What the data for this category looks like
Duty-free research report data primarily comes from securities firm industry research reports, publicly disclosed operation announcements from domestic duty-free operators, and official interpretation documents for off-island duty-free policies. Update cycles include fixed quarterly or annual industry reviews, plus ad-hoc updates following policy adjustments or major promotional activities. Document structure typically includes modules such as policy background analysis, regional passenger flow and revenue breakdown, core category sales proportions, and future trend forecasts. Fields include publishing institution, publication date, covered duty-free scenarios (such as off-island, in-city duty-free), core metrics including customer unit price, sales revenue, passenger flow scale, with corresponding units such as ten thousand yuan, hundred million yuan, ten thousand person-times, etc.
What constraints do these characteristics impose on the "citation source and traceability" link
The multi-source and scattered nature of duty-free research reports requires the traceability link to distinguish credibility levels between official documents and securities firm research reports, prioritizing policy-related official documents as core citation sources. Ad-hoc documents with non-fixed update cycles require configuring an automatic synchronization mechanism to ensure the latest policy adjustments and operational data can be retrieved during traceability. The existence of segmented scenario and category fields requires precise matching of the duty-free region and category scope corresponding to the research report during traceability, to avoid cross-scenario citation confusion. Some research reports cite third-party operational data, so the traceability link needs to additionally associate the original data publishing entity to fully restore the citation chain. Policy timeliness requirements are high, so the effective period of the policy must be marked during traceability to avoid citing expired content.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Knowledge base recall count | Top 6-8 entries | Duty-free research reports have long core arguments per article. Too many retrieved entries will exceed the context window, while too few will fail to cover key information |
Similarity threshold | 0.72-0.80 | Duty-free research reports contain a large number of industry-specific terms. A threshold that is too low will introduce irrelevant retail research reports, while a threshold that is too high may miss valid content for segmented scenarios |
Rerank result count | Top 3-5 entries | The most relevant authoritative research reports and official documents must be retained to avoid redundant citations interfering with answer logic |
Citation Source Filter Rule | Retain only broker research reports, official announcements | High credibility is required for duty-free policy and operational data, so non-authoritative third-party content must be excluded |
Knowledge Base Sync Cycle | Daily automatic sync | The update frequency of duty-free policies and operational announcements is not fixed. Daily synchronization can cover the latest content released ad-hoc |
Context Window Length | 8000-12000 characters | The core argument content of a single duty-free research report is usually several thousand characters. The context window must be large enough to fully embed retrieved content |
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 specific analysis. It is recommended to test on local samples before finalizing.
Three common mistakes
- Phenomenon: After connecting the local duty-free research report knowledge base, the returned answer content does not match the documents in the citation list, while the citation list correctly shows that the target research report was retrieved. Cause: The retrieved documents were not correctly embedded into the model context window, or the context window length was set too small, leading to truncation of core content.
- Phenomenon: When passing a knowledge base ID variable when calling a workflow, the system does not use the specified duty-free research report knowledge base. Cause: The variable parameter was not bound in the knowledge base search node of the workflow, causing the global default knowledge base to be called instead.
- Phenomenon: The citation list order returned by the chat interface does not match expectations, and is not sorted by credibility. Cause: The re-ranking configuration was not enabled, or no credibility weight rules were set, causing the citation order to only be sorted by basic similarity.
How to confirm the configuration is complete
- Enter the knowledge base search node of the workflow, check the variable binding configuration, and confirm that the variable parameters of the target duty-free research report knowledge base have been associated.
- Initiate a test call, pass a preset duty-free research report-related question, and check the returned citation list to confirm that it only contains securities firm research reports and official announcement content.
- View the knowledge base synchronization logs, confirm that the automatic synchronization task has run per the configured cycle, and the latest policy announcements and operational data have been archived.
- Adjust the keywords of the test question, verify that the number of returned citation lists matches the configured number of retrieved entries, and the sorting conforms to the preset rules.
