Page Overview
This documentation covers model access and configuration for duty-free research report retrieval. Key context includes:
- Client industry: Duty-free
- Business direction: Research report retrieval and question answering
- Capability area: Model access and configuration
What the data for this category looks like
Duty-free research report data mainly comes from broker retail industry research reports, special survey data on duty-free formats, regular reports and temporary announcements of listed duty-free enterprises, and monthly operating briefings from industry associations. Update cycles vary by source: broker research reports are updated without a fixed schedule as institutions release them, association briefings are updated monthly, regular reports are updated quarterly or annually, and temporary announcements are triggered by industry events. A single document includes modules such as industry overview, policy interpretation, operating data, and policy impact analysis. Fields include publishing institution, release date, core operating values, original policy clauses, and survey sample size. Common units are ten thousand yuan and person-times.
Constraints on model access and configuration from data characteristics
The data characteristics of duty-free research reports impose multiple constraints on model access and configuration. First, documents contain both structured operating data and unstructured policy text. Mixed retrieval rules must be configured to balance structured field matching and semantic similarity retrieval. Second, single document length varies widely, from hundreds of words of industry briefings to tens of thousands of words of in-depth research reports. Adaptive segmentation parameters must be configured to avoid long text truncation or over-fine splitting of short texts. Third, update cycles differ significantly across data sources. Synchronization frequencies differentiated by source must be configured to match the update rhythms of each data source. Fourth, some documents have null value fields. Field filtering rules must be configured to eliminate invalid data interference with retrieval.
Configuration recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | Balances semantic integrity for both short and long duty-free research reports, avoids over-fine splitting or truncation of key content |
recall count | Top 8–12 results | Adapts to the duty-free research report retrieval scenario; too many results increase context pressure, too few will miss relevant content |
similarity threshold | 0.72–0.85 | Adapts to the professionalism of duty-free industry terminology, filters low-correlation results while retaining valid recalls |
incremental synchronization interval | Broker research reports: 12 hours, association briefings: 1 day, regular reports: 1 week | Matches the update rhythms of different data sources, avoids repeated pulling or delayed updates |
field filtering rules | Filter documents with release dates older than 365 days, or documents where null value fields account for more than 50% | Ensures timeliness and effectiveness of retrieved content, eliminates interference from invalid data |
vector model batch processing size | 10–20 items per batch | Balances memory usage and synchronization efficiency, adapts to the varying document lengths of duty-free research reports |
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 case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Error message "No available channel" or connection failure occurs during vector model access. This occurs when the vector model API address and key are not configured correctly, or the default group does not have call permissions for the corresponding model enabled.
- Context overflow or timeout occurs when calling a locally deployed model. This happens when the
maxContextparameter is not set to adapt to the long text length of duty-free research reports, or the token limit for batch requests is not adjusted. - A large number of non-duty-free industry documents are included in retrieval results. This occurs when field filtering rules are not configured, or the similarity threshold is set too low to filter content from non-target categories.
How to confirm successful configuration
- Access the model configuration page of the knowledge base, check the connection status of the vector model and LLM model, confirm both show normal connection, and verify that the configured API information matches the actually deployed model.
- Upload a single test duty-free research report document, trigger the synchronization process, check the parsing log, confirm that the document has been split according to the configured segment length, and no abnormal errors occur.
- Initiate a retrieval test, input industry-related keywords, check the number of recall results and content relevance, adjust relevant parameters to match the retrieval target.
- Call the configured model to initiate a test conversation, confirm that the model can normally read the retrieved document content and generate a response, with no context overflow or timeout prompts.
