What the data for this category looks like
Data sources for commercial vehicle research reports mainly include public statistics from industry associations, official announcements from automakers, operational data from third-party professional research institutions, and road transport monitoring databases of the Ministry of Transport. Update frequencies cover three categories: monthly (sub-model sales, operational frequency), quarterly (cost structure, policy analysis), and annual (industrial planning, penetration rate analysis). Document structures focus on structured tables, vehicle-specific technical parameters, and policy documents, including professional fields such as curb weight, rated load mass, and fuel consumption per 100km. Units are mostly kg, L/100km, km/year, and some research reports also include metadata such as policy document numbers and announcement release dates.
What constraints these characteristics impose on the citation source and traceability process
Commercial vehicle research reports have a high proportion of structured data and many detailed dimensions, so traceability must accurately match specific table rows, vehicle paragraphs, or policy clauses. Returning only the full document name is insufficient. High-frequency monthly updates require traceability configuration to support incremental recall, avoiding repeated loading of outdated content. Diverse field units require standardized conversion logic in the traceability link to ensure the units users receive match the original text. Additionally, the strong relevance of professional terms can lead to low-relevance recall, so parameters need to constrain matching accuracy, while retaining metadata such as policy document numbers and announcement numbers to meet the strict traceability needs of industry users.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Adapt to technical analysis in long paragraphs and table splitting in commercial vehicle research reports, prevent a single chunk from containing multiple independent data points |
recall_top_k | Top 6–8 results | Meet the recall requirements for multi-dimensional data in commercial vehicle research reports, covering modules such as vehicle models, costs, and policies |
similarity_threshold | 0.72–0.78 | Filter low-relevance research report fragments, avoid false recalls caused by similar professional terms |
enable_citation_source | Enabled | Mandatorily attach citation metadata at the end of responses, meeting the professional traceability requirements of commercial vehicle research reports |
parse_table_cells | Enabled | Parse structured tables in research reports, treat cells as independent recall units to improve traceability accuracy |
citation_display_mode | Annotate at the end of paragraphs | Match user habits of viewing data sources for individual paragraphs, corresponding to the paragraph citation function added in version 4.9.7 |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Generated responses only show citation lists without body content. Cause: The
enable_citation_contentparameter is not configured, only the traceability switch is enabled but the main text generation logic is not turned on. - The citation viewing function does not work when accessing via a no-login share link. Cause: In version 4.9.6, the
citation_public_accessparameter for no-login applications is disabled by default, and the corresponding configuration item is not manually enabled. - No citation marks are displayed at the end of response paragraphs, and multi-turn conversations cannot associate citation sources from previous research report searches. Cause:
citation_display_modeis not set to "Annotate at the end of paragraphs", thecontext_citation_bindingparameter is not enabled, and the version is not upgraded to 4.9.7 or higher.
How to confirm the configuration is correct
- Upload a commercial vehicle research report PDF, trigger a search, check if citation marks are displayed at the end of the response, and verify that the marked document name and chapter information match the uploaded file.
- Enter the application configuration page, check the switch status of parameters such as
enable_citation_sourceandparse_table_cells, confirm they match the preset configuration. - Generate a response containing table data, check that citations are linked to specific table cells instead of the full document.
- Access the application via a no-login share link, verify that the citation viewing button can normally jump to the corresponding content.
