What this category's data looks like
Paint and ink industry investment research data sources include industry association published documents, public technical parameters from upstream raw material suppliers, terminal market research records, and technical specifications released by compliant regulatory bodies. Data update rhythms vary: raw material market monitoring data updates weekly, industry dynamic reports update quarterly, and compliance technical standards update irregularly alongside policy adjustments. Document types include structured parameter tables, PDF industry white papers, and batch-exported original monitoring data. Fields include raw material grade, viscosity value, solid component proportion, and annual production capacity. Units are: no label, mPa·s, dimensionless ratio mark, and 10,000-ton annual production capacity.
What constraints these characteristics impose on the "citation source and traceability" link
Differences in data update rhythms across sources require the traceability link to label the corresponding data source update time for each citation, to avoid confusing different versions of weekly reports with the same file name. Mixed multiple document types require the parsing link to distinguish between structured parameter tables and non-technical text paragraphs, to ensure precise location of the specific document segment where the referenced parameter is located during citation. Differentiated identification of multiple fields requires traceability information to include the specific field name corresponding to the parameter, rather than only labeling the entire document. Demand for cross-data-source parameter comparison requires traceability information to clearly mark the original collector of the data, to facilitate investment research personnel to verify data credibility. Highly specialized industry terminology requires the traceability link to retain the original terminology expression from the source document, to avoid information deviation caused by simplification.
How to set the configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
segment length | 1000–1500 characters | Balances long technical specifications and short parameter entries in industry documents, avoids truncating paragraphs containing key search terms |
recall count | Top 8–12 entries | Covers multiple parameter entries in a single document for the paint and ink industry, ensures core data sources are fully recalled |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Adapts to parsing time for large industry white papers, prevents parsing failure due to timeout |
similarity threshold | 0.72–0.78 | Balances matching accuracy and recall range for specialized terminology, avoids incorrectly recalling similar but unrelated formula documents |
citation source display format | Full document path + update timestamp + field identifier | Clearly marks the specific data source, version, and parameter location of the citation, meets investment research traceability requirements |
reordered return count | Top 5 entries | Prioritizes displaying the most relevant core data sources, aligns with the quick review habits of investment research personnel |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: Structured parameter tables cannot be rendered in context-based citations, only plain text line breaks are displayed. Cause: The structured document parsing switch is not enabled, and documents are segmented only according to plain text rules.
- Issue: After submitting a test query containing specific parameter keywords, the system returns no knowledge base-related results, returning an empty response. Cause: The similarity threshold is set too high, or the segment length is too long, truncating the paragraph containing the key search term.
- Issue: Citation sources only display the file name, without including the update time and corresponding field identifier, making it impossible to distinguish different versions of weekly reports with the same file name. Cause: The extraction rules for data source update timestamps and field identifiers are not configured.
How to confirm the configuration is complete
- Upload a standard paint and ink industry weekly report document, check that the parsed segments retain complete parameter entries with no truncation.
- Submit a test query containing specific parameter keywords, verify that the number of recall results falls within the configured recall count range.
- View the source column of each citation, confirm that it includes the full document path, update timestamp, and field identifier of the corresponding parameter.
- Adjust the similarity threshold and submit a test query, verify that the relevance of the recall results aligns with the preset judgment standards.
