Citation Source and Traceability for E-commerce Service

What the data for this category looks like

E-commerce service investment research data mainly comes from e-commerce platform public APIs, third-party public opinion monitoring tools, and files exported from merchant backends. Data update frequencies cover three categories: hourly (real-time sales, promotional activity updates), daily (weekly category rankings), and weekly (industry trend reports). Each document includes product ID, SKU specification parameters, real-time transaction price, cumulative sales volume, user review keywords, competitive product comparison fields, with a collection timestamp attached, and uses standardized measurement identifiers such as pieces, yuan, and percentage units.

Constraints on citation source and traceability workflows

Real-time high-frequency data requires the traceability link to bind precise collection timestamps to avoid referencing expired promotional or sales data. Multi-source document structures require traceability fields to mark both data source type and collection channel, to distinguish differences between platform public APIs, third-party tools, and merchant exported files. Multi-field measurement identifiers require traceability to associate the unit definition of the corresponding field, to prevent confusion of the same field’s units across different sources. Bulk data with duplicate SKUs requires traceability to include deduplication markers, to ensure each referenced data corresponds to only one collection link.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`Recall Count`	`Top 10-15 entries`	E-commerce service investment research data has rich fields. Excessive recall will exceed the context window limit, leading to truncation of key information
`Similarity Threshold`	`0.75-0.85`	E-commerce product attributes have high similarity. A threshold that is too low will introduce irrelevant data from non-target categories, while a threshold that is too high will fail to recall valid competitive product information
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Bulk e-commerce data files exported by merchants have large file sizes, and the parsing process takes a long time. Sufficient processing time must be reserved
`Traceability Mark Fields`	`Collection Timestamp, Data Source Type`	Full binding of data collection link information is required to ensure that the update time and source channel of the data can be traced during citation
`Rerank Return Count`	`Top 5-8 entries`	Investment research analysis needs to focus on core competitive products and core indicators. Limiting the number of entries returned after reranking improves information concentration

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and testing on appropriate samples is recommended before finalizing settings.

Three Common Configuration Mistakes

Phenomenon: When selecting knowledge base documents via variable references, target data source documents cannot be accurately matched, and there is no clear parameter explanation. Cause: Data Source Type was not added to the index filtering configuration, causing variables to fail to associate with corresponding e-commerce data documents.
Phenomenon: When calling a text content extraction component, specified fields cannot be extracted from knowledge base citation results. Cause: Traceability fields such as collection timestamp and product ID were not added to the knowledge base’s index mapping, so the component cannot read the corresponding data.
Phenomenon: The number of e-commerce data entries recalled by the knowledge base does not match the set Recall Count, with excessive or insufficient entries appearing. Cause: The configuration value of Rerank Return Count was mistakenly entered into the Recall Count parameter field, causing confusion between recall logic and reranking logic.

How to Verify Correct Configuration

Upload a single e-commerce data file exported by a merchant, check if the preset Traceability Mark Fields are included in the index configuration, and confirm the field mapping relationship is correct.
Initiate a knowledge base recall request, check if traceability information such as collection timestamp and data source type is attached to the returned results, and verify that the mark fields are functioning properly.
Adjust the configuration values of Recall Count and Rerank Return Count, initiate multiple recall tests, and confirm that the number of returned entries conforms to the expected configuration logic.
Attempt to match documents from a specified data source via variables, verify that e-commerce data from the corresponding source can be accurately recalled, and confirm that the filtering logic is working correctly.
