressure (MPa), yield (%), purity (%), impurity content (ppm), and often involve chemical representations like IUPAC nomenclature or SMILES strings.
Constraints on Forms and Interaction due to these Characteristics
The specialized and diverse nature of CDMO product data imposes specific requirements on form and interaction design. First, complex chemical structures and process parameters require rich text input, structural drawing tools, or specific format uploads; standard text fields are insufficient. Second, the periodic nature of data updates means knowledge base content needs regular synchronization or incremental updates to ensure the timeliness of consultation results. Diverse document types demand robust document parsing capabilities to accurately extract key information from various formats like PDF, Word, and Excel. Identifying and parsing specialized fields and units is critical. This means form design must consider the recognition of specific named entities (e.g., chemical names, CAS numbers) and provide accurate unit conversions or explanations during interaction to avoid incorrect answers due to misunderstandings of technical terms. Additionally, referencing and querying regulatory documents requires precise matching and contextual understanding.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 500–800 characters | Ensures each knowledge block contains sufficient context while avoiding redundancy or semantic drift, especially for process descriptions and experimental procedures. |
Recall count (Retrieval Count) | Top 5–8 items | CDMO consultations often require integrating information from multiple dimensions (e.g., synthesis steps, quality standards). Increasing the retrieval count helps cover more comprehensive information. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | Highly specialized text demands high matching precision to avoid retrieving irrelevant chemical or process information, which could lead to misjudgments. |
Rerank result count (Reranked Retrieval Count) | Top 3 items | After reranking, the top 3 most relevant items usually provide effective support for answers, balancing accuracy and response speed. |
UPLOAD_FILE_MAX_SIZE | 200 MB | CDMO-related analytical reports and batch production records may contain numerous charts and data, resulting in large file sizes. Support for large file uploads is necessary. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing complex PDFs or scanned documents can be time-consuming. Extending the timeout appropriately increases parsing success rates. |
Common Pitfalls
- After a user uploads a PDF, the system displays "Document parsing failed, please check file format or content." This might occur if the PDF contains many images or is a scanned document, leading to low OCR recognition rates or a parsing timeout, preventing effective text extraction.
- When querying for a specific chemical's purity range, the answer includes irrelevant values or incorrect units. This happens when specialized fields (e.g., "purity," "impurity content") are not effectively tagged or entity-recognized in the knowledge base, preventing the model from distinguishing the context of numerical values.
- In team collaboration, new members cannot access configured knowledge bases or models. This is due to incorrect permission configurations for team members or a mismatch between the username used for invitation and the registered system, leading to permission verification failure.
Validation Steps
- Upload various CDMO-related document formats (e.g., process specification PDFs, analytical report Excels) to check if documents are successfully parsed and knowledge blocks are generated.
- Ask multiple rounds of questions about core products or process parameters to verify if the model can answer accurately and cite correct knowledge sources.
- Simulate logins for users with different permissions to test if their operational permissions for form filling, file uploads, and knowledge base access meet expectations.
- Use queries containing specialized terms and units to evaluate the model's understanding of this information and the accuracy of its responses, ensuring correct unit conversions or explanations.
