What the data for this category looks like
The data sources for snack food research reports include public research reports from securities firms, public data from offline retail monitoring institutions, and industry information disclosed by supply chain manufacturers. Update cycles vary: retail monitoring data is updated weekly, securities firm research reports are released quarterly, and supply chain data is updated monthly. Each individual document includes modules such as category division, channel structure, cost composition, and consumption trends. Fields include category name, monitoring cycle, channel type, cost item, and consumer group tags. Market size is counted in ten thousand yuan, and cost items are measured in yuan per kilogram.
What constraints these characteristics impose on the "citation source and traceability" link
Data from multiple sources requires clear identification rules to avoid mixing research reports and monitoring data from different channels. Content with different update frequencies needs to have its release or monitoring cycle marked during traceability to prevent the use of expired data. The multi-module structure of documents requires retaining the complete semantics of a single module when segmenting, ensuring that the corresponding content can be accurately located during citation. The large number of sub-categories requires traceability information to include specific sub-category tags to avoid vague citations of entire documents. Differences in units require retaining the original statistical units to prevent distortion of traceability information after conversion.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
retrieve_top_k | Top 8 entries | There are many sub-categories of snack foods, so more relevant content from sub-categories needs to be covered to avoid missed recalls |
source_tag_field | category, publish_date, data_source | Snack food research reports come from diverse sources, so category, release time, and data source must be marked simultaneously to ensure accurate traceability |
parse_chunk_size | 1000–1200 characters | Snack food research reports contain multi-module content, and a moderate segment length can retain the complete semantics of a single module, facilitating accurate traceability |
reference_display_mode | Only display document title + page number | Snack food research report documents are lengthy, and simplified display avoids redundant output while retaining core traceability information |
chunk_similarity_threshold | 0.72–0.78 | Snack food sub-categories have high keyword overlap, and a moderate threshold can filter irrelevant recalls while retaining traceability basis for highly relevant content |
max_reference_per_response | 3 entries | Control the number of citations per response to avoid excessive traceability information interfering with reading |
The parameter values provided on this page are common recommendations for establishing configuration starting points. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: Forged citation IDs that cannot match the knowledge base appear in responses, and no corresponding source records are found in logs. Cause: The
source_tag_fieldparameter is not configured, or classification, release time and other tags are not correctly added to knowledge base documents, causing the system to fail to generate valid citation identifiers. - Phenomenon: The input content contains the phrase "citation mark: [1]", and the original mark is retained during output. Cause: The
reference_display_modeparameter is not correctly configured, and the display logic of original marks is not turned off, causing the marks in the input to be output directly. - Phenomenon: Documents from different sources in the knowledge base cannot be accurately distinguished in logs, only general document IDs are displayed. Cause: The
source_tag_fieldis not configured to include data source fields, causing logs to fail to record specific source types.
How to confirm the configuration is correct
- Upload a snack food sub-category research report to the knowledge base, view the parsed document details, and confirm that the content of the
category,publish_date, anddata_sourcefields is included. - Initiate a query targeting a specific snack food sub-category, view the citation information in the response, and confirm that only the document title and page number are displayed, with no additional original citation marks.
- View the system operation logs, confirm that each citation includes complete category tags, release time, and data source information, with no missing or abnormal identifiers.
- Adjust the
chunk_similarity_thresholdto the configured range, verify that the recalled citation documents are highly relevant to the queried sub-category, with no cross-category irrelevant content.
