What the data for this category looks like
Auto service investment research data mainly comes from manufacturer public technical manuals, after-sales maintenance databases, industry association compliance standards, terminal store operation work orders, and new energy vehicle battery health reports. The data update rhythm varies significantly: manufacturer technical manuals are updated quarterly, after-sales work order data is updated daily, and industry compliance standards are revised annually. Document structures include structured maintenance parameter tables (with fields such as VIN code, accessory model, replacement cycle, etc.), unstructured maintenance case documents, and timestamped operation records. Units involve professional measured values such as hours, millimeters, volts, etc.
What constraints do these characteristics impose on the "citation source and traceability" link
The segmented attributes of auto service investment research data require that traceability information covers vehicle adaptability, version number, and update time, to avoid citing outdated maintenance standards or mismatched vehicle parameters. Structured parameter tables need to be accurately positioned to specific document blocks, and unstructured cases need to be associated with corresponding store work order records, otherwise compliance verification for investment research decisions cannot be supported. If high-frequency updated after-sales data is not labeled with a version, it is easy to cause the cited content to be inconsistent with current compliance requirements, increasing investment research risks.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
reference_count | 3-5 entries | Auto service investment research data mostly consists of segmented professional parameters. Too many citations will interfere with decision-making logic, while too few cannot cover compliance traceability requirements |
enable_reference_version | Enabled | Auto manufacturer manuals and maintenance standards have version iterations, and version numbers need to be labeled to ensure traceability content is consistent with current compliance requirements |
reference_source_field | ["source_name", "version", "update_time", "vin_compatible"] | Auto service data needs to be associated with exclusive fields such as vehicle adaptability and update time to meet the precise traceability needs of investment research scenarios |
api_return_reference | Enabled | Investment research scenarios need to obtain cited content through APIs for secondary verification or formal report generation |
max_reference_chunk_length | 800-1200 characters | Auto service documents contain long paragraphs of maintenance steps. Overly long segments will lose context association, while overly short segments cannot cover complete parameter information |
reference_export_granularity | By document block + field dimension | Supports splitting traceability data by business category to meet refined export and import needs |
The parameter values provided on this page are conventional recommendations used 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 the settings.
Three common mistakes
- Phenomenon: The number of citations returned when calling the knowledge base does not reach the preset upper limit. Cause: The
reference_countconfiguration is not adjusted, or thesimilarity_thresholdis set too high, filtering eligible traceability data. - Phenomenon: Cited content cannot be downloaded in some scenarios in version 4.8.22. Cause: The
enable_reference_downloadconfiguration is not enabled, or the associated source document has been deleted, and the version rollback mechanism is not configured. - Phenomenon: The exported traceability data only contains overall knowledge base information and cannot be split by business category. Cause: The
reference_export_granularityis set toknowledge base dimensionand not adjusted to export by document block or field dimension.
How to confirm the configuration is correct
- Initiate a test query containing auto maintenance parameters, and check whether the returned results are attached with source document name, version number, and update time fields.
- Call the API interface for obtaining question and answer results, and confirm that the returned
referencesfield contains complete traceability information. - Perform a knowledge base export operation, and check whether the exported file is split by business category and does not only contain the overall knowledge base package.
- Adjust the
reference_countconfiguration, then initiate the same query, and confirm that the number of returned citations meets the preset value.
