What Data for This Category Looks Like
Packaging and printing investment research data mainly comes from industry association monthly production capacity reports, raw material spot price platforms, public annual reports of printing enterprises, and equipment operation logs. Data update frequencies cover three categories: daily (raw material prices), monthly (industry production capacity), and quarterly/annual (enterprise financial reports). Documents include structured reports (such as single-sheet printing cost, format parameter tables) and unstructured process whitepapers. Fields include print format (unit: mm), paper grammage (unit: g/㎡), delivery lead time (unit: days), raw material unit price (unit: yuan/ton), and each entry is marked with issuing organization and release time.
What Constraints Do These Characteristics Impose on Citation Source and Traceability
Mixed data sources and update frequencies require distinguishing real-time and historical data for timeliness labeling during traceability, to avoid citing expired raw material quotes. Coexistence of structured reports and unstructured documents requires traceability snippets to support both precise field lookup via original SQL queries and exact positioning of document paragraphs. Specific fields and units require retaining complete unit information during traceability, otherwise the accuracy of investment research conclusions will be affected. The vertical industry data source scope requires retrieved citation snippets to focus exclusively on packaging and printing-specific parameters, avoiding irrelevant general printing industry data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
recall_top_k | Top 6-8 entries | Packaging and printing investment research data sources are vertical and fields are concentrated; too many retrieved entries will introduce irrelevant data, too few will fail to cover core investment research parameters |
chunk_size | 800-1200 characters | Packaging and printing process documents contain continuous technical parameters; segment length adapts to context requirements for associated parameters, avoiding splitting combined information such as grammage and print format |
similarity_threshold | 0.72-0.80 | Industry terminology for packaging and printing has high recognition; a threshold that is too low will introduce irrelevant industry report snippets, a threshold that is too high will miss accurate raw material quote data |
reference_include_fields | ["publishtime", "datasource", "unit"] | Packaging and printing data requires retaining release time, source organization, and unit fields to ensure complete parameter context is displayed during traceability |
mysql_result_context_length | 400-600 characters | Structured report snippets returned via MySQL calls need length control to adapt to the context window of large model outputs, avoiding truncation of critical numerical values |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Structured data returned via MySQL calls does not display original snippets, only summary conclusions. Cause: The
reference_include_fieldsparameter is not configured to include fields returned by the original SQL query, or the traceability switch for function calls is not enabled. - Symptom: The number of citations returned by knowledge base search exceeds the preset range, or the citation upper limit cannot be adjusted. Cause:
recall_top_kis incorrectly set to an unlimited value, or parameter verification rules are not locked in the knowledge base configuration page, leading to entry count overflow during calls. - Symptom: Unit or release time fields are missing from citation snippets. Cause: The
unitandpublish_timefields are not configured inreference_include_fields, resulting in only core data content being extracted during traceability.
How to Confirm Proper Configuration
- Initiate a query that includes packaging and printing-specific parameters (such as paper grammage, print format) and check if the citation module at the end of the response fully displays the data source name, release time, and unit fields.
- Adjust the
recall_top_kparameter via the test interface to verify that the number of returned citations falls within the preset 6-8 entry range, with no overflow or undercounting. - Execute a MySQL function call query and check if the response fully displays all fields returned by the original SQL, with no truncation or loss.
- Review the parsed document snippets in the knowledge base to confirm that segment length meets the 800-1200 character requirement, with no continuous technical parameters split incorrectly.
