What data for this category looks like
Financial report data for the packaging and printing industry comes from legally mandated periodic reports of listed companies, monthly statistical materials from national packaging and printing industry associations, and public investor relations records of enterprises.
Update schedules follow legal disclosure requirements:
- Annual reports are updated by the end of April each year
- Semi-annual reports are updated by the end of August each year
- Quarterly reports are updated within two months after the end of each quarter
Industry statistical materials are updated monthly. Investor relations records are updated in real time as related events are held.
Common document formats are PDF and Excel. PDF documents include consolidated financial statements and business segment revenue details. Excel documents include segmented data such as regional production capacity and shipment volume.
Available fields include reporting period, operating revenue, raw material procurement costs, printing production capacity, and shipment volume. Corresponding units are reporting period identifier, RMB yuan, RMB yuan, square meters, and quantity respectively.
What constraints do these characteristics impose on citation traceability
The multi-source, multi-format nature of packaging and printing financial report data creates precise matching requirements for the citation traceability process. Differences between data source formats require the parsing workflow to support both PDF and Excel, to avoid missing data extraction due to format incompatibility. Definitions and units for segmented business fields such as printing production capacity and shipment volume must exactly match the original data source. Arbitrary adjustments will cause field ambiguity during traceability. Differing update cycles across data sources require that the specific release time of each report be marked during traceability, to ensure cited content is timely and accurate. Cross-industry semantic confusion risks require strict differentiation between packaging and printing business segment financial reports and other manufacturing sector reports, to prevent citation of irrelevant data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_MAX_SIZE | 1024 MB | Packaging and printing financial report PDFs often include multiple pages of financial attachments and business details. Single documents can reach hundreds of MB in size. This value supports complete document parsing |
RECALL_TOP_K | Top 15 entries | Packaging and printing financial reports cover multi-dimensional segmented fields such as business segments, raw materials, and production capacity. A sufficient number of candidate documents must be recalled to cover all relevant data |
SIMILARITY_THRESHOLD | 0.72–0.78 | Semantic similarity for segmented business fields must be strictly controlled, to avoid recalling general financial report data unrelated to packaging and printing |
RERANK_TOP_N | Top 6 entries | Retain core relevant documents after reranking recall results, to ensure citation sources during traceability are precise and not redundant |
SOURCE_SHOW_MODE | Display full file path and release time | Packaging and printing financial reports have strong timeliness and business segment relevance. Clearly marking source files and release nodes enables effective traceability |
PARSE_TIMEOUT_SECONDS | 900 seconds | Parsing large PDF financial reports takes significant time. This value prevents mid-process parsing interruptions |
The parameter values provided on this page are conventional recommendations that serve 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
- Phenomenon: The
source_filefield in results returned via API calls is empty or does not display the full file name. Cause:SOURCE_SHOW_MODEis not configured to display full file paths and metadata, or file names and release information were not filled correctly during knowledge base upload. - Phenomenon: The large model-generated analysis cites packaging and printing business data outside the knowledge base, or incorrectly cites content from non-target financial reports. Cause: No citation verification step was configured in the workflow, and large model generated content was not compared and verified against knowledge base document metadata.
- Phenomenon: The large model does not prioritize citing the top-ranked relevant knowledge base document. Cause: The
RERANK_TOP_Nvalue is set too small, or theSIMILARITY_THRESHOLDvalue causes the top-ranked document to fail to meet semantic matching standards.
How to confirm your configuration is correct
- Upload a packaging and printing listed company's financial report PDF and an industry association's Excel document, then check if parsed metadata includes fields such as reporting period and business segments.
- Initiate a test request for financial report analysis, and verify that returned results display the full cited file path and release time.
- Adjust the
SIMILARITY_THRESHOLDvalue, then confirm that recall results only include packaging and printing-related financial report content with no cross-industry irrelevant data. - Call the API interface, then check if the
source_filefield in returned results includes correct file names and metadata information.
