What Data Looks Like for This Category
Financial due diligence data for the coatings and inks industry comes primarily from national and industry standard compliance documents, supplier-provided MSDS reports, enterprise formula archives, batch test records, and compliance audit documents. Data updates follow two cycles: scheduled and on-demand. National standard documents are updated every 1 to 2 years. Enterprise formula and batch data adjust based on production plans or compliance requirements. Available document formats include PDF compliance texts, structured Excel test data tables, and JSON formula parameter tables. Core fields include VOC content, adhesion grade, fineness, and weather resistance grade. Corresponding units are g/L, grade, μm, and grade respectively.
Constraints Imposed on Knowledge Base Retrieval and Recall
Mixed-format documents used for financial due diligence require retrieval to support both unstructured text matching and structured field retrieval. It must balance precise matching of compliance documents and timeliness of test data to meet the rigor requirements of due diligence reports. Data sources with different update cycles require separate full and incremental update tasks. This stops outdated compliance documents from appearing in the latest due diligence reports, which preserves the accuracy of financial due diligence. Unique fields and units require retrieval to match unit information. This prevents confusion of similar data with different units, ensuring consistency of due diligence data. Structured parsing of long documents must retain field associations. This avoids losing the correspondence between formulas and test data after segmentation, which affects the reliability of due diligence conclusions.
Configuration Settings
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single MSDS or formula document for the coatings and inks industry typically does not exceed 200 MB. Setting 500 MB covers bulk upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Structured parsing of long documents requires processing multi-page formulas and test data. 600 seconds avoids timeout interruptions |
| Segment Length | 800–1200 characters | Formulas and test data for coatings and inks have strong correlation. Segment length adapts to context requirements for field association |
| Number of Retrieved Results | Top 10 | Due diligence reports require coverage of compliance, formula, and supplier multi-dimensional data. 10 results balances information density and context length |
| Similarity Threshold | 0.75–0.85 | Precise matching of national standard compliance requirements and specific formula parameters is needed. This interval filters low-relevance results |
| Number of Reranked Results | Top 5 | Prioritize displaying the most relevant core data, which meets the rigor requirements of due diligence reports |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: Unable to specify only a specified range of documents during retrieval, with results returning full database data. Cause: Knowledge base grouping function is not configured, batch selection of specified documents for retrieval scope is not implemented, and the scenario of one-time multi-file selection is not adapted.
- Symptom: High-frequency retrieval returns a
429 Too Many Requestserror. Cause: Therequest_rate_limitparameter is not configured, exceeding the platform's default request frequency limit, and the retrieval requirements for bulk due diligence reports are not matched. - Symptom: Unable to import coatings and inks compliance documents from a third-party knowledge base, or a
500 Internal Server Errorappears when viewing knowledge base citations in chat responses. Cause: API authorization configuration for third-party data sources is not enabled, or field mapping for structured data is not enabled, and unique fields such as VOC content and fineness are not correctly extracted.
How to Confirm Proper Configuration
- Upload a single 200 MB coatings formula PDF, check that the parsing task status shows completed with no timeout errors.
- Initiate a retrieval for VOC content, confirm that the number of returned results matches the set Number of Retrieved Results, and the similarity score falls within the 0.75–0.85 interval.
- Enter the knowledge base group management interface, confirm that a dedicated coatings and inks group has been created, and this group can be selected for targeted retrieval.
- Trigger a retrieval, view the cited document content, confirm that it includes unique fields such as VOC content and fineness, with no empty field errors.
